  • Patent number: 4723337
    Abstract: A single unit readily portable carpet and rug cleaning apparatus receives water directly from any spigot into a high pressure pump without the necessity for a clean water holding tank. Shampoo or cleaning concentrate from an outside container is delivered by siphoning to the incoming water stream being delivered to the high pressure pump. The high pressure cleaning liquid is delivered through a high pressure line extending along a vacuum wand directly onto the carpet or rug through a high pressure nozzle close to floor level. Simultaneously, water and dirt are withdrawn from the carpet or rug through a suction head and delivered through the vacuum wand and a vacuum hose to a dirty water holding tank within the apparatus by the action of twin vacuum motors. When the recovered dirty water reaches a certain level in the holding tank, a float actuates a switch causing the dirty water to be pumped from the holding tank into any convenient drain, commode, laundry tray or sewer.
