A substrate-cleaning apparatus includes a transmission unit, a wet cleaning unit and a dry cleaning unit. The transmission unit includes a movable clamp for clamping a substrate that includes a face without covering the face of the substrate. The wet cleaning unit includes a wiper and a liquid pump. The wiper includes a strip of cleaning cloth and an abutting element for pressing the cleaning cloth against the face of the substrate. The liquid pump sends cleaning liquid to the abutting element that in turn sends the cleaning liquid to the cleaning cloth when the abutting element presses the cleaning cloth against the face of the substrate. The dry cleaning unit includes a wiper comprising a strip of cleaning cloth for wiping dry the face of the substrate without leaving any water mark on the face.

The wipe includes an elongated, shallow v-shaped tissue wipe having proximal and distal ends and, at the terminal proximal end, laterally spaced apart left-side and right-side finger apertures. Upper and lower tissue layers form finger apertures. An angle controller limits the v-shape of the wipe. A plurality of elongated corrugated ribs are longitudinal support elements and the upper tissue layer of said left and right side finger apertures form respective left and right finger tents permitting lateral expansion of the wipe between the finger apertures. Another embodiment has at least two elongated corrugated ribs disposed intermediate the laterally spaced apart left-side and right-side finger tents thereby permitting lateral expansion of said wipe the finger tents. The v-shaped wipe forms a distal excrement collection surface on a distal leg of the wipe longitudinally spaced apart from a proximal leg. The proximal leg terminates at the entrance of the finger tents.

There is provided an oil absorbent pad for cleaning oil on a surface having an oil absorbent body having an upper surface and a lower surface, the body being formed from fiber recovered from recycled tires, and at least one of the upper surface and the lower surface is an outermost layer of the oil absorbent pad.

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.

A window-cleaning robot that includes: a powered agitator that, when active, mechanically removes debris from a window surface; a cleaning pad, which is wetted with a cleaning fluid and contacts the window surface so as to remove debris therefrom with the aid of the cleaning fluid; and a movement system, for example including a number of wheels, which moves the robot over the window surface and has a defined forwards direction; the agitator is located forwards of the cleaning pad and the agitator and the cleaning pad are arranged such that, as the robot moves over the window surface in the forwards direction, the agitator addresses a width in a width direction, which is perpendicular to the forwards direction and parallel to the window surface, that is greater than the width addressed by the cleaning pad.

The present invention relates in particular to a device (1) for fixing a felt for wiping the smooth surface of a cooking appliance, such as the surface of a crepe pan, which includes a gripping member (3) opposite which extends an element (5) with flat smooth surface for receiving a wiping felt (2), characterized by the fact that it includes, at the periphery of said element (5) with flat smooth surface, at least one pinching member (6) and that this element (5) with a flat smooth surface (5) and this pinching member (6) are configured to be selectively moved towards or away from each other to pinch, respectively release, said felt (2).

A sleeve apparatus for protecting a robotic kitchen arm from contamination. The sleeve includes a proximal end, a distal end, a passageway extending from the proximal end to the distal end, and an exterior surface. The passageway has an effective diameter less than the effective diameter of the robotic kitchen arm such that the exterior surface of the sleeve apparatus is substantially fold-free when the robotic arm is in the extended configuration. Methods of cleaning a robotic kitchen arm are also described.

A cleaning apparatus has a first magnetic board device and a second magnetic board device. The first magnetic board device has a first plate body, a first magnet, a first fastening member and a first cleaning pad. The first plate body and the first cleaning pad are attached to each other via the first fastening member. The first magnet is disposed on the first plate body. The second magnetic board device has a second plate body, a second magnet, a second fastening member and a second cleaning pad. The second plate body and the second cleaning pad are attached to each other via the second fastening member. The second magnet is disposed on the second plate body. The first magnet and the second magnet are magnetically attracted to each other, such that the first cleaning pad and the second cleaning pad are located adjacent to and facing towards each other.

A single piece device enables medical clinicians to clean and disinfect both an injection port (needleless I.V. connector) and a vascular access catheter hub. The device has a body with a first end having a blind hole with a wall adapted to be engageable with the threads on the housing of an IV connector and a bottom surface adapted to engage the top surface of the IV connector. The device body has a second end defining a male-luer slip extending out of a recess. The male-luer slip is adapted to extend into a standard vascular access catheter hub such that it engages the inner walls of the catheter hub, and the recess is adapted to receive and be engageable with the outside thread element of the catheter hub.
