When u start mapping for the fisrt time u need to tiddy the floors so it can map clearly.this is very important in future and will help it to go all the corners and then if there is obsticle it will avoid it.
Hi Do you need to lift up doormats etc when mapping? Or does it sense tile to carpet change? And can you map 2 floors? And does the robot return to base to charge if you have a large floor space to clean
