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.

Self-cleaning features for extraction cleaners and attachments for extraction cleaners, such as accessory tools, wands, and/or hoses, are provided. The self-cleaning features are configured redirect cleaning fluid from a fluid supply system of the extraction cleaner into a working air or fluid recovery path of the extraction cleaner, including, but not limited to into the working air or fluid recovery path of a tool, wand, and/or hose of the extraction cleaner.

The present invention relates to systems and methods for cleaning materials, such as flooring and upholstery. In some cases, the systems and methods use an electrolytic cell to electrolyze a solution comprising sodium carbonate, sodium bicarbonate, sodium acetate, sodium percarbonate, potassium carbonate, potassium bicarbonate, and/or any other suitable chemical to generate electrolyzed alkaline water and/or electrolyzed oxidizing water. In some cases, the cell comprises a recirculation loop that recirculates anolyte through an anode compartment of the cell. In some cases, the cell further comprises a sensor and a processor, where the processor is configured to automatically change an operation of the cell, based on a reading from the sensor. In some cases, a fluid flows past a magnet before entering the cell. In some additional cases, fluid from the cell is conditioned by being split into multiple conduits that run in proximity to each other. Additional implementations are described.
