Works great, but it sounds like a dieing elephant because of the ridges in the tubes. I’ve not tried my dust deputy with drywall dust, probably too fine for that. Dust deputy works great for the cnc though! I’ve filled the 5 gallon bucket with sawdust a dozen times now and haven’t had to replace the filter in the shop vac once since then. I use it to clean up after my table saw and chop saw, so that’s quite a bit of crap to clean up.
