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.

A surface cleaning apparatus having a housing, a suction nozzle, a suction source, a steam port, a steam supply system, and a flexible seal. The housing having a cleaning foot and an upper housing operably coupled to the cleaning foot. The suction source being fluidly connected to the suction nozzle by a working air conduit. The steam port having an aperture provided in the cleaning foot. The steam supply system having a steam nozzle with at least a portion that projects through the steam port. The flexible seal being provided at least around the steam nozzle.

Disclosed are a cleaning roller and a rolling steam mop. The cleaning roller includes a central shaft capable of rotating, a steam channel, and a cleaning layer. The steam channel is provided with a steam inlet and a plurality of first steam outlets; the steam inlet is used for communicating with a steam generation device: the plurality of first steam outlets are distributed in an axial direction of the central shaft. The cleaning layer is provided around the central shaft; and the steam flowing out from the first steam outlets can be diffused outwards through the cleaning layer When in use, the steam generated by the steam generation device enters the steam channel through the steam inlet, and then flows out from the first steam outlets, and is diffused outwards through the cleaning layer, so that the steam can be diffused to an object to be cleaned.

A hand vacuum cleaner and a mounting structure for the hand vacuum cleaner. The mounting structure has a base which is free standing on a floor and an upper portion comprising an air flow duct and a mounting apparatus provided at an upper end of the upper portion. The mounting apparatus has first and second laterally opposed first engagement members. The hand vacuum cleaner has first and second laterally opposed second engagement members. The hand vacuum cleaner is downwardly removably mountable to the mounting apparatus and the first and second engagement members are slideably interengagable. As the hand vacuum cleaner is moved downwardly to be mounted to the mounting apparatus, the first and second engagement members slideably interengage.

An extraction cleaning machine includes a housing with a bottom portion that is adapted to rest on a surface to be cleaned, a fluid delivery system including a fluid distributor, a fluid extraction system including a suction nozzle, at least one carriage assembly mounting an agitation assembly to the housing for movement with respect thereto and with respect to the surface to be cleaned, and an ultraviolet light mounted on at least one of the housing and the carriage assembly to emit ultraviolet light onto the surface to be cleaned.

An unattended extraction cleaning machine includes a housing with a bottom portion that is adapted to rest on a surface to be cleaned, a fluid delivery system including a fluid distributor, a fluid extraction system including a suction nozzle, at least one carriage assembly mounting the suction nozzle to the housing for movement with respect thereto and with respect to the surface to be cleaned, and an ultraviolet light mounted on at least one of the housing and the carriage assembly to emit ultraviolet light onto the surface to be cleaned.

An autonomous mobile steam cleaning device includes a mobile robot being formed with a hot steam/vapor generator and a first water tank with hot water during autonomous steam cleaning; a base station providing either hot water or water and power to pre-heat water to the first water tank before autonomous steam cleaning commences; and a steam dispersing apparatus provided with at least one steam port in communication with the hot steam./vapor generator.

A surface cleaning apparatus includes a housing including an upright handle assembly and a base mounted to the upright handle assembly and adapted for movement across a surface to be cleaned. The surface cleaning apparatus is further provided with a fluid delivery system comprising a fluid dispenser configured to dispense fluid to a brushroll and at least one fluid delivery channel forming a portion of a fluid delivery pathway. The fluid delivery channel can extend adjacent to a portion of the suction nozzle assembly. An interference wiper interfaces with a portion of the brushroll to remove excess liquid from the brushroll.

The present disclosure provides a surface cleaning apparatus that includes a steam delivery system for steam mopping a floor surface after sweeping dry dirt, dust, hair, and other debris from the floor surface. The surface cleaning apparatus can be configured to perform multiple cleaning functions, including dry sweeping and steam mopping. The surface cleaning apparatus can be convertible between different modes of operation, including at least an upright mode and a handheld mode.
