Mowers for steep yards

Best for your yard The best robot mowers for steep hills and slopes in 2026 Wes Carmody Sep 2026 Three mowers rated for a steep lawn. We compare them on the maximum slope each brand gives, on lawn size, and on trees. Then we say which one to buy for your hill. Review 4.3/5 Mammotion LUBA mini 2 AWD review: a small, steep yard with trees over it Wes Carmody Nov 2026 It drives all four wheels, so it can climb a steep bank. A laser maps the yard, so trees overhead do not stop it. Check your grass first: this version cuts no shorter than 2.2 in. Review 4.0/5 Segway Navimow i210 AWD review: a sloped quarter acre, best with open sky Wes Carmody Oct 2026 Navimow rates this mower for a quarter acre, and we would plan on about 0.2 acre of sloped lawn. Navimow says the mower keeps its satellite signal under tall trees. Check how much open sky your lawn has. Review 4.3/5 Mammotion LUBA 3 AWD 3000 review: steep slopes, even under trees Wes Carmody Oct 2026 Most robot mowers cannot climb a steep slope. The ones that steer by satellite stop under trees. This one drives all four wheels up the hill, and a laser keeps it mowing in the shade. Head to head Navimow i215 LiDAR vs LUBA mini 2 AWD: which one climbs a steeper lawn? Dana Whitlock Nov 2026 Both use a laser to find their way, so both keep working under trees. Both are rated for the same size of lawn. Where they differ is how steep a hill each one can climb.
