Full-size and fully featured, with the washer on the bottom and dryer on top, the LG WKGX201HBA Stacked Electric and Gas Laundry Center With 4.5 CuFt Washer & 7.4 CuFt Dryer takes up half the space, giving you room to add a sink, a folding table, or whatever you like. But unlike conventional stacked pairs, LG's exclusive Center Control™ panel is perfectly positioned with both washer and dryer controls at just the right height. Built-in intelligence makes laundry less of a chore by taking out the guesswork, while top-of-the-line innovations put advanced cleaning power within reach. Forget about sorting or choosing cycles- built-in sensors use AI technology to detect fabric texture & load size, then customize wash motions, dry temps & more for advanced fabric care. The Allergiene™ wash cycle uses the power of steam to remove common household allergens in fabrics by more than 95%.
