Abstract
A vacuum system has a cabinet that can be mounted to a wall. The cabinet includes a hose connectable to a vacuum source. The hose is extendible from the cabinet between extended and retracted positions. A rotatable shaft drives the hose and a power source causes the rotatable shaft to rotate. A sensor measures the speed of rotation of the shaft and signals a controller to stop the power source when the speed falls below a predetermined threshold.
