High-efficiency top-load laundry appliances utilize an impeller, a low-profile cone or disc, rather than a central agitator, to create dynamic water movement that lifts and tumbles clothes. This design contrasts with traditional top-load machines featuring a central post that twists back and forth to agitate laundry.
Impeller washing machines offer several advantages. They typically use less water, reducing utility costs and environmental impact. Their larger wash baskets accommodate bulkier items like comforters. The absence of a central agitator creates a gentler washing action, potentially reducing wear and tear on fabrics. This shift in washing machine technology reflects a broader trend towards increased efficiency and sustainability in home appliances.
