Let's talk shop vacs

I have a simple one, not name brand but same wet/dry vac concept.

What do I need to do to make it blow everything out of the exhaust rather than collecting in the body/tank/whatever you want to call it? I figured hooking up a hose to the exhaust port would so it but not enough force to blow everything out.

Ideally I want to run an exhaust outside so all my wood dust can just get blown outside my shop instead of collected. Plus I’m dealing with blown in insulation in a bathroom remodel and would rather pump it into the adjacent knee wall attic instead of removing 10 trash bags worth.

Every time I search online I just get problems about the exhaust blowing debris out and needing to change the filter blah blah blah.

Oppo I need your help.
