Abstract
A carpet or rug cleaner forms a bead of water or other cleaning fluid across the width of a cleaning head. The bead of fluid is applied on the pile of a carpet or rug, and the fluid is violently pulled, by the force of the applied vacuum, from the bead or from the region of the bead through the pile of the carpet or rug to a vacuum uptake with only limited downward penetration of the fluid into the pile. Cleaning action is vigorous, fluid recovery is enhanced, and drying time reduced.
