The MILWAUKEE® M18™ SWITCH TANK™ 4-Gallon Backpack Sprayer delivers the industry’s first interchangeable tank design with no manual pumping. Designed to meet the needs of professional landscape maintenance, the battery-powered backpack sprayer delivers instant, constant and adjustable pressure up to 120 PSI and a 25 ft spray distance. The 5-mode pressure adjustment knob adjusts the pressure between 20 – 120 PSI for a wide range of applications. The M18™ REDLITHIUM™ XC3.0 Battery (sold seperately) provides up to 12 tanks of spraying per charge. The sprayer has a dual diaphragm pump for longer pump life and Viton® seals for increased durability against harsh chemicals. The sprayer tank has a wide mouth opening for easier pouring and a strainer that filters debris from getting into the tank. The backpack frame has wide straps for added comfort during extended spraying applications and a handle for convenient transport and storage.

The 4-Gallon Sprayer is made up of two components – the M18™ SWITCH TANK™ Powered Base and the SWITCH TANK™ 4-Gallon Sprayer Tank Assembly. The Powered Base includes the motor, battery compartment, and REDLINK™ electronics. The interchangeable Tank Assembly includes the pump, hose, and wand. The isolated pump, hose, and wand design allow different tank assemblies to be added for different spraying applications, eliminating cross-chemical contamination. It also allows the tank assembly to be replaced at a lower cost of ownership compared to replacing the entire sprayer. The Powered Base is compatible with the SWITCH TANK™ 4-Gallon Concrete Sprayer (49-16-28CS) and 4-Gallon Water Supply (49-16-28WS) Tank Assemblies. The M18™ SWITCH TANK™ 4-Gallon Backpack Sprayer is part of the M18™ system which is fully compatible with over 175 tools.
