The short answer: match the blade to your mower brand and its blade style, then replace the mounting screws at the same time and add threadlocker. That is where nearly every blade complaint starts and ends. Get the fit wrong and the blade will not pivot freely, which is the safety feature that stops a hidden stick from snapping an arm.
Robot mower blades are cheap, and they are the single biggest lever on how your lawn looks. Standard steel blades last roughly six to eight weeks, titanium-coated blades run four to six months, and heavy-duty or tungsten carbide options can reach a full year. Choosing the right material decides how often you tip the machine over and whether the turf stays healthy or slowly browns at the tips.
We compared 12 packs of replacement blades for robotic mowers across OEM factory parts, titanium-coated aftermarket blades, and bulk multi-fit sets. If you have not bought a robot yet, our guides to the best electric robotic lawn mowers and the best robotic lawn mowers for large lawns cover the machines that consume most of these blades.

1. Husqvarna Endurance Blades: the Factory Choice for Automower Owners
Husqvarna 595084411 Endurance Automower Blades, Silver
OEM carbon steel
Four cutting edges
6 blades plus screws
22.68 g per blade
Pros
- Genuine Husqvarna part
- Sharp four-sided edges
- Claimed over twice the life of classic blades
- Phillips head install only
- Blades and screws supplied together
Cons
- Small pack means more frequent orders
- Premium over titanium aftermarket sets
- Durability gap versus coated blades debated by some owners
These are the blades Husqvarna builds for its own machines, part number 595084411, and that origin is the whole argument for them. The carbon steel is hardened for a crisper edge without compromising the pivot behaviour, and all four sides of each blade cut, so the blade clips a little grass at a time rather than tearing at it.
Husqvarna claims the Endurance design lasts more than twice as long as the classic blades that shipped with older Automower models. Owners reviewing verified purchases generally back that up on cut quality, reporting an even lawn pattern and a swap that needs nothing more than a Phillips head screwdriver.
What you are paying for is certainty. This is the one option in the roundup where fit is not a question, because it is the part the machine was engineered around, and the 511 reviews at a 4.6 average make it the best-evidenced pick here.
The honest drawback is pack size. Six blades covers fewer replacement cycles than the 30 and 36-piece aftermarket sets, and a handful of owners argue the durability edge over titanium-coated aftermarket blades is smaller than the price difference implies. If your budget is tight and your mower is not an Automower, look further down this list.
Who the Husqvarna Endurance Pack Suits
Automower owners with a working set of screws and a clean pivot post. Nothing about the install is difficult, and the pack ships the blades and screws together, which removes the most common reason a swap gets abandoned halfway.
It also suits anyone who wants the shortest possible decision. There is one blade part for every Automower model, so there is no model number to cross-check and no aftermarket listing to interrogate. For a machine that cuts unattended, that predictability is worth more to us than extra blades in the box.
What to Watch Out For With This Pack
Six blades is the smallest pack in the roundup, and on a large lawn mowing daily it will run out between seasons. Budget for ordering twice a year, or keep the factory screws from the old set and mix with a bulk aftermarket pack if your model allows it.
Do not expect a titanium-level corrosion story. Carbon steel rusts faster in humid yards, and owners on r/automower describe the stock blades on their machines showing flash rust within weeks. If your lawn stays wet, the coated aftermarket sets are the better long-term buy.
2. FourShow 36-Pack for Mammotion Luba and Yuka: the Best Value Per Blade
FourShow 36Pcs Replacement Blades Compatible for Mammotion Luba & Yuka All Series, Robust Titanium Replacement Robotic Lawnmower Blades, with Plastic Washers
0.9 mm blade thickness
Stainless with titanium carbide alloy
36 blades, washers included
Pros
- Very large 36-blade pack
- Thicker than most aftermarket blades
- Galvanized screws and washers
- Cut reported equal to factory Mammotion blades
- Variant options per series
Cons
- Some blades bend on sticks after a few weeks
- Occasional stripped screw heads on removal
- One report of poor fit on the AWD 3000
- Mini-series disc has 7 fixing points not 6
This is the pack that makes blade ownership stop being an event. Thirty-six blades plus galvanized screws and plastic washers means you can change monthly without thinking about it, which is exactly the habit owners on r/automower describe swapping cheap aftermarket blades on a routine basis.
The spec worth knowing is the 0.9 mm blade thickness. Most competing aftermarket blades sit around 0.75 mm, so this is a noticeably stiffer blade that resists flex, and the stainless steel with titanium carbide alloy adds both corrosion and shatter resistance compared with plain carbon steel.
Owners of Luba 2 and Luba Mini machines mostly report cutting that matches the factory blades, which is the benchmark that matters. At 420 reviews and a 4.3 average, this is the most-reviewed Mammotion-specific option we found, and the rating holds up across most of the model range.
The screws and washers are the part of the box that separates it from cheaper kits. The galvanized screws, safety varnish, and plastic washers are all specified to resist corrosion and vibration loosening, which addresses the two complaints that show up most often on aftermarket blade packs.
