A. Roomba s9+ builds a map of the area each time it starts a new cleaning job. After cleaning the same space a few times, the robot produces a Smart Map that you can customise in the iRobot Home App. You can merge, split and label rooms as you see fit. After that, you can even set a schedule so that the Roomba s Series cleans certain rooms on specific days at certain times or an entire level of your home on the days you choose.
