Hello Chris:
 
For all its faults, the short-lived dyson DC11 canister was praised by Consumer Reports for the best tool and suction airflow of all the canisters tested.  Dyson has that nailed down pat.

The cord length is 21ft.  Cord length should be approx. 30ft. or more.  When you have a long cord, there is less amount of time required to stop and move the plug.

255 airwatts I would of thought it woulld be 300 air watts like the UK DC08 TW is!  
 
Doesn't look like it uses Level 3 Root Cyclone Technology!

Hello Tiger21:
 
16.4' according to Future Shop specs with a hose length of 11.89' for a total cleaning range of 38 feet (comparable for most US canisters).  Some of the cord however MAY be needed for the internal cord reel rewind too and unavailable for use.
 
Sometimes these specs are incorrect.

Airwatts depend on the orifice size used,the standard is 2.85, however with diameter size changes,such as half in'' one inch'' one and a half '',etc,the air watt ratings,can change for the high side dramaticly,To put it into simpler terms,put a crevice tool at the machine end and see where these numbers go.
 
The dual cyclone set up works on the same principle

It's just a big numbers game.[right Carmine]
 
150 cfm is not much airmovement. But will suffice in a vacuum cleaner..........
