A few months back I ask if anyone had tried installing one of the small cheap plastic cyclones inline with a central vacuum. I finally got around to doing so on my very old central system and have to say it worked surprisingly well. I thought that perhaps the velocity through the system would be too great for the light weight dust. Not so. It seemed to get most everything based on the condition of the vacs cloth filter I cleaned beforehand vs what was in the bucket. Look forward to less cleaning of the cloth filter. Going to get a screw on bucket lid for easier bucket removal.IMG_0504.jpg
