The Blue Mule Ultimate Wash System 6 is a wash & rinse system for applying up to 6 animal bathing products and rinsing through the same hose. This venturi injection system draws concentrated product from any sized container, mixes it with water and projects the accurately diluted solution through the fur-penetrating 5-hole spray nozzle. Use the ball valves to switch between products and simply close the product ball valves and open the rinse valve to spray fresh water. The Ultimate Wash System 6 is designed for animal bathing, but has countless other applications. This heavy-duty and easy-to-use system will outperform and outlast the competition through superior design and materials.
