Can I surmise that most automation in dishwashing etc is geared for commercial enterprises ? I find the same lacking in a household. Sure you have the traditional dishwashers and vegetable choppers but they are largely clumsy to use and still take quite a lot of effort.

For a consumer, I don't know if the equation 'human labor cost << robots' holds true. It is a hassle to get human labor and there is no scope for time arbitrage. A robot can do the dishwashing job at night for example. Unlike a traditional dishwasher, you don't have to load the utensils. Just leave the utensils in a sink and you are done.
