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.

1. A cleaning head, comprising: a housing having a fluid-supply inlet, a vacuum inlet, and at least one flow-control inlet, wherein the vacuum inlet is positioned to draw a flow of air through the flow-control inlet;a spray assembly at least partially enclosed within the housing, wherein 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, wherein: the shaft includes a passageway in fluid communication with the fluid supply inlet;the spray nozzle is arranged to receive a pressurized fluid from the fluid-supply inlet;the spray nozzle is positioned and oriented downwardly to rotate with the shaft; andthe fins are positioned at least partially within the flow of air through the flow-control inlet;a spray bar fluidly coupling the passageway of the shaft with the nozzle; anda round plate rotatably coupled to the shaft and configured to carry the spray bar, the nozzle, and the fins, wherein: the plate includes an outer surface and an inner surface at least partially surrounded by the outer surface; andthe inner surface is positioned below the outer surface. 2. The cleaning head of claim 1, further comprising a louver operably coupled to the housing and configured to adjustably cover the flow-control inlet to control the flow of air flow through the flow-control inlet. 3. The cleaning head of claim 1 wherein the flow control inlet comprises a plurality of openings extending through a wall of the housing, wherein the louver is configured to adjustably cover the openings. 4. The cleaning head of claim 1 wherein the flow control inlet comprises a single opening extending through a sidewall of the housing, wherein the louver is configured to adjustably cover the opening. 5. The cleaning head of claim 1 wherein the housing at least partially defines an enclosure, and wherein the plate is configured to separate an upper region of the enclosure from a lower region of the enclosure to control turbulance within the enclosure. 6. The cleaning head of claim 1 wherein: the nozzle is disposed toward a periphery of the plate, andthe plate includes a notch through which the nozzle extends downwardly. 7. The cleaning head of claim 1 wherein each of the fins projects beyond the outer surface of the plate. 8. The cleaning head of claim 1 wherein each of the fins extends between the inner and outer surfaces of the plate. 9. A surface cleaning system, comprising: a transport assembly;a cleaning head operably coupled to the transport assembly, wherein the cleaning head at least partially defines an enclosure, and wherein the cleaning head includes:a housing at least partially defining an enclosure, wherein the housing includes: a wall;a fluid-supply inlet positioned to deliver a fluid to the enclosure;a vacuum inlet positioned to draw a vacuum on the enclosure;a flow-control inlet positioned related to the vacuum inlet to draw ambient air into the enclosure and toward the vacuum inlet; anda spray assembly disposed in the housing, wherein the spray assembly includes: a rotatable plate having an outer surface and an inner surface at least partially surrounded by the outer surface, wherein the inner surface is positioned below the outer surface;a spray bar operably coupled to the plate and positioned to receive fluid from the fluid-supply inlet, wherein the spray bar includes individual spray nozzles disposed at opposing ends of the spray bar configured to deliver the fluid; anda plurality of fins operably coupled to the plate and positioned to be at least partially within the flow of the ambient air drawn into the enclosure. 10. The system of claim 9 wherein the transport assembly comprises a columnar frame and a hinge operably coupling the frame with the cleaning head. 11. The system of claim 9 wherein the transport assembly comprises a wand having a handle and a tubular member operably coupling the handle with the cleaning head. 12. The system of claim 9 wherein the transport assembly comprises a wheeled chassis, and wherein the system further comprises: a fluid supply fixture carried by the chassis and fluidly coupled to the fluid-supply inlet;a first pump carried by the chassis and coupled to the spray bar to pressurize the fluid delivered to the nozzles;a vacuum source carried by the chassis and coupled to the cleaning head to remove spent fluid from the enclosure;a vessel carried by the chassis and coupled to the cleaning head to contain the spent fluid removed by the vacuum source; anda second pump carried by the chassis and coupled to the vessel to remove the spent fluid from the vessel. 13. The system of claim 9 wherein the rotatable plate has a generally round shape. 14. The system of claim 9 wherein the spray bar is between a portion of the wall of the housing and the outer surface of the plate. 15. The system of claim 9 wherein the flow control inlet comprises one or more openings extending through a portion of the wall, and wherein the louver is configured to adjustably cover the one or more openings. 16. A surface cleaning system, comprising: a housing having a fluid-supply inlet, a vacuum inlet, and at least one flow-control inlet, wherein the vacuum inlet is positioned to draw a flow of air through the flow-control inlet; anda spray assembly at least partially enclosed within the housing, wherein the spray assembly includes: a shaft,at least one spray nozzle arranged to receive a pressurized fluid from the fluid-supply inlet,a plurality of fins operably positioned at least partially within the flow of air through the flow-control inlet, anda rotatable plate operably coupling the at least one spray nozzle and the plurality of fins to the shaft, wherein the rotatable plate includes an inner surface that is positioned to: face a floor surface and be separated therefrom by a gap; andimpart momentum to spent fluid in the gap for removal via rotation of the plate in combination with surface tension at the inner surface. 17. The cleaning system of claim 16 wherein the rotatable plate further includes an outer surface facing away from and surrounding the inner surface. 18. The cleaning system of claim 16, further comprising a fluid supply fixture configured to containing a cleaning fluid;a pump configured to pressurize the cleaning fluid and to deliver the pressurized fluid to the at least one spray nozzle;a chassis carrying the fluid supply fixture, the pump, the housing, and the spray assembly. 19.
