High-efficiency (HE) laundry appliances utilize a wash plate or impeller at the bottom of the drum instead of a central agitator. This impeller rotates, gently lifting and tumbling clothes through the water to clean them. This differs from traditional top-load machines, which use a central post with fins or vanes to agitate clothing.
This impeller-based cleaning action offers several advantages. It typically uses less water and energy, leading to lower utility bills and reduced environmental impact. The gentler washing action can also extend the lifespan of clothing by reducing wear and tear. Furthermore, the absence of a central agitator creates more usable space within the drum, allowing for larger loads and bulkier items like comforters. The shift toward this technology reflects a broader trend in appliance design towards greater efficiency and fabric care.
