A robotic vacuum is one of those "simple" problems (the earliest roombas weren't even really "smart" at all, they just drove in a random walk pattern and assumed they'd eventually get all the floor).

A robot that can pick up a shirt from the floor and fold it and put it away is one of those "almost impossibly hard" problems.

I suppose something like that may exist, but if you can afford the millions of dollars it would cost, you can just hire a maid/cleaning service once a day.
