Shopvac drywall attachment too restrictive?
I find the models that use filters plug up quickly. A contractor friend showed me what he had made using a 5 gallon bucket and plumbing fixtures. one pipe goes in and a 90 at the bottom of the bucket capped off then drill a bunch of 1/4" holes in the short pipe at the bottom. fill the bucket 1/2 way with water the suction pipe is short only 1" from the top the dust comes in and when bubbling up through the water the dust is trapped in the water, when you notice dust rinse and put fresh water in the bucket works great and no filters to buy. I have had mine for a few years. If cleaned at the end of the day it is not hard to clean if you forget it is a lot more work to clean out.
