DREAME
A3 AWD Pro 5000
Rated for 1.2 acres and 80% grade — that is 38.7°, not 80°. On a real lawn, once you allow for borders and travel paths, plan on about 0.96 acres.
What it handles
All four wheels drive, which is what buys the steeper rating. That puts it in the small group that can work genuinely steep ground.
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 A3 AWD Pro 5000’s 80%.
Cross-shopped with
Rated for a similar area, at the same grade or less.
How confident we are
Cross-checked against the manufacturer and at least one other source.
Area corrected from 1.25 to 1.20: Dreame publishes 1.20 acres for the 5000 variant. Exact conversion of 5000 sq m is 1.24, so Dreame rounds down - 1.25 matched neither. Dreame prints 38.7 deg for 80%; this table uses its own conversion throughout. Do not use the "1.24 Acre/Day" figure on dreametech.com - that is Rush-mode throughput, not rated area.
