The WVC50 was GMC’s wet and dry vacuum. GMC went into receivership in 2008 and the brand disappeared from the market.
Suction is not the specification that matters
Every shop vacuum has enough suction to pick up chips. What separates them is what happens to the dust afterwards.
A basic vacuum with a cloth or paper filter captures the coarse fraction and blows the fine dust straight through the filter and back into the room. The particles small enough to pass are exactly the ones that stay airborne for hours and go deepest into your lungs.
So the specification to look for is the filter: a genuine HEPA cartridge at minimum, and ideally certification on the whole unit rather than just the element — which means the seals and the airflow path are part of the rating, not only the filter media.
The feature that decides whether it gets used
A tool-triggered outlet. The vacuum starts when the connected tool starts and runs on for a few seconds to clear the hose.
It sounds like a convenience. In practice it is the difference between extraction that runs for every cut and extraction that gets skipped for short jobs, which is most jobs.
What to buy
The Festool CT 15 E HEPA, linked below, has both: whole-unit HEPA and a tool-triggered outlet. It is expensive, and it is very good at the specific job of capturing fine dust at a sander or a router.
The cheaper honest route is a decent shop vac fitted with a HEPA cartridge, plus an inline auto-start switch. It is louder and the filtration is not certified, but it collects the dust and costs a quarter as much. For a garage workshop that is a reasonable trade.