Who the FourShow Mammotion Pack Suits
Luba 1, 2, and 3 owners plus Yuka and Yuka Mini owners who want to stop thinking about blade stock. At this count, one set covers multiple years on a normal cutting schedule, and the compartmented layout keeps the screws separated.
It suits owners of yards with weedy, dandelion-heavy lawns too. The titanium carbide alloy resists the chipping that happens when a blade catches a stem or a woody weed base, which is the failure mode that ends thin blades early.
What to Watch Out For With This Pack
Check your model before ordering. A small number of reviews report fit problems on the Mammotion AWD 3000, which uses thinner and longer screws than the stock hardware, and the Luba Mini disc carries seven fixing positions rather than six with a raised centre bump.
Some owners on stick-heavy ground saw blades bend after a few weeks despite the thicker steel, and a few had screw heads shear during removal. Work the screws out with penetrating oil and steady pressure rather than force, and check the pivot by hand after fitting.
3. Headley Tools 30-Pack: the Widest Brand Coverage in One Bag
Headley Tools Replacement Robotic Mower Blades (Titanium Coating) for Husqvarna Automower,Gardena Robot Mower, Compatible with Segway Navimow Robotic Mower, Pack of 30
Titanium-coated stainless steel
30 blades plus 30 screws
5.94 x 5.59 x 3.9 inches
Pros
- Fits Automower Gardena and Navimow families
- Titanium coating slows flash rust
- 30 blades plus screws per pack
- Smooth edges with minimal torn tissue
- Long-standing repeat purchase history
Cons
- Some owners find edges dull faster than OEM
- Screws can loosen without threadlocker
- Minority report cut quality below stock
- Awkward access on some mower bodies
Headley Tools has been selling this pack since June 2018, and the 413 reviews behind it are the reason it stays on our list. It is the practical choice when you own one mower but a neighbour, a relative, or a rental property runs a different brand, because the same 30 blades cover Husqvarna Automower, Gardena, and Segway Navimow families plus YARDCARE units.
The titanium coating over stainless steel is the real feature here. It slows the flash rust that owners on r/automower describe on stock blades in humid yards, and long-term buyers commonly report two to four times the life of their original set at a similar unit price.
The physics behind a pivoting razor blade explain why these work well. Each blade is mounted on a small arm so that a stick deflects it sideways instead of shearing it, and the smooth ground edge leaves fewer ragged tips than a stamped steel blade with a rougher finish.
Thirty blades plus thirty screws means you can pair them up or run them singly depending on what your arms allow. That flexibility is why so many owners treat this as a standing subscription rather than a one-off purchase, and why the review base has grown over seven years.
Who the Headley Tools Pack Suits
Homes with more than one robot mower, or owners who split blades between machines on different brands. Very few aftermarket packs cover Automower, Gardena, and Navimow with the same blade, and this one has been doing it longer than anything else in our list.
It also suits owners in wet or coastal climates. The titanium coating is the practical answer to the rust complaints that appear on r/automower threads, where users report stock blades deteriorating in storage before they even reach the ground.
What to Watch Out For With This Pack
Several owners report the edges dulling faster than OEM blades on very thick turf, so if you mow heavy warm-season grass, expect to check them sooner than the four-to-six-month figure suggests.
The supplied screws can back out during operation unless you add threadlocker, and on some mower bodies the arm sits in a tight space that makes the swap awkward. A small number of buyers also found the cut quality below their previous stock blades once the edges wore in.
4. EMBerg Endurance 18-Pack: Dual-Ended Blades for Debris-Heavy Lawns
EMBerg Endurance Blades (18 Pack) for Husqvarna Automower Gardena McCulloch Robotic Lawnmower Mowing Lawn Mower Robo Robot Accessories Replacement Blade for 315 430 435 450 Others. (Titanium Coated)
Dual-ended stainless or titanium
2.68 x 2.13 x 0.67 inches
18 blades plus screws
Pros
- Dual-ended design doubles cutting area
- Flippable for a second edge
- Stainless and titanium versions
- Blades and screws included
- Broad Automower Gardena McCulloch fit
Cons
- Longevity only modestly better than OEM on some units
- A small number report grass tearing once worn
- Availability split across two material versions
The idea here is simple and it works: both ends of the blade cut as it spins, so a single blade delivers roughly twice the cutting area of a conventional single-ended blade, and you can flip it over to reach a fresh edge. Across 18 blades you get an unusually large number of usable cutting edges for the money.
This is the set we would reach for on a yard with pine needles, sticks, and dandelions, where the cutting arm meets hidden debris more often. Reviewers credit the double-ended geometry with a noticeably cleaner cut and longer service life than a plain single-ended aftermarket blade.
Fit spans Husqvarna Automower, Gardena, and McCulloch models, and the set ships with matching screws so a full swap takes one session. The 4.5 average across 174 reviews sits comfortably among the highest-rated products in this roundup, with 81 percent of ratings at five stars.
Both material versions are worth knowing about. The stainless option is the sensible default for most lawns, and the titanium-coated version is the one to pick if your ground stays damp or you are storing blades over a wet winter.
