  What is common to conventional cleaning apparatuses is that spray water or compressed air is sprayed on one side of the filter, or a dust collector is disposed on one side of the filter to absorb the dust. This configuration is based on the structure of the roll filter in which dust or the like is adsorbed on one side of the roll filter.

  However, if the used roll filter is replaced in a wound state, the used roll filter is pressed against the other side by dust or the like attached to one side. There is dust on both sides. In this state, if cleaning water, compressed air, etc. are sprayed from one surface, the dust adhering to the surface to be wiped will be pushed into the inside of the filter, making subsequent removal difficult. It was. In particular, fibrous dust such as cotton dust, iron powder, and the like have been extremely difficult to remove when entangled inside the filter.

  In addition, when the filter is immersed in a cleaning solution or the like with dust or the like attached thereto, the absorbed cotton dust is easily entangled with the filter. If compressed air or a cleaning liquid is sprayed in this state, the entangled cotton dust further entangles with the deep part of the filter, so that it is difficult to remove the dust by subsequent brushing or suction.

  As described above, in the conventional cleaning device, since the cleaning is performed from one side of the roll filter, the cotton dust adhering to the surface to which the cleaning water or compressed air is sprayed becomes entangled and difficult to be removed. It has been difficult to efficiently remove dust and the like.
