In your description there’s indeed a big difference. But I’m pretty sure Alicorn hadn’t intended such a superRoomba. As I understood her comment, she imagined a betterRoomba with, say, an extra sensor measuring force applied to its wheels. When it’s in the air, it gets input from the sensor saying ‘no force’, and the betterRoomba stops trying to move. This doesn’t imply beliefs & desires.
Since we can imagine a continuous sequence of ever-better-Roombas, the notion of “has beliefs and values” seems to be a continuous one, rather than a discrete yes/no issue.
