Abstract: A vacuum unit includes a debris tank receiving wet or dry waste. A multi-cyclone separator is coupled to an outlet of the debris tank. The multi-cyclone separator receives the wet or dry waste from the debris tank and the multi-cyclone separator includes a plurality of cyclones. A filter is coupled to the outlet of the multi-cyclone separator and receives exhaust airflow from the multi-cyclone which then flows onto the blower or fan and is vented external to the vacuum unit.
