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 and provides a fluid flowpath 182 for dirty cleaning fluid from the floor surface to the recovery tank. The nozzle assembly is pivotable from a first position, in which the fluid flowpath communicates with the recovery tank, to a second position, in which the nozzle assembly is spaced from the recovery tank to allow the recovery tank to be removed from the base housing. A second flowpath 138 is formed on the recovery tank between the tank and a nozzle plate 136. The flowpaths 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 during above floor cleaning.
