Air Watts?

I've come across this spec in Dyson reports and also for Central Vacs. However most other upright vac vendors call out motor power instead. Can anyone explain to me why there are two power ratings out there for vacuums? I understand what air watts are but I don't understand why there are two different specs. To use a car anaolgy is this like Horsepower vs Brake Horsepower?

This airwatt stuff reminds me of,when we thought we had all the answers,they changed all the questions,All you really have to do is put your hand at the end of the suction hose and feel it. The usual customer reaction is WOW,mine dont do that. MOLE
Did that back in the 50's with the canns and tanks. If the hose end stayed on your palm with the vacuum running, it was worthy of buying and selling!

Air Watts (IMO) are basically marketing mumbo jumbo. Most of these ratings are taken at the motor, sitting on a bench and not attached to any vacuum. The minute you put a motor in a can and add a bag or filter all of the specs will change...

Ah but, are they not usually specified in the adverts (at least here in the UK, anyway) as,
eg; "410 AirWatts (measured at hose end, when empty: IEC60312, or whatever)". I would presume that the cleaner is tested as you would find it in its box, with hose, without floor nozzles.

Here (Canada) most central vacuum systems give the Air Watts in their brochures or even on the front of the unit. In both cases, it's motor only, not installed in a canister and no hose attached.
