Abstract: A window wiper is provided. A wiper blade assembly includes a wiper blade and a mounting part. The wiper blade includes a first layer and a second layer which are arranged in a layered manner. The first layer is a scrubbing layer made of a rubber material, silica gel material, soft PVC material or EVA material, and the second layer is a guide layer made of a water-absorbing material. A rear end of the wiper blade is connected with the mounting part, and its front end is a free end. The window wiper includes the wiper blade assembly, a wiper blade mounting frame and a handle, wherein the wiper blade mounting frame is provided with a water receiving port. When the wiper blade assembly is mounted on the handle through the wiper blade mounting frame, the guide layer is located above the water receiving port.

Abstract: A cleaning device includes a handle having a longitudinal axis, a cleaning element movably coupled to the handle, and a flexible conduit fluidly connectable to the cleaning element. The flexible conduit is positionable within an interior of the handle. The cleaning element is movable relative to the handle about a first axis and a second axis when the flexible conduit is fluidly coupled to the cleaning element. The first axis and the second axis are arranged at an angle relative to the longitudinal axis.

Abstract: A water-fed pole for window cleaning including: an extendable pole having two or more pole sections, the pole sections being moveable relative to each other, in use, to extend and shorten the pole; and one or more clamps, each clamp being coupled to a given pole section and being operable to clamp the given pole section to an adjacent pole section, thereby fixing, in use, the length of the pole. Each clamp including a clamping surface arranged such that, on operation of the clamp, the clamping surface is brought into contact with a surface of the adjacent pole section to clamp the given pole section to the adjacent pole section. The at least a portion of the clamping surface made up of a resilient material.

Abstract: A window cleaning kit for cleaning elevated windows includes a pole, which is tubular, and a pump module. The pump module comprises a reservoir that is configured to position a respective solution. A hose is selectively couplable to a lower end of the pole and the pump module and is positioned to fluidically couple the pole to the reservoir. A scrubber and a spray head are selectively couplable to an upper end of the pole. The pump module is configured to selectively pump the respective fluid positioned in the reservoir through the hose and the pole to the scrubber and the spray head. The scrubber is configured to scrub a window and the spray head is configured to spray the window.

Abstract: A squeegee device (10) for cleaning includes a main supporting base (20) in which an opening (24) is formed along a cleaning width direction of a cleaning surface (W), and a pair of squeegees (30) and (40) arranged to extend along the cleaning width direction along the periphery of the opening (24) and formed of an elastic body. Tips of the pair of squeegees (30, 40) are arranged at an angle relative to each other and contact each other in an airtight state, and pressing the tips against the cleaning surface (W) can open a gap between the tips.

Abstract: The invention is a windshield washer preparation, a method for producing the preparation and a device that produces the preparation. The method uses the dehydration of methanol and distillation of dimethyl ether to produce the preparation and a propellant for pressurized packaging. The washer preparation contains deionized water, methanol, dimethyl ether, dimethyl carbonate and additional compounds selected from the group consisting of dyes, de-foaming agents and surfactants. The disclosed method and device can formulate varying combinations of methanol, deionized water and dimethyl ether using the methanol dehydration reaction prior to the addition of dimethyl carbonate. The preparation can be used in automobile washer reservoirs or directly on the windshield using trigger spray applicators or an aerosol can. The excess dimethyl ether from the method can be used taken from the system and stored for future use.
