Using a carpet shampooer keeps your carpet fresh and clean. These cleaners resemble a vacuum cleaner but with a hot water extractor that produces warm, sudsy water to clean the carpet. The shampooing machine has a solution tank and cleaning attachment with a nylon brush. The brush spins and releases the cleaning solution into the carpeting, which creates foam. Moving in a circular fashion, the brush scrubs the carpeting. It uses suction to remove the water and then sends the water to a dirty water reservoir. They’re really not that hard to use, and they can save you an absolute fortune in professional carpet cleaning!
