The Milwaukee M18 SWITCH TANK 15 L Backpack Sprayer features a 15 L interchangeable tank design, delivering the industry’s first backpack sprayer with no manual pumping required. Its innovative system separates the pump, hose, and wand from the powered base, reducing wear on components and eliminating cross-chemical contamination. The sprayer operates at 120 PSI (8.27 Bar) and includes an adjustable pressure dial to suit user needs. On a single 4.0 Ah battery charge, it can provide up to 2 hours of run time—equivalent to spraying 12 or more tanks—while offering full compatibility with all MILWAUKEE® M18™ batteries for maximum flexibility and efficiency.
