Pound for pound, the CFM output of vacuums doesn’t come close to the CFM of leaf blowers. Probably because of the lack of filtration. And I guess that’s the point. Why filter material the wind would just kick up in the air naturally anyway? This is a waste of energy and time. Obviously if you are blowing material that normally wouldn’t be outdoors for the wind to blow around naturally, that’s a different story.

I will admit, the sound is really annoying though.
