I have done several videos about this topic and results have been always the same. High airflow vacuum with very low suction picks up much better than the low airflow vacuum with the very high suction.
Some people have don't seem to believe this.
Let's take Dyson for example. Dyson vacuums have very high level of suction, but poor airflow. They claim is "highest suction of any vacuum cleaner from the cleaner head". It might be, but it doesn't make it clean well, because of the poor airflow. I have seen many impressive looking Dyson demonstration videos where it agitates and picks up very well from the low pile carpet. Dyson never talk about airflow, because they know, that their vacuums have a poor airflow.
So I tested my highest suction (poor airflow) vacuum what I have (Vax/Hoover Air) vs Kirby G6 with high airflow (poor suction).
You can clearly see the difference.

Special thanks to Bill for inspiring me to do these tests.

Your welcome! It's nice to inspire people to see something different. As a reminder, my Dyson DC14 has 112" of lift at the hose and 59 CFM at the nozzle. A G6 (just like yours) has 32" of lift at the motor base (low speed) and 120 CFM at the nozzle. The Kirby deep cleans easily and the Dyson simply can't at all.

I agree totally

This is why old straight suction uprights clean ok,and why high airflow canisters such as Apexes Strato Cleaner or the Sunbeam Dual Deluxe outclean many newer machines, I have a NSS Pig that really does not have a lot of suction, but the airflow is so great that it outcleans just about anything else.

Also why

A old Kirby with the hose attached will seem to have no power, but will do dusting chores quite well...lots of airflow!
