More economical by Intelligent Wash System
Intelligent Wash System detects the amount of load and water
temperature, and then determines the optimum water level and
washing time to minimize energy and water consumption.
Direct Drive system
The advanced Brushless DC motor rotates the Drum directly
without belt and pulley.
Child-Lock
