ABSTRACT:
A dry type cleaning technology is disclosed. Dust adhering to a cleaning object is removed with a cleaning medium caused to flow by a high-speed airflow. The removed dust is separated from the cleaning medium with a porous member including holes through which air, dust, and granular material can pass but the cleaning medium cannot pass. An area on the porous member where air is received to cause the cleaning medium to flow and an area on the porous member where air is received to suction the dust separated from the cleaning medium are switched.
