Air Watts?
Original Message Mar 5, 2008 10:02 am

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?

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.
