My understanding is that all of these endeavors involve scale and are very different from a drop-in replacement humanoid robot.

Like with the particular examples you sited, cleaning restrooms can have a huge number of "edge cases" which nothing short of a robot with human-like capabilities could handle.

If expenditures on AI is as huge as it is, with the financials being as shaky as they are, despite AI seeming to be very effective for very high paying jobs, I can't immagine the capex and shaky financials for replacing menial labor en mass. Like immagine all the chips, metals, compute needed as well as the maintenance, depreciation, vandalism, etc.
