I have a VSR90 and only use it for detail work because of the size of the color cup. As far as cleaning goes, I also have a VL, and the two of them I clean the same. Put thinner into color cup, spray through gun, unscrew handle, loosen collet nut that holds needle, remove tip, push needle forward so as to not drag paint back into gun, rinse needle and tip and blow thinner through gun. This is for total cleaning. Naturally if you are going from one color to another I just blow thinner through the gun until it runs clean and then start with my next color. I hope this helps.
