## Description

The DEWALT 4 Gal. Lithium-ion Powered Backpack Sprayer has been built to outperform, outlast and finish the job in less time - with no more pumping. The lithium-ion powered backpack sprayer has Variflo technology which allows the operator to adjust the flow for multiple applications using specific nozzles for consistent spraying. This sprayer has a deluxe harness with wide, padded shoulder straps that fit snug across the torso and curve to the contour of the user's body. An adjustable hip harness assists with weight distribution, relieving burden from the user's shoulders. Multiple nozzle tips are included for versatility in both application rates and patterns and can be stored on the included nozzle clip. Equipped with a comfort grip handle and lock-on mechanism, this shut-off system can be easily operated with heavy-duty work gloves. It includes a 50 in. heavy-duty nylon-reinforced hose and strain relief system preventing the hose from kinking at the chemical exit point. This sprayer unit is also equipped with chemically resistant Viton seals throughout to withstand the effects of harsh chemicals. Whether it's for weeding and feeding, disinfecting, finishing concrete, eliminating mold or controlling pests - users are equipped for the Job. It's GUARANTEED TOUGH.

Review: Reading reviews before I purchased this, I was a little concerned because people said it was heavy. I have used both Solo and Echo hand pump backpack sprayers over the years as a Private Applicator. Honestly, I can’t say it was much heavier than either of those. I started by putting it on the back of my golf cart and driving around. It is top heavy and would fall forward if I hit a bump. Next I tried walking with it and it was comfortable and worked well. I used a DeWalt 8AH battery. I sprayed a total of 21 gallons of herbicide (5 batches and a clean-up) and there were still 2 of the 3 green lights on indicating it had only used 1/3 of the battery. I’m impressed with it and think I made a great purchase.
Review: I got this wanting to make spraying my planted trees and shrubs on my 2 acres. I was really worried it would be heavy but it’s not. I love that I no longer need to grab the handle and pump to get pressure. This gives even pressure at all times. I recommend fully.

- Heavy-duty nylon-reinforced hose effectively avoids kinking

### ⭐⭐⭐⭐⭐ Review
*by F***D on 30 December 2025*

This thing is AWESOME !!!!!! I can't tell you how much I love this sprayer. I have been spraying Permethrin around the house to kill off the bugs. This works great with little effort. When you fill it to 4 gallons it gets a bit heavy (think of it as a workout with a backpack :). It does have waist straps so that helps out a lot. With 4 gallons, I'm able to go around my whole house and spray to kill of the bugs. Works great. I would definitely buy it again in a heartbeat especially since many of my powertools are from DeWalt and use the same battery packs. Side note. When you get it, you might need to prime it. Getting a garden hose and blasting water into the vent (as suggested) worked REALLY well. After that, it works every time without priming it.
