2. FEATURES & TECHNICAL EXPLANATION

2-1. FEATURES

The larger drum enables not only

ŽŒ™GŒˆ‹G‹™–—Gˆ•‹Gš›™–•ŽŒ™GŠŒ•›™œŽˆ“G–™ŠŒS

but also less tangling and wrinkling of the laundry. Heavier loads, such as king size
comforters, blankets, and curtains, can be washed.

The advanced brushless DC motor drives the drum directly, without belt or pulley

Tilted drum and extra large opening make it possible to load and unload clothing
more easily.

Steam washing features upgraded washing performance with low energy and water
consumption.

Automatically detects the load and optimizes the washing time.

The child lock prevents children from pressing any button to change the settings
during operation.
