Gentlemen, A couple clarifications:
Didn't i read he sold more to the cleantalk boys than in the whole USA .
Why no heat ?
Mainly because at USA 120v he has maxed each cord amp draw wise
...
1. We have manufactured equipment since 1977-78. We do a pretty good job selling equipment here in the USA and abroad, so I'll leave this to anyones imagination if we sell more in the UK, or right here where we began. I can also pass along the fact that they have moved a lot more equipment in the European market than 30; not that it really matters.
2. Here in the USA, 120v heaters make no sense at all. Can't really heat fast enough to satisfy the Operator. Therefore, we provided additional performance in vacuum/CFM's.
Great questions and answers above, Gentlemen. You have a wonderful board. 
Best always;

Saying as its me thats quoted , i would like to say , hopefully without sounding disingenuous , that any remarks or criticism i made are not suppose to sound too serious or personal .
I usually get sucked into discussions when certain claims are made by a few over zealous jag owners here or those posts trying to understand some of the performance claims for the 6.6 motor .
Where as the CA machine undeniably works very well in many areas , my own personal reasons while at this time i wouldn't buy one would be as follows ...
I did own a used scorpion for some time and while the motor performance was excellent , i found a few issues i didnt like ...
The waste tank design i feel places an unnecessary extra cleaning burden on the user as it doesn't fully empty and if for example the machine is van mounted it is an extra hassle to open the side bung , place a container , tilt the machine etc ...
also odor within the tank on a busy day is not desirable if you have bring it indoors unexpectedly for any reason .
I also found the cutoff floats rarely worked before water would enter vacs .
I didn't find it easily maneuverable and stair climbing is something most would only try once , i would prefer a forward facing handle also to pull the machine along side when walking or pull it through loose stone ground .
As you seem to admit above Europe 230v is not considered in design ... we could have either heat or even more vac performance to make optimum use of whats available here .
Also it would have been good to have tested the 6.6 and made the data available ...
No doubt it performs very well but there was much confusion and many in accurate claims made . still we dont know , we have mytees video claiming 250 cfm for two 6.6 .... jan sullins has tested at 270 cfm .... and now the Uk distributor claims 325 cfm ! great if true but seems optimistic , strangly its the same figure they got when testing the scorpion ... perhaps their gauge is stuck
Just some of my views , i know its easy to be critical , and if the jag was in a newer revised body sometime i would consider buying for sure .
