  • Carpet cleaner and method for cleaning carpets
    Patent number: 5813086
    Abstract: A carpet cleaner for cleaning carpets includes a foam generation unit, roller brushes and a heated air drying mechanism. The foam generation unit uses multiple stages of foam generation for creating a very fine foam which is applied to the carpet.

The carpet is cleaned, dried and ready for immediate use.
