A dry-cleaning process for cleaning articles disposed in a cleaning chamber having jet inflow ports, using carbon dioxide (CO2) from first and second storage tanks, the process including the steps of compressing gaseous CO2 into the first storage tank to cause a positive pressure differential between the first storage tank and the cleaning chamber, filling the cleaning chamber with liquid carbon dioxide by enabling CO2 flow from the first storage tank to the cleaning chamber in response to the positive pressure differential, alternately compressing gaseous CO2 into the first or second storage tanks to cause a pressure differential between the first and second storage tanks, and flowing liquid CO2 between the first and second storage tanks, via the jet ports and through the cleaning chamber, in response to the pressure differential between the first and second storage tanks, to provide jet agitation in the cleaning chamber and a periodically continuous flow of liquid CO2 through the cleaning chamber.
