Every lawn mower, scored against your actual lawn.

Scoring note

Reliability 7.0 (30%): multi-month hands-off owner reports are real, but so are the recurring drop-off, stuck-on-flat-ground and firmware-map-drift themes. Performance 8.0 (25%): accurate navigation and clean lines, held back by slow passes, weak handling of leaves and twigs, and a hard dependency on sky view. Usability 8.5 (20%): the standout — no wire, app-driven mapping, though antenna siting is guesswork until the dock is placed. Value 8.5 (15%): $1,299 MSRP is at the cheap end of wire-free RTK, though the Sunseeker X3 Plus, Worx Vision Cloud and Luba mini AWD 800H all list lower. Support 7.5 (10%): OTA updates and a growing lineup, but a short track record and no warranty length we could verify. Weighted total 7.8 (7.825).

Known issueRepeated getting-stuck reports on flat lawn, persisting after owners fitted off-road wheels; drop-off detection at curbs is weak Home Depot reviews
Take it home ifYour lawn is under a quarter acre and mostly open to the sky, and you want wire-free setup without paying premium-tier prices.
Walk past it ifYour yard is heavily shaded or hemmed in by tall buildings, or you have unfenced curbs, retaining walls or a raised deck edge.
Editor's note

All three land at 7.8 and the rubric will not separate them, so here is our call. The Automower 430X is $2,499 MSRP before you bury a wire, and it has left Husqvarna's US lineup, so you are buying dealer stock. The Honda HRN216VKA is a gas machine Honda stopped building in 2023; what is on the shelf is what is left. For the open quarter-acre most readers have, the Navimow i110N is the one to buy: no wire, an afternoon of setup, and the cheapest credible RTK on the list. Shaded or walled yard? Ignore the tie and read the 430X.

It cuts like a gas mower and the rear-wheel self-propel is genuinely good, but plan on a second 4Ah battery for anything past a quarter acre and treat the plastic drive gears gently.

How we score

Manufacturer ratings, not our measurements.
30%Reliability25%Performance20%Usability15%Value10%Support & ecosystem

Reliability · 30%

Does it keep working after year one? We weight recurring failure themes from long-term owner reports on Reddit, forums, and multi-month videos above anything a launch-week review can measure.

Performance · 25%

Does it do the core job well? Manufacturer specs are checked against category norms and validated against owner-reported and long-term reviewer results.

Usability · 20%

Setup, app quality, daily friction. App-store rating trends, setup complaints, and support-ticket themes all count.

Value · 15%

Price versus what the tier actually delivers. Running costs — filters, blades, subscriptions — count too, not just sticker price.

Support & ecosystem · 10%

Warranty length, parts availability, firmware update cadence, and how the brand responds when things go wrong.
