A situation

Which Robot Lawn Mower Fits Your Lawn’s Size and Slope?

Lawn size and slope are the two limits a maker rates. These four state both, and differ in how much of it anyone outside the maker has tested.

A back-garden grass bank seen side-on: the Roborock RockMow X120H climbs the steep middle of the bank while the Husqvarna Automower 410 iQ mows up the gentle foot, a board fence stepping up the curve behind them.

Crossed slopes, dips and uneven patches without wheel-spinning. Another tester saw brief struggle on dry, steep ground. Grade not stated.

Figures were read from each maker's product page between 9 and 11 Oct 2026, and launch coverage was used only for price and US availability. A slope test was searched for each exact model; Not found means nothing turned up, never that none exists.
