This vertical countertop dishwasher saves space in the kitchen. It features a split water tank design. The main body of the dishwasher is separated from the water tank, reducing the volume of the main appliance by about 30%. The water tank should be positioned next to the sink so that users don't have to continually add water and it can easily be moved, to adapt to different kitchen layouts. The telescopic water tank structure reduces the space it occupies. The dishwasher also features a folding door design which means that the door does not exceed the table so that users do not need to avoid the door.
