Great sprayer, nice upgrade from manual pumps
Couldn’t be happier with this purchase. I upgraded from the manual pump model because I was tired of having to pump to maintain pressure and wanted my arm to be free while spraying. An additional benefit is that it seems to spray a bit faster so I spend less time spraying. I’ve used the sprayer multiple times to apply fertilizer and weed killer to my lawn. I’ve had no issues with clogging. The assortment of spray tips gives plenty of versatility for various applications. No signs of early failure, leakage, or anything else like that. Seems like it will last for years to come.

Good sprayer
One of the best sprayers I've owned, the straps and well made and work great don't know about the adapters the nozzle does all I need but the black one is handy when you want to know where you left off, it is pricey but it comes with battery and charger and it is dewalt

Good quality, and not too heavy.
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.

Doesn’t work
Dewalt does not manufacture or service this item. Besides the fact that it does not work the seller won’t take responsibility for their product. They are very difficult to communicate with, ask for the same information multiple times, and generally just throw up enough barriers until you give up. I own dozens of good DeWalt tools, but this is not one of them. Don’t buy it.

Works well and you can get parts.
My husband wanted this and he really likes it. Comfortable backpack harness and it works well. He wanted spare filters and we ended up calling The Fountainhead Group that makes the sprayer. Their customer service person on the phone was great. I feel pretty confident that if you need something for this you will be able to get it which is important to me.

Perfect for your Lawn Care business
I have had this for a week now. As a professional landscape/lawncare business owner, this is the perfect tool! Can spray 4000sqft of herbicide in a few minutes and refill and spray again. The single 2ah battery lasts a long time (don’t know the exact because I used one all day when needed and didn’t drop a single bar). If you are contemplating getting away from the hand pump, here is your answer. If you are like me and already have a bunch of 4 and 5ah batteries, you are set for days worth of spraying without ever having to charge a battery

You get what you pay for!
This product was/is well built (so far), your tank will come with residual water from them factory testing it. The only thing I will say is if you order online from amazon check your serial numbers and compare to the boxes, not a single serial matched any box of Dewalt products I purchased. Some boxes said made in Mexico while the sticker on the actual item (drill, etc..) will say made in Mexico or Made in China. I really don't care where it's made, I just want my products to match the serial numbers to the stickers on the boxes. Side Note, purchase the extra warranty. I'm Hoping to not need it, but its better to have it and not need it than to need it and not have it. This electric backpack sprayer is a beast! I had an issue with all types of insects in the garden and I spent countless hours trying to remedy the situation that I had... It was really bad, I almost gave up gardening (my little container garden) due to the aphids and ants and pill bugs etc... Watched several channels and took lots of notes and I had one last chance at it and spraying the neem oil worked! I tested it with about 1.5 gallons and was light on the neem oil concentrate however, next week when I spray I will be filling this thing up with 4 gallons and after I spray my garden, I will spray the entire yard to get rid of the mosquitoes in the area as that is the last insect I need to get rid of. I will only use this thing for the garden no herbicides will ever see the inside of this thing. This thing saved me so much time and effort and going through all of this made me respect anyone farming or gardening that much more. If you don't have a battery sprayer and you are on the fence with purchasing one, do it, you will not regret the investment. As far as where to purchase it, if you care about factory warranties and all of that find an authorized Dewalt dealer and purchase from them. I will be contacting the company and trying to figure out this little situation and I will update.

Not too heavy and very useful
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.
