Introduce foam to your cleaning tasks for a powerful effect. The foam nozzle is designed to spray pressure washer detergents into a rich lathery foam. The foam enables the detergent to cling to vertical and horizontal surfaces. The spray pattern size and the amount of foam to be applied can also be easily adjusted. Get the most cleaning power from your pressure washer with the foam nozzle. This accessory is compatible with all RE models.
