Abstract
A hard surface cleaner having a cleaning head with rotational assist. In one embodiment, the cleaning head includes a housing having a fluid-supply and vacuum inlets. The housing also includes at least one flow-control inlet arranged with the vacuum inlet to draw a flow of air into the housing through the flow-control inlet. The cleaning head further includes a spray assembly at least partially enclosed within the housing. The spray assembly includes a shaft, at least one spray nozzle operably coupled to the shaft, and a plurality of fins also operably coupled to the shaft. The spray nozzle is configured to receive a pressurized fluid from the fluid-supply inlet and to rotate about the shaft by delivering the pressurized fluid toward a floor surface. The fins are positioned at least partially within the flow of air through the flow control inlet to control the rotational speed of the spray assembly.
