Duo Power...
Corey,
I suspect the nozzle of the duo power was designed like that for better pickup, an attempt to spread the suction across the whole nozzle, whereas the DAM had all its suction over on the side, and for the early models(1100/1110/1118/1120, early 1130 and 1140) with the old helix agitator which actually spirialed the dirt away from the suction and towards the belt end...
If you have an early DAM with its original agitator scatter some unpopped popcorn kernals on the floor and try to sweep them up... see what happens!
This Duo Power is much more deluxe than the DAM too, two speeds, cord reel, headlight. Its kinda a hefty beast though too.
I like the sound too, once this one runs for a bit and the bearings quiet down it sounds just like a canister.
The tool suction is similar to a DAM too.
Austin to my knowledge On board tools were never thought of with this machine.
Kyle: sorry, not for sale or trade at this time. There are still Dou Powers out there, I am sure you will find one.
