Dyson DC59 Nozzle Adaptor for Vacuum Bags by ssaggers

Last crawled date: 3 years ago

This adaptor is designed to allow the Dyson DC59 (and similar) hand vacuum cleaner to be used to suction "space bags" (clothing storage bags). Since these vacuum cleaners have a protruding piece that stops the nozzle from sealing flush with the space bag nozzle, you can't get a proper seal without this piece.
I have uploaded two designs:
One is a basic nozzle with no special features, which can be used as a starting point for making other adaptors and vacuum tools.
The second has a restraining key (to stop the tool from rotating freely), vent holes (to allow a small amount of airflow, preventing the vacuum from pulsing as it senses low airflow), and a rotating vent cover (which allows you to adjust the amount of air flow passing)
I'd like to see if anyone else uses these as a basis for other vacuum cleaner attachments.
Side note: I didn't bother doing the experimentation required to properly size the vent holes (i.e. drill test holes in the non-vented attachment to see how big the hole had to be to prevent pulsing), so the two longer slots are larger than required.
Based on testing with the new model ("space bag attachment - with breather"), you need an orifice of about 75mm² area to allow sufficient air flow to prevent the dyson pulsing off due to low flow. this is equivalent to having the second smallest breather half-covered.
