None of this really contradicts my points. Reduce the time spent cleaning by reducing the amount of time you spend cleaning. This could mean cleaning more often, but you will still spend less time doing it.

And... none of the people you mentioned are likely to benefit from the first several waves of robots cleaning outfits. Which was what I had on my mind.

That is, if you are a person that feels they need help cleaning their clothes, you are likely not a person that will benefit from the first robotic solutions. Unless, of course, you could already benefit from the current outsourcing techniques for the job. And it will be a while before those are beaten in price.

I say this as someone that has grown to love our robotic vacuum. Things is awesome. Probably still cheaper and more effective to just sweep and vacuum manually.
