There slow , cumbersome and round!!! So corners need to be done anyway!!im fast an very accurate with my suttner turbo noz..21 ltr a min is fast but tiring, I use my 15 ltr for tarmac ,bonded resign etc ...both units run same leads an lances but different t.nozel sizes...I’ve been going 7years an always up the wall..I did use fsc to start but why mess about undoing Leeds etc etc ,,more room in van ,I do have one “just in case” in my garage
Unused for 4 years!!! I do loads of commercial and domestic and I’ve never ever been asked why I dont use one
Also a turbo noz cleans first sweep deffo second...fsc don’t
Then there’s cost..bearings a pain ,jet arms rust,skirt needs replacing
Rant over
