a dry-cleaning machine is similar to a combination of a domestic washing machine, and clothes dryer. garments are placed into a washing/extraction chamber (referred to as the basket, or drum). the chamber is the core of the machine. the washing chamber contains a horizontal, perforated drum that rotates within an outer shell. the shell holds the solvent while the rotating drum holds the clothing. the basket can hold between about 10 and 40 kg (20 to 80 lb).
