I must have bought the same cleaning set as [member=8955]Coen[/member] because my 36” braided hose doesn’t do this either. But the hose that came with my ct15, the black antistatic hose, has the newer style fitting on the large end that allows it to connect end to end with other tool ends, and it seems to trap bigger pieces of debris at the entrance to that fitting just inside the hose and then clog up. Not sure if this is caused by this specific hose, or the new style vac end fitting that is now common but just last night I was getting very annoyed as I tried to clean up my mess from the days projects.
