Stealth has 12 height adjustments to allow you to vacuum exactly as you wish. At most, other vacuums have 5 levels and air driven brushes like Turbo Cat have no height adjustments. You need a brush you can adjust to the perfect setting. Stealth is also unique because it governs its RPM. Do note though, that any vacuum you "float" on the carpet will, at times, spit out small debris because the brush is not digging into the carpet, but the carpet will last longer because it is not being roughed up.
