Clean.....or much cleaner

Strange you and i get completely different results, in terms of airflow the Dyson is one of my weaker machines it pulls a 1.5 on a Baird airflow meter. the only machines that i have that pull less are my tristar MG2 and my compact saniataire thingy. I've tested some of my other machine and if i recall my Electrolux Silverado pulled about a 3 with a dirty bag and about 4.5 with a clean one. what was really surprising was my little Riccar canister, which is no longer mine, had the most airflow at about a 6 maybe even 7. My kirby G6 at the end of the hose pulls about a 6.5 and at the motor housing on low speed pulls a 10, I"m going to do some re-testing as i lost my chart.

yes but I am compairing it to normal vacuums not Kirby's.

I am also not testing it at the end of the hose but at the brush bar , I have a huge test rig that we use to measure the air flow and lift of a vacuum on the carpet.

Also remember I'm 220volt , I have noticed that thier is a slight suction differance between the 220 volt motors and the 110volt.( we get 110 volt in for conversions from people moving to SA)

what is also dirfferant is the noise level, the 110v machines are much noiser.

I have a little aeg( what you guys now call electrolux ) that has huge suction its unreal but it almost cracks its top every time you close up suction.

I'll find my charts awell to give you the right figures.
