Robot mowers for steep slopes
Slope is the specification that rules out the most models, and the one buyers most often misread. Every mower here publishes a rating of 35% or more.
24 mowers match, as of 2 October 2026.
How this list is built

If your slope is steeper than any of these
Every mower listed above publishes a rating of 35% or more, which is where manufacturers start marketing a model as slope-capable. The very best all-wheel-drive machines reach roughly 55%.
Above that, the honest answer is that no robot mower on the market is rated for your bank. That is a limit of physics and safety, not of software, and no firmware update will change it.
If that is your situation, you have three realistic options: exclude the steep section from mowing and cut it another way, replant it as a bed or ground cover, or move to a remote-control mower — a different category of machine that you operate yourself rather than leaving to work alone.
