No, not cleaning the computer, but on the floor near the desk the

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

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.
