The GOAT G1 finds itself by triangulating off the UWB beacons, so it needs to "see" at least two beacons at any spot. Ecovacs requires ≥80% of the map covered by 2+ beacons and ≤10% with no coverage at all. Covering an area with a single beacon is not enough — that's the main thing this tool optimizes for, and the thing most DIY placements get wrong.
Tall obstacles (>60 cm) block the radio signal. The heatmap and validator both account for obstacles sitting between a beacon and a patch of lawn, and between beacons themselves.
