A carpet and floor vacuum device with an improved suction head is provided comprising a curved, fluorinated molding mounted on a vacuum cleaner head. The suction head is designed to move along the surface of the carpet, rather than penetrating into the carpet itself. The polymer molding defines a plurality of inlet perforations laterally-spaced along the curved surface, and the perforations are connected to an air-fed manifold. Following application of cleaning fluid to the carpet or floor, air is fed from the manifold into the carpet or onto the floor. Material including Ingested air, debris and spent liquid, are then removed from the carpet or from the floor and then returned to the perforations from the manifold. This material is then removed to a conventional vacuum collector, thereby drying out the carpet or floor. Use of a curved, fluorinated surface provides a smooth movement along the carpet surface without severely abrading the carpet fibers. When used either on a carpet or floor surface, an air buffer is formed between the suction head, thereby assisting in movement of the vacuuming device. In addition, use of a curved fluorinated surface further reduces abrasion.
