When the suction unit 700 is operated to suck the foreign matter and provides a predetermined suction pressure, the pressure distributor 630 may be configured to suck the foreign matter collected in the collecting unit 620 sufficiently And distributes the suction pressure of the suction unit 700 to the collecting unit 620. The collecting part 620 is a part where the foreign matter separated from the filter 400 and collected directly is collected and formed, and an opening 621 having an open upper part is formed so that the foreign matter can be easily seated. Here, the pressure distributor 630 and the collecting unit 620 are divided in the vertical direction (Z direction) so as to communicate with each other. A portion of the brush 610 that contacts the filter 400 is made of a flexible material and is elastically deformed while being in contact with the filter 400 and is restored to the original shape when the filter 400 is released from contact with the filter 400. [ ≪ / RTI >

As described above, the brush assembly 600 is moved to one side of the filter housing 500 while separating and collecting foreign matter filtered by the filter 400 while moving along the filter housing 500, Unit 700 as shown in Fig. Here, when the brush assembly 600 separates the foreign substances filtered by the filter 400 along the filter housing 500, some of the foreign substances may be attached to the brush 610.

When the brush assembly 600 moves to one side of the filter housing 500, the brush 610 may move to the side of the filter housing 500 when the foreign substance adheres to the brush 610, It is necessary to separately separate the foreign substances adhered to the surface of the substrate. The brush housing 610 is provided with a protruding portion protruding from a side of the filter housing 500 on which the brush 610 is disposed so as to separate the foreign substances adhered from the brush 610, And a flow guide part 520 protruding from the side of the protrusion part 510 where the brush 610 is disposed.
