I have cats, wanting a zip brush to clean off cat fur off my furniture. tried this. It is terrible, besides being heavy in your hand, if you are going on a corner the wand rotates makes it hard to get to the arm of chair Then what realy made me mad! it snagged my sofa! on the seat cushion!
CentralVac recommended this attachment for my stairs. I returned it because it was too hard to use and too small. Very ineffective. It added to the chore of vacuuming the stairs - it did not make it easier.