Who the EMBerg Endurance Pack Suits
Owners of pine-heavy or debris-heavy yards, and anyone who prefers fewer, larger blades over a cloud of tiny ones. The double-ended design means 18 physical blades behave closer to 36 in terms of usable edge, which simplifies storage and counting.
McCulloch owners get a bonus here, because that brand shares the Automower blade footprint and is often left out of multi-brand aftermarket listings. This one covers all three families in the same box.
What to Watch Out For With This Pack
A minority of users find the longevity only modestly better than OEM blades, and a small number report grass tearing once the blades wear down, which is the same warning that applies to any consumable edge past its prime. Check the lawn rather than the calendar.
Make sure you pick the right material listing, since the design is offered in both stainless and titanium-coated versions and only one is in the box you receive. Store them dry between seasons if you go with the stainless option.
5. ECOVACS GOAT Blade Kit: the Right Part for O1000, A2500, and A3000
ECOVACS Goat Robot Lawn Mower Blades Kit for O1000 RTK/A2500 RTK/A3000 LiDAR
Stainless steel
Part GBK120001
1.95 inch to 3.6 inch cut height
3.6 inch cutting width
Pros
- Genuine ECOVACS part for GOAT models
- Installs in a few minutes
- Restores cut once OEM blades dull
- Stainless steel construction
- Compact kit with 3.6 inch cutting width
Cons
- Rating score is modest at 4.0
- Most reviews cover the mower not the kit
- Limited to three GOAT models only
ECOVACS builds the GOAT O1000 RTK, A2500 RTK, and A3000 LiDAR on their own cutting platform, and this kit, part GBK120001, is the factory answer for those three models. The blades are stainless steel with a listed 3.6 inch cutting width and an adjustable cut height from 1.95 to 3.6 inches.
Reviewers who comment on the blades directly report a proper fit and a fast install, and a common note is that swapping in a fresh kit restores cutting performance once the originals have dulled. Given how often robot mower blades are changed, keeping a spare of this kit on hand is a reasonable habit.
The stainless steel construction is a sensible match for the GOAT platform. Stainless trades a small amount of edge hardness for noticeably better corrosion resistance, which matters on a machine that lives outdoors through a wet season and is expected to be left on the lawn.
The low cut height range is worth flagging before you buy. This kit supports 1.95 to 3.6 inches, and owners running cool-season lawns note that a maximum around 3.2 to 3.6 inches is low compared with a conventional mower, so the blade is not your limiting factor there.
Who the ECOVACS GOAT Kit Suits
Owners of the O1000 RTK, A2500 RTK, or A3000 LiDAR who want the original part and a guaranteed fit. The blade geometry on these machines is not shared with other brands, so this is genuinely the safest route rather than merely the most cautious one.
It also suits anyone restoring performance on a mower that has been running with dull blades. Reviews describe a visible improvement in the finish after fitting a new set, which is the clearest signal a blade change is due.
What to Watch Out For With This Kit
The evidence on this blade specifically is thin. Most of the 154 reviews in this listing discuss the GOAT mower rather than the consumable, so a 4.0 average tells you more about the listing than about the steel. Judge it on fit confidence rather than on star count.
None of the mower complaints transfer to the blade, but they do affect your overall experience: app-based manual mapping is described as awkward, edge trimming along fences is unreliable, and the maximum cut height is low. If you own one of these three models, the blade choice is one of the few parts you do not have to think about.
6. WORX WA0190 Landroid Kit: Flippable Blades for the WG794
WORX WA0190 1″ Landroid Replacement Cutting Blade, 12Piece Blade Kit with Screws, Fits: Landroid Series (WG794)
Alloy steel
Part WA0190
1 inch L x 0.75 inch W
12-piece kit with screws
Pros
- Matches original manufacturer blades
- Two-sided blades flip to double the pack
- No special tools for the swap
- Fits the WG794 Landroid cleanly
- Extra screws included
Cons
- Included screws can be hard to remove when rusted
- Premium per blade versus generic 30-packs
- Some owners double blade count with added washers
The WORX WA0190 is specified for the Landroid WG794, at 1 inch long by 0.75 inch wide in alloy steel with 1 mm thickness. The Landroid runs three blades at a time, and the kit gives you twelve, so you are covered for several complete sets.
The useful detail is that these blades are two-sided. When one edge dulls you flip the blade and get a second cutting edge, which effectively turns a 12-pack into 24 uses. Owners confirm the cut performance matches the original WORX blades.
Fit is the strongest reason to buy factory here. The Landroid pivot post and screw shoulder are matched to this blade, and at 4.4 across 135 reviews the satisfaction level is solid for an OEM consumable.
The most repeated complaint is not the blade, it is the screw. Owners report the supplied screws are hard to remove once rusted or firmly seated, so soak them with a penetrating oil before you turn the screwdriver. Several owners add washers and run two blades per arm to compensate for wear, which is a debated approach we cover in the buying guide.
Who the WORX WA0190 Kit Suits
Landroid WG794 owners who want OEM geometry and do not want to count blade cycles. With three blades on the machine at any time, a 12-piece kit with flippable edges gives you a long stretch before the next order.
