ABSTRACT:
A vacuum system has a cabinet that can be mounted to a wall. The cabinet includes a hose storage compartment with a hose drive assembly for automatically extending and retracting a vacuum hose. A portable vacuum unit can be removably docked to the cabinet and connected to the vacuum hose so that waste can be picked up the vacuum hose when the portable vacuum unit is docked. When undocked, the portable vacuum unit can be used alone.
