  • Improved air flow
  • Less time changing your shop vacuum bucket
  • Enhanced fine dust collection

First, shop vacuums are loud. Really loud.

Which makes having a shop vacuum on the whole day not only hard on your ears but hard on the motor that (for most) weren’t built for continuous duty.

So, when making a dust collector from your shop vacuum an absolute must-have is a power switch that will turn the vacuum on and off when your power tools need it.

How these work:

  1. Plug your vacuum into the “power tool” outlet.
  2. Attach your tools connected to the dust collector shop vac
  3. Power on your shop vacuum (notice it didn’t start)
  4. Turn on your power tool and hear the shop vacuum turn on.

Pretty nifty, huh?

Deciding on a Dust collector or SHop Vac

Best Dust Collector for Woodworking Shops

First, a woodworking shop that is busy most weekends (and weeknights) absolutely needs a dedicated dust collection system.

But if you’re new to the hobby and just starting there are plenty of reasons to consider a hop vacuum dust collector over a more pricy system.


  • A shop vacuum is likely something you already own, so adding a vortex system is a purchase you can justify for $50-100.
  • Full scale dust collectors are loud, take more power and use precious floor space.
  • And, of course, a dust collector investment takes away cash from other purchases like mobile bases, miter saws and other tools.

Dust Collector vs. Dust Extractor

While a dust collector is great for high volume jobs, a dust extractor is best for grabbing dust from hand tools.

In general, a dust collector will:

  • Have a 4″ hose
  • Support separation of large wood chips from planers or jointers

Meanwhile a dust extractor will:

  • Fit small hand tools
  • Is designed for small particle dust (not chips)
  • Pair with your tool to turn on and off with the tool

While a budget consideration for most, it is actually best to own one of each. And especially if your projects include a steady diet of orbital sanding, which is a serious dust maker.
