      Automatic scrubber is a kind of floor cleaning machine with different moving type of hand-push, ride on and full automatic. It works by two pivotal structures: brusher at front and intake system at back. When it works the brusher rotates automatically on the floor with the scrubbing solution outflow from solution tank, the force of friction from the brusher and the solution’s emulsification make the floor clean, meanwhile the intake system at back gathers the waste water left on floor and flow into the recovery tank. So with the scrubber moving the whole ground will become clean and dry. And to get better cleaning effect, the solution concentration should be changed according to different floor condition, and water should be in normal temperature, can’t be too cold or too hot, water over than 50°C is forbidden.
