Which robot vacuum maps better, the Dreame L10 Pro or the Ecovacs X1?

The Dreame L10 Pro maps better by a small margin. Both use lidar, but Dreame’s mapping is more consistent — fewer phantom walls, less drift, and it handles multi-floor homes better without resetting. The Ecovacs X1 has a flashier app with video camera and voice control, but its core mapping accuracy has more hiccups. If clean, reliable floor plans are your priority, the Dreame wins.
