I'd quite like to use it to clean dust out from electronic equipment.
From another vacuum cleaner (industrial photo-copier maintenance thing) I have a short conductive hose and various end tools, so I'm almost there; but I need to ground something - possibly the hose coupling to the cleaner.
Would that work? Or would the passing air circumvent it, and become charged anyway.
If so, I think I might need to make conductive and internally ground parts of the vacuum cleaner, using metal loaded paint and/or aluminium tape. Work that I want to avoid if possible.
