I had my doubt about this vacuum when I first saw how small it was. I decided I'd try it out on a simple crumb pile that builds up around our dogs food dish. It sucked it right up now problem. So then I figured I'd try it on something tougher. Our dog have fine silky hair that weaves it's self into the fabric of our couch and he sheds a lot. Generally I have to run the vacuum over th same spot 3 to 4 times to get all the dog fur up but with this it was one swipe and gone.
