The patented, bilateral nozzle design assures that the debris will break free and be launched out of the gutter onto the ground not on the roof. Two opposing nozzles evenly matched assures the recoil from one nozzle is offset by the other. The nozzles are focused linear, i.e. directly in the trough of the gutter, not coming in from the top.
It comes standard with a 4 gallon per minute nozzle. 5 and 6 gallon per minute nozzles available upon request.
