CRAFTSMAN 20V Cordless 4 Gal Backpack Sprayer — 2.0Ah Battery, Variable Flow & 21" Wand

The CRAFTSMAN 20V Lithium-ion 4 Gallon Backpack Sprayer is a battery-powered, ergonomic sprayer designed to deliver consistent, repeatable applications across lawns and hard-to-reach landscaping areas.

This cordless backpack sprayer combines a sealed battery compartment, variable flow control, and a 21-inch poly wand to make spot treatments and broad coverage faster and easier than manual pump units. Built on the CRAFTSMAN 20V platform, the unit ships with a 2.0Ah battery and charger, a heavy-duty hose, and padded harnessing so you can work comfortably while protecting the battery from liquid and debris. It’s intended for water-based chemistries such as herbicides, insecticides, fungicides and fertilizers used for home and light commercial lawn care.

How does the variable flow setting improve spray results?

The adjustable high/low flow control lets you match output to nozzle type and task, giving a consistent spray pattern without guesswork. That repeatability helps avoid over- or under-application when switching between spot treatments and broadcast spraying.

• High/low flow range for fine misting or heavier application
• Works with different nozzle types for grass, shrubs, and vertical surfaces
• Reduces wasted product by matching flow to the job

What features protect the battery and make maintenance easier?

The sprayer includes a sealed, water-resistant battery compartment and shroud that keeps the battery dry during filling and spraying. Tool-free cleaning access and a washable filter make upkeep straightforward so the pump stays reliable season after season.

• Sealed compartment shields battery from water and chemicals
• AC charger and 2.0Ah battery included; compatible with most CRAFTSMAN 20V batteries
• Washable wand filter and easy-access components for routine cleaning

How comfortable and durable is it for long jobs?

Padded shoulder straps, a supportive waist belt, and a lightweight chassis reduce fatigue during extended use. The 50-inch nylon-reinforced hose resists kinks and the 21-inch wand has a glove-friendly comfort grip and professional shut-off to simplify on-the-go adjustments.

• Padded harness and waist belt for balanced carry during all-day tasks
• 50" reinforced hose minimizes kinking and improves longevity
• 21" wand with ergonomic grip, lock, and filter for gloved operation

How long will one battery charge run and what coverage can I expect?

Runtime depends on flow setting and nozzles, but typical use yields up to four hours of spray time per charge and as much as 50 gallons applied on a single battery charge. That makes it suitable for medium-sized yards, perimeter treatments, and recurring maintenance rounds.

• Up to 4 hours of continuous spray time per charge (variable by setting)
• Capacity to spray roughly 50 gallons per charge under normal conditions
• 4-gallon tank for fewer refills between passes

Who is this for: The CRAFTSMAN 20V 4 Gallon Backpack Sprayer is aimed at homeowners, landscapers, and property-maintenance workers who need a portable, battery-powered sprayer for water-based lawn and garden treatments. It’s especially helpful for users who want consistent application rates, reduced physical strain compared with manual pumps, and a unit compatible with the CRAFTSMAN 20V battery ecosystem.
