Shop-vac filter - always clean

Um, I know I’m not too smart sometimes, but how does “R2D2” suck the dust into the barrel??? How did you make these dust collectors?

Ooooops, you are correct, I forgot to give the “reference” post…

I posted it 517 days ago but the pictures are still in good condition :-)

The “Pre-filter” is collecting – I think – more than 99% of the dust and only very small particles are passing through and stopped by the “Main filter” that remains very clean for very long time…
