I'm changing my review. At first I thought the shark was average. Now I know I could personally lie on the floor and inhale deeply and I would pick up more stuff. All this thing does is pick up some dog hair and then spit most of it back out in big chunks. It is "ok" at picking up larger things, but if something is that big on the floor, just bend over and pick it up yourself. I wanted something that would really work well on my hardwood floors, especially on the dog hair. The people that post that it picks up pet hair must not be able to see well. I think most of them must be blind. Don't waste your money. The only good thing about this is that's it's lightweight and cordless. But I can say that about a lot of things.....
