A robot lawn mower cuts your grass on a schedule and heads back to charge on its own, so you get your weekends back. Every model here works without a buried boundary wire. We’ve lined up seven current US models on the specs their makers publish, so you can match one to the size and slope of your yard.

Slope ratings are each maker’s own figure. A 45% slope rises 4.5 ft over 10 ft of ground. If part of your yard is steeper than a mower’s rating, plan to keep it out of that zone.
The seven mowers
Mammotion LUBA 3 AWD 3000
The LUBA 3 finds its way with a 360° LiDAR, network RTK and AI cameras together. The listing says it recognizes more than 300 obstacle types and steps over objects up to about 2 in. You also get two 165W cutting motors, a cutting height from 1.0 to 2.7 in and up to 175 minutes per charge.
Suits: large, sloped or complicated yards up to 0.75 acre with lots of separate areas.
Worth knowing: it’s rated for the biggest lawn in this guide, so on a small, flat lawn you’d be paying for capability you won’t use.

Mammotion LUBA mini 2 AWD 1500H
The LUBA mini 2 brings LiDAR, dual cameras and all-wheel drive to a smaller mower rated for 0.37 acre and 80% slopes. It has a separate edge-cutting disc, and its DropMow mode lets it start mowing without mapping the yard first.
Suits: mid-size, hilly yards where tidy edges matter.
Worth knowing: it handles up to 20 zones, fewer than the LUBA 3’s 30. That only matters if your yard is very broken up.

DREAME A3 AWD 1000
The A3 uses LiDAR and two cameras, is rated for 80% slopes and climbs over obstacles up to 2.17 in. It cuts to within 1.97 in of edges, recharges in 45 minutes with the 5A adapter, and carries a 4G module and HDR camera for security.
Suits: sloped yards, especially if fast recharging and anti-theft features appeal.
Worth knowing: the listing gives coverage as 0.25 to 0.50 acre without saying which figure applies to this 1000 model. If your yard is near the top of that range, check with the seller first.
WORX Vision Cloud WR341
The WR341 gets its RTK positioning from the cloud, so there’s no antenna to put up, and it uses vision in shaded spots. Four-wheel drive is rated for slopes up to 84%, the steepest rating in this guide, and a Cut-to-Zero offset blade gets close to edges.
Suits: steep yards up to 1/4 acre where you want the simplest setup.
Worth knowing: it’s rated for 1/4 acre, so bigger yards need a different mower.
Segway Navimow i210 AWD
The i210 uses network RTK plus vision and maps your yard with one tap. It covers up to 0.25 acre, handles 45% slopes with all-wheel drive, and cuts 7.1 in wide at 2 to 3.6 in tall. Its 5.1Ah battery covers up to 2,690 sq ft per charge.
Suits: gently sloped quarter-acre yards, and people who like their grass a bit longer.
Worth knowing: 45% is the lowest published slope rating in this guide, so skip it if you have a steep bank.
Segway Navimow i105N
The i105N is made for small lawns up to 1/8 acre. It pairs RTK with a 140° camera, recognizes more than 150 object types, runs at a stated 58dB(A), and the listing states a 3-year warranty.
Suits: small, simple yards.
Worth knowing: it’s rated for the smallest area in this group, and the listing doesn’t give a slope rating.
eufy E15 Gen2
The E15 Gen2 finds its way with cameras alone, so there’s no RTK station to place and no wire to bury. It maps as it mows, handles zones up to 60m apart, recognizes 500+ obstacle types and adds GPS plus 4G anti-theft tracking with a remote camera view.
Suits: people who want the quickest possible setup.
Worth knowing: the listing doesn’t state a lawn size or slope rating, so it’s hard to compare with the others on those.
How to choose
- Measure your lawn. Pick a mower rated above the area you actually mow, not your whole lot.
- Check the slope. Steep banks call for all-wheel drive and a rating above your steepest patch.
- Think about signal. RTK works best with a clear view of the sky. Under heavy tree cover, vision or LiDAR helps.
- Count your areas. Front yard, back yard and side strips each count as a zone.
- Setup. The WORX WR341 needs no antenna, and the eufy E15 Gen2 needs no station.
Questions
Do any of these need a boundary wire?
No. Every mower in this guide works without a buried perimeter wire, according to its listing.
Which handles the steepest slope?
The WORX Vision Cloud WR341, rated for up to 84%. The two Mammotion models and the DREAME A3 are rated for 80%.
What is RTK?
RTK is satellite positioning corrected by a reference signal, which lets a mower know where it is to within a few centimeters. Some models use a base antenna in your yard, while the WORX WR341 and the network RTK models get that signal online.
When should I buy a robot mower?
Before your mowing season starts, so you have time to map the yard and set up zones.
