I saw a little rechargeable mini vacuum someplace (Costco I think). It wasn't much bigger than an electric toothbrush and had several brush attachments. I think it would be great for radios, getting sanding dust out of airframes and stuff like that if it actually works.
I've tried these.
Avoid them.
The vacuum is VERY weak, and unable to lift anything.
A shop vac with a brush attachment, and/or holding the vac nozzle over the area you are working on does a much better job...
