The roller 100A and the wiper 100B are pushed and pulled to form an opening and closing state between the cleaning roller 100A and the wiper 100B, so that the wall surface can be subjected to roller cleaning as needed, and the wiper can be freely converted. At the same time, in order to better use and reduce the push-pull resistance, we also designed a lifting shaft 101. The lifting shaft 101 is fixed on the slider 100 in the middle, and the linear bearing and the lifting shaft are mounted on the corresponding cleaning roller 100A and the wiper 100B. The sleeves are respectively sleeved on the linear bearings. Thereby reducing the resistance of the electromagnet to push and pull.

Of course, we can also integrate the cleaning roller 100A and the slider 100 as needed. Reduce the use of two electromagnets 103.
