I have a new KS120 REB and have watched endless videos on YouTube about the saw. I have it hooked up to a brand new CTM26E with a new bag and a 36mm hose. My question is why does my saw have a film of dust all over after short use, its on the floor, on the saw and ironically also all over the dust extractor. Why are all the ones shown on YouTube clean enough to eat your dinner off after use. Are these videos edited to clean and polish them before filming or are Festool mitre saws not as good at dust collection as they advertise themselves to be.
