A dry cleaning system particularly suited for employing supercritical CO2 as the cleaning fluid consisting of a sealable cleaning vessel (10) containing a rotatable drum (110) adapted for holding soiled substrate, a cleaning fluid storage vessel (12), and a gas vaporizer vessel (11) for recycling used cleaning fluid is provided. The drum (110) is magnetically coupled to a motor (120) so that it can be rotated during the cleaning process. The system is adapted for automation which permits in- creased energy efficiency as the heating and cooling effect associated with CO2 gas condensation and expansion can be channeled to heat and cool various parts of the system.
