With the Rug Doctor Deep Carpet Cleaner, you can get professional cleaning results on your own schedule. This carpet cleaner features 75% more suction than leading comparable upright deep carpet cleaners. And it uses dual cross-action brushes—two brushes under the machine. This innovative technology deep cleans each carpet fiber, then grooms and polishes the carpet all in one cleaning pass. Not every carpet needs the same level of deep clean, some need a 'Super Boost' to get the carpet completely clean. Use the 'Super Boost Spray' setting on the machine for an added power boost while cleaning heavily soiled and high-traffic areas. Your Rug Doctor Deep Carpet Cleaner is ready to start cleaning right out of the box. There's no assembly required!
