Robot Lawn Mowers

Wire-free robot mowers from Sunseeker, Yarbo and Lymow — matched to your slopes and acreage.

Robot lawn mowers for yards that are not flat, manicured squares. Every model here mows without a perimeter wire. Most place themselves by RTK satellite positioning fused with camera vision; the Sunseeker X4 takes a different route, navigating by 360° 3D LiDAR with Vision AI, so it needs no RTK antenna and no clear view of the sky.

The range splits by drive. The Yarbo and the Lymow One Plus run on rubber tracks, which spread the load across a wider contact patch — more grip on wet grass and slopes, and less rutting on soft ground. The Sunseeker models run on wheels: four-wheel drive on the X9 Plus, all-wheel drive on the X7 Gen 2, rear-wheel drive on the X4. Rated slopes, per each manufacturer: Lymow One Plus 100% (45°), Sunseeker X9 Plus 90% (42°), Yarbo and Sunseeker X7 Gen 2 70% (35°), Sunseeker X4 45% (24°).

Choosing a robotic lawn mower for your yard

Three things decide the right model: how much ground you need cut in a day, how steep the worst part of your lawn is, and what the mower has to drive over to get around — roots, curbs, drainage channels and garden edging all matter more than total acreage does.

If you are unsure which model suits your property, send us a rough acreage and a description of the slopes and obstacles and we will tell you honestly whether a robot mower is the right answer for it.

Where to start

Choose by terrain

Three builders, one rule: nothing here needs a boundary wire. Lymow and Yarbo run tracks, Sunseeker runs wheels, and the range covers a third of an acre to six.

01

Terrain that stops most robots

Rubber tracks on a cast aluminum chassis — grip for the slopes and soft ground that leave lighter machines spinning.

Tracked drive · cast chassis 02

Six acres, edges included

The largest single machine in the range — four-wheel drive to a 90% grade, and an EdgeZero arm that trims what the deck cannot reach.

Sunseeker X9 Plus · 6 acres 03

One body, four seasons

Yarbo’s Core swaps between mower decks, a snow blower, a leaf blower and a trimmer — the mower is one module of a year-round machine.

Outdoor Robots · The yard, off your schedule

The lawn, unmanned

Coverage figures come from each builder’s own testing — 1.1 to 1.73 acres a day from Lymow, up to 6.2 acres maintained twice a week on Yarbo’s Pro deck, and 0.3 to 6 acres across the Sunseeker range. They answer slightly different questions, so read the guide before comparing them. If your yard has slopes, heavy tree cover or an unusual shape, tell us about it before you choose.
