If my vacuum can remove even one spec of dirt that yours misses, then mine is better than yours - even if there's no proof that mine would have picked up as much dirt as yours...

Venson, Regarding the Dyson DC28, CR said the following: CR's Take
Overall, this is a very good, if pricey, upright that was among the better performers at cleaning carpets and bare floors, and for picking up pet hair. It had very good airflow for tools, and was excellent at keeping its emissions low, but it scored only fair for handling. Dyson has been among the more reliable brands of upright vacuums.
Highs
The Dyson excelled at cleaning bare floors and keeping its emissions low. It was also very good at cleaning carpets and picking up pet hair, and had very good airflow for tools.
Lows
This model is pricey and was fairly hard to push and pull. ****** Regarding the Rainbow's fair score for carpet cleaning, you may be right that the power nozzle is the weak link. I still think it's odd that the Rainbow has the absolutely lowest score on carpet cleaning among all vacuums tested. However, I'm not sure how CR determines how much dirt is removed from a rug. CR considers that information to be proprietary.
The smart tyrant writes his own story to ensure that it is favorable. The lazy will repeat lines from the book without fact checking.

Consumer Reports is what it is. For the most part, they provide accurate comparisons of vacuums performing the exact same tasks. The question is always how generalizable the test results are to other carpet/flooring and dirt types.
Odd vacuums like the Rainbow with the dirt collected in water provide unique challenges to the lab. I have always wondered how the Rainbow could do so poorly in the lab tests, when they seem to do well in real world tests. I always wonder if they forgot to hold down the lever to keep the power nozzle operating, or if they don't properly calculate the dirt removed from the rug due to the water collection. It just doesn't seem right for the Rainbow to get a "fair" score for carpet cleaning and a "good' score on bare floors cleaning (most recent tests - in the magazine that came yesterday). Heck, the miele art got a "good" on carpet cleaning (way back when it was tested), and it is straight suction.
FWIW, the Dyson DC28 made the top ten at #10 right above the Kirby Sentria. Hoover has quite a few of the top spots.
Hello Severus:
When CR rated the MIELE Art series 'good' at carpet cleaning W/O a brush roll, I was floored. And it further reinforced my view that I expressed above about the CR ratings/rankings: A guide and not the final word. Carmine D.

Hi Severus, I believe that the weight of the dirt picked up during the test would be compared against the initial amount of dirt put down for the test. The collection device of the vacuum tested -- dust bin or bag -- would have to be weighed before use and then after. However, I've no idea of the prescribed time window for the test. Venson

So we are to use CR as a guide ======unless it supports your argument.
You have been criticizing Dyson and supporting Oreck. You hinted that the upcoming CR ratings would support your claims. Now that it doesn't you brush CR ratings aside. More BS.

HS:
I thought we left off at Best Buy extended service plans and product replacements. Did you do some homework and decide to pick up your sign. There are alot left. WRT CR [Consumer Reports], it's a starting place. Gives shoppers a background and comparison of SOME of the available vacuum products, features and prices. Retailers use CR as a way to determine what to carry/sell. Retailers use CR to promote sales of particular brands. I made no mention of the October 2009 CR ratings and rankings. Thank you very much. The last prediction I made was in Dec 2008 in response to a poster here [Tomas] asking for comparison opinions on the SEARS Progressive upright [$250] and HOOVER WT Anniversary SP [$150] edition at COSTCO. I said after recommending the HOOVER based on price and performance, that this partilcular HOOVER model may dethrone SEARS in the number one spot in CR in March 2009. One of the many times, I was right.  I grow weary of correcting you all the time. Carmine D.

I was under the understanding that it was actually the carpet sample that was weighed, both before and after cleaning.

Hello Dusty:
Excuse me for chiming in. I hope it's not the rug sample, tho I always say a rug can hold its own weight in dirt and look clean to the human eye. I believe WRT Consumer Reports it's the mass/weight of the test materials before and after the vacuum is used. Carmine D.

Good morning Carmine, As it was explained to me (and it's quite possibly incorrect) CR clean and weigh a sample carpet, add 100 grams of whatever CR uses as dirt, use a machine to force the dirt deep into the carpet and then vacuum the carpet a set number of times. When the procedure is done the carpet is reweighed to see how much of the 100 grams is gone. Dusty

Hello Dusty:
I've never heard it being done that way. But maybe its changed. Carmine D.
