A rotary surface cleaning machine for cleaning floors, including both carpeted floors and uncarpeted hard floor surfaces including but not limited to wood, tile, linoleum and natural stone flooring. The rotary surface cleaning machine has a rotary surface cleaning tool mounted on a frame and coupled for high speed rotary motion relative to the frame. The rotary surface cleaning tool has a substantially circular operational surface that performs the cleaning operation. The rotary surface cleaning tool is driven by an on-board power plant to rotate at high speed. The rotary surface cleaning tool is coupled to a supply of pressurized hot liquid solution of cleaning fluid and a powerful vacuum suction source.

The present disclosure is directed generally to waste water vessels with multiple valved chambers, and associated systems and methods. A method in accordance with a particular embodiment includes drawing waste water into a first chamber under vacuum while the first chamber and a second chamber have at least approximately the same internal pressure. The method further includes allowing the waste water to pass from the first chamber to the second chamber while the first chamber and a second chamber have at least approximately the same internal pressure, releasably sealing the first chamber from fluid communication with the second chamber, and simultaneously adding waste water to the first chamber and removing wastewater from the second chamber while the first chamber is sealed from fluid communication with the second chamber.

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.
