I've done some 3rd world travel without washing machines for a while and my laundry was once a week dunk stuff in the sink for 5 minutes with shampoo + rinse water, wring and hang up. I don't buy the whole day being necessary thing.
Well, now we can own more clothes! And we can wash them more often! And rather than specialist washerwomen, everyone can/must use the laundry-room robots!
