Seeing how it is really tough to get a direct statement, you are saying you agree with my statement?
"For what it is worth I think it (being air watts) is more important than many in the industry would admit but should still only be a piece of the larger puzzle."
 
But then you are claiming you and your fellow "dyson haters" always thought this and then you additionally are claiming somehow this is different than how I have always felt on the matter.
 
If you want to continue to attack a product on airwatts don't you think it would be helpful to simply state what you stand on airwatts is?
 
I did not bring it up but Airwatts seems like a pretty straight forward discussion of fact of measurement and the opinion of how that measurement should be used no need to talk in riddles or play your game of "Gotcha",  "april fools" or claiming I used to feel a different way than I did.  I took some time off this site as many such discussions disentigrate into a game of "gotcha" I simply want to discuss what your experience leads you to believe about Airwatts as you are using them alot lately.

If it would be helpful I can summarize my thoughts.  I think Airwatts is a very important tool (as it measures airflow and pressure) that is underused but is still only part of the puzzle. You state dyson started airwatts and I disagree.  It has is a scientific measurement that was around long before dyson.  I do agree with you that they did come out hard saying it was a much more effecient tool than the Amps and watts you agree the US vacuum industry was previously using.  Seems kind of silly that almost all of the machines in the big box's previously were comparing vacuum performance on how much electricity the machine used.  
First as old timer was alluding to for Airwatts to be useful it needs to be measured at the point of cleaning.  Many central vac guru's are now using airwatts and I think they should only be compared at the point of cleaning not at the motor.
Second Airwatts needs to be measured over time to compare effect of a dirt load on the machine.
Third when coming up with airwatts part of the equation is the pressure rating.  Most quality machines have pressure relief devices to save the motor from burning up and these can skew a pressure rating.  I beleive the pressure part of the measurement should be taken as the the machine would normally be used without the pressure relief device activated.
 
Finally I think these constant airwatts should be used much more and are very important but once again only part of the total equation.  Sorry if you assumed I have had different thoughts on the subject as I have not.

Hello JimB:
 
If you reread my post to JD you should quickly see the point I was trying to make.  Here's a simple rephrase and clarification:  Dyson and its supporters for 5 years claimed that air watts is the quintessential being of its superior performance over the competition.  (The critics of dyson's claim, labeled dyson-haters, argued that air watts is ONLY one piece of the vacuum's performance.  Not the total package and the end all and cure all for vacuum ratings).  
 
Then, dyson proceeded to compromise the performance measure (it proclaimed to set it apart from the competition) on all subsequent models.  How?  Two ways, as I indicated in my posts several times: By reducing the air watts by one third (from the 300 on DC07 to 200 on DC18 in less than 5 years) AND removing the air watts' ratings from the USA dyson Web site for the higher air watts rated dyson models (presumably thinking that customers wouldn't notice?).  And by the way dyson just happened to charge more and more too.
 
That marketing strategy may sell well in the UK and other countries.  I think US buyers are more savvy.  
 
What part of these above facts have I misstated, are incorrect and/or you want to disagree with?

Carmine, the Premier Junior, circa 1927-29, I'm getting does have a revolving brush and side mounted bag.  I have a Premier Duplex of the same era and the larger companion to the Premier Junior, and it has a revolving brush and side mounted bag.
 
I believe Premier uprights of the early to mid twenties were straight suction with a rear mounted bag.  The Frantz Premier, which came out about 1912 and which preceded the Premier, was straight suction with a rear mounted bag.  I have a Frantz Premier from about 1917.
 
If my information about the Frantz Premier is correct, Jim Kirby worked with the Frantz Brothers in the design of the Frantz Premier.

After my previous post, I remembered that General Electric uprights of about 1927-29, which looked very much like Premiers, were straight suction.  GE had a standard and Junior upright.
 
Didn't GE acquire Premier about 1930?

Yes, Jim I think it was around the beginning of the depression era ( "the Great Depression" ) in the USA.  As I mentioned in my PM, you ask questions that very few people left on earth can answer.  Even for those of us who do not yet have full blown alzheimer's, it's a real challenge.

To calculate the electrical power used in an appliance, use the following formula:
 
Power in Watts (P) = Current in Amperes (I) x Voltage (V), thus P=IxV.
 
To find the current, divide Power by Voltage: I = P/V.

I have to disagree with you here.  I believe the messaging was that by measuring airwatts as dirt load increases was the only to tell if suction was remaining constant after 4, 8, 10 etc... ounces of dirt.  The messaging never was dyson has X airwatts and Y competitor has Z airwatts.  The messaging was that dyson's airwatts stay constant and other brands have a reduction in airwatts after 4, 8, 10, etc... ounces of dirt.
I believe one of the secrets to dyson early success was that general messaging without naming competitors while Hoover was giving dyson immense help in gaining credibility and name recognition by slapping the dyson name on the front of all their top end units boxes.  Much like here at this site it would not take a rocket scientist to visit here and form a quick opinion on who is the current top dog all the competition is gunning for.  IMHO the constant critique of dyson on this site by those in the industry that do not carry the product  but seem utterly frustrated by it's success only helps build the "buzz" and legitimacy as the current brand to beat.

Hello JimB:
 
(Hopefully this is the last time I have to put this in print on the Forum.  It's getting redundant.)  
 
In response to your disagreement:  As dyson critics of what you say above (labled "haters") pointed out 5 years ago when dyson and supporters made this claim, this is only one piece of the performance equation for vacuums.  Not THE end all and cure all.  Apparently over the last 5 years dyson and its supporters have come around to agreement with the dyson critics since the dyson air watts have been reduced on every subsequent dyson model made.  And dyson eliminated the air watts' ratings from the tech specs on its US Web site.

This is "buzz" and factually unsubstantiated opinion promulgated on the Forum and it originates from dyson, dyson supporters and dyson fans.  I have not seen and/or heard any authoritative industry numbers since 2004 to show that dyson still leads vacuum sales in the USA by dollars and/or units.  I have not seen/heard any authoritative industry numbers to show dyson is a better vacuum brand seller than Dirt Devil, BISSELL, HOOVER, SEARS Kenmore, and Eureka.  Just to mention a few of the better known brands that compete with dyson at the big box stores in the USA.  
 
Just the opposite is true.  I've heard that dyson sales in the USA and in the UK have decreased from year to year.  Why and how?  NPD counts new vacuum sales when the maker sells to the retailers.  Dyson sales for DC07, DC14 and DC15 models were counted as sales in 2004 (the last year dyson issued its press releases worldwide about the success of its US dyson sales).  Many of these dysons (already counted as sales) are still in stores' inventory on the shelves and being sold today by big box retailers.  Almost 3 years after the fact and the last time authoritative dyson sales numbers were substantiated by the NPD.  
 
If I missed some industry facts to the contrary on dyson sales since 2004 please share them (facts) with Forum readers.  We'd all like to know what the real dyson sales numbers were after 2004 and are today.

You are right no need to be redundant Wink  You say dysons original messaging that the total airwatts was the "end all cure all" and I say you missed the message and the message from the beginning was consistency of not losing airwatts with increasing dirt load thus thier "no loss of suction" mantra.  I can't remember reading on piece of dyson marketing that said the total airwatts was the "end all cure all" it is a little revisionist history to make your argument.
 
You are absoutely correct that my comments about the "Buzz" were my opinion thus sentences beginning with "I believe" and "Imho".  I have no allusions that just because they are my educated opinions that they immediately become fact.  It is a distinction that some struggle with.
