However, whether it is a double barrel or a single barrel, it is difficult to clean. During the cleaning process, because of the resistance of water, it is much more difficult to rotate the mop than to dry it. So everyone adds a gear reduction mechanism to the mop bucket or mop head to reduce the effort during cleaning. However, the structure of this method is complicated and complicated, and the cost is high, because the gear and the gear are matched with high precision, and the gears are easily attached by the dirt and cause the mechanism to fail.
