Washing machine

A household or commercial appliance that cleans textiles by moving them through water and detergent, then rinsing them. Most models also extract water by spinning.

Agitator: A rotating or oscillating device that moves laundry through wash water in some washing machines. Top-loading machines use it to generate friction and circulation among garments.
Front-loading washing machine: A washing machine whose drum is loaded through a door on its front. Its horizontal-axis drum tumbles laundry rather than relying on a central agitator.
Scrub board: A ridged board used to rub dirt from wet clothing during hand washing. It represents the manual labor that early washing machines began to mechanize.
Laundry: The washing and care of clothing and other textiles. Washing machines mechanize the washing stage of this broader household task.
Microfiber: A very fine synthetic or natural fiber, often shed from textiles during use and washing. Machine washing can release textile fibers into wastewater.
Impeller: A low-profile rotating component that circulates water and laundry in some washing machines. It moves clothes without the tall central post found in agitator models.
Top-loading washing machine: A washing machine loaded through an opening on its top. This design often uses an agitator or impeller and allows loading from above.
James King (inventor): An American inventor who patented an early hand-powered washing machine in 1851. His design used a drum, an early step toward later machine washers.
Laundry detergent: A formulated cleaning product designed for washing clothes and textiles. Its composition must work with machine water temperatures, agitation, and rinsing.
Microplastic pollution: Environmental contamination by plastic particles smaller than five millimeters. Synthetic fibers shed during washing can contribute to this pollution.
