I just received this attachment and I didn't know what to expect. I really didn't think the wind brush would rotate at all because it felt like it had to be rotated by hand. What's good: the rotating brush spins like a bat! You know, the ones that fly out of hell. I tried it by collecting dog hair from a long haired dog and it worked. Then I sprinkled some baking soda on the carpet and made sure it caught. And again everything turned out in one go! So he picks up large and small and quickly processes the room in one go. The bad: I turned it off and checked the brush. All collected furs were carefully wrapped around the brush. ☹️ All of this took me about two minutes, but I don't recommend it for people with long-haired pets. It's probably great for short hair. I still gave it 4 stars because the company doesn't charge a ton for it and it actually works quite well.
