3 . Product Features Whirling washing tub * The laundry becomes cleaner than ever since the laundry is turned over in the whirling tub and washed by the beating of the higher whirling embossing on the tub. Washing by the strike of the strong falls * The strong falls vigorously strike the full load of laundry or the large laundry to clean. The light bedding is pressed even for the old dirt to be thoroughly removed. No detergent remnants in the detergent and the softener dispensers. * The powder detergent is solved to the liquid detergent in order to prevent the contamination of the environment. * If the softener is put in the dispenser, it is automatically flushed during the rinsing cycle. Softener Compartment Detergent Compartment Leveling feet * Since the leveling feet are on the front, it is convenient to adjust by hand. Large filtering net * Since the lint or other substances are thoroughly collected by the filtering net that is more than times larger than the existing one, you can feel the difference by the far cleaner laundry. Water spouting washing hands * The water spouting washing hands shoot up the water columns in the water to prevent the laundry from being entangled. The water columns shot up by the water spouting washing hands prevent the laundry from being entangled in substituted for the rod and they wash the laundry by scrubbing, which is the merit of the revolving board washer, as well. As a result, the cleaning ability is also excellent. Wider variety of rinse selection * By adding the rinse selection button, during the rinsing cycle, not only water is supplied, but also water can be added to the higher water level than that of the washing cycle and so on. Consequently, you have more choices to select the rinsing mode. SAMSUNG ELECTRONICS CO., LTD
