A vacuum cleaner including a suction inlet, a conduit in fluid communication with the suction inlet, a filter having a valve releasably connected to a filter inlet, the filter configured to collect debris drawn through the suction inlet. The vacuum cleaner further comprising a release mechanism moveable from a first position to a second position. In the first position, the filter is in fluid communication with the conduit to collect debris with the valve being open, and in the second position, the filter is disconnected from the conduit with the valve being closed. Movement of the release mechanism between the first and second positions closes the valve.

The present disclosure relates to a cleaner including a cleaner main body including a battery and a handle configured to be grasped by a user, a cleaning module detachably coupled to the cleaner main body and configured to eliminate debris on a floor surface, an auxiliary battery housing detachably coupled to the cleaning module, and an auxiliary battery detachably coupled to the auxiliary battery housing and configured to supply power to the cleaner main body or the cleaning module, thereby allowing a user to easily manipulate the cleaner while supplying additional power from the auxiliary battery.

Disclosed herein are various embodiments of a system and method for operating a surface pressure washer with a wand component. The method may include the steps of cleaning a first surface through a first fluid path, where the first fluid path includes a pump, a pressure regulating valve, a diversion block, and a spray gun, while spray nozzles are not discharging fluid to a second surface, actuating a valve connected to the diversion block, thereby reducing the pressure available to the first fluid path and creating a second fluid path, where the second fluid path includes the pump, the pressure regulating valve, the diversion block and the spray nozzles, where the spray nozzles are configured to rotate above the second surface when the second fluid path is open, and cleaning a second surface underneath the pressure washer system through the second fluid path.

A cleaning apparatus includes: a main body; wheels movably supporting the main body; a main brush rotatably supported in (by) the main body and configured to brush up refuse on a surface-to-be-cleaned; a first dust unit, which is detachable from the main body and into which refuse brushed up by the main brush is dispatched; a second dust unit, which is detachable from the main body and into which refuse brushed up by the main brush is dispatched; and a dust-collecting assembly comprising: a dust-collecting fan; a dust-collecting motor, which rotates the dust-collecting fan; and an outflow port, from which gas that has passed through the dust-collecting fan flows out; the dust-collecting assembly being configured to suction dust swept up by the main brush. The first dust unit and the second dust unity respectively have a first passageway and a second passageway, into which gas from the outflow port flows.

A surface cleaning apparatus has a cyclone chamber provided in an air flow path. The cyclone chamber has a screen assembly with an outlet section, a longitudinally spaced apart distal section and a longitudinally extending porous section. The outlet section includes a non-porous member extending longitudinally inwardly an outlet section length from an outlet end of the outlet section to a longitudinally inwardly positioned inlet end of the outlet section. The outlet end of the outlet section overlies a cyclone air outlet. The porous section extends longitudinally inwardly from an outlet end of the porous section that is located at the inlet end of the outlet section. The inlet end of the outlet section has a width in a direction transverse to the longitudinal direction that is greater than a width of the outlet end of the porous section in the transverse direction.

A hand vacuum cleaner can include an air inlet conduit having an inlet conduit axis, a suction motor and fan assembly having a suction motor axis of rotation, and an air treatment member. The handle has a hand grip portion that extends upwardly and forwardly and the suction motor is positioned forward of the hand grip portion.

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 senor 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, such as a fluid delivery or steam mop, comprises a handle assembly comprising a steam distributor and a foot assembly pivotally attached to the handle assembly and comprising a base housing. The foot assembly can be used in two positions, whereby opposing sides of a cleaning pad on the base housing can selectively engage a surface to be cleaned. The foot assembly is further swivelable relative to the steam distributor, such that fluid can be delivered to the surface to be cleaned in both of the two use positions.

A portable surface cleaning apparatus for a floor surface includes a main housing assembly adapted to be hand carried by a user, the main housing assembly carrying a fluid delivery system adapted for storing cleaning fluid and delivering the cleaning fluid to the surface to be cleaned, and a fluid recovery system adapted for removing the cleaning fluid and debris from the surface to be cleaned and storing the cleaning fluid and debris that was recovered, the main housing assembly comprising a base housing, a supply tank received on the main housing assembly, a recovery tank received on the main housing assembly separately from the supply tank.
