If we had automated systems capable of even Level 1 it would completely change the nature of our economy. Forget it being a thing you buy, such a robot is replacing most manual labor.

Beyond that, tons of individual AI's housed in discrete, humanoid bodies isn't really a great design for a lot of reasons, and doesn't really reflect a realistic use of this tech in my opinion. And AI capable of your Level 2/3 tasks would already be changing the fabric of how our world works. In your hypothetical about staffing, it'd be more like having a distributed system for the building that operates all of the local units.

Otherwise, this would be something incredibly expensive. Like only bought by the wealthy and some upper-middle class. Like $50k-500k+ at the very least (just look at how much it costs to get one of those robot-arm camera operators, for instance). For everyone else it would be something they'd interact with as a service, like an app where you can hire a cleaning service, fast food workers, or the robot that picks up the trash.
