Customer Reviews
Many customers and staff have commented on the quality of the Zephyr when they see it being used on equipment in our store.
It holds a lot of water and is easy to use plus it has a strong, steady flow and great battery life.
Great working sprayer, perfect for what I need it for.
Great backpack sprayer for home use. Easy to assemble and work around the yard.
Listen, I didn’t set out to feel like a herbicide-wielding superhero, but this backpack sprayer changed the game. The moment I strapped it on, I transformed from “tired weekend gardener” into “suburban vigilante armed with weed justice.” This thing is legit. First of all, it’s battery powered, which means no pumping. Just sweet, effortless spraying. It hums to life with a gentle whir, like it’s whispering, “Let’s go annihilate some dandelions.” And that’s exactly what we do. It comes with a bunch of fancy nozzles, which I assume are for people who read manuals or have nuanced spraying needs. Me? I use the 45° one. Why? Because it works, it feels right, and changing nozzles requires effort. The 45° angle just speaks to me. It gets into all the nooks and crannies of my yard like it was born for it. The rest of the nozzles are there just in case I ever want to feel like a scientist. The wand holder is a clutch feature. It’s like the sprayer saying, “Don’t worry, I’ve got your back—and also your wand.” When I’m done, I just pop the wand into the holder and strut off like I just finished saving the neighborhood from a pest apocalypse. And despite hauling around four gallons of liquid revenge, it’s surprisingly comfortable. The straps don’t dig in, it doesn’t slosh awkwardly, and I don’t feel like I’m training for a triathlon just trying to carry it. I’ve worn it for long yard battles without regretting my choices—or my life. So if you're looking to casually dominate your weeds while feeling like you're in an action movie montage, this is your sprayer. Just don't forget to recharge it... or your reign of lawn terror will be very short-lived
Zephyr Tool Only Battery-Powered Backpack Sprayer (4 Gal.) worked great with our already owned battery packs from two different tool manufacturers and they worked! I was very impressed with this flow zone Zephyr back pack sprayer. The fact that it is battery powered takes all pumping out of the job and gives you a nice even consistent spray over plants and a large area. The variety of nozzle choices included within the pack makes this sprayer very versatile in a multitude of applications. One of the best accessories included with this unit is the adapters that allow you to use other name brand batteries. Over all this sprayer has proven to be a fantastic addition to our gardening and critter projects.
