A robot vacuum for multiple floors can remember more than one layout, but saved maps do not move the robot, its dock, clean water, or dirty debris between levels. The practical choice is usually between carrying one robot, automating one main level and cleaning the other manually, or placing a robot on each frequently cleaned
A robot vacuum map is useful when it becomes a control layer, not just a picture of the floor plan. Saved rooms, zones, no-go boundaries, no-mop areas, and routines can reduce repeated setup, but they do not prove that the robot can recognize every cord, toy, or small obstacle. The practical buying question is whether
LiDAR and camera systems solve overlapping but different problems in a robot vacuum, so the sensor name alone does not tell you how well the machine will navigate or avoid clutter. LiDAR is especially useful for distance-based mapping and localization, while cameras can add visual information that helps some systems recognize objects, but implementation matters
