X7
Rated for 0.75 acres and 70% grade — that is 35°, not 70°. On a real lawn, once you allow for borders and travel paths, plan on about 0.6 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.
