Are you tired of your old sprayer leaking, wearing down, or just not keeping up with your tough outdoor tasks? Well, Milwaukee has got your back with their newly released M18 4-Gallon Backpack Sprayers. And guess what? They’ve listened to feedback and made some serious upgrades. Say goodbye to messy leaks, awkward pumping, and discomfort during long hours of use. These new sprayers are packed with game-changing features that will make your job a whole lot easier and more efficient!

Why You’ll Love the New Milwaukee Backpack Sprayers
Milwaukee has taken their already reliable M18 Backpack Sprayer and made it even better! Here’s a look at some of the key upgrades and why they’re a must-have for anyone in landscaping, agriculture, or construction.
1. SWITCH TANK for Ultimate Flexibility

One of the coolest features of the new Milwaukee sprayers is the Switch Tank system. This means no more manual pumping! Instead, you get to swap out the tank assemblies with ease for different spraying applications. Whether you’re working with pesticides, herbicides, or water for concrete cutting, you can change things up without the fear of cross-contamination. And the best part? No more leaks! Milwaukee has designed these tanks to be more secure than ever, so you can focus on the task at hand without worrying about spills.
2. Industry-Leading Pressure Control
Let’s talk about pressure—because the new M18 4-Gallon Backpack Sprayer offers up to 140 PSI of adjustable, constant, and instant pressure. Whether you need a light mist or a powerful stream, the 5-mode flow rate knob lets you customize your spraying experience. Plus, it delivers a vertical spray distance of up to 24 feet, making it perfect for tall plants or hard-to-reach areas.

3. Comfortable for Long Days
Anyone who’s carried a backpack sprayer knows that comfort is key. Milwaukee has designed their sprayers with padded straps, lumbar support, and a hip belt to make those long hours of spraying a lot more bearable. The optimized weight distribution reduces strain, so you can focus on getting the job done without discomfort slowing you down.
4. Durability for Harsh Chemicals
The new sprayers come equipped with Viton seals that offer increased durability against harsh chemicals. Plus, the dual diaphragm pump ensures a longer pump life. These sprayers are designed to withstand the rigors of professional use, meaning they’re built to last season after season.
5. Impressive Run-Time
With the M18 REDLITHIUM XC3.0 Battery (sold separately), the sprayer will run for up to 20 tanks per charge, depending on the mode you select. That’s plenty of spraying power to get you through a full day’s work without constantly needing a recharge. Whether you’re spraying fertilizers, herbicides, or water, you’ll be set for the long haul.

The Full Milwaukee M18 Sprayer & Water Supply System
Milwaukee is also offering a full suite of accessories to expand your system and maximize efficiency. Need a water supply for concrete cutting or coring? The M18 4-Gallon Water Supply Kit with SWITCH TANK (3019-21WS) has you covered, offering up to 60 PSI and up to 40 tanks per charge on the M18 REDLITHIUM XC3.0 Battery. You can even mix and match different tank assemblies, making this system as versatile as you need it to be!
Quick Tank Swaps & Easy Maintenance
Changing out tanks has never been easier thanks to Milwaukee’s quick-access latches. Plus, the wide mouth openings and strainers keep debris out of the tank, so you can fill and clean your sprayer without hassle. Say goodbye to complicated setups and hello to quick, efficient operation.
Want to Take Your Spraying to the Next Level?
Milwaukee has also released several sprayer accessories to further enhance your experience.
