I have two large empty rooms from a dancing school, which I am trying to clean with two roborock vacuums. The size is about 12m x 12m. With the Qrevo Edge, the mapping and navigation works flawlessly. The Qrevo Pro gets lost, when it is in the middle of the room and after some time the map gets a total mess. Often there appears a ghost image of the room itself in a random orientation in the map. It seems, the Qrevo Pro doesn't "see" orientation points when it is in the center and relocating completely fails.

Has anyone some information on the range of the Lidar sensor? Are there any significant differences between the models?
