While I am writing this, my new little leaves quitschend and humming through the apartment. 3 rooms. Living room (carpet), hallway and bathroom are free for him. What should I write? Fantastic! He really gets clean everything. Except for the, well, admittedly, corners. But since he can not go so well because he's around. Despite his Saugerei is quite amazing. After sucking brush control, empty the dust container, that's it. By the way, until now he has always found "home". On cabinets, walls, stairs etc drives my approach very carefully and then nudges. Speaker cables, no problem, he stumbles over it and then puts the car into reverse. Only my bathroom stool he moves, probably so that it can also suck there. ;-) Aloud he is, however, not as loud as a "real" vacuum cleaner, but it bothers already. It is better to leave the apartment after you are sure that he can get stuck nowhere. Will recommend the little ones ...
