If you're cleaning (or cooling) a laptop with a vacuum cleaner without
opening the case, then static is irrelevant. On a nylon carpet, you
are the biggest source of static whenever you walk across and touch
the casing.
OTOH if you open the case (laptop or otherwise), best keep vacuum
hoses away, for the same reason you can't vacuum a tablecloth with a
hose attachment.

Far better, even if it's your own breath (with care). Compressed air
can blow the dust out from a distance, whereas a vacuum hose only
works close to. I would only vacuum components that have a grille,
like the PSU.

I've never bothered with these. I just rest my wrist on the chassis
when it matters. (But I do wear cotton shirts.)
