1: What about curtains that end 2 cm above the floor? Does it recognise them as an obstacle or does it clean up to the window/wall. Irobots Roomba S9 and Braava M6 push them aside and clean up to the wall. How does it cope with bathrooms? 2.1: Problems with getting stuck under the toilet bowl? 2.2: Does it make it onto the bath mat/carpet, or does it push it around the bathroom or even get stuck? Thank you!
