The mechanical turk, the robot maids of the 70s, etc.

Yes.

But I'm a little sad that I still can't buy a robot maid or butler.

I figured they would exist by now, for about the price of a vacuum.

I'm not demanding that they actually be any good. We could just program them to quote "The Jetsons" and do some simple vacuum pathing, or deliver a tray full of drinks.