It is also the right kit for the one-blade-or-two debate. Because the blades are two-sided and the correct size, owners can run a single blade per arm when the lawn is thin and pair them up when the turf is heavy, without buying a second product.
What to Watch Out For With This Kit
The per-blade cost is higher than the generic 30-piece aftermarket kits in this roundup, so you are paying for fit certainty rather than volume. That is a fair trade on a machine whose arms do not accept every blade shape.
Plan the removal carefully. Rusted or well-seated screws are the single most repeated complaint, and other Landroid owners on r/worxlandroid are actively hunting replacements to improve the cut on tough Bermuda. Removing the battery first is part of the correct procedure.
7. KuddinX 30 Sets for Mammotion: Thicker Blades for Tough Warm-Season Turf
Kidding – 30 sets Robust Titanium Blades for Robotic Lawn Mower – Compatible for all Mammotion models Luba 1,2,3 AWD Luba mini AWD Yuka mini 1,2 and Yuka models
0.9 mm blade thickness
Titanium-coated stainless steel
1.41 x 0.74 x 0.05 inches
30 sets
Pros
- 0.9 mm blades versus 0.75 mm rivals
- Clean cut with no torn edges
- Longer unthreaded section sheds packed grass
- Sharp out of the box
- Compartmented storage box included
Cons
- A few units rusted faster than Mammotion OEM
- OEM plastic washer not included so pivot fit varies
KuddinX builds to precise measurements for Mammotion Luba 1 and 2 plus the Yuka series, and the 0.9 mm blade thickness is the headline. Competing aftermarket blades commonly measure 0.75 mm, and the manufacturer claims a 50 percent longer life from the extra material, which tracks with the thicker design used in our number two pick.
Owners report a clean cut with no torn edges and good durability on Luba 2 machines, and a design detail worth noting: the longer unthreaded section means less grass packs underneath the blade, so the arm stays cleaner between changes. The blades also arrive sharp rather than needing a file.
Thirty sets is a lot of consumable, and the fit is reported as perfect on Luba 1, Luba 2, and Yuka machines. German and international owners in particular describe a smooth, healthy cut, which is a useful signal given how variable aftermarket blade quality usually is across regions.
The divided storage box for blades and screws is a small touch that matters more than it sounds, because loose blades scattered in a drawer are how people mix up screws and washers between models and then wonder why a blade will not sit flat.
Who the KuddinX Set Suits
Mammotion owners on thick warm-season turf who are tired of torn tips. The 0.9 mm steel holds an edge through crabgrass and dense Bermuda better than the thinner blades most listings ship, which is the complaint that appears across cheaper sets.
It suits high-mowing-frequency households too. At 30 sets, the stock lasts far longer than a season on a machine that mows every day, and the sharper factory edge means fewer scheduled swaps in the first place.
What to Watch Out For With This Set
A small number of reviewers on this listing report faster rusting than the Mammotion OEM blades, which is worth knowing if you are in a wet climate. Store the unused sets somewhere dry rather than in the shed.
The OEM plastic washer is not included, so the fit at the pivot shoulder varies slightly. Reuse the washer from your existing blade if you want the factory feel at the pivot, and check the arm swings freely before you power up.
8. FourShow 36-Pack for Husqvarna: Long-Hole Blades You Can Flip Four Ways
FourShow 36Pcs Endurance Blades Compatible with All Husqvarna Lawn Robots, Durable Titanium Replacement Blades, Including Screws with Safety Coating
Stainless with titanium carbide alloy
Long-hole flippable design
36 blades with screws
0.79 x 1.97 x 0.39 inches
Pros
- Long-hole design allows up to four uses per blade
- Screws tighten smoothly without stripping
- Sharp out of the package
- Holds a clean cut over multiple cycles
- Blades can be repositioned to tune the cut
Cons
- One review found blades dull within a week
- Occasional reports of tearing on thick Bermuda-type turf
This is the Husqvarna and Gardena answer for owners who want volume. Thirty-six blades in stainless steel with a titanium carbide alloy, and the long-hole mounting design means a single blade can be flipped and repositioned for up to four uses rather than two.
The hardware is the quiet strength. Reviewers repeatedly single out the galvanized screws with anti-rust coating and safety varnish, reporting they tighten smoothly without stripping, which is a change from the aftermarket kits that ship with frustrating screws. The coating is there specifically to resist vibration loosening over the season.
Owners of Husqvarna 430X and Gardena R45Li report cutting equal to the OEM blades at a fraction of the ongoing cost, and the 36-blade count means a monthly swap is genuinely cheap. The 4.4 average across 94 reviews is consistent with the wider FourShow range in this roundup.
Because the mounting hole is a long slot rather than a single round hole, you can slide the blade along the screw to change the effective cutting position. Owners use that to tune the balance on their particular machine, which is a real advantage when the arm runs slightly uneven.
Who the FourShow Husqvarna Pack Suits
Automower and Gardena owners who mow often and would rather not order consumables twice a year. Thirty-six blades, each with up to four usable positions, means the pack behaves like a much larger one over a full season.
