The Industry’s First Interchangeable Sprayer and Water Supply System

MILWAUKEE, WI – Milwaukee Tool is once again delivering unrivaled productivity to the professional trades with the introduction of the industry’s first interchangeable tank solution, the M18™ SWITCH TANK™ Interchangeable Sprayer and Water Supply System. Core to the new system is the M18™ SWITCH TANK™ Powered Base, which provides power to three different interchangeable tanks: a 4-Gallon Pesticide Sprayer, 4-Gallon Water Supply, and 4-Gallon Concrete Sprayer. The M18™ SWITCH TANK™ Interchangeable Sprayer and Water Supply System delivers instant, constant, and adjustable pressure with no manual pumping, and users can easily add on or replace any of the compatible tanks.

 “As leaders in cordless technology, our goal is to create solutions that completely disrupt the way work gets done to make users more productive. The M18™ SWITCH TANK™ System is a perfect example of this passion at work. Through its unique interchangeable tank system design, users can add on additional tank assemblies to eliminate cross-chemical contamination. This also gives them the ability to simply replace the tank only versus the entire sprayer or water supply, delivering lower cost of ownership across the board. Finally, this entire System is powered by M18™ REDLITHIUM™ Batteries and REDLINK™ Intelligence to provide the performance, run-time, and capability demanded by users without the need to manually pump.” – Andrew Lentz, Group Product Manager for Milwaukee Tool

How It Works

Each SWITCH TANK™ solution is made up of two components – the M18™ SWITCH TANK™ Powered Base and the Water Supply or Sprayer Tank Assembly. The Powered Base includes the motor, REDLITHIUM™ battery compartment, and REDLINK™ electronics, while the interchangeable Tank Assembly includes its pump, hose, and respective accessories. The isolated pump and hose design allows users to add on additional Tank Assemblies for different applications, eliminating cross-chemical contamination.

Milwaukee® is committed to improving productivity by providing performance-driven and trade-focused solutions so users can perform an entire day’s work on one battery system. The new M18™ SWITCH TANK™ Interchangeable Tank System is fully compatible with the entire M18™ line, now offering more than 180 power tool products.
