Anthbot M9
For flat, tidy quarter-acre lawns on a budget, where it cuts neatly and quietly. Bumpy or overgrown yards will frustrate it.

4.4/5
For quarter-acre yards with steep slopes or heavy tree cover, where RTK mowers lose their fix. Its all-wheel drive and LiDAR cost more than an RTK model of the same size.

Pros
- Climbs 80% grades, so steep, hilly yards are fine
- LiDAR mapping keeps working under heavy tree cover and beside walls, with no RTK antenna to place
- Cutting height is set from the app, and each zone can have its own height
- Gets through 23.6 in gaps, so it can reach side yards
Cons
- Narrow 7.9 in cut makes a single pass slower than on wide-deck rivals
- Leaves a strip up to about 2 in along edges unless you buy the trimmer module
- Costs more than RTK-only mowers of the same size
- Runtime per charge isn’t published
