You must have been asleep in your high school Physics classes. Suction and airflow ARE NOT the same thing! If they are the same, then why is each one measured differently?



Suction is measured in inches of water lift, whereas Airflow is measured in CFM (Cubic feet per minute. You would never hear of a cylinder vacuum suction measured in CFM. Its always measured in inches of water lift.



 



Sure there is a small amount of suction present in a Kirby floor head as the motor starts up, but when it's up to full speed it's all Airflow baby!
