If my robot folds my laundry correctly for 99 days and on the 100th day shreds my wardrobe, I don't think that will print money (at least not for very long).
Unless I’m missing something?
The error domain of a laundry robot would be misidentifying an unusual item and incorrectly folding it, or incorrectly sorting it. If someone sold a humanoid laundry robot which folded and sorted my clothes correctly 99% of the time, I'd consider that miraculous.
Then a hard reboot will kick it back into line and we're good to go again.
Obviously that's not good enough for driving a car, but it certainly is in all the manual labor jobs I've ever had.
