An accessory tool (10T) usable with an extraction cleaner (12, 120, 220) for cleaning a surface (11) includes a tool body (10), fluid reservoir (54), and porous spray bar (55). The tool body (10) defines a fluid pathway (50), an airflow pathway (52), and a suction nozzle (20) connected to the airflow pathway (52), and connects to the extraction cleaner (12, 120, 220) via an accessory hose (13). The fluid reservoir (54) is in fluid communication with the fluid pathway (50) and carried by the tool body (10). The porous spray bar (55), which is coupled to the tool body (10) adjacent the fluid reservoir (54) and surrounded by the suction nozzle (20), directs cleaning fluid (34) from the fluid reservoir (54) onto the surface (11). The fluid pathway (50) connects via the accessory hose (13) to a fluid delivery system (30) aboard the extraction cleaner (12, 120, 220) to receive the cleaning fluid (34) and direct the cleaning fluid (34) to the fluid reservoir (54). The airflow pathway (52) connects the suction nozzle (20) via the accessory hose (13) to a fluid recovery system (18) aboard the extraction cleaner (12, 120, 220).
