Saw this beast there yesterday (6-28-22), at the store on 75 and 15th street.
Looks to be from the early-mid 80's based on the colors (teal) and the 'tron'-type text used on the model name.
Below are some pictures.
It does run - motor sounds healthy, did not stink (despite a full paper bag inside).
Cord rewinder did work and seemed to have original cord.
Has lots of scuffs but a good cleaning and some plastic polish should help it quite a bit.
Looks to be self-propelled, and it weighs about as much as a Kirby G-series.
Price was 19.99. They ~might~ have a good sale on 7-4 but call to verify.
Also there is an Oreck BB1100DB black canister set that seemed to be missing only the wands. Price was a bit high I thought at 17.99, but it looked clean. Date code was 2008 I think.
Hope someone local gets the Concept One - it is worth saving. Love the color scheme and the logos. However I absolutely do not have space for it so I had to leave it.
