Dreame X50 Ultra Complete Black

Coolblue review by Arvid (original Dutch). Setup is a lot of work; basically only usable in an empty room. Furniture confuses it unless chairs are placed to the centimeter. Camera does not read chair legs, climbs over things unnecessarily, invents new pieces on the 3D map, cleans poorly, and throws new faults every night. Called an absolute misbuy.

Coolblue 4.8/10 review by Martijn (title: "Robot met onafgewerkte software"; original Dutch). Bought after a Roborock Qrevo failed. Lidar fails to raise so the robot goes blind and gets lost; stares ~10 seconds before each action; skips edges/corners; reports ~20% battery after half a room which seems wrong. Happy with Coolblue service: returned it and bought a Roborock Saros 10R instead.

Coolblue review by Hans (original Dutch). Called it a bumper car that also does not know how to return to its base station. Spent about 4 hours on "mapping" that should take ~10 minutes and never even got to vacuuming. Fast delivery and good handling otherwise; Coolblue refunded. Does not dare try this vacuum again.
