Makita Router vac hose extension accessory

My Makita Router (RT070) came with an accessory piece that’s designed to extract dust.

Do I still need to incoporate the Router Plate with vacuum hole ??

Does the vac support rotate around the base freely? If not when the router is mounted on the plate the vac tube may interfere with the cnc.

If this isn’t a problem you’ll likely pick up a fair amount of the dust through that setup. I would think about trying to use both options perhaps with a creatively designed y adaptor.
