You should *never* use a vacuum cleaner inside a computer. If you do
so, you run the risk of a static electricity discharge frying the
motherboard.

Instead, blow out the dust with a can of compressed air.

A use the "plastic tube thingie" add-on comes with every vacumn cleaner
and I put on it's output nozzle (rather than suck) and if she's really
dusty take it outside cause it'll make a mess

I often wonder if I over-rev the fan(s) sometimes but I've never had one
fail after doing so. I also uplug it from AC.

Certainly true. And I recommend avoiding all levels that you can
readily avoid.


An air compressor is fine, but very few of us have one. So for all
practical purposes, canned air is what's best.

That would be fine if canned air worked, but in my view it doesn't. It
only dislodges a tiny fraction of what needs to be removed.


That's not my experience at all. Does it remove everything? No,
nothing will remove everything. But it removes the great majority of
what's there.

I agree in theory, but in practice I'm not nearly so strict. I've used
a vacuum cleaner well over a thousand times over the years and never

I think I have seen vacs specially designed for use with computers.
Expensive (overly so, I think), but presumably static-dissipative. I'm
talking about mains (US: line) powered ones, not the USB-powered mini
ones that are really just for cleaning the keyboard.


Yes, I've seen those too. How effective they are at eliminating
static, I don't know. But if you, or anyone else, could point me to a
web site that discusses their effectiveness, I'd like to read more
about it.

If they are effective, and not *too* expensive, I would consider
buying one. Do you remember what prices you saw?

That's ridiculous, considering the amount of risk we're talking about
here, which is about as close to zero as you can get. There's risk
with canned air, as well. Do you avoid that, too? Probably not.

If that's your experience, you'd probably be shocked at what it
DOESN'T remove. The loose dust bunnies are easily removed, but they
aren't the problem.

I routinely see systems where the CPU heat sink fins are packed
tightly with a combo of dust, cat hair, and who knows what else. That
stuff laughs at me when I reach for canned air. When it comes out,
it's in small chunks, almost cement-like.

My solution for packed hair ect is a small air nozzle on my air compressor.
done properly it does no damage and gets rid of the build up.

Try typing computer vacuum cleaners into Google. There are plenty and
plenty of reviews. The number things that can be most effective are
preventative. SHCS is the number one cause of congestive computer
buildup. Second hand cigarette smoke will cause that dust to stick.
Keep the air in the room as dust free by adding cheap solutions.

I use several of these that I made myself. Fan,filter,tape. I have
four running at all times in my computer room and can say they work
better then any commercial filter on the market.

What size and make is your compressor. I was thinking of attaching
connections to an air ball to use a nozzle. I'd have to cut off that
tire inflating end first obviously.

Thanks. I googled it yesterday, and found lots of ads and some
reviews. But what I had hoped to find and didn't find was an article
by an *expert*, not necessarily about any particular computer vacuum
cleaner, but discussing the effectiveness and risk (or lack or risk)
of using any such machine.

Fortunately there's no cigarette smoke in our house, second hand or
not. I stopped smoking 44 years ago, and we don't permit any guests to
smoke here.

I don't think it's all that complicated so I wouldn't hold my breath
looking for an "Expert". You could make your own and become an expert
yourself I love inventing little gadgets and such. You could mount
small plastic tubes at several points throughout your system and
connect a vacuum pump.

Same here. I don't quite remember just how many years it was for me
but I can say I never smoked in my adult life and I will be 65 in
July.

No, but I've had a quick look: the prices are even more eye-watering
than I remembered:

That has some .pdf files which might say something useful (I haven't
looked).

Vacuum cleaners are made for computer and other cleaning of even powered
up electronic equipment. The chief differences are carbon or another
semi conductive material added to the plastic, and spark suppression
capacitors on the brushes, as well as anti static bags.

Long ago, I got into a big hassle over this type of specialty vacuum
cleaners.
It had to do with (of all things) the paper bags. Seems that the GSA
rotated suppliers and wanted to substitute vacuum cleaners that were the
household type. When we finally got it through their heads that the
vacuum cleaners were special purpose, naturally the contract would be
expired, the order cancelled, and we'd have to start the process all
over again. We had something like ten thousand bags in inventory for the
original vacuum cleaners. (Antistatic bags, to boot!)

Finally, we had a stack of paper about a foot high documenting our
efforts, and a GSA exec wandered by on a tour, asking about problems.
Shortly after we showed the tour group the stack of paper, a dozen of
the correct vacuum cleaners showed up, current contract or not. We
didn't even get a bill!.

So yes, small shoulder carry vacuum cleaners suitable for computer use
are made. The price those days was almost twice that of a similar model
without the anti static and noise suppression options. About $100
instead of $59.95

It's those damn motors that run wide open all the time and generate
static and noise that I hate. The computer is nothing but a vacuum
cleaner with hardware stuffed inside.

I don't own a household vacuum cleaner that uses bags.Right or wrong
for some reason I figured the new bagless ones were better.

Probably not enough competition. There are countless numbers of HH

I've often seen ads for vacuum cleaners in which the seller proudly
states that they are bagless. I've never understood that pride. To me,
it seems that not having a bag that you can throw away with the
collected dirt means that emptying the vacuum cleaner is far dirtier
and more troublesome.

What am I missing?

I have an old "Green Machine" that is also a rug cleaner. It has been
working fine for what seems to be over 10 years. It has no bag and has
a large container that looks like it would hold more then any bag.
From what I remember the bag cleaners don't suck as much as the bag
gets full. It is a bit of a pain to empty but I do it out on my back
deck every few months or so. I've been waiting for it to die so I can
look into a newer model that might work better. You might be right
about the old style being more convenient.
