Kirby 519 VS Kirby D80 

This is a request video for ClassicTVMan1981X (Benjamin Edge). In this video, I demonstrate the airflow of my vintage machines. The Kirby Dual Sanitronic 80 has more airflow through the nozzle, but the 519 will pull the roll away if it is adjusted closer to the floor. These tests I do don't mean that one machine is better than the other; it just shows which machine has the most airflow through the nozzle. When adjusted at the correct height, any vacuum will clean your floors, carpets, etc. at its peak efficiency.
