My wife amused, but it does have a practical use. For sucking in between this fulfills its services, particularly under the couch he once sucked tidy dust (you came otherwise not so readily with a normal vacuum cleaner including (huge lounge couch)). Unfortunately, he drives very chaotic through the area where one wonders, he creates the crumbs that next to his "tour" are absorb in an hour? Most already. Sometimes our Concern, lift it up and sit down at the place where he has not sucked ;-). One should perhaps in large rooms (we have about 45 square meters) create demarcations, so that the vacuum cleaner sucks only certain areas and then also creates. For some deep pile carpets unsuitable (predominantly have Laminate and stone floor). For the price it is ok, in the corners, he is super, bypasses our cabinet with the corners perfectly and by the long "brush", he also creates corners clean. If hair lying on the floor, it may be that this brush entangled (the hairs are at least no longer distributed on the floor). I also believe that the increase to 17 Watt, who in contrast to its predecessor, done him good.