It suits anyone who has been frustrated by stripping aftermarket screws. That is the most common mechanical complaint in this category, and this pack is the one in the roundup where owners consistently report screws that tighten smoothly.
What to Watch Out For With This Pack
One reviewer found the blades much less sharp than advertised after a week of use, and a small group on heavy turf reported faster wear and grass tearing. If your lawn is thick warm-season grass, the longer-blade option in pick ten is a better bet than more quantity.
Also expect to centre each blade carefully on the screw shoulder during fitting. The positional freedom that gives you four uses is the same feature that makes it easy to install a blade slightly off-square, and an off-square blade is the first thing to check if cut quality looks uneven.
9. FourShow 36-Pack for Segway Navimow: Correct Fit Across the i and H Series
Pack of 36 Replacement Blades Compatible for Segway Navimow i105N, i108N, i110N, H500N, H800N, H1500N, H3000N, Roborock RockNeo Q-serie RockMow X-serie, Robotic Lawn Mower Blades, Titanium Gold
Stainless with titanium carbide alloy
36 blades with screws
8 x 6 x 1 inches
Model GCJ-043
Pros
- Covers Navimow i105N through H3000N series
- Roborock RockNeo and RockMow compatible
- Very sharp out of the box
- Reported to stay sharp longer than OEM
- Galvanized anti-corrosion screws
Cons
- Supplied screws can stop blades pivoting freely
- Round mounting holes need careful centring
- One reviewer found blades less sharp than OEM due to thickness
Model compatibility is spelled out unusually well here, covering Segway Navimow i105N, i108N, i110N, H500N, H800N, H1500N, and H3000N, plus Roborock RockNeo Q-series and RockMow X-series. That level of specificity is exactly what owners in r/SegwayNavimow ask for and rarely find on a listing.
On sharpness, most Navimow owners report blades that arrive very sharp and hold that edge longer than the factory set. The titanium gold finish over stainless steel with titanium carbide alloy handles corrosion well, which matters in damp climates.
The 36-blade count suits machines that need frequent swapping, and the galvanized screws with safety varnish are included in the box for a complete swap. The stated model is GCJ-043, and the pack measures 8 by 6 by 1 inches.
Worth knowing why the fit claims matter more on Navimow than elsewhere. The i-series and H-series machines share this blade footprint, which means a single purchase covers a lot of ground, but Roborock units are a separate fit and mixing the two families is a common ordering mistake.
Who the FourShow Navimow Pack Suits
Anyone who has struggled to work out which blade a Navimow takes. The series letter and number are listed explicitly, which removes the guesswork that pushes owners toward generic packs that turn out not to bolt on correctly.
It also suits households running a Navimow alongside a Roborock unit, because both are covered in the same box. That is unusual, and it is the reason this pack edges out the broader multi-brand options for those owners.
What to Watch Out For With This Pack
Some buyers found the included screws prevented the blades from pivoting freely and fell back to their original screws or threadlocker. Test each blade by hand after fitting, and use your original screws if the new ones bind the pivot.
The round rather than oblong mounting holes mean you need to centre each blade carefully on the screw shoulder. One reviewer also found the blades less sharp than OEM because they are thicker, which is the trade for durability at 36 pieces in the box.
10. EMBerg Monster XL 18-Pack: Longer Blades for an Overlapping Cut
EMBerg Monster XL Blades (18 Pack) for Automower Models as Well as Gardena and McCulloch Robotic Lawnmowers. (Titanium)
43 mm blade length
1.69 inch L x 1.69 inch W
18 blades plus screws
Titanium
Pros
- 43 mm blades overlap the cutting disc
- Longer blades give more cutting inertia
- Easier to re-sharpen with a file than OEM
- Works beyond Automower into GOAT and Anthbot
- Matching screws included
Cons
- Longer blades add strain so check clearance first
- One reviewer says edges do not hold like OEM
- Included screws shorter than OEM due to built-in shoulder
These blades measure 43 mm, which is 8 mm longer than the standard 35 mm blade most robot mowers use, and that extra length is the entire point. Longer blades overlap the cutting disc path, so you lose the uncut strip of grass down the middle that owners with standard blades often live with.
The extra length also produces more cutting inertia, which is why long-term owners report the blades handling crabgrass, thick grass, and small weeds far better than a short blade can. At 4.5 across 85 reviews this is one of the highest-rated products in the roundup.
Two details make it more than a length trick. The titanium steel is easier to re-sharpen with a file than OEM hardened steel, so you can rescue a tired blade instead of binning it, and the fit extends beyond Automower into ECOVACS GOAT O1000 and Anthbot Genie 600 units.
Long-term owners single out the overlapping cut as the main quality-of-life improvement, and crabgrass and thicker grass coverage as the practical win. 79 percent of the reviews on this listing are five stars, which is a strong signal for a longer-blade design.
Who the EMBerg Monster XL Suits
Owners who see an uncut stripe down the middle of the lawn, or who mow weedy ground where a short blade struggles. Overlap plus inertia is the combination that fixes both problems, and it is the reason these blades rank so high despite the modest 18-piece count.
