well okie i smoke abt twice a week, i try and vacuum it every time. i like to maintain my leather hoses cause they rust so easily. but man after u go thick leather hoses u dun go back man, the pull is just awesome. friend got me a obscure brand from saudi arabia, better than any KM hose IMO. 10 smokes, sounds like its ready for a vacuum man. the thing is tht there will be particles in the hose.
