Cleaning Computers Safely: Why Household Vacuums are a No-Go

Is it safe to pull out the household vacuum cleaner to clean the inside of your computer?

No, it’s not!

I would avoid using the typical household vacuum cleaner to get the dust out of the computer and other electronics. These vacuum cleaners can create static that can quickly destroy the electrical components of a computer.

Plus, it always seems to me that no matter how powerful a vacuum is it can never fully get the dust off the motherboard. The dust bunnies come off but its like there is fine dust that sticks to the components and won’t let go unless you blow them off.

There are better options to dust your computer, and we will talk about them in this post.

You shouldn’t vacuum the inside of your computer, but it’s fine to vacuum near your computer. 

How To Clean Your Computer Video

Here is a great video showing you how to clean your computer. Be sure to look below for even more advice and items that make cleaning your computer easy and safe!

What To Use Instead

What you want to use instead of a household vacuum cleaner is a blower. You can get cans of dusters like these here* just about anywhere. They work fine for the guy looking to dust every so often.

The problem with using Canned Dusters is that they don’t last long and lose power quickly. Plus, the Canned Dusters are not as powerful as the Electric Computer Dusters.

You can get electric computer dusters like this one here* that work far better than the canned ones. This is the better option because you won’t have to keep buying canned dusters every time you need to dust.

Make sure to dust the computer outside to avoid putting the dust back inside the home.

An Even Better Option

You should not use a household vacuum cleaner when cleaning a PC, but there is a vacuum cleaner made for cleaning computers that you can use.

The Metro Vacuum MDV-1BA DataVac Pro 4.5-AMP Computer Vac/Blower* is probably the best thing to use to clean a computer or any electrical component of dust. This vacuum sucks the dust in, but it also is a very strong blower that works well to get that fine dust off the electronics of the computer.

Why Can’t I Use My House Vacuum Cleaner?

Modern vacuum cleaners you use for your floors don’t have PC cleaning in mind when they build them. They don’t care about the static electricity that the dust and the plastic create as there is nothing on your floors that can be harmed by it.

The static charge it builds is small, but it only takes a small charge to destroy the sensitive CMOS or TTL components of a computer. With computers costing $1,000’s of dollars do you really want to risk killing it because you used a big household vacuum cleaner?

Keyboard And Accessories

I still would not use a household vacuum cleaner on the keyword or even the mouse. If you have crumbs stuck under your keyboard, you run the risk of accidentally sucking up keys especially if it’s a laptop keyboard when using a vacuum cleaner.

Instead, it would be better to blow those items out with the mentioned blowers above.

Other Things You Can Do

If you don’t want to clean your computer all the time you can pick up some dust case filters like these here* that will greatly help with the dust problem. If you don’t have the dust coming in, then you don’t have much to clean up.

It’s a good thing to keep dust out of a computer as some dust particles can become conductive and short out components of your computer.
