Manufacturing date
Actually, 111 means it was made during the first quarter of 2011. Pretty much the same time frame though. So you have literally one of the first ones of the e2 black. Yours will have the center, flat belt power nozzle, and the canister won't have the red diagnostic light on the front. Other than that, it's the same as the current model. That's an amazing deal. I have the new model with the side belt, but I need a hose. The original purchaser damaged the hose, or lost it in a move or something, I'm not sure. I'm hoping to find a nice clean used one. Right now I'm having to use the hoses from my one speed e series.
