I have designed am attachment for a vacuum cleaner that could be really useful whilst cleaning the innards of a computer. Obviously brush attachments a a big no no due to static and so traditionally compressed air is used however this must be done outside (not so handy mid winter).
My design merges both of the above in that it fires a jet of air to lift the dust and suction from a vacuum cleaner to collect it. There are inly two moving parts in the design and all power is provided by the suction of a standard vacuum cleaner.The concept can be seen here: click here
I would appreciate any feedback. Would you use it? Are there any design flaws? Should I include any other features? How should it look?
