The motor is stationary, and only the ball moves? That's not how it looks in the pictures. It looks like the ball and the motor move together. I guess I'll have to see one in person.

yes I see...much simpler design with motor stationary.

I was expecting to see less air watts for the US model and I'm sure Dyson would come out with more.
 
Our models "All Floors" are called Allergy in the UK. I think the name Allergy is a lot better then calling a vac All Floors

Since today is Thursday (LAUNCH DAY), I can finally tell you all how the thing works.  I have been dying to tell people for a long time now.
 
OK, the ball of course does the rolling, the motor is stationary within the ball.  Since there's no belt drive, the armature ends at the bearing bridge.  That way, the motor (same as a ConstantMAX but without belt drive shaft) takes up less room within the ball.
 
The suction TO the motor as well as the exhaust FROM the motor are on the same side of the machine.  It's larger on the left hand side than on the right hand side if you stand behind the cleaner (as if you are using it). The curved tube leading from the pre-motor filter chamber on top of the high efficiency cyclones, curves down, snaking it's way down the side of the main frame. But, at the point it's level with the Hepa exhaust filter, it breaks into TWO tubes, molded together (sort of).
 
The smaller, top tube carries the air away from the motor, so it's a SIDE entrance to the hepa filter chamber (instead of underneath as in all other Dysons).  
 
In effect, the whole 'side' of the ball is open on the one side - with the side tubes being part of the motor 'mounting'.  The air enters the motor fan directly (there's a seal between the fan case and the intake tube - about the size of the rim of a waterglass.) The air goes through the fan, over the windings, and UP and over the top of the motor to the outlet tube which is situated directly above the intake tube on the same side of the cleaner.
 
It's not that difficult to get the motor out.  The ball comes apart with four screws, it's very easy to work on the machine, much more simple and less complex, even though it might not seem so to the average person.
 
What Dyson has done, is to take things that have occured in vacuums before, and put them together.
 
The ball was done once before - with the motor within a ball center wheel.  The swivel joint connection that Dyson's so proud of has been done before, exactly, on the Air-Way Sanitary System dual motor models in the 1930's.  It's a virtual copy of the Air-Way Swivel Joint (which was a patented Air-Way feature).
 
It's interesting, to me anyway, that Dyson has been able to make this machine both very user friendly and very intimidating, all at the same time.  Women will NOT like it.  It's not a woman's vacuum at all, this DC15.   Only a man would buy it.    
 
Carmine, grab onto that cold, dark heart of yours, because what I'm about to say should push you right over the edge.  I THINK IT'S TOO EXPENSIVE.  It's $600.  The Animal model is $700.  I can't ask someone to pay $700 for a vacuum cleaner, I just can't.  I would never pay that much for any vacuum.  How can I ask my customers (many of whom are also my friends and neighbors) to spend that much money on a vacuum cleaner?  Perhaps best buy and Sears are biting off more than they can chew.  Now that Wal-Mart is getting the DC07 yellow as well as the Low Reach...  And Wally World has to sell them for the same price as everyone else. Haaah!
