No magic but very effective.

This brush is not magic: you have to switch back and forth, pressing carpets, but in the end almost everything is drawn (there are still a little bit, I checked with a hand brush). That made up for my two cats ragdolls I began to hate despite their kindness!
Indeed, it is very noisy but you get used. There is another drawback is that, according to the mini-manual supplied, this brush fits directly Dyson on some models, but for other models, you need a little extra tip that is not
provided with the brush. And it is not clear to what models this nozzle is required. I have a DC29 and brush fits well.
