The Whirlpool Duet Series of Laundry is all about un-compromised fabric care and advanced efficiency. This video discusses the WFW9250 () washer and the WEDWGD9270 electric and gas dryers. New to the washer is TumbleFresh - a feature that continues to move the clothing around even after the cycle is done to avoid the build up of odor causing bacteria. The clothes dryers feature an integrated dryer rack and an eco-normal cycle that saves energy.
