Seriously, who cares about you or your house? Why do you think your personal example is the one to reason from?
iRobot sold 50 million robots, lets conservatively say 10% of those are internet connected and still in service. That's 5 million households. There's probably quite a few people in that 5 million who have something going on that Chinese intelligence is interested in, even things that may affect you personally, if indrectly (if that's what you care about).
