My Volt nozzle doesn't have the gas pump grip on it-just a short metal wand.There is a blast of air coming out when you start the nozzle without it being connected to the host vacuum.Will have to try putting a bag over the wand end-instant broom vac?In the meantime using the nozzle with my NSS M1.Other times use it with the MD Silentmaster.In the future will get a Simplicity "Freedom" cordless vac.Just like using it at the Vac shop.the place has one reserved for me NIB!
