PURPOSE: A filter device washed automatically is provided to enhance a cleansing function and to eliminate a unit filter element surely by the rapid movement of cleansing water throughout upper part to lower part of the unit filter element. CONSTITUTION: The filter device washed automatically comprises a housing(10); an unit filter element(20); a unit filter drum(30); an upward washing rotating member(40); a downward washing rotating member(50); a drain valve(60); a cylinder member(70); a connection part(80); and a flux help rod. The fluid flows in passes through the unit filter element and it is filtered. Multiple unit filter elements are equipped according to a columnar direction. The unit filter drum surrounds the unit filter element. The upward washing rotating member is connected to the upper direction of a specifically selected unit filtering drum. The downward washing rotating member is connected to the lower direction of a specifically selected unit filtering drum. The cylinder member ejects and inhales fluids by the reciprocating motion of a piston(72). The connection part connects the cylinder and the upward washing rotating member. The upper direction washing rotating member is located in the unit filter drum of the specific any one. The fluid ejected from cylinder member is flown to the unit filter drum of the specific any one through the upper direction washing rotating member. The unit filter element of the specific any one is washed. Fluid is flowed out in after that through the drain valve. The flux help rod is equipped in the internal space of the unit filter element. Cross section of the flux help rod, it over the time gradually widens to downward.
