I bought this for some little stuff around the house and I ended up helping a small company y with some weed spraying. I am floored as to how well this backpack works, the pressure it sprays at and the battery life. I think I went through at least 30 gallons if not more and the battery still had power left to spare. I like the user friendliness of it. Unlike the other sprayers with electronics in the handle, this one is a standard spray wand so if the handle or hose ever gets snagged on something and breaks I can very easily put any old generic hose and wand on it. I actually like spraying weeds now!!

It’s absolutely great! It’s late easy to Phil and you can adjust the spray without touching the tip. Perfect for deer repellent.

This might surprise you, it did me. I'm always a little skeptical, just my nature I guess. But I ordered this sprayer after a thorough research. I liked right off that it would work with my existing Dewalt batteries and the price was very good. I really didn't realize at first that this actually came with a battery and charger. Yes! Received unit on time, battery was already charged and ready to go. I put some water in it to try and also see what all the different nozzles did. Quite nice, and the pump has very good pressure. Another important fact is you can adjust the pressure while your spraying which is handy. Unit has a battery voltage guage on it as well. I will say it is a little cumbersome to make that pressure adjustment with it on your back but I'll get used to it. I have used it several times now with different chemicals. Sprayed the outside of house with a cleaner before pressure washing, sprayed some trees with insecticide and sprayed the concrete driveway with a solution before pressure washing . Worked great and the best part ..no more hand pumping, YAY! A note: I did spend $10 more and got the extended warranty, Just in case. Hope this helps someone..

Sprayer works well. Variable output works perfect and sprayed multiple tanks before charging battery first time. I did changeout the wand to a more solid one I had on hand.

Love this sprayer! Even if I just get a couple years out of it, it beats a pump sprayer all day every day. I have had no issues with my dewalt batteries with it. They work great. I haven't used the one it came with because mine are charged and ready to go. Would purchase this again.

I have several acres that I spray for weeds and it is a pain to use my old one-gallon pump sprayer. This spayer has made it SO much easier. Just some minor assembly (easy) and the battery arrived fully charged! I was using it within 10 minutes from opening the box. Great sprayer and highly recommended!

I had one sprayer before this, and this one is a major upgrade. The pressure is stronger, more consistent, and it gets the job done a lot faster. I’m able to cover more area without stopping constantly or dealing with weak spray output. The biggest win for me is the battery compatibility. I already use DeWalt batteries and chargers, so being able to pop in batteries I already own is a huge plus. It does come with a battery and charger, which is nice, but I really like that it also works with the DeWalt setup I already have. The backpack design is comfortable once adjusted, and the straps help when the tank is full. The larger size also means fewer refill trips, which saves time when I’m doing the yard, flower beds, fence line, or driveway edges. It also comes with different nozzles, so you can switch spray patterns depending on what you’re doing. Nice little bonus. Overall, this feels like a legit upgrade from a basic sprayer. More power, more convenient, and way easier to use. If you already have DeWalt batteries, even better.

Buy this and you buy an 88$ piece of garbage. thought this would be a good solution vs a hand pump. assembled it quickly, added water--the instructions are so rudimentary that it made me wonder if you are going to sell this--PUT SOME EFFORT into readable instructions. worked for 5 minutes then nothing i could do including all manner of CLaude and Chatgpt to get it going again. spare yourself the misery and buy from a known brand whose business model is to give a hoot about the quality they stand behind. not this endless stream of cheap plastic parts that break, cheap wiring etc... UPDATE: the company reached out and sent a replacement. Will try and hopefully this one will work. so I raised the star to 3 due to the company at least reaching out directly and offering a replacement (that Amazon let me do online in any case).
