Abstract
A dry-type cleaning chassis includes a chassis part including an opening part in contact with a cleaning target, an air inlet duct provided to blow external air into the internal space; a suction port provided for generating a circulating air flow in the internal space by suctioning air having been introduced into the internal space via the air inlet duct; a porous unit configured to pass objects removed from the cleaning target to a suction port side; and a path limiting member formed of a cylindrical shape extended in an axis center direction of the circulating air flow and configured so that an inside of the cylindrical shape is in communication with the suction port as a suction path.
