Well, unfortunately, I must add my voice to the disappointed here. The cleaning performance after Chaosprizip was actually pretty good. In two starts were daily kitchen UDN living room (50 square meters) almost always amazingly clean. There was almost no failures - a time he was stuck on a slant, once he found the basis of non - for 60 runs which is not much. But then he went on strike more frequently with blocked wheels or suction rolls. However, even after protracted removing the entire hair is brushed our daughter he strike more frequently and had to be returned eventually. Then the disappointment: Unable to repair. Well, at least there's the money. Too bad!
