## Customer Reviews

### ⭐⭐⭐⭐⭐ Great Sprayer
*by D***D on September 2, 2025*

I have used this sprayer several times for various applications for my yard. I have a good-sized yard that generally requires me to fill the sprayer completely 3 times to cover the entire yard. for one application. The battery lasts for multiple applications to my yard. I typically use the wide sprayer nozzle for the yard which works well. I have also tried the long-range nozzle and the adjustable brass nozzle. They really do spray a long distance. I bought this sprayer based on the recommendation from a neighbor, which I appreciate. Now a landscaper bought one based on my recommendation. I highly recommend this sprayer.

### ⭐⭐⭐⭐⭐ Sprayer
*by A***R on September 17, 2025*

Works very well but cumbersome to put on

### ⭐⭐⭐⭐⭐ A high qualilty sprayer
*by L***D on June 8, 2025*

This sprayer has several features that I really like. I am comparing it to another back-pack sprayer I have, of an older design that uses a motorcycle battery. With this Dewalt sprayer, the battery is of the Dewalt ecosystem. The power button and volume control are easily accessible even when you are wearing the sprayer. A number of tips come with it, and they are kept in a plastic holder on the spray wand. Spraying is very even. The sprayer is somewhat heavy even when empty. Also, there is a removable filter within the tank. During my first use, I had about a half gallon of leftover Roundup that was at least a month old, and was a little cloudy. I mixed this with new water and concentrate to two gallons and went spraying, but when the motor started bogging down there was still about a quarter gallon left. The battery was still charged, so I believe the internal filter is clogged.
