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?

Many 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. Some newer models replace it with a correction service instead — the next question.

Is the maker's network correction service available at your lawn?

Some wire-free mowers replace the property antenna with a positioning-correction service delivered over the mobile network. This is not the same as ordinary phone reception — the manufacturer has to cover your address. Check the model's coverage map if you are not sure.
