Know before you buy
The washer uses built-in sensors to detect the weight and texture of your clothes. It then automatically adjusts the wash motion, temperature, and cycle time to ensure the best cleaning performance while protecting your fabrics.
Yes, the 5.8 cu. ft. capacity is specifically designed to handle bulky items like king-size bedding, heavy towels, and large comforters without overcrowding the drum.
You simply fill the reservoir with detergent once, and the machine automatically dispenses the precise amount needed for each load. It holds enough detergent for up to 36 cycles, saving you from measuring before every wash.
TurboWash 360° uses multiple spray nozzles to deliver powerful cleaning jets from different angles. This allows you to complete a thorough wash of large loads in under 30 minutes without sacrificing cleaning quality.
The interface is designed to be intuitive, functioning much like a smartphone. It provides clear, step-by-step guidance for selecting cycles and customizing your wash settings.
The app allows you to start or stop cycles remotely, monitor your energy usage, and receive notifications when a cycle is finished. It also provides smart diagnostics to help troubleshoot issues quickly.
Yes, if you purchase the optional SideKick pedestal washer, you can install it beneath the main unit. This allows you to wash a small, delicate load in the pedestal while the main washer handles a larger load simultaneously.
