The first category: vacuum suction cup adsorption
The double-layer vacuum sucker sucks the bottom air through the internal vacuum pump to form a certain vacuum environment, so that the window wiping robot can be adsorbed on the glass. This kind of adsorption principle has higher requirements on the medium and requires the glass surface to be flat and has no obvious Obstructions are raised and are limited to use on glass surfaces.
The second category: fan adsorption
The fan-mounted window-wiping robot passes the internal fan to form a pressure difference between inside and outside, so as to be adsorbed on the glass. This kind of adsorption principle has a slightly wider requirement for the medium, as long as the medium surface is flat (except for the glass surface, like a sticker). Glass, frosted glass, marble walls, tiles, etc. can be adsorbed).
