The apparatus includes an elongate handle to which is attached a cleaning head. The cleaning head includes a forward wall and a striker plate disposed in generally parallel relationship to form a vacuum chamber. A nozzle assembly for dispensing the pressurized fluid is carried by the cleaning head so as to direct the fluid against the striker plate at a point above the carpet surface. Alternative embodiments include the addition of one or more brushes disposed in front of the striker plate. The method includes so directing the fluid so that it is drawn around the edge of the striker plate, through the pile of the carpet and into the vacuum chamber as the apparatus is moved across the carpet.