It also suits anyone who prefers to maintain rather than replace. Softer titanium steel can be filed back to an edge, so a set that would normally be binned can go back on the arm with ten minutes of work at the bench.
What to Watch Out For With This Pack
Check clearance before you fit them, since longer blades can put extra strain on the mower arm. This is the one swap in the roundup where you should not skip a dry fit and a hand check of the pivot range.
The included screws are shorter than OEM because the blade pivot shoulder is built in, and one reviewer found the edges do not hold a sharp edge as well as factory blades. Sharpening is easy, but the cut right after a fresh change may not beat an OEM set until the blade beds in.
11. Sunseeker Blades for V3, S4, X7, and X3 Plus: Model-Specific Fit
Sunseeker Blades for V3/S4/X7/X3 Plus Robot Lawn Mower
Alloy and stainless steel
Part SK-L-BLADES
12 blades plus 12 screws
2 Year Support warranty
Pros
- Custom fit for Sunseeker V3 S4 L22 X7 X3 Plus
- Blades stay sharp longer than OEM
- 12 blades plus 12 screws included
- Straightforward swap
- Manufacturer support included
Cons
- Highest cost per blade in this category
- Many reviews critique the mower software not the blades
- Satellite calibration and boundary issues dominate feedback
If you run a Sunseeker V3, S4, L22, Orion X7, or X3 Plus, this is the blade set made for it, part SK-L-BLADES in alloy and stainless steel. Twelve blades and twelve screws cover several replacement cycles, and the swap follows the original installation method with nothing special required.
The blade-specific feedback is positive on sharpness and fit, with owners reporting the edges stay sharper longer than the factory set at this level of spend. There is a two-year support warranty from the manufacturer, which is unusual in a consumable category.
We place it eleventh on value rather than function. The per-blade cost is the highest in this roundup by a wide margin, and much of the review volume is actually about the mower itself, with repeated complaints about satellite calibration failures and the robot leaving its boundary.
The listing is also inconsistent, with a stated 14 inch cutting width and package dimensions that clearly describe the mower rather than a blade kit. If you are deciding on value alone, a 30 or 36-piece aftermarket pack costs less per cut, but for a Sunseeker owner with no alternative listing this is the safe route.
Who the Sunseeker Blades Suit
Sunseeker owners, and only Sunseeker owners. The V3, S4, L22, Orion X7, and X3 Plus share this blade, and none of the generic multi-brand packs in this roundup is specified for those machines.
The two-year manufacturer support is a genuine benefit on a niche model. If a blade chips or the fit is wrong, you have someone to contact, which is worth more than the per-blade saving on a machine with a small owner base.
What to Watch Out For With This Pack
The per-blade cost is the clear drawback, and one buyer explicitly judged the pricing poor value against generic packs. If you ever switch to a different brand of robot, none of this carries over.
Read the blade-specific reviews carefully rather than the overall rating, because much of the volume is about the mower’s navigation software rather than the steel. On the blade question itself, feedback is consistently positive on fit and sharpness retention.

WUWENKK 40Pcs Replacement Blades Compatible for Mammotion Luba & Yuka All Series, Robust Titanium Replacement Robotic Lawnmower Blades, with Plastic Washers and Screwdrivers
HRC 60 coated 440C stainless
Twin-hole four-edge design
40 blades, washers, 2 drivers
3.4 x 2.3 x 1.2 inches
Pros
- Four cutting edges per blade
- Twin-hole design extends usable life
- Complete kit with 40 washers and two drivers
- Reported to hold past 50 mowing hours on Luba 2 AWD
- Higher stated edge hardness than rivals
Cons
- Thinner and shorter than OEM leaving an uncut centre strip
- Bends easily on uneven or rocky ground
- Thin washers that some buyers skip
- Included screwdrivers fit poorly
The most complete kit in the roundup: 40 blades, 40 screws, 40 nylon washers, and two screwdrivers in one box. For an owner who wants the whole consumable supply solved at once, nothing else here bundles this much hardware.
The spec sheet is the most technical we saw. The edges are 440C stainless steel with a titanium-carbide coating at a stated HRC 60 hardness, and the twin-hole patent-pending design gives four cutting edges per blade by allowing both flipping and rotation. The listing also cites ASTM F2944 fitment testing and an EN ISO 10816 vibration rating.
Owners on flat, well-kept lawns like the kit and report blades holding up past 50 hours of mowing time on a Luba 2 AWD. The screws come with threadlocker pre-applied, which is the detail that solves the loosening problem several other sets in this list create.
That pre-applied threadlocker deserves more attention than it gets. Across this roundup the most common mechanical complaint is a screw backing out mid-session, and this is the only kit where the manufacturer or seller has addressed it at the point of manufacture.
Who the WUWENKK Kit Suits
Mammotion Luba and Yuka owners on flat, well-kept ground who want everything supplied at once. Forty blades, forty screws, forty washers, and drivers in one box removes the last excuse for letting a worn blade stay on past the season.
It suits owners who mow frequently enough to hit the 50-hour mark on one set, and anyone who wants four usable edges per blade rather than two. On a lawn with no rocks and no hidden debris, that geometry adds up over a year.
