With the ability for machine learning to recognize your dishes, cutlery and paper trash, a robot arm could pick up these objects while a pressure washer of hot water sprays and dries. Wrap this up in a box with a conveyor belt on the front and half the battle is done. Putting the dishes back in the cupboard is another matter. It seems like a robot would be easier to build than a big box that somehow integrates with existing cabinets and drawers.
