What it handles

All four wheels drive, which is what buys the steeper rating. That covers rolling ground, but not a bank you would struggle to walk up.

Navigation includes vision or LiDAR, so it keeps working under tree cover where satellite-only machines lose their fix.

Below a quarter acre once the coverage buffer is applied — too small for any of our acreage bands.

How confident we are

Cross-checked against the manufacturer and at least one other source.

Confirmed on navimow.com: 0.15 acre, 45% (Segway prints 24 deg). Marketing "up to 0.18 acres" is a stretch figure, not the rating. Lowes understates it as 1/8 acre.
