[0041] It also includes a pull rope 501; each cleaning box 401 inner wall is fixed with two left-right symmetrical pull ropes 501; each pull rope 501 is in contact with the bristles of an electric brush roller 402.

[0042] During the process of scrubbing the curved glass plate 004 with the cleaning cloth 103, the cleaning cloth 103 is cleaned by the cleaning component. Taking the working process of the cleaning component on the right as an example, when working, the two water sprayers 403 are connected to an external water pump through a conduit, and the water sprayers 403 spray water on both sides of the cleaning cloth 103 through the water spray port, and the two electric brush rollers 402 are controlled to start. Based on the view from the front to the back, the left electric brush roller 402 rotates clockwise, and the right electric brush roller 402 rotates counterclockwise. The two electric brush rollers 402 cooperate with the water sprayed by the two water sprayers 403 to clean both sides of the cleaning cloth 103, and the residual stains and water on the cleaning cloth 103 are scraped off by the two protective plates 404, and the two protective plates 404 are used to clean the cleaning cloth 103. The cloth 103 is protected to prevent splashing water from falling on the cleaning area of ​​the cleaning cloth 103. The waste water generated by cleaning is guided by the protective plate 404 and collected in the collecting box 405. The drain pipe 406 is connected to the waste water collection box through a conduit for unified collection. In the process of the rotation of the electric brush roller 402, the bristles of the electric brush roller 402 are moved by the pull rope 501, and the electric brush roller 402 is self-cleaned in coordination with the water sprayed by the sprinkler 403, so as to prevent the stains on the cleaning cloth 103 from adhering to the bristles of the electric brush roller 402, thereby ensuring the cleanliness of the electric brush roller 402, and then ensuring the cleaning effect of the electric brush roller 402 on the cleaning cloth 103, that is, ensuring the cleaning effect of the cleaning cloth 103 on the curved glass plate 004.
