A washing machine (laundry machine, clothes washer, or washer) is a home appliance used to wash laundry. The term is mostly applied to machines that use water as opposed to dry cleaning (which uses alternative cleaning fluids and is performed by specialist businesses) or ultrasonic cleaners. The user adds laundry detergent, which is sold in liquid or powder form, to the wash water.
Many people worldwide wash clothes manually, but the detergents are chemically harmful, and the repetitive motion of scrubbing is straining to the muscles and joints.
