Abstract
A dry type cleaning housing which causes a cleaning medium to fly with an air flow and places the cleaning medium on a cleaning object to clean the cleaning object is disclosed. The dry type cleaning housing includes an inner space which causes the cleaning medium to fly; an opening which abuts the cleaning medium against the cleaning object to collide the cleaning medium with the cleaning object; a ventilation path which passes air from outside into the inner space; a suction opening which suctions the air introduced into the inner space via the ventilation path to generate a revolving air flow in the inner space; a porous unit which passes removed matter removed from the cleaning object to the suction opening side; and a revolving air flow adjusting unit which arbitrarily reduces or stops the revolving air flow.
