Can someone explain to this vacuum cleaner novice why good suction AND airflow are both necessary. I had an Electrolux Epic 6500 that had strong suction but its airflow didn't seem great. It never groomed the carpet as well as my other Electrolux vacuums do. I put a new brush roll on and had no improvement. The ancient PN1 on my Model L did a better job. But the Model L always seems to have better air flow too. I've been wondering if the poor airflow on the Epic 6500 was the culprit or the design of the plastic wand power nozzle. I remember reading somewhere that good airflow is necessary for raising the nap on a carpet. So I guess it's not all up to the brush roll. Also, how can a vacuum motor produce strong suction and poor airflow? Thanks!Bill
