When running 10 GPM on my 20" surface cleaner, it seems as though it spins so fast it's leaving swirls (not stripes). So I have to slow down. But slowing down defeats the purpose of being able to move faster with the extra volume. Using 15 deg nozzles and a 2 nozzle-1 bar arm inside.
Would switching to a 3 bar/3 nozzle arm or a 1 bar/4 nozzle arm help?
