[0002] Floor scrubbers are also called floor cleaning machines, floor scrubbers and dryers or floor washing vehicles. They are used to clean hard floors. At the same time, they can suck up sewage through a suction shovel and take the sewage away from the site. They are suitable for stations, docks, airports, workshops, warehouses, schools, hospitals, restaurants, stores and other places with wide hard floors. As a modern and efficient cleaning equipment, floor scrubbers are widely used in floor cleaning work in various public places, commercial facilities, industrial workshops and home environments. Its efficient working principle mainly relies on the high-speed rotation of the brush disc to generate friction with the ground, thereby achieving effective removal and polishing of various stains.
