I'd bet many more than a few years away from a robot that can arbitrarily navigate your house, gather laundry from several baskets, the floor, etc. Divide into whites/colors or warm/cold loads if desired. Load them into an arbitrary washer, measure out detergent, use the right washer settings for the given load. Then come back and move them to the dryer, then come back and unload, fold, put away, etc. And don't get me started on sheets.

It's much easier than it should be to fool people with demos.
