There is a big diference in cutting nozles for hand and machine cutting in that the machine one is much longer directing the gases and removing whirl.
As for cleaning i have never seen any of my clients clean it, most probably due to all that pressure not allowing anything to stick to it and the distance from the material, the distance is much bigger than with plasma, roughly 5mm above from what i saw.
Again, it is advisable to double check this as i have done very litle cutting with it.
Then again, seeing 100mm thick piece of metal cut relativly clean is quite amazing !
