Default Vacuum cleaners and computers

No, not cleaning the computer, but on the floor near the desk the computer
sits on. How far? About three or four feet to avoid damage to the HD
contents?

TIA

You can vacuum near the computer, it will not hurt it.

What do you think it will do to the drives? This is not the "magnet"
thing is it?

The case is grounded using a 3-wire cord to a properly grounded outlet,
right? Is the case (the outside shield) made of plastic or metal (so it
can actually be grounded)?

Unless you are using a handheld vacuum where the motor and pickup are
very close (although the motor size is tiny), the motor for a
push-around or canister vacuum isn't near the computer. If the case is
metal then no worries about the motor's magnetic field (which should be
mostly contained inside its metal housing) plus the metal case for the
HDD is also ground through the PSU to the cord to the outlet.

It's the pickup end of the vacuum that produces static electricity due
to the friction of impacting debris. The beater brush will also
generate static electricity. During winter or anytime when humidity is
low, you'll be shocking the case when you touch it. If it is metal
(sheet metal or foiled plastic) and properly grounded then the shocks
should get grounded. You touching the computer's case will incur more
shock events then for your vacuum cleaner's pickup end. I've seen where
a large static charge on a person that shocked a case caused the
computer to shutdown but have yet to see vacuuming around a case to
incur any effect.

My comps have always been on the floor without front and back covers and
I have always vac'd around them. Always with the comp power off though
because sometimes the vac bumps it pretty hard.
I use the air compressor to clean the insides.

Hopefully that would be an *oilless* air compressor.

I'm thinking of the electric field generated by the vacuum cleaner motor.


That is an old wives tale. Think about a floppy. You are erasing and
writing on one side of a diskette while the data is safe about .005"
away on the other side, only protected by mylar.
A magnetic field strong enough to penetrate the case of a computer or
even the case of the drive, would be pulling the knives out of the
drawer from the kitchen. They run MRI machines with PCs, sitting right
next to them. I would not even worry about the RF from the brushes.
The power supply in the PC is the one that needs a line filter, to
keep RF in, not out.

It's a 3 hp with both oiler for my air tools
and deoiler for the paint sprayer, via valve setting.
