Robot Mower Fit

Mower selector

Describe the yard. We eliminate the models that cannot handle it, and tell you exactly which of your constraints we could not verify.

Your lawn
sq ft

Roughly the mowable area, not the lot size. A quarter acre is about 10,900 sq ft. Leave blank to skip this check.

%

Percent, not degrees: a slope that rises 1 ft over 4 ft is 25%. Leave blank if you are not sure.

%

Worth measuring separately. Several manufacturers rate the boundary far lower than the middle of the lawn — as little as 10% — and that is usually what actually rules a mower out.

Installation
Are you willing to bury a perimeter wire?
Can you mount an RTK antenna or reference station?

Most wire-free mowers need a small antenna on a pole or wall with a clear view of the sky, wired back to the charging dock.

How many separate areas need mowing?
