There are already cheap, domestic robots for cleaning dishes, cleaning the floor, cleaning clothes, making coffee, heating and cooling food, turning screws, drilling holes and so on. All those robots represent a greater than 90 percent (and sometimes a greater than 99 percent) savings in time relative to doing the same tasks manually. You still have to move the objects they operate on around within your house but that's mostly the only part of the task you have to do.
