Thanks for posting this Charles. Where is the PN connection on the cleaner,,and is/was the hose electrified, or a PN cord attached to the hose? Also what did/does the hose handle look like,,and is/was there a plug for the PN at the hose end of the wand? Thanks for all the info,,very interesting. Ive never seen one of these vacs in person. Im assuming these were simular/clones to the Kenmore's of the time?
