A carpet extractor valve assembly (340,522) alternately directs cleaning solution to a base-mounted spray bar (74,526) or to a remote distributor (438,614) of an accessory tool (16,524). The valve assembly includes an inlet port (344), which receives cleaning fluid from a handle-mounted reservoir (14,574), and first and second discharge ports (400, 442), connected to the spray bar and the accessory tool, respectively. First and second valve members (352,354) include first and second poppets (362, 444), which are biased by a spring (384) to normally-closed positions in which the first and second discharge ports are sealed. A trigger-operated actuation rod (410) actuates the first valve member to release cleaning fluid to the spray bar. A quick connect coupling (464,466,608,610) connects the remote distributor with the second discharge port and opens the second valve member thereby. In one embodiment, a cleaning solution pump (480), mounted in a pump housing (490) over a base assembly A, is coupled between the valve assembly (340) and the remote distributor (438). In another embodiment, a pump (520) is connected between a cleaning solution tank (574) and the valve assembly inlet port and pressurizes cleaning fluid for both the spray bar (526) and the remote distributor (614).
