iVAC Automatic Vacuum Switch

This convenient, efficient device runs a shop vacuum only when it's needed – in unison with a power tool. Simply plug it into a regular 115-volt outlet and plug the tool and vacuum into their individual receptacles. When the circuitry senses the tool drawing power, it automatically turns the vacuum on. The vacuum continues to operate for six seconds after the tool shuts off to ensure the hose is cleared. The vacuum can also run independently at the flick of a switch.
