> You don't need flawless to empty a dishwasher

That really depends on how demanding you are. For example, I prefer to thoroughly wipe the dishes after taking them out of the dishwasher (if necessary). This is a fairly demanding task in terms of motor skills. I suppose we all have similar discrepancies from what is considered normal or good enough.

I mean, I sorta do need that. If a dishwasher-emptying robot drops my favourite tea mug while doing it, that will be quite a significant negative against it.
