All robot lawn mowers. Every figure below is placed against the whole class, so a gap can be read against how much the class itself varies.
Where each one suits you.
The conditions each robot was assessed against, side by side. Rows marked in gold are where these machines genuinely differ.
| Condition | Yarbo M20 | Automower 405VE NERA |
|---|---|---|
| Yard size | ||
| Under ¼ acre | GoodYarbo rates up to 1.5 acres a day, far more than a small lot needs. | GoodHusqvarna rates 900 m², close to a quarter acre, though no independent test was found. |
| ¼ – ½ acrethey differ | GoodLawns of this size sit well inside the 1.5 acres a day Yarbo rates. | DependsHusqvarna's 900 m² rating covers only the small end of a quarter to half acre. |
| Over ½ acrethey differ | DependsRated to 1.5 acres a day with recharging, but no delivered unit has been checked against it. | PoorLawns over half an acre are more than twice Husqvarna's 900 m² rating for this model. |
| Terrain | ||
| Mostly flat | GoodFlat lawns sit far inside the tracked chassis's 70% slope rating. | GoodHusqvarna designs its pattern mowing around open lawns, though no independent test was found. |
| Gentle slopesthey differ | GoodTracks and a rated 70% slope are built for rolling yards, per Yarbo. | DependsHusqvarna rates 30% slopes inside the lawn, but no independent slope test of the 405VE was found. |
| Steep / hillythey differ | DependsThe 70% slope rating is a maker claim that no independent test has checked before delivery. | PoorHusqvarna rates 30% inside and 20% at the boundary, below what steep lawns demand. |
| Grass type | ||
| Typical lawn grass | DependsCutting width is unpublished and sources disagree on the cutting height range. | DependsHusqvarna lists a 20-55 mm electric cut height, but no independent cut-quality test was found. |
| Mixed / tall growth | DependsThe cutting height ceiling is reported as about 4 in, but sources disagree on the low end. | DependsNo independent test of the 405VE in long or overgrown grass was found. |
| Thick (Bermuda / Zoysia) | DependsNo motor or blade details exist yet to judge dense turf. | DependsNo independent test in thick or dense turf was found for its 22 cm cut. |
| Boundary setup | ||
| Wireless required | GoodYarbo describes wire-free NetRTK positioning with no outdoor base station. | GoodEPOS virtual boundaries need no wire, with correction over cellular or Wi-Fi from Husqvarna Cloud. |
| Wire required | PoorYarbo says the M series uses no traditional boundary wires. | PoorHusqvarna lists virtual boundaries as the only boundary type, so there is no wired installation. |
| No preference | GoodWith no boundary preference, NetRTK setup needs no wire, taking about 30 minutes per Yarbo. | GoodIts wire-free setup meets a buyer with no boundary preference. |
A robot being poor for a condition is a fact about fit, not a fault. “Depends” means the record names a limit worth reading, not that the answer is unknown.
How far apart is a long way?
A number only means something next to the spread it sits in. Each track is the real range across every classified robot in the class, with the median marked.

Not compared, because fewer than two of these robots carry a published figure: Price, Charge time, Noise, Weight, Height.
What the numbers leave out.
Written on each record, and the only thing here every robot on the site carries.
The trade-off
What each design gives up to be good at what it is good at.
Yarbo M20
One tracked Core covers four seasonal jobs, and every module after the mower arrives on its own later schedule.
A 70% slope rating on tracks is the claim; no delivered unit has been tested against it.
Husqvarna Automower 405VE NERA
An infrared AI camera that works at night on a 900 m² mower, with no independent test yet of the 405VE itself.
Who each one is wrong for
Stated by the record itself. A robot being wrong for a household is a fact about fit, not a fault.
Yarbo M20
- Buyers who need a mower this season
- Backer deliveries have not begun; BackerGuardian reports mower bundles slipped to mid-September 2026 and snow blower bundles to mid-November.
- Buyers wanting a retail purchase with a store return policy
- The M20 has so far been sold only through Yarbo's Kickstarter campaign, with no retail listing found.
- Owners who need a published cutting width
- Yarbo has not published the M20's cutting width, and sources disagree on its cutting height range.
- Owners who want independent results first
- No outlet has described the final M20 mowing a lawn; coverage so far rests on Yarbo's campaign and IFA material.
Husqvarna Automower 405VE NERA
- Buyers who want independent test results first
- News outlets covered its launch, specs and pricing; no hands-on test of the 405VE was found.
- Steep lawns
- Husqvarna rates 30% slopes inside the installation and 20% at the boundary, below the 50% of the larger 430V and 450V.
- Lawns larger than 900 m²
- Husqvarna rates the 405VE for 900 m², and 600 m² in irregular mode; the 410VE covers 1,500 m².
- Buyers who want a wire boundary option
- Husqvarna's spec table lists virtual boundaries as the only boundary type for the 405VE NERA.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Yarbo M20
- Seasonally: Swap the mower module for the snow blower or leaf module as the season changes.
- As needed: Replace mowing blades once Yarbo publishes intervals for the M20 mower module.
- Monthly: Clear grass and debris from the tracks and the underside of the mower module.
- As needed: Wipe the AI vision camera lenses.
Husqvarna Automower 405VE NERA
- As needed: Replace the pivoting razor blades on the two cutting discs; 6 spares come in the box.
- As needed: Adjust work areas and temporary stay-out zones in the Automower Connect app.
- As needed: Install firmware over the air through the app.
- As needed: Keep the front camera clear so object detection can work.
- Seasonally: Update schedules and cutting heights as grass growth changes.
How much each of these is standing on.
Classifications rest on different depths of evidence. A pre-release assessment and a verified one are not the same kind of claim.
| Robot | Evidence status | Sources reviewed | Last assessed |
|---|---|---|---|
| Yarbo M20 | Pre-Release | 2 | Sep 2026 |
| Husqvarna Automower 405VE NERA | Verified | 7 | Sep 2026 |
Evidence status counts the sources behind a classification, not their kind. A high count can be maker documentation and price coverage, so read it as how much was reviewed rather than as independent testing. How we weigh evidence.
