Front-loading washing machines use the tumbling method for washing clothes. In this method, the drum rotates horizontally, lifting the clothes and then letting them drop back down into the water and detergent mixture. This gentle tumbling action effectively cleans clothes while reducing wear and tear.
Why other options are incorrect:
(B) Agitation: This is used in top-loading machines with a central agitator that moves clothes vigorously.
(C) Spinning: Refers to the high-speed rotation used to remove water after washing and rinsing, not the washing method.
(D) Pulsation: A method used in some top-loaders where a pulsator plate moves water to clean clothes.
