Abstract
A dry-cleaning system operable for selectively controlling agitation of items during cleaning, rinsing, and draining cycles. The dry-cleaning system includes a pressure vessel for containing a liquid gas dry-cleaning solvent and a rotary basket disposed within the vessel for containing items to be cleaned. Controlled agitation is achieved by the combination of (1) driving the basket by a directional, variable speed motor and (2) a simultaneously selectively operable gas jet system having a plurality of nozzles rotatable with the basket for directing pressurized jet streams into the liquid wash bath.
