Suction vs Airflow: No high suction needed to clean well

[mike811]

Unfortunately many manufacturers show the airflow rating only measured straight from the motor. I have seen even Miele and Sebo doing this and claiming huge cfm figures. Sounds good, but it's far from the real cfm.

158 CFM. Really?

Who needs CFM or waterlift when....

Well Mike81, thanks god we have a standardized label system for vacuums in Europe (EU) .

(I am kidding of course)

Mike81: Where did you buy your Baird meter? I am so taken by this I would like to compare my own vacuums (not for videos, just for knowledge).
