It scans the entire flat when you first start it and saves the data. You then have your entire flat saved as a map on the app and can also clean individual rooms.

You can also start the robot manually and it will clean the rooms perfectly. Not everything has to be done via the app. Therefore, it also works with several rooms.
It can save four floors / cards. However, it is important to note that it only works with the Roborock S6 app, it does not work with the Xiaomi app.
I believe that if you help the robot to create the maps via the thresholds, it will probably save them in a map anyway. It recognises that there is a room behind the threshold. Then you can put it in the room later and it usually finds its way around quickly. But I think it would be easier to start it manually.

This is exactly the question I am interested in, as it could only register 1 room at a time because of the thresholds. Can you simply lift it and put it in the next room and the flat is still completely recorded? Or do you have to create several maps/floors for this? And are they limited to 3, if I read that correctly?
