"longDescription": "When sleek good looks meet powerful cleaning and intelligent performance, you’ll experience laundry on a whole new level. TurboWash 360° cleans larger loads fast so you get more done while enjoying the same great washing performance. And forget about endless sorting—AI technology uses built-in sensors to detect fabric texture and load size and then automatically selects the right settings for advanced fabric care. Activate Smart Pairing in the ThinQ app, and the washer can even tell the dryer to select a compatible drying cycle, making it the ultimate laundry hack. The gentle power of steam reduces common household allergens in fabrics by more than 95%*. Durable and stylish tempered glass door with rose gold accents adds the perfect finish. *Based on certification by the Asthma and Allergy Foundation of America (AAFA)",
