This is the \u003cstrong\u003etool only\u003c\/strong\u003e configuration — the M18 battery and charger are sold separately. The system is built from two parts: the M18 Powered Base (motor, battery compartment, and REDLINK electronics) and an interchangeable 4-gallon Sprayer Tank Assembly (pump, hose, and wand).\u003c\/p\u003e\u003ch3\u003eWhat it does well\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eConstant, adjustable pressure up to 140 PSI with a 24 ft vertical spray height — no pumping required.\u003c\/li\u003e\n\u003cli\u003e5-mode flow rate knob adjusts output from 0.1 GPM to 0.52 GPM to cover a wide range of applications.\u003c\/li\u003e\n\u003cli\u003eDual-diaphragm pump for longer pump life, with Viton seals for durability against harsh chemicals.\u003c\/li\u003e\n\u003cli\u003eUp to 20 tanks of spraying per charge with an M18 REDLITHIUM XC4.0 battery on Mode 3.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eIs this the right sprayer for you?\u003c\/h3\u003e\u003cp\u003eThis is a professional-grade sprayer for landscape maintenance crews who already run the M18 platform and want consistent pressure without hand-pumping. Because the pump, hose, and wand live on the interchangeable tank assembly, you can add a separate tank (such as the 4-Gallon Water Supply Assembly, 49-16-19WS) to switch applications without cross-chemical contamination.
