Abstract

A carpet extractor includes a base assembly (A) with a two part base housing (10). Upper (22) and lower portions (24,528) of the base housing define a socket (100), for receiving a cleaning fluid recovery tank (120,552), and a chamber (50), rearward of the socket, for receiving a suction fan (82,540) and associated motor (80,542). The chamber includes front (78,544) and rear compartments (546,76) for receiving the suction fan and motor, respectively. The lower portion (22,528) of the base housing defines a first pocket or indentation (70,550) for receiving a motor (68,548) for driving a rotating brushroll (60) and a second pocket (532) for receiving a solution supply pump (520) which selectively supplies pressurized cleaning fluid to a spray bar (526) and a remote distributor (614). The pocket and indentation are positioned rearward of the socket, and generally beneath a forward end of the chamber. The location of the fan, fan motor, pump, and brushroll motor behind the recovery tank socket provides for the accommodation of a large capacity recovery tank, while maintaining a low-profile base assembly.
