Roomba and the likes are definitely robots. The advanced ones have cameras, map your floor, vaccuum clean, water clean, etc. You can contact them remotely (a friend uses her cleaning robot to spy on her husband while he's at home!) and give them orders.

Nobody ever said "robot" meant "machines with AGI thinking": robot, literally as defined by the person mentioned in TFA and who coined the term, meant "to work" / "forced labor". Work/labor that could be done by servants.

If cleaning my entire apartment by vaccuum cleaning, water cleaning, giving me reports about it, obeying my orders (e.g. if I tell to stop) ain't "automated labor that could have been done by a servant", I don't know what is.
