DEWALT 190681 20V MAX 4 gal. Lithium-ion Cordless Backpack Sprayer Kit (2 Ah)

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.

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.

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.

Compared to my previous sprayer, this is game changer. Great battery life. Definitely worth investing in if you use a sprayer frequently over large areas.

Works awesome lot of power. It is REALLY heavy once filled with 4 gallons of weed killer but will do the work of a hand pump sprayer in a fraction of the time, can spray 4 gallons in minutes. Different spray head allow for every use.
