Laundry bot would definitely make money, tons of it. Robo maid is like numero uno on things people have historically wished robots would do in the future
Before the invention of modern washing and drying machines, sure. But today many people in big cities don't even have an washer and dryer in their home or may not have one in the building, this problem spans many different use cases of how people consume the service. I'd consider asking things like:
* Is the barrier higher and value lower because they have laundry in their unit or does the value increase marginally because they have in the building, or is it more lucrative because they don't have laundry at all?
* And does a solution scale easily across these different use cases?
* The ability to provide continuity on even a pure software scale makes this a particularly pricey arena to enter because a person is required to fulfill this service. To find ways to make this economical, we'd have to consider co-opting existing behaviors or economic patterns. Are there _multiple_ existing patterns that we can enhance?
Yep, I paid around $2000 for a nice Hitachi drum-type washer-dryer machine last year.
I would certainly, without any hesitation whatsoever, have been willing to pay $5000 or even a bit more for one that, instead of just washing and drying all our clothes, took a pile of dirty clothes as input and output a few stacks of washed, dried, folded, and sorted clothes.
Anybody with children would want this; those who also have sufficient money would buy it.
