Vacuum Cleaners Discussions

HS:

Dyson uses air watts as a measure of performance for his products not me.  I made a logical conclusion about dyson canister models based on dyson's standard of measure for performance.  A 30 percent reduction, if we are to believe dyson's standard as relevant to performance, is significant.  Or, should we believe that dyson's own measure of air watts is irrelevant and insignificant to dyson performance?

Your [and your dyson cohorts here] defense and support for failed dyson products and the shortcomings of existing dyson models undermines your vacuum judgement and credibility not the nebulous vacuum industry dealers you speak of in the generic sense above.

As I opined,  dyson needs the M-O-N-E-Y!  Cash.  Capital.

Would you like me to repeat myself.   Here it is once again:  200 airwatts for a DC22 is a far cry from full size power when and if compared to a DC11 's 5 year old 275 airwatts and the latest DC19 T2 with 280 air watts.  The dyson site calls a DC 22 full size power.  I didn't.   A reduction in performance by 30 percent is not ONLY a loss of 30 percent, as you would have us believe.  It's a loss of a huge 30 percent of performance.  As I opined before, the smallish 7 inch cleaning swath on the DC22 rug nozzle is not for the sake of manueverability [as some dyson fans here would like us to believe] as much as its due to lesser performance power.  The rose color dyson glasses are obstructing your reading and comprehension.   Not to worry.  I can repeat myself for you until it sinks in.

Air flow and air watts can be skewed.  There are many variations in the resistance to air flow that should be considered when measuring air flow. Air flow may not be a measure of system performance. In addition to the resistance within the power unit, there is resistance caused by air turbulence in the hose and tubing, restriction where the cleaning nozzle contacts the floor, as well as increased resistance within the filtering system as the unit fills with dirt. High output (air watts) is not the only factor to consider in determining performance.

I would think that sustained air watts is a better indicator of performance than is peak air watts.

Carmine, Mole, Venson, Dusty and many others are much more qualified to answer this than I.  Carmine is just being timid or cantankerous.  I suspect the latter. 

HS:

I have always maintained that air watts plus proper brush agitation are critical for rug cleaning performance.  Always.  The dyson supporters here, going back to the beginning of dyson's DC07 launch time when I first criticized the sub-par petite non-industry standard brush bar in the DC07, claimed the higher air watts more than compensated for the whimpy brush.  An opinion that I disgreed with.  Put the 2 shortcomings together: Lower air watts and a poor brush roll design and you have a formula for poor performance for cleaning and grooming rugs.

Carmine D. 

Agreed, a 30% loss is substantial.  However, others and I believe you have contended in the past that Dysons high air watts were useless as factor in determining performance.  I believe that this may have been said because Dyson higher air watts than some favorite brands.  Perhaps the 30% loss will affect performance if the vacuum is designed properly in other ways (which I doubt that it is). 

These rose colors are better than the drab ones you see. 

Poor suction and a fantastic brush will only cause the dirt to be pushed out of the vacuum path.  Looks like a double edged sword.

Now quit posting until I am finished.  Go to the casino or ride the roller coaster.  Have a good week end too.
