  • Backpack sprayer
Nice backpack sprayer, battery stays charged and has plenty of power
Reviewed in the United States on June 3, 2025 by Eddie Freeman

  • Junk
Horrible turned it on twice then it wouldn’t shut off. Everything was wire nuted together pump leaked and pump would not prime. Basically took it apart a bit connected with shrink tube and fixed the leaks. So straight out of the box if need a new switch wired in. Would not recommend if you plan on putting it straight to use. If bought plan on putting it on the work bench first not to mention the cap is pointless you shake it to much it will dump chemicals down ur back. ... show more

  • Cheap straps expensive sprayer
We were so excited to use this. We'll upon the first use the strap came apart. What's the purpose of having a backpack sprayer with one strap? Ridiculous! You pay your hard earned money and nothing is reciprocated.

  • Exactly!
It was exactly what I needed and it was well worth the price. There are so many more expensive models that accomplish the same things. I think I made the best choice for me. I’m trying to rid my 13 acres of poison ivy and oak and I didn’t want to have to constantly refill a smaller unit.

  • Shipped a broken used sprayer
Item arrived and appears to be pre used, I found grass and weeds inside the tank. The unit is unresponsive and battery will not charge. I did NOT order a used unit,Extremely unprofessional! And what a hassle to return…. I will not be getting another..

  • Now that's a backpack sprayer!
We have some property, and with property comes critters, weeds, spiderwebs high up, stuff up in trees you needs to spray, etc... This sprayer allows us to reach those places our other handheld sprayers cannot. It is high-powered, no doubt. Had a rechargeable-battery operated pump in the bottom of the backpack. The reservoir itself is huge (~4 gallons), and has a screen filter to protect debris from getting in there. Assembly wasn't the most straightforward experience. I mean, I've put together many handheld sprayers, but this one, as complex as it is, really didn't come with great instructions. It has an image with the parts exploded out. You'll have to guess what each part is actually called though. In the end, I used my experience in other sprayers to be-jangle it together.. but I will admit there are a LOT of extra parts left over. Like, A LOT. The kit comes with duplicate/extra items like extra washers, nozzles, spray rods, etc. In the end I selected using the metal spray rod for that upscale experience... it even extends out, quite nice, really. But there are a myriad/assortment of nozzles to choose from and various other things I don't know what they are for. Some instructions would be helpful. After assembling it, I put some water in it and donned it. Flipped the ON switch and let 'er rip. This thing has some pressure! Shoots the water easily 30 feet, probably farther than that too, but I didn't run it through the paces fully. I'm happy with the result. Wife said I look like I belong in ghostbusters with this thing, so I guess I know what I am going to be for halloween. All in all, it's going to be just what we need around here! ... show more
