Over the last 30 years, I think I have had 4 of these. The Spin Scrub Brushes are much better for the carpet fibers than the rotating brush as found on a vacuum. These brushes are more effective at loosening stains, spills. The rotating brushes pull out carpet fiber. You might be tempted by the more expensive machines from hoover, but actually this is your best buy. Currently on basset hounds 4 & 5, and they approve!
