M18 Switch Tank 4 Gallon Spray System

Milwaukee has brought an exciting new tool in 2019. The M18 Switch Tank backpack spray system is yet another innovation in battery powered tools. It features three interchangeable 4 gallon tanks, water Supply, concrete sprayer, and pesticide sprayer. A lot of thought went into the design of each part of this system. Although the tanks are similar they are each built for a specific job. This tool is great for anyone whether you’re a professional or a DIYer.

Being a pump-less spray system your tasks are going to be accomplished faster. Also with the modular design you can easily switch tanks without fear of contaminating clean water with pesticides. You can also have multiple pesticide tanks that utilize the same sprayer. In other words you can have different solutions that accomplish the same goal separated into different tanks.

How The Spray System Works

The Switch Tank system utilizes two components. The powered base and one of the three tanks, depending on what task your tackling. All three tanks have a 4-gallon capacity. Each tank is also built from the ground up to handle it’s designated task. For plain water applications, you have the water supply tank. Secondly, for concrete applications the concrete tank. Finally, the pesticide tank. Any combinations of these tanks can be quickly changed. Each sprayer features a spray lock on and off.

This system allows you to take care of weeds before concrete work, or spray off with plain water excess pesticide from surfaces. This system is truly innovating, from conception to delivery. Knowing how well Milwaukee tools are built we have no doubts this will be a solid tool.

The Water Tank

That amounts to 48 gallons of water on a single charge, you can throw on a bigger battery and get even more gallons out of it. This tank features a 10 foot hose with quick connect,  a large mouth with filter for filling, and a dual diaphragm pump.
