I have a big, black dog of his currently loses Winterfell and have reason ordered this brush for this - she was one of the best. but that it shows in the quality: the brush does not rotate or only in a certain position - thus keeping impossible if one sucks. the transition to the pipe is the total loss of suction, one feels downright the "wind" and a flame flickers like crazy when you holds out. short and bad: the total crap. poor quality, sucks even worse than our normal vacuum cleaner brush and is not even worth the cheap price. habs equal to sent back, useless scrap! just do not buy ..
