摘要： An accessory tool for an extraction cleaner having an accessory hose, a fluid delivery system, and a fluid recovery system includes a lens, a tool body, a spray tip, and a cleanout assembly. The tool body is connectable to the fluid delivery system and the fluid recovery system via the accessory hose. The lens couples to the tool body to form a suction nozzle volume therebetween. The tool body defines a fluid channel opposite the lens. The spray tip dispenses a cleaning fluid from the fluid delivery system onto a surface during a spray cycle of the extraction cleaner. The cleanout assembly selectively diverts the cleaning fluid from the spray tip and into the suction nozzle volume via the fluid channel during a clean out cycle of the extraction cleaner to thereby clean the lens and the accessory hose.
