the US does not mandate spying with roombas -- wtf are you smoking?
China absolutely shares info with all of its national police services, intelligence services, and military. Depending on the company these PLA may literally own some / most / all of the organization.
I am not in the US or China, and on balance I am less worried about the Chinese blowing my house up, but don't pretend they're nice, or that they're your friend. I don't want them having my data any more than I want the NSA, Research & Analysis Wing, or the NK Reconnaissance General Bureau.
