Powerful rotating brush lifts deep-down dirt as you wash carpet. Deep cleaning is a carpet cleaning process that loosens and removes most harmful dirt and ground-in grit, which may be deep down in your rugs and carpets. The deep cleaning process combines vacuum suction, brushing action, hot water and cleaning solution to clean beyond the surface of your carpet. Not only does frequent deep cleaning protect the investment you have in your home, but parents of young children, pet owners and allergy sufferers may find deep cleaning especially beneficial.
