These questions do not pertain to overhead/guard collection.
The portion of the DC setup that disappears into the cabinet... Is that just laying on the ground inside the cabinet and picking up whatever lands there? Or, is it attached to a funnel type of attachment underneath the blade to collect the dust before it can fall? Does that funnel have any effect on pulling dust through the insert plate?
If a funnel setup, do you have a picture or can you explain how that connection is made?
Thanks!