What to Watch Out For With This Kit
Terrain is the limitation. Reviewers with uneven or rocky lawns report blades bending easily, and several note the blades are thinner and shorter than OEM, which leaves an uncut strip down the middle. If your property is not flat, pick the thicker option in pick two instead.
The included washers are much thinner than OEM and some buyers skip them entirely, and the bundled screwdrivers fit the screws poorly, so bring a standard number two Phillips. The titanium coating can also wear off quickly on coarse grass, which is a real limit on the HRC 60 claim.
How Often Should You Replace Robot Mower Blades?
Replace standard carbon steel blades every six to eight weeks, titanium-coated blades every four to six months, and heavy-duty or tungsten carbide blades roughly once a year. The real test is not the calendar but the tips of your grass: ragged, whitened, or browning ends mean the blades have gone dull, and a dull blade tears tissue instead of shearing it.
That interval assumes regular mowing and a reasonably clean lawn. A yard full of pine needles, sticks, and dandelions will chew through a blade set far faster, and a rocky or uneven property wears the edge down even quicker.
Signs your blades are done
Ragged, frayed, or whitened grass tips across the lawn
Faint brown or gray stripes where the mower cuts
Visible nicks, chips, or rounded corners on the cutting edge
Blades that no longer swing freely on the pivot arm
Mowing sessions taking noticeably longer to finish
On the last two points, owners on r/SegwayNavimow raise a fair objection: dull blades still mow the grass, and one user reports seeing no difference in the cut after a full year on the same blades. That is a real observation on short grass. What is harder to see is the accumulated damage to the leaf tissue, which shows up weeks later as browning and disease pressure.
Our rule of thumb is to flip two-sided blades when the first edge goes, and judge again after a full season. If the lawn looks healthy and stripes are absent, you are not wasting blades by stretching the interval.
Razor, Solid, or Mowing Disc: Which Blade Does Your Mower Use?
A razor blade is a small four-sided blade on a pivoting arm that swings sideways when it hits an obstacle, which is why it survives sticks and stones. A solid blade is a single fixed piece of steel, sharper per cut and sharpenable, but it will bend or snap on a hard impact. A mowing disc is a rotating plate used on some newer models, and it is a different consumable entirely.
Razor blades dominate because the pivot is a safety feature. A fixed blade cuts a cleaner line on very short, even turf, and owners on r/MammotionTechnology weigh exactly that trade-off, noting that fixed blades cut better but can cause damage, while movable blades deflect away from obstacles.
If your mower shipped with a disc and you want real blades, that upgrade is a genuine open question. The same question is asked repeatedly on r/mammotion, where owners compare their discs to the blades used on older Robomow and Ambrogio machines. Check your model’s manual before ordering, because the disc mount rarely accepts blades without modification.
Which Blades Fit Which Mower? Compatibility Checklist
No, robot mower blades are not universal across brands. The answer to whether all mower blades fit all mowers is a straightforward no: the pivot post diameter, screw thread, centre hole spacing, and blade length all differ between brands, and a blade that physically bolts on can still cut badly if the hole spacing is wrong.
Use this checklist to match your machine:
Husqvarna Automower – OEM Endurance pack, or the EMBerg and FourShow aftermarket sets. The two-sided 43 mm EMBerg Monster XL blades give the widest overlap.
Worx Landroid WG794 – the WORX WA0190 kit is the factory part, with other Landroid models using different sizes.
Segway Navimow – check your series letter. The i105N, i108N, i110N, H500N, H800N, H1500N, and H3000N share a compatible pack, but Roborock units are a separate fit.
Mammotion Luba and Yuka – the Luba Mini disc uses seven fixing positions instead of six, and the AWD 3000 takes thinner and longer screws than stock.
Gardena – shares the Automower blade footprint on many models, so both the OEM-equivalent and the multi-brand aftermarket packs fit.
ECOVACS GOAT – the O1000 RTK, A2500 RTK, and A3000 LiDAR use the factory GBK120001 kit and nothing generic.
Greenworks, Mova, Parkside, Robomow, McCulloch – McCulloch shares the Automower footprint. Greenworks, Mova, and Robomow use their own geometry, so match the model number before buying in bulk.
If you are still choosing a machine, our picks for the best robotic lawn mowers for backyards and the best robotic lawn mowers UK roundups both note blade availability, since a machine with a discontinued blade is a long-term cost. Owners shopping on steep ground can also compare our picks for the best robotic lawn mowers for slopes.
What Blade Material and Coating Should You Buy?
Carbon steel is the OEM default and gives a hard, sharp edge that rusts fastest. Stainless steel resists corrosion without losing much edge quality. Titanium-coated steel adds a hard surface layer that slows wear and flash rust. Tungsten carbide holds an edge far longer than any of these, but it is essentially unavailable at retail and mostly surfaces through enthusiast group orders rather than normal listings.
Are replacement blades already sharpened? Yes, they arrive sharp. The only real exception is a cutting disc, which is a plate rather than an edge. That also means a blunt blade is a replacement, not a repair, unless the material is soft enough to file, which titanium-coated and stainless blades are and hardened OEM carbon steel often is not.
