ABSTRACT:
This invention is a motor rotary device having a pump to enhance pressure of water passing through the interior compartment of the brush. The water, while flowing through a water pipe, is allowed to mix with fluid additive and then flow out from the center portion of the brush. There is a pump located at the water pipe. When the motor rotates in a certain direction, it will allow a moveable sliding shaft to slide to a certain position to move a set of idle gears and make the pump rotate to enhance the water pressure of water pipe's water.
