I had a green one (My favorite color), and it was a pretty good vacuum. Fairly quiet, lightweight, good suction. My only issue with it was that it was a major pain to change the belt (If I remember right, either 8 or 10 screws), and the attachment clip that holds the wand and crevice tool snapped off. It is essentially a 3 speed motor- Normal, Hush mode, and a power boost button on the handle that can be locked on. The power boost overrides normal and hush, taking it to full speed, either for just a second, like to clean an especially dirty area, or locked on for maximum power full time.
