Suck or Blow?

I'd like a device to clean the dust and debris from PCBs and internals of appliances; eg PC, VCR etc.

Is it best to use a compressed can that BLOWS?

Is it better to invest in a more expensive electric blower?

OR

Is it better to use a handheld vacuum cleaner that SUCKS up the dust and debris?

unfortunately, you may need both.

There is a micro cleaning attachment set available for shop vacs etc.
If your going to vacuum toner a lot use a vacuum with a HEPA filter.

It makes more sense to vacuum and not dust, but it isn't always possible.

Canned air is very useful. A compressor may spurt out oil unless it's a diaphragm compressor. If it has a tank, it might spurt out water.

You really want to contain the dust, not spread it about.

As above, you will need both.

My only extra advice is some small soft paint brushes to aid in dislodging dust from cracks and crevices and if at all possible, when blowing dust out of something - do it outside.

Use compressed air and 90% of the time, that is enough. If not, try vacuum.

I favour a vacuum and a brush.
Compressed air blows the dust all over the workshop.

Get a longer hose for the compressor and step outside.

A vacuum cleaner and soft brush are the standard equipment for service departments, we never ever had a can of compressed air - you want to remove the dust, not spread it round.

That's why you use a compressor and not a wimpy little can. Beside, the cans are a liquified compressed gas that makes surfaces cold and can cause condensation in the dust which makes the dust adhere more strongly.
The compressor will definitely spread the dust round - mostly into your neighbors yard.

Anyone recommend a suitable vacuum cleaner?
Henry's are pretty decent - basically a motor on a bucket - they work well, and are exceptionally reliable (which is why many hotels and professional cleaners use them). They also have nice big bags and hold a lot.

Years back Vax were the one to go for (very similar to a Henry really), but they went bust a VERY long time ago - the new reborn Vax is a completely different company, and just reuses the old name.
