Zusammenfassung:	A carpet extractor includes a base assembly (1) including a housing (10) which selectively receives a recovery tank (22) for collecting dirty cleaning fluid. A nozzle assembly (67) is mounted to the base housing (10) and provides a fluid flowpath (182) for dirty cleaning fluid from the floor surface to the recovery tank (22). The nozzle assembly (67) is pivotable from a first position, in which the fluid flowpath (182) communicates with the recovery tank (22), to a second position, in which the nozzle assembly (67) is spaced from the recovery tank (22) to allow the recovery tank (22) to be removed from the base housing (10). A second flowpath (138) is formed on the recovery tank (22) between the tank (22) and a nozzle plate (136). The flowpaths (138,182) have openings (218,140) respectively, at their lower ends, which are located either side of two longitudinally spaced brushrolls (60,62). A flap valve (474) selectively closes both flowpaths (138,182) during above floor cleaning.
