Why is cleaning a PC internals with a vacuum cleaner bad?

Hi all Yes, I've done what is in the title a dozen plus times in my life. I don't clean computers too often, but a new workstation means I am inclined to do so regularly. Once really fine dust settles, it's hard to get off! I saw the DataVac. £££/$$$!! I understand it's a bad idea due to static build up. But being UK-based, all of our large electronics are earthed and I wonder if static is discharging there, hence me having no fried hardware so far. Also, vacuuming seems a smarter move. Don't just blow the dust loose, but suck it up for disposal! Appreciate any advice on how I keep on top of dust build up!

It isn't bad if you're doing it right. You can destroy your pc with a blower too if you do it wrong. However, blowers are generally more powerful than suckers. They can blow out dust more effectively. Generally, you take your PC out in the garden or balcony or any other outdoors space, and then blow it through with the blower. Make sure to use electronics safe blower as it can shoot particles from the filter or motor into your parts, in case of motor dirt, it can also be conductive. That's why DataVac is so expensive (besides being totally US made). For a vacuum, just ensure you're not using bristles, as they are the ones creating static (not the suction on it's own).