One persistent claim deserves a warning. Owners on r/MammotionTechnology have seen tungsten carbide blades promoted on the basis that they would last ten times longer, sourced from chatbot answers rather than a retailer. We could not find a genuine retail listing in this category, so treat any tungsten carbide offer as unverified until you have seen the steel in person.
OEM vs Aftermarket: Is a Cheaper Blade Worth It?
Usually yes, provided the fit is right. The factory part guarantees the pivot post, screw thread, and hole spacing match, and it removes the single most common failure, which is a blade that fits but does not pivot freely. Aftermarket titanium-coated sets deliver comparable cutting quality for a fraction of the per-change cost when they are specified to your brand.
One owner on r/automower reports using both genuine and budget aftermarket blades and replacing them about once a year either way, seeing no meaningful cut difference. Another bought a large bulk pack and now swaps monthly. Both are reasonable, and the gap between them is far smaller than the price gap suggests.
Where aftermarket consistently wins is on hardware quality. Several kits in this roundup ship screws that strip or back out, while others ship galvanized screws with threadlocker already applied. That single detail matters more over a season than the steel grade, which is why we treat it as a tiebreaker throughout this list.
The real cost of a cheap blade is not the blade, it is the failed swap. Check whether the pack includes screws and washers, and whether the blade is described as pivoting, before you order.
How to Replace Robot Mower Blades in Five Steps
First, park the mower on a flat surface, turn it off, and remove the battery if the model has a removable one. Most manufacturers expect this before any underside work, and the Landroid kit even includes the battery removal step in its own instructions.
Second, flip the mower over onto a soft surface and photograph the existing blade layout before touching anything. If you are running one blade per arm, note the orientation, because reversing a blade flips the cutting direction and changes the cut.
Third, back the screws out slowly and treat the threads with penetrating oil first. The most common complaint across every kit we reviewed is screws that will not come out, and a stripped screw head turns a two-minute job into a trip to the hardware store.
Fourth, fit the new blades and hand-check that each one swings freely and all the way around on its pivot post with no binding. This is the safety check most people skip, and it is also the fastest way to catch a wrong-size blade before it meets a stick.
Finally, add a drop of threadlocker to each new screw before tightening. Yes, the screws should be replaced along with the blades, and threadlocker is what stops a blade backing out mid-session, which explains the loosening complaints on several aftermarket kits above. Reuse your old washers if the new pack did not include them.
Frequently Asked Questions
How often should I replace robot lawnmower blades?
Replace standard carbon steel blades every six to eight weeks, titanium-coated blades every four to six months, and heavy-duty or tungsten carbide blades about once a year. Debris-heavy or rocky lawns wear blades much faster. Judge by condition rather than date: ragged whitened tips, browning stripes, visible chips, or a blade that no longer pivots freely all mean it is time to change.
Do all mower blades fit all mowers?
No. Robot mower blades vary between brands in pivot post diameter, screw thread, centre hole spacing, and blade length. A blade can physically bolt on and still cut badly if the spacing is wrong. Match the model number before buying, and note that some models use unique disc mounts or differing screw sizes.
Are replacement lawn mower blades already sharpened?
Yes, robot mower blades normally arrive with a factory edge and are a replace-not-repair consumable. Softer titanium-coated and stainless blades can be restored with a file, while hardened OEM carbon steel usually cannot. Cutting discs are the exception, since they are a rotating plate rather than a sharpened edge.
What are the best replacement mower blades?
The Husqvarna Endurance pack is the safest all-round choice for Automower owners. For Mammotion Luba and Yuka the FourShow 36-pack offers the best value at 0.9 mm thickness, and the Headley Tools 30-pack covers the widest range of brands in one bag. Match the pack to your brand and blade style before anything else.
Should I replace the screws when I change robot mower blades?
Yes. The mounting screws are cheap and strip or corrode over time, and a loose screw lets a blade back out mid-session. Add a drop of threadlocker to each new screw before tightening, and soak rusted screws with penetrating oil before removal so you do not strip the head.
Should I run one blade or two per arm?
One blade per arm is the factory setup and keeps the arm balanced. Running two increases cutting capacity on thick turf such as Bermuda, and some Landroid owners add washers and double up to compensate for wear. More blades add drag and vibration, so verify clearance and balance before committing.
Our Verdict on the Best Replacement Blades for Robotic Mowers
The Husqvarna Endurance pack is our pick for 2026. It holds the highest rating and the largest review base of the 12 we compared, and the factory part removes every fitment question on a machine you just spent real money on.
Owners of other brands should match the pick to their model rather than forcing a generic blade. Mammotion and Segway Navimow owners have strong 36-piece titanium sets, Landroid owners have a proper flippable OEM kit, and ECOVACS GOAT owners have no alternative to the factory one anyway.
Two habits matter more than the pack you buy. Check that every blade swings freely before you power the machine back up, and put threadlocker on the new screws. Check the current price and pack details for your exact model, then keep a spare set on hand rather than waiting for a blade to fail mid-cut.
