A powerhouse of a robot lawn mower, the Mammotion Luba 2 AWD has an all-wheel drive system that lets it power over rough ground and climb steep slopes.

Boundary-free setup and smart navigation can make life easier, although I found it took a bit of fiddling to get everything set up. Once running, this robot provides an exceptional cut.
