Systems and methods are provided for treating clothing with a clothing treatment device under a pressure environment altered from an ambient pressure. In one example, the clothing treatment device may comprise a chamber which may be evacuated to a low internal air pressure by a vacuum pump and/or a cold plate, wherein fabric articles placed inside the chamber may be washed and dried, and wherein the drying occurs under low pressure conditions within the chamber via one or more heat sources. In at least one example, the fabric articles may be hanging within the chamber.
