First, Dyson has a really cool English Designer, and when he talks, everyone gets caught up in his proper english and believe he's right. He is, his patented system is cool as hell. That's where it stops. Try luggn' that load up the stairs or moving it around...if everyone had a Dyson, we wouldn't be the fattest country in the world. Oreck is Lightweight, JUST as powerful as a Dyson and the dust bags are easy to use and bio degradable. The power of the this unit pulls itself, so the small wheels really don't matter, I don't know what that other guy is talking about. I have 2 Orecks. One base cheapy and a heavier duty one, they work great, and if they lose power or crap out, you bring them in to the store and get them fixed. It's like owning a car, not like owning a Iphone. They aren't disposable. You just get them fixed and they work like new. Nuff Said!
