And with all that woodworking dust, I'm assuming there's a filter on the inlet to the venturi? That will need cleaning probably often.

Why do you think that? In use there is essentially no flow.

It's going to evacuate the air below the piece being held. Then there will be essentially no flow into the venturi. If a guy keeps the thing well cleaned of dust every time he uses it, it probably wouldn't clog. I'm a little skeptical about it.


Have a look at 4:30 in the video where he fills it full of sawdust

You're right. I didn't watch the entire video. I'm impressed.

Both the $60 Lee Valley job (shown) and the $565 by Festool (of
course) are quieter than the cheapie Japa-/Taiwa-/Chi-nese jobs I saw
decades ago. But it's still close to 5cfm just to run 'em. And they
have to be run to hold vacuum. 12psi? Strange figure.
