A toilet bowl cleaning tool formed from a single sheet (rectangular and water soluble) for removing a stain from a toilet bowl. The sheet has first fold lines that are fold lines parallel to one of sides of the sheet and that divide the sheet at equal intervals, first fold pieces segmented by the first fold lines, and a second fold line used as a reference for folding the sheet into an approximately L-shape in a cross-section of the tool. After the sheet is folded based on the plurality of the first fold lines so that the first fold pieces are stacked to form an approximately rectangular shape whose longer sides are parallel to the first fold lines, the second fold line is provided to be parallel to the longer sides of the rectangular shape and to divide the shorter sides into an approximately half.

A multi-axis variable-speed hot washing module and a hot washing method thereof are provided. The multi-axis variable-speed hot washing module includes a storage assembly, a dehydration assembly, and one or more multi-axis variable-speed hot washing machines, where the multi-axis variable-speed hot washing machine is connected to the storage assembly and the dehydration assembly. Batches of materials are stored in the storage assembly. When cleaning, the materials are put from the storage assembly into one or more multi-axis variable-speed hot washing machines, and medicinal water is added. The multi-axis variable-speed hot washing machine replaces functions of a hot washing machine, a screw, and a friction machine, and has relatively large mechanical friction on the materials during cleaning. The materials after being hot washed by the multi-axis variable-speed hot washing machine are transported to the dehydration assembly for dehydration, so as to implement separation of cleaning water and the materials.

The invention relates to a cleaning device for a yarn forming element of an air-spinning nozzle, to a spinning position of an air-spinning machine and to a method for cleaning a yarn forming element of this type. In order to provide a spinning position of an air-spinning machine and a method for cleaning a yarn forming element of an air-spinning machine which allow long and trouble-free operation with constant quality and strength of the yarn produced, it is provided that the cleaning device has a cleaning strip and a storage unit for providing and retracting the cleaning strip, a fixed end of the cleaning strip being fastened to the storage unit, and a free end of the cleaning strip being able to be provided for cleaning and retracted again after the cleaning. Furthermore, the cleaning device has a cleaning strip guide for feeding the free end of the cleaning strip to the yarn forming element of the air-spinning nozzle for mechanical cleaning.

A sensor of the present disclosure includes a sensor housing with a housing window; a sensor unit arranged in the sensor housing suitable for emitting a sensor signal through the housing window and for receiving a detection signal through the housing window (3); a cleaning unit having a cleaning element, a holder and a drive, wherein the cleaning element is attached to the holder such that the cleaning element is suitable for contacting the housing window from the outside, wherein the drive is non-positively connected to the holder and is suitable for moving the cleaning element across the housing window; and a pressing unit which is suitable for exerting an adjustable contact pressure on the cleaning unit so that the cleaning element is pressed against the housing window with the contact pressure.

A cleaning head for a marine cleaning system used for cleaning a liquid submerged surface includes a body configured to be disposed adjacent to and moved relative to the submerged surface during use. The body defines at least one suction aperture being in fluid communication with a suction region adjacent the body. At least one support arm extends from the body, which support arm in turn supports a respective cleaning element including a scraping blade that is configured to cause material on the submerged surface to separate from the submerged surface and become suspended in the suction region during use. The material separated from the submerged surface is drawn away from the suction region through the at least one suction aperture. Each support arm extends flexibly from a respective junction with the body so that the cleaning element is supported in a spaced relation laterally away from the junction with the junction being disposed in an operatively forward direction of the cleaning element during use.

A cleaning tool for an aerosol-generating device is provided, the cleaning tool including an elongate body having a proximal end portion and a distal end portion, the distal end portion defining a recess configured to receive a heating element of an aerosol-generating device, the recess extending from an opening in a distal end face of the elongate body towards the proximal end portion of the elongate body, the distal end portion of the elongate body being provided with at least one protrusion inwardly projecting into the recess, and the elongate body further including a scraping surface at the distal end face of the elongate body.

A HEPA-qualified coating removal system, coating removal tool, and method is disclosed. The HEPA-qualified coating removal system comprises a HEPA-vacuum coupled to a coating removal tool via a vacuum line. A method of using the HEPA-qualified coating removal system includes, but is not limited to, the steps of the user putting on appropriate protective equipment, connecting the vacuum line of the HEPA-vacuum to an outlet of the coating removal tool, activating the HEPA-vacuum, using scraping motion of coating removal tool to strip a surface and the resulting loose debris being removed by suction force from the environment, deactivating the HEPA-vacuum, and disposing of the debris collected in the HEPA vacuum.

A dipstick assembly includes a first handle attached to an end of the rod, a second handle including a second handle opening configured to receive the first handle and the rod, and a cleaning pad disposed at the bottom end of the second handle. The cleaning pad is configured to receive the rod and contact the rod to clean the rod when the first handle and rod are moved vertically relative to the second handle and the cleaning pad.

The present disclosure relates to the field of smart home technologies, and proposes a base station and a cleaning robot system. The base station is configured to clean a cleaning system of a cleaning robot, and includes a base station body and a cleaning component. The base station body includes a cleaning groove, and the cleaning component is movably disposed on the base station body. The cleaning component includes a liquid outlet device, and cleaning liquid discharged by the liquid outlet device is configured to clean the cleaning system and enter the cleaning groove. After the cleaning component is positioned opposite to the cleaning system, the cleaning component moves, and the liquid outlet device moves along with the cleaning component. Then, the cleaning component can remove debris from the cleaning system. That is, the cleaning robot can realize automatic cleaning on the cleaning component.
