Easy to use, it can quickly and effectively remove dirt from floors, roofs, walls, desktops, and other surfaces. It is similar to a roller used for painting walls, consisting of a roller and a handle. However, the roller mentioned here is made of a sticky substance, and it can be torn off like a sticky dust pad to remove the soiled layer. When using it, simply roll it on the surface to be cleaned, just like painting a wall. When the roller becomes dirty and can no longer absorb dirt, simply tear off the soiled layer along the fold.
