It's a Kenmore Duo Power upright. I can't tell from the pic if it's the self-propelled model or not. Anyways,, grab it. They're getting very scarce. They were made by Singer/Ryobi if I'm not mistaken, I've forgotten for the moment,someone will correct me. , Matsushita then bought them out. Bags are hard to find now.. I had the green version which somehow disappeared in our move. Their weak spot is the carry handle on the backside of the machine case.. the plastic gets brittle and can crack. I always thought they had the smoothest self propelling mechanism..if it is the SP model there's a 3 speed switch on the back slow/med/fast. They were pretty feature laden for their time with an available hose and tool kit, belt indicator window, 3 speed fan, 3 speed self propelling, adjustable brushroll,, edge cleaning switch, cord reel. The cord was very short though ,, that was an annoyance because you couldn't vacuum a medium sized room without having to unplug it and move all the time.
