Bokeh Thursday: Shop Vac

How would we ever get by without the serious sucking power of our friendly, hard-working Shop-Vac?! These vacuum cleaners are like house vacuum cleaners on steroids!!

From Wiki:
Drum or shop vac models are essentially heavy-duty industrial versions of cylinder vacuum cleaners, where the canister consists of a large vertically positioned drum which can be stationary or on wheels. Smaller versions, for use in garages or small workshops, are usually electrically powered. Larger models, which can store over 200 litres (53 US gallons), are often hooked up to compressed air, utilizing the Venturi effect to produce a partial vacuum. Built-in dust collection systems are also used in many workshops.
