I am always very skeptical about such things. I have a Dyson DC 19 and thought I'll get the hair of our two dogs so gone. Nope, I have indeed on the steps into the house and on the ground in the conservatory this durable carpets that you are also in lobbies, but although they are easy to care for the dog hairs have the suck gewuzelt only back and forth until there were little balls that I I then removed by hand. So I ordered this brush on a trial basis. I could not believe it when I tried, it all away and all without effort. The brush glides almost as if by itself, and then, for the steps it is optimal. Even the cheap rugs under the coffee table where my dog is spotless and are happy. For my needs, it is large enough. I do not want to miss and can only highly recommend it.
