Automower 450XH EPOS
Rated for 2.5 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 2 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 is satellite-based without vision or LiDAR, so heavy tree cover is a real risk — it loses its fix under canopy.

How confident we are
From a single source. We are still verifying it.
AREA CONTESTED. The old 1.5 acres matched no source at all. Husqvarna US spec table says Lawn Size 2.5 acres with "area capacity - irregular" 1.25; the operator manual says 5000 sq m / 1.25. Using 2.5 for consistency with the 420iQ, whose 1.0 comes from the same Lawn Size row - but Husqvarna contradicts itself here. Slope 45 percent, 15% at boundary. May be leaving the US lineup.
