The device is inserted into a mesh hole of eachfiltering mesh by an insertion rod; sundries such as leaves attached on the outer wall of the filtering mesh are pushed outwards; through shrinkage of a spring, the right end of a shovel plate is closely adhered to the outer side wall of the filtering mesh, so the shovel plate can shovel off the sundries attached on the outer wall of the filtering mesh, blocking of the filtering mesh is avoided and thus working efficiency of the device is increased; and a part of water in the device enters an inner cavity of a cover body via a through hole, so heat dissipation of the motor is realized and thus working efficiency of the motor is increased.
