Industrial vacuum cleaners work basically the same as the ones people use in their homes, but they are tougher and more durable, because they have to withstand more extreme usage. An industrial vacuum uses two motors, unlike residential vacuums that use one motor. Industrial vacuum cleaners also use circuit boards to dispense power to the motors, which is more advanced than home systems. Several of the latest industrial vacuum models will even turn off the beater brush motor or divert power when the suction wand is used, making the most of their power. 

There are also wet vacuums, that are the same as those other industrial vacuum cleaners, but they have more protection in place for the motors and other electric parts. The way that the motors work in wet vacuums is with a waste canister that draws air in with the hose to the motor, where an exhaust vent is waiting. A simple floating ball keeps the liquid in the wet vacuums from getting out of the canisters and into the motors. All electrical components on wet vacuums are also sealed, to protect them from damage. 

There are also industrial vacuum cleaners that use cyclone power in their motors, which produces a vortex effect. A cyclone industrial vacuum uses a beater bar that pushes debris into the suction tube, where it is then sucked into a sealed container. Then the debris is moved toward the outer walls using centrifugal forces. Then the debris in the industrial vacuum slows down and is dropped into the bottom of the container. Most cyclonic industrial vacuums don't have to use filter bags, but sometimes this can compromise air quality because of escaping dust particles.

 

HafcoVac sells vacuums that include many features, including wet or dry industrial vacuum cleaners that use compressed air.
