Front-loading washing machines employ a tumbling process for garment cleaning. This involves horizontal drum rotation, where clothes are lifted and then fall back into the water and detergent solution. This mild tumbling action efficiently cleans clothes while minimizing damage.Rationale for excluding other methods:
(B) Agitation: Characteristic of top-loading machines, this method uses a central agitator for vigorous garment movement.
(C) Spinning: This refers to the high-speed rotation employed post-wash for water extraction, not the cleaning mechanism itself.
(D) Pulsation: A technique found in certain top-loaders, utilizing a pulsator plate to circulate water for cleaning.
