iRobot Roomba

The Roomba line, including the j9+ and Combo 10 Max, handles multi-floor homes through automatic floor-plan switching. Your app stores up to 10 separate maps, and the robot remembers which one to use when placed on each level. This eliminates the manual setup usually needed when moving between floors.

The self-empty base holds several weeks of debris, so you won't need to empty the bin after every run. That convenience matters on larger homes where frequent trips to the garbage can add up.
