12" rotarysurface cleaneross removal

[MARTY1973]

Hi, I have a wilks 750 8HP 4000psi 11 lpm pressure washer and I bought a 15" surface cleaner inly to find it does not remove any moss in-between block paving. I researched and it says I should only have a 12" surface cleaner. Would anybody know before I purchase one whether because its smaller in size it will be that more powerful that I will remove moss and dirt build up better . Only do smaller jobs . Any help would be great ??

You need it jetting for your machine but to be honest no 11 lpm is never going to run any flat surface cleaner successfully and remove moss it’s no ware near enough flow , 15 ltr is minimum 21 preferable .
