Have you noticed that even though you get a lot of waste in the bottom of your vortex, you still find that the subsequent chambers get very dirty too. These are the very fine particles that do not have time to settle in the vortex and so they get drawn through the transfer port into the next chamber. ๐ช๐ข๐ฅ๐๐๐ก๐ ๐ฃ๐ฅ๐ข๐๐๐ฆ๐ฆ: Black Knight brushes work in three ways. First, they physically trap the large particles that cannot pass through the close weave of the interlocking filaments. Secondly, the filaments have a static charge that โgrabsโ any small particles that are flowing by. This charge holds onto the waste until you do your routine cleaning.
