Get an industrial/commercial Roomba, and install those self-cleaning toilets "stalls".
Now that I think about it, Alex Haley's "Hotel", the book that is, has a staccato passage by a hotel chain executive on what he's going to do to the private hotel on the block.
He mentions redoing the floors in the rooms to automatically vacuum from underneath carpeting, reducing the labor to clean the rooms...
NJow THERE’S an idea.
