I have read probably not neat, because he has appeared in my search and I've wanted to clearly battery. After the first shock was over, I got to grips screwed together and am sometimes driven over the vollgekrümeltem with cat litter floor and lo and behold, he creates. The mechanics of the brush really works. Well, he is a bit hard, and he has not a pivotable joint, so straight on hip, but he is supposed only in between replace the vacuum cleaner and for that he is really okay. It already saves power and he is always ready.
