Batteries and lawn ratings are the difference on a shared compact AWD platform.
This one comes down to rated area and battery first, then to the limits of your own setup.

Both products are checked against the same needs. The first verified differences still standing are named here.
7 of the 56 robotic lawn mowers checked handle both “The area I can mow is less than a quarter acre” and “Long steep slopes run across the lawn”. Both make the cut.

Plug in your numbers
This checks hard limits only. Personal preferences are left out of the math.
Its rating covers 0.15 acre and 45% grades inside the boundary, with no wire to lay. You entered 0.25 acre and a 20% grade.
Its rating covers 0.25 acre and 45% grades inside the boundary, with no wire to lay. You entered 0.25 acre and a 20% grade.
The area check uses the published maximum with no reserve added. When a systematic mowing rating is shown, the mower has to follow that pattern to reach the maximum area. Slopes at the boundary can have a lower limit than the interior. You still need to check trees, gates and separate zones.
