The mechanism of the scrubber is designed to collect surfaces cleaned by brushes and dirty water resulting from cleaning operations by the squeegee blade set and the suction system. This squeegee blade set should be such that it does not deform over time to create the ability to create suction and vacuum space for the suction engine. Rubbers of squeegee blade set are polyurethane which does not decay when exposed to water and moisture. Also, these rubbers should be soft enough to not prevent the scrubber from moving. These rubbers are anti-abrasive to prevent cracking during operation. The thickness of the rubbers is determined by the length of the blade. The greater the thickness of the rubber, the greater its resistance to tensile and wear pressure in the face of the earth's surface.
