Best robot mowers for slopes
Slope rating is the spec that separates robots on hilly ground — exceed it and the mower slips or stalls. These models publish a slope rating, ranked steepest first.
How we rank: robots with a sourced slope rating, ranked by maximum gradient (steepest first). These are transparent sorts on sourced specs — we don't publish editorial scores until they're defensibly sourced. Blanks mean "not specified", never a guess.

FAQ
What does a slope percentage mean?
It's the gradient as a percentage: a 45% slope rises 45 cm over each metre travelled. All-wheel-drive models reach the highest figures.
