A washing machine is a device that cleans clothes automatically using water, soap, and mechanical action. Instead of scrubbing each shirt and pair of pants by hand in a washtub (the way people did for thousands of years), you load your dirty clothes into the machine, add detergent, press a button, and let it do the work.

Inside, the machine fills with water and spins the clothes around, agitating them so the soap can lift out dirt and stains. After washing, it drains the soapy water and refills with clean water to rinse away the suds. Finally, it spins the drum very fast to squeeze out most of the water, leaving clothes damp but not dripping wet.

The washing machine revolutionized household work when it became common in the mid-1900s. Before washing machines, doing laundry was exhausting, all-day labor that involved hauling heavy buckets of water, scrubbing clothes on washboards until your knuckles were raw, and wringing everything out by hand. What once took an entire day now takes less than an hour of hands-on effort. This invention gave people (especially women, who traditionally did most household laundry) time for education, careers, hobbies, and rest, fundamentally changing how families lived and worked.
