I have a Bissell Lift-Off Revolution Turbo. Huge name, that. It's an upright with an integrated hose. The brush attachment for the hose spins under wind power. Not as strong as a belt drive, but it does pretty well. A feature that I like is that it has separate switches for power and the main brush, which is belt-driven. Not only that, but the brush shuts off when you lock the handle upright, so you don't wear out a single area of your carpet. Finally, the business section lifts out and becomes a canister vacuum for those occasions when you need one.

I'm pretty happy with it.
