Chinese vacuum is:
- Taking X-rated pictures of everyone in the house
- Accumulating possible blackmail material
- Listening in on conversations for technical information. Chinese intel would know which vacuums are owned by CEOs etc.
I would be worried if it started following me around and hides under the coffee table whenever I look at it. LOL
I suspect that a lot of that was known to the user. The Communist Party in China sends agents out around the world. No need to install software on their phones or computers which might be detected and be impossible to explain. Instead, instruct the agents to buy one of these vacuums and communicate back through it.
The vacuums are likely capable of two-way communications.
...and the Communist government of China is not the only government using such household appliances to communicate with their agents around the world.
