I’m imagining a rented, non-deterministic dishwasher that only gets some things clean some of the time, and occasionally makes things dirtier.

- You can rent three of them and once the first one is done you can move the dishes to the second one, and so on.
- You can then also buy two more sets of crockery/cutlery and use whichever comes out cleanest.

But as long as you keep renting them, washing up is dead!!
