Abstract: A vacuum system having a housing defining a collection chamber with a filter assembly mounted therein. The housing has a suction inlet and an exhaust port defined therein and in gas communication through the filter assembly. The vacuum system also includes a suction device having a motor operatively connected to a suction fan configured to generate a gas flow in the housing. The vacuum system also includes a rotor configured to engage the filter assembly in vibration upon rotation of the rotor. The vacuum system also includes a recirculation conduit having a valve configurable in a vacuum configuration preventing the gas flow from flowing through the recirculation conduit and a cleaning configuration allowing at least a portion of the gas flow to flow through the recirculation conduit to engage the rotor in rotation. A method of vacuuming using the vacuum system is also provided.
