Navimow i206 AWD

Rated for 0.15 acres and 45% grade — that is 24.2°, not 45°. On a real lawn, once you allow for borders and travel paths, plan on about 0.12 acres.

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.

If your ground is steeper

These are rated for a similar area but hold more grade than the Navimow i206 AWD’s 45%.

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.
