Mammotion LUBA

Highest slope ratings in the consumer market. RTK GPS wire-free with AWD — LUBA 2 (65%) and LUBA 3 (80%). Built for steep terrain.

Mammotion is the slope leader. The LUBA 2 AWD handles 65% gradient and the LUBA 3 AWD pushes to 80% — numbers no competitor matches in the consumer tier. Both use RTK GPS for wire-free virtual boundaries, so there's no buried cable to maintain on steep terrain.

They're newer than Husqvarna, and there's no dealer network to call on — support goes through the app. But for property owners with serious slopes, the torque and gradient ratings justify the trade-off. See the full picture in our lawn size buying guide.
