Abstract: A self-contained, closed-loop, hard surface and carpet cleaning apparatus includes a carpet cleaner with a power unit and a vacuum tank. A cleaning tool is connected to the power unit via a supply hose, and to the vacuum tank via a return hose. At the operator's business location, the vacuum tank is initially filled with a supply of fresh water passed through a water softening unit. At the job site, the water is pumped from the vacuum tank to a re-circulating tank through a series of filters. Ozone is added to the re-circulating tank to cleanse the water. The water is then passed through charcoal filters, and to the power unit. A cleaning agent is added to the water by the power unit. The water is also heated, pressurized, and delivered by the power unit to the cleaning tool via the supply hose. After the water is sprayed onto a surface being cleaned, it is immediately extracted and drawn back to the vacuum tank through the return hose.
