A cleaning system for a solar panel is provided. The cleaning system comprises: i) a frame moveable in a transverse direction over the solar panel, the frame having edges oriented in the transverse direction; a brush assembly positioned within the frame and moveable in a longitudinal direction including a plurality brush holders arranged within the frame, with each brush holder being adapted to interchangeably receive a brush for cleaning the solar panel; and a liquid spray arrangement including nozzles arranged one or more rows for spraying at least one of water and a water detergent mix onto the solar panel. The liquid spray arrangement includes nozzles positioned near at least one of the transverse edges of the frame for spraying the water detergent mix onto a longitudinal end of the brush assembly.

A cleaning pad can be attached onto an inner surface of a transport belt so the cleaning pad can move with the transport belt along hardware of a marking system, including support rollers and a marking platen to remove ink from the marking platen and support rollers of the rendering device as the transport belt cycles through its typical path within the rendering system.

A liquid knife cleaning apparatus and a liquid knife are provided. The liquid knife cleaning apparatus includes: a frame configured to be arranged on the liquid knife and be capable of reciprocating in an extending direction of the knife edge; a cleaning blade configured to extend into the knife edge of the liquid knife and be capable of reciprocating inside the knife edge under the driving of the frame to clean the knife edge, the cleaning blade being arranged on the frame; and a movable mechanism configured to control the frame to reciprocate on the liquid knife in the extending direction of the knife edge, the frame being connected to the movable mechanism.

A parasitic cleaning system for cleaning the reflective surfaces of a heliostat is disclosed. The system includes a blade carriage assembly that cleans the surface by imparting a frictional force as the carriage assembly moves across the surface to be cleaned. A cleaner drive system controls the motion of the blade carriage assembly over the surface. A guide system connects the cleaner drive system to the blade carriage assembly. The cleaner drive system applies a spring force to move the blade carriage assembly upwardly. The same spring system controls the lowering of the blade assembly over the surface to be cleaned.

The cable cleaning and rolling system combines an automated cleaning and winding system for industrial cables and the like with a water filtration system for recycling the water used to clean the cable. The cable cleaning and rolling system includes a hollow base, a feed drum and a receiving drum. The feed drum is adapted for releasably retaining and feeding the cable to be cleaned, and the receiving drum is adapted for receiving and robing the cable after it has been cleaned and dried. At least one nozzle, for spraying cleaning water on the cable, at least one brush, for scrubbing the cable, and a blower, for drying the cable, are positioned between the feed drum and the receiving drum.
