The AVA 25° Nozzle is perfect for cleaning your boat or a tractor that needs a powerful clean. It is efficient enough to remove algae, seaweed, dust, and dirt, yet gentle enough on the surface of the boat or vehicle. Move the nozzle closer to extra clingy dirt and further away when rinsing for more gentle treatment. The quality of the nozzle has been optimized to make the water spread in an even spray, preventing water atomization.
