An apparatus for cleaning the touch screen of any personal electronic device, including but not limited to smart phones and personal computing tablets. The apparatus comprises a wet portion and a dry portion in a substantially horizontal figure 8 configuration. The apparatus may also comprise a reservoir for storing a volume of conventional cleaning fluid. When not in use, the apparatus is slid into a case which is configured to house the wet and dry portions of the apparatus in separate housing compartments. A method is also provided for storing the apparatus when not in use so as to prolong its effective lifespan and improve its overall performance.

Methods and systems are provided for automatically maintaining cleanliness of an vehicle. In one embodiment, a method includes: receiving, by a processor, at least one sensor signal from a sensor that monitors for particulates within an interior of a vehicle; determining, by the processor, a level of uncleanliness of the vehicle based on the sensor signal; and selectively generating, by the processor, at least one of a control signal to a cleaning element of the vehicle and a notification message based on the determining to achieve the level of cleanliness.

A wiping device includes a rod, a spraying assembly, a base, and a translation module. The wiping paper is wound around the rod. The spraying assembly comprises a nozzle. The nozzle is arranged above the rod, and the nozzle is arranged towards the wiping paper. The base is used for fixing a workpiece. The translation module is coupled to the rod or the base. When the rod rotates around an axis of the rod, a wiping paper is wound around the rod. The nozzle could spray a cleaning agent to the wiping paper, then, the translation module could drive the rod and the base to move relatively, and the wiping paper wetted by the cleaning agent wipe the workpiece. The cleaning agent could wet the outermost layer of the wiping paper directly, so that the amount of the cleaning agent could be reduced.

A printing system cleaning fabric (13), having a first layer (131) with a first cleaning surface (131), and a second layer (132) with a second cleaning surface (1321) facing away therefrom. The first and second layers (131, 132) extend parallel to each other and have a respective inner surface (131, 132) attached to the other along an extension of the cleaning fabric (13). The first and second layers (131, 132) have different permeability characteristics.

A substrate cleaning apparatus that brings a cleaning tool into sliding contact with a substrate surface while rotating the substrate to perform scrub-cleaning includes a cleaning liquid supply unit that ejects cleaning liquid onto the surface of the substrate to perform a rinsing process of the substrate after scrub-cleaning, in which a temperature of the cleaning liquid in the rinsing process is set to 0 C. to 20 C. The cleaning liquid supply unit includes a first cleaning liquid supply unit that supplies the cleaning liquid toward the vicinity of the center of the substrate and a second cleaning liquid supply unit that supplies the cleaning liquid in a spray form toward a region between the center and an edge of the substrate, and a first ejection angle by the first cleaning liquid supply unit is smaller than a second ejection angle by the second cleaning liquid supply unit.

An autonomous solar collector cleaning device includes at least one main shaft, a first driver attached to a first end of the at least one main shaft, and a second driver attached to a second end of the at least one main shaft. The first and second drivers propel the cleaning device along a surface of the solar collector. A first sensor is attached to the first driver to detect an edge of the solar collector, and a second sensor is attached to the second driver to detect the edge of the solar collector. A control circuit maintains alignment of the cleaning device with respect to the solar collector based on outputs from the first and second sensors.

An apparatus for treating optical fibers can be used to carry out necessary cleaning work on the end tips of the glass fibers of fiber-optic cables. The apparatus has modules which are provided with non-abrasive surface layers able to pick up contaminants and are spring-mounted in relation to one another such that they can be pivoted about a hinge joint, and, in the case of at least one of the modules, elastic material layers are introduced between the surface layer and the main body of the assembly. The assemblies are preferably designed in the form of grip plates, between which non-abrasive, cloth-like layers are applied, as a cleaning surface, to each of the facing surfaces and, in the case of both gripping plates, elastic insulating materials are arranged between the cloth-like surface layer and the gripping plate.

A wind turbine including a rotatable part, at least one absorber element secured to the rotatable part within an interior of the wind turbine, the at least one absorber element at least partly comprising lubricant absorbing material, wherein the absorber element is configured to absorb emerging lubricant inside the wind turbine is provided. Further, a rotor hub for a wind turbine, an absorber element for a wind turbine and a method for maintaining a clean environment in a wind turbine is also provided.

A substrate cleaning apparatus includes outer circumference supporting members 32 that support the outer circumference of a rotating substrate W, a swing cleaning member 34 that swings between a first peripheral position B and a second peripheral position B of the substrate W while passing a center portion A of the substrate W to clean a front surface of the rotating substrate W, and an elongated supporting member 36 that extends long from a third peripheral position C to a fourth peripheral position C of the substrate W so as to pass the center portion A and supports the rear surface of the rotating substrate W. The first peripheral position B is disposed between a position D of the outer circumference supporting member 32 of the plurality of outer circumference supporting members 32 and closest to the third peripheral position C and the third peripheral position C.
