         20 . The filter cleaning device according to  claim 16 , further comprising:
 a first rotatable separation roller extending parallel to the axis of rotation of the brush and disposed upstream of the first comb-shaped member in the first rotating direction; and   a second rotatable separation roller extending parallel to the axis of rotation of the brush and disposed upstream of the second comb-shaped member in the second rotating direction.   
     
     
         21 . The filter cleaning device according to  claim 20 , wherein the first separation roller rotates in a direction opposite to the first rotating direction, and the second separation roller rotates in a direction opposite to the second rotating direction. 
     
     
         22 . The filter cleaning device according to  claim 20 , wherein the first and second separation roller are driven by the motor. 
     
     
         23 . The filter cleaning device according to  claim 16 , wherein the brush is reciprocally and translationally movable along the filter surface. 
     
     
         24 . The filter cleaning device according to  claim 23 , wherein the motor rotates the brush in a movement direction of the brush along the filter surface. 
     
     
         25 . The filter cleaning device according to  claim 16 , further comprising a dust box that receives the particulate matter removed from the filter by the brush. 
     
     
         26 . The filter cleaning device according to  claim 16 , wherein the brush comprises a body and a plurality of bristles radially extending from the body. 
     
     
         27 . The filter cleaning device according to  claim 16 , further comprising:
 a third comb-shaped member engaged with the brush; and   a fourth comb-shaped member engaged with the brush, wherein   the third and fourth comb-shaped members each have a length direction parallel to the axis of rotation of the brush and parallel to a width direction of the third and fourth comb-shaped members, respectively.   
     
     
         28 . The filter cleaning device according to  claim 27 , wherein the third comb-shaped member is directed toward the first comb-shaped member and the fourth comb-shaped member is directed toward the second comb-shaped member. 
     
     
         29 . The filter cleaning device according to  claim 27 , wherein the third comb-shaped member is inclined toward the axis of rotation of the brush in the first rotating direction, and the fourth comb-shaped member is inclined toward the axis of rotation of the brush in the second rotating direction. 
     
     
         30 . An air conditioner comprises a filter cleaning device according to  claim 16 .
