An automatic and currentless dirt remover for collecting dirt from the area surrounding the dirt remover, having a dirt-collecting body and a rolling-action sheath body, which defines a receiving space for receiving the dirt-collecting body. The sheath body has a lattice design and openings for providing external access to the dirt-collecting body, which has a surface that collects the dirt.

A self-cleaning food processor includes a body and a crushing assembly. The crushing assembly includes a cup body, a cup lid, a crushing electric motor and a crushing device, wherein the cup lid cooperates with the cup body to form a crushing cavity, an output shaft of the crushing electric motor extends into the crushing cavity, the crushing device is located in the crushing cavity and is connected to the output shaft of the crushing electric motor, and the volume of the crushing cavity is V1. A cleaning process is provided after the food processor completes food processing, and in the cleaning process, cleaning water, the volume of which is no less than V0, is injected into the cup body at least twice, and the crushing device is controlled to drive the cleaning water to move in the crushing cavity, wherein 0.2V1≤V0≤0.6V1.

A lint brush includes a housing and a lint tool having a lint-removing material. The lint tool is movable along a longitudinal axis of the housing between a stowed position where the lint tool is housed in the housing and a deployed position where the lint tool is extended from the housing. The lint tool is rotatable relative to the longitudinal axis from the deployed position to a first rotated position. An actuator is mounted to one of the housing and the lint tool. The actuator is configured to move the lint tool from the first rotated position back to the deployed position.

A lens and/or a view screen of an electronic device having at least one case can be cleaned by wiping the view screen with a cleaning component wherein the cleaning component is configured to selectively couple to the at least one case or some other substrate using a magnetic attractive force. The cleaning devices may have secondary applications such as securing fly fishing lures, activating or deactivating a device having a magnetic switch, or preventing sunglasses from sinking. They may also be manufactured without a cleaning component for use with the secondary applications.

The present invention relates to a high-performance adhesive roll cleaner including: an adhesive tape roll formed by winding an adhesive tape, having an adhesive layer formed on one surface of a warp-knitted fabric base layer, so that the adhesive layer faces outward; and a support body configured to rotatably support the adhesive tape roll; wherein the warp-knitted fabric base layer may be continuously cut at intervals of 2 mm. The present invention may provide remarkable advantages in that the adhesive tape may be easily cut at a desired position during use, and may be used repeatedly due to the excellent initial tack thereof, so that the economic efficiency thereof may be maximized while the waste thereof is prevented.

Provided is, for example, a cleaner sheet including: a cleaning surface that is configured to be brought into sliding contact with a surface of an object to be cleaned. The cleaning surface has unevenness, and includes projections respectively having distal ends configured to be in sliding contact with the object to be cleaned when in use. The projections are constituted by a member formed to have the projections arranged at intervals from each other in a plane direction of the cleaning surface. The member has a hardness of 0.4 MPa or more measured by a nano-indentation method. The cleaning surface further includes adhesive recesses that have higher adhesive force than that of the member and are exposed on the cleaning surface.
