Persistent illusion
Vacuum and blow both create static, that's kind of the reason why compressed air is popular for cleaning out hardware.
It's an industrial vacuum with the motor electrostatically shielded. The motor in the vacuum cleaner is actually the largest generator of static. If you're concerned about the large movements of dust creating static in and of itself, consider that when you use compressed air, it is doing exactly the same thing anyway... Just be careful not to touch pc components with the end of the vacuum cleaner and it should be fine...
