About Product Overview

This is a powered backpack sprayer, not a pump-and-spray unit — Milwaukee built it on the M18 cordless platform, so there's no hand-pumping to keep pressure up over a long job. The 4-gallon HDPE tank holds enough for a full pass on lawns, gardens, or farm plots, and the 48-inch hose plus adjustable spray tip give you control over reach and pattern, from a fine mist on foliage to a heavier stream for treating fence lines or larger areas.

With a vertical spray distance of 24 feet, it's got the reach to hit tall shrubs, trees, or hard-to-reach corners without extra effort. The padded shoulder strap setup is built for carrying a full tank through extended sessions, and the HDPE construction stands up to typical lawn and garden chemicals over time. Anyone running pest control, fertilizer, herbicide, or general property maintenance on a regular basis will notice the difference cordless power makes over a manual pump.

  • M18 cordless power source (battery sold separately unless included in kit)

  • 24 ft. vertical spray distance
  • Padded shoulder strap for backpack carry

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.
