[0002] The escalator is composed of a chain conveyor with a special structure and two belt conveyors with a special structure. It has a circulating moving ladder path and is a fixed electric drive device for transporting passengers upward or downward between different floors of a building. In order to ensure the safety of pedestrians standing on the escalator, guardrails are set on both sides of the existing escalator. Since the handrails of the elevator are easily contaminated during use, it is necessary to clean the handrails of the elevator. Nowadays, when cleaning the handrails of the escalator, it is usually necessary to manually scrub the handrails regularly, resulting in a high labor cost. In the existing manual cleaning process, a cleaning rag needs to be used to fit the elevator handrail body. This has the disadvantage that the dust attached to the surface of the elevator handrail is difficult to wipe off completely due to the uneven fit of the rag, and the rag needs to be cleaned after use, which affects the cleaning efficiency of the elevator handrail.
