## Description

Review: Dewalt Sprayer - Excellent! - I was initially skeptical about the price of this sprayer, but since I already owned a DeWalt drill battery, I decided to give it a try. Having used both 2-gallon and 4-gallon manual pump backpack sprayers in the past, I can say there is simply no comparison; this electric sprayer is a game changer. What normally takes me 45 minutes to complete was finished in about 15 minutes. The efficiency is incredible, as I no longer have to stop and pump every few minutes. While it has the weight you would expect from a 4-gallon backpack, it is manageable, and I found that filling it with 2 gallons was plenty for my needs. For those who prefer not to carry it, some companies make wheeled trolleys to pull the unit behind you. The unit is very quiet, features 10 spray settings, and produces an excellent spray pattern that can reach long distances. The build quality is sturdy, and the shoulder harness is extremely comfortable. I used a small 1.5 Ah battery to spray around my house, pool, deck, and pavilion, and it still showed a full charge when I was finished. I am so impressed that I am getting rid of my manual sprayers. If you are looking to upgrade your equipment (Man Card), I HIGHLY recommend this DeWalt sprayer. 10 stars.
Review: Great sprayer! - I had Dewalt 20v batteries from having Dewalt tools. So I thought I'd give this 4 gallon sprayer a try. Love it! No more pumping the sprayer. I can spray my entire property within 10 minutes easily with a heavy spray. It is very well made too. Battery life was still on full when I finished. So the unit is very efficient.

### ⭐⭐⭐⭐⭐ Works well
*by J***R on April 14, 2026*

This is a great sprayer. Easy to assemble, amazing battery life. No comparison to the small hand pump sprayers or the large backpack hand pump sprayers. Very comfortable to wear. Easy to clean and store. Looks like it should last for quite some time.
