Abstract: An accessory tool (10T, 110T) for an extraction cleaner (12, 122, 220) having an accessory hose (13), a fluid delivery system (30), and a fluid recovery system (18) includes a lens (100, 300), a tool body (10, 110), a spray tip (550, 650), and a cleanout assembly (60, 160). The tool body (10, 110) is connectable to the fluid delivery system (30) and the fluid recovery system (18) via the accessory hose (13). The lens (100, 300) couples to the tool body (10, 110) to form a suction nozzle volume (10V, 110V) therebetween. The tool body (10, 110) defines a fluid channel (62, 162) opposite the lens (100, 300). The spray tip (550, 650) dispenses a cleaning fluid (34) from the fluid delivery system (30) onto a surface (11) during a spray cycle of the extraction cleaner (12, 122, 220). The cleanout assembly (60, 160) selectively diverts the cleaning fluid (34) from the spray tip (550, 650) and into the suction nozzle volume (10V, 110V) via the fluid channel (62, 162) during a clean out cycle of the extraction cleaner (12, 122, 220) to thereby clean the lens (100, 300) and the accessory hose (13).

Abstract: A floor cleaning machine can comprise a chassis, a cleaning mechanism, a control system, and a cleaning operation sensing system connected to the chassis. The chassis can be configured for movement along a cleaning path. The cleaning mechanism can perform a cleaning operation. The liquid system can provide liquid to the cleaning mechanism. The recovery system can recover liquid from the cleaning operation. The control system can control performance of the cleaning operation. The cleaning operation sensing system can detect a condition of the cleaning operation. The cleaning operation sensing system can comprise a water trailing detection system comprising: a frame connected to the chassis aft of the recovery system, an absorbent medium connected to the frame; and a moisture sensor in communication with the control system to alter a signal in response to moisture in the absorbent medium.
