GOAT A3000 LiDAR Pro
Rated for 0.75 acres and 50% grade — that is 26.6°, not 50°. On a real lawn, once you allow for borders and travel paths, plan on about 0.6 acres.
What it handles
Two-wheel drive, which caps how steep it can work. 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.
If your ground is steeper
These are rated for a similar area but hold more grade than the GOAT A3000 LiDAR Pro’s 50%.
How confident we are
Cross-checked against the manufacturer and at least one other source.
Slope filled from the ECOVACS US spec table: 50%. Charge-time conflict resolved - 70 min is the PRO (7500 mAh); the 45 min figure belongs to the non-PRO A3000 LiDAR (5000 mAh). The PRO product page carries no acreage row; 0.75 ac comes from the ECOVACS press release and retail listings.
