I thought this would easily take the hair up off of the carpet on my stairs, and of of the dog's bed. It doesn't. When the spinning bristles make contact with anything, it slows them down so dramatically that they don't pick up anything. So, you just sit there going back and forth over the same spot, looking at the same hair. I love my Dyson, but this tool is junk. I ended up just plopping my dyson over top of the dog's pillow. That works much better.
