Does anyone use a vacuum with a small-diameter hose to vacuum dust and
debris out of electrical equipment? I have an HP power supply that
defies normal cleaning methods, and I am looking for a small 110V vacuum
cleaner that has a hose and nozzle that can get into reasonably tight
places. We used to use something similar to vacuum out toner from
non-impact printers, but I haven't had much finding anything on the web
except tiny little USB-powered keyboard vacs and the like.

Thanks,
