A mist generating system for a cleaning implement is adapted to generate a finely atomized liquid mist for suppressing dust, allergens, and other airborne particulates. The mist generating system can be adapted to fit many cleaning implements such as vacuum cleaners, wet extraction cleaners, floor mops, and dusters to suppress airborne dust and particulates generated during operation and the cleaning process.

Aspects of the present invention relate to a triggerless extractor surface cleaning device for cleaning a surface in which a cleaning solution is distributed to the surface and extracted using suction along with dirt and/or debris on the surface in a continuous operation as the extractor moves along the surface. The extractor further comprises an encoder positioned adjacent a wheel of the extractor for detecting a rotational direction and speed of the wheel to generate a signal. Based on receiving the signal, a controller controls operation of a valve to situationally distribute the cleaning solution to the surface depending on a forward rotation of the wheel and independent of user actuation of a trigger positioned on a handle used to propel the extractor along the surface. Distribution of the cleaning solution can be further optimized based on the detected rotational speed of the wheel.

An apparatus may include a first layer that includes a plurality of inlets and a surface feature; a second layer, where the surface feature opposes the second layer; an outlet, and a pattern defined on at least one of the first layer and the second layer, where the pattern defines a suction path from each inlet of the plurality of inlets to the outlet.

There is described a novel cleaning device for a condenser of a chiller system comprising: a condenser provided with a cooling grid, said cooling grid comprising one or more fins; a dust extraction system configured to remove dust from the surface of the one or more fins of the grid and/or the condenser.

An extraction cleaner for a floor surface comprises a fluid delivery system for storing cleaning fluid and delivering the cleaning fluid to the surface to be cleaned and a fluid recovery system for removing the spent cleaning fluid and dirt from the surface to be cleaned and storing the spent cleaning fluid and dirt. The fluid delivery system can further include a bladder housed within a tank of the recovery system, and the bladder can be closed by a fill cap.

A wet-dry vacuum cleaner including a collecting bin and a power head removably coupled to the collecting bin. The power head includes a housing configured to support the power head on the collecting bin, an exhaust outlet, and a cyclonic separator positioned within the housing. The cyclonic separator includes a dirty air inlet, a chamber, and a clean air outlet. The power head further includes a suction motor assembly operable to create a working airflow path from the dirty air inlet to the exhaust outlet, and a filter disposed within a filter housing hanging downwardly from the suction motor assembly. The filter is positioned within the working airflow path adjacent the clean air outlet of the cyclonic separator.

A vacuum accessory tool is provided. The vacuum accessory tool includes a body, a turbine, a generator, and a light source. The body defines a suction inlet, a fluid outlet, and a fluid flow path extending from the suction inlet to the fluid outlet. The turbine is rotatably mounted to the body in fluid communication with the fluid flow path to be rotated by fluid passing through the fluid flow path. The generator is coupled to the turbine such that rotation of the turbine rotates the shaft to generate power. The light source is electrically coupled to the generator and configured to receive the power generated by the generator to power the light source by the fluid passing through the fluid flow path.

A hand vacuum cleaner may include a suction motor and fan assembly that is positioned downstream of a pre-motor filter. A post motor filter may be positioned downstream of the suction motor and fan assembly and may be in the lower end of the hand vacuum cleaner and an energy storage member may be in an upper end of the handle.

Surface cleaning device, comprising a cloth (C) placed on a porous material (PM), a reservoir (R) for collecting liquid absorbed by the cloth (C), and an arrangement (P) for applying under-pressure in the reservoir (R) so as to transfer liquid from the cloth (C) into the reservoir (R). A pore size of the porous material (PM) is between 1 μm and 50 μm.
