I bought a shark, the red model, with a little battery-charged sweeper. I hate the vacuum. The dirt, "cup" is hardly bigger than a coffee cup and fills up within minutes. After a couple of months it just quit picking up. I do like the little sweeper for floors though. I would not recommend it. You would be better off with a automobile hand-held vacuum.
