Zusammenfassung:	An extractor (10) is provided for cleaning carpet or a like surface or material. The extractor (10) includes a housing (12), a handle (16), a cleaning liquid delivery system (18) and a cleaning liquid recovery system (20). The cleaning liquid delivery system (18) includes a cleaning liquid supply tank (22), first and second aligned agitators (32, 34) preferably in the form of brushes and a gravity feed or pump for delivering cleaning liquid from the supply tank (22) for cleaning. The cleaning liquid recovery system (20) includes a recovery nozzle (56), a vacuum generator (58) and a dirty cleaning liquid recovery tank (60). The extractor (10) is further characterized by a manifold for receiving cleaning liquid from the pump and directing the cleaning liquid into a nip defined between the first and second agitators (32, 34). A drive assembly counterrotates the agitators (32, 34) so that relative rotation of the agitators (32, 34) in the nip is generally away from the manifold and toward the carpet to be cleaned.
