Milwaukee M18BPFPCSA0 18V Li-ion Cordless 15L Switch Tank Backpack Chemical Sprayer with Powered Base - Skin Only
The M18 SWITCH TANK 15 Litre Backpack Chemical Sprayer with Powered Base provides users an interchangeable tank design with no manual pumping. Designed to meet the needs of the landscape maintenance professional, the battery-powered backpack sprayer delivers instant, constant and adjustable pressure, up to 120 PSI, with up to 7.6 metre spray distance. The 5-speed pressure adjustment knob adjusts the pressure between 20 – 120 PSI for ultimate user control across a range of spraying applications. The 15 Litre Chemical Sprayer Tank Assembly features a dual diaphragm pump for increased durability and maximum pump life, while Viton seals increase durability against harsh chemicals. The tank also has a wide mouth opening for easy pouring and a strainer that filters out debris from entering the tank. The backpack frame includes wide straps and a handle for convenient transportation and storage. The 15 Litre Chemical Sprayer is comprised of two components – the SWITCH TANK Powered Base and the SWITCH TANK 15 Litre Chemical Sprayer Tank Assembly. The Powered Base includes the motor, battery compartment and REDLINK PLUS intelligence, while the interchangeable Tank Assembly includes the pump, hose, and wand. The isolated pump, hose and wand design allows users to add on tank assemblies for different spraying applications, eliminating cross-chemical contamination. It also provides users the ability to replace the tank assembly at a lower cost of ownership compared to replacing the entire sprayer unit. The Powered Base is also compatible with the 15 Litre Water Supply Tank Assembly (491628WSA).

I've used this sprayer on 3 occasions. Already the tank and the wand leak. This means that I get soaked in chemical and I leave trails of dead grass all over the yard each time I use it. If you look at the feedback on the American Milwaukee site this doesn't seem to be an isolated problem.

Leaks at the junction between the tank and pump. Really disappointing.

Used the sprayer no more than 5 times and it’s leaking chemical from the tank and wand. You end up covered in chemical. Would not recommend this product. Very disappointing considering the cost of the sprayer and not worth it.
