This thing is awful. I bought this because we have a dog that sheds a lot and after reading other reviews and comparing prices I thought this would suit us well. You can see in the video where he's just spinning his hair in circles. I thought it was full, dirty or clogged so I turned it over, opened everything up, but it wasn't! The photo shows a pile that I swept up with a broom AFTER she ran over the same spot for over 15 minutes. I would not recommend this product! What's even more annoying is that I bought the accessory because it's not from the same seller, so we'll see how the return goes.
