I picked up this VAXMAY Battery Powered Backpack Sprayer for my father. He owns a landscape company and most of his work is on the "maintenence" side. He maintains yards, sprays, adds mulch and pinestraw, cuts back flowers and vines, sprays both weeds and feeds certain plants, sprays fertilizer, and a lot of stuff like that. My son works for him, and a few other people too. My mother and father (and our son too) live with us. My parents are getting older in years and while they are both still in excellent shape and health, we want them with us so we can help them and for them to be here to spend all the time they can with us and our children too, our son included. I'm an only child, so I'm all they have. So, any time I see things like this that he uses a lot for his business, or for here around our home and property, I try to pick them up. My father and my son use these every single week, multiple times each week. These backpack sprayers by VAXMAY are AMAZING! Both our son and my father really love this one! This one is a little more powerful in psi than the others he has, by about 20psi. So,this is a little stronger sprayer than his others. It has 120psi where his others are 100psi. This also holds 4.2 gallons of water, weed killer, plant food, bug spray, or whatever he may be using that day. Its awesome that this comes with a battery and a charger to use wuth it! Though other batteries are pretty universal to this as long as its the proper size. Ill get to that below. This holds a good amount of liquid and its VERY easy to assemble and to use! Both our son and my father have said its pretty comfortable to wear too. Backpack sprayers can be very expensive, and we are all happy to have found VAXMAY! We have a couple of their different Backpack sprayers and a couple of battery powered watering cans for our garden and chickens! This comes with 2 wands, 5 nozzles and it also comes with a rechargeable 2.6v battery and a really good charger! It is also compatible with DeWalt 20V and Milwaukee 18V batteries too! That is really handy because it allows you to have multiple charged batteries on hand if you have a larger spraying job, or more than 1 backpack sprayer, which my father does. The dimensions of this are 8" wide x 19" high and again, this one holds 4.2 gallons of whatever liquid you're using. Its really a nice size backpack sprayer! This also has a digital display that is easy to read to keep track of you battery level and psi. The battery snaps in to the lil compartment in the back, easy peasy! This is super easy and fast to assemble, or to get ready for spraying. This also comes with a really nice lumbar support, and that also helps the bottom of the tank to not make a sore spot on your lower back right there. This has 2 wands with it. A shorter one that is a 30 inch fiber glass wand which is chemical resistant, suitable for strong acids and alkalis, and its also corrosion resistant for more long term use. The 2nd wand is a 43 inch stainless steel telescopic wand that is ideal for water and more mild solitions. This wand is best for daily gardening type spraying. This also has 5 different nozzles for whatever type of spraying you need to do. It comes with a windproof nozzle, an F-type dual nozzle, a stream nozzle, a cone nozzle, and a fan spray nozzle. This bad boy has you covered! The handle also has an easy to use trigger lock on it, which is very nice. The psi is adjustable, of course. You simply turn the knob and adjust to where you need it. It goes from 0 to 120. This says you can spray 16 of these full tanks on one full battery charge, and my father has said that this does every bit of 16 tank fulls. This sprayer does have low voltage protection. It will auto shut off at 14 Volts and under. This also has a great motor on it that gives you 3800 rpms. The spray stream itself also has a nice consistent and strong pressure. This is a really great backpack sprayer for larger jobs! It has the battery power and the PSI, and it has nice & comfortable wide shoulder straps, and it has the breathable lumbar support, and breathable back padding. This sprayer delivers a balanced weight distribution in a great way! Its also very easy to see your levels as the tank is transparent with clear level markings. If you want, you can always go over those markings with a Sharpie or paint pen if you need them to stand out even better than they already do. Its also great that this comes with a 1 year limited warranty and 24/7 customer support. Bottom line - I have zero cons for you. None. My father has been using VAXMAY backpack sprayers for about a year now and he still has and uses the very first one he tried. He really likes these and this company! He loves this companies sprayers so much, when my mom was looking for something small and easier to water her indoor plants with, and we also wanted something for the more delicate plants in our garden, he had us both buy a VAXMAY small sprayer and we love them too! VAXMAY has been taking care of every member of our household and their own little personal needs and projects for a while now. This is a GREAT brand for outdoor tools like this sprayer. This sprayer is another great addition to their product lines! If you are in the landscaping or gardening business, own a nursery, or if you need one for any other at home project or job, you will NOT be disappointed with this bad boy! It comes with everything you need, plus a battery and a charger! This will 100% solve your spraying needs! My father, ny mother, my son, and my husband and I cannot recommend this sprayer more!

I recently acquired this VAXMAY battery-operated backpack sprayer for my backyard garden. Since there’s no available faucet in my fenced-in area, I have several sprayers, all of which are excellent and allow me to better compare the durability and features of this one. First, the sprayer appears and feels tough/durable. It’s made of hard plastic and has straps for carrying. As an older woman, I can’t carry this much weight on my already aching back. I can barely lift it, let alone put it on my back. If you are older, have back issues or difficulty lifting, this might not be the best option for you. Personally, I love this sprayer and water container. I don’t use it as a backpack, as mentioned earlier. Instead, I use it as a standalone watering system in my greenhouse. It works wonderfully. The heads on this sprayer are also excellent compared to the others I have. I have three, maybe four, VAXMAY sprayer wands and sprayers, and they are all top-notch. They are the best of the ones I own, and I love this one just as much. I might even prefer this one over the others. When you take the unit out of its heavy-duty box, which is wonderfully designed to protect the device when shipping, you’ll find that all the nozzles and battery charger are inside the water container. I admit, I was a bit of an idiot. I took the unit out of the box, examined its durability and some of its side functions, and couldn’t wait to fill it with water and start using it. So, I filled it with water and took it outside. Then, I started looking for the attachments, and it hit me—they were inside the unit! It’s a great place to store them during shipping or when you’re actually storing the product. As I usually do, I jumped right in and filled it up. Don’t do this. Lol No problem with the nozzles, etc., in the water bucket, but the battery charger was inside. One positive thing they do is wrap the battery charger in plastic, which makes me think I’m not the first person to do this. But the plastic didn’t protect it; it just filled with water and held the water inside the charger. I immediately took it out, drained the water, took the charger apart in half, dried the parts with my hairdryer, and let it dry for a couple of days. I haven’t tried it yet, but it is fully dry and hopefully it will work. If not, maybe I can purchase another charger. What did we learn here? Admire the tough durability of the unit, then OPEN THE LID AND TAKE OUT ALL THE GOODIES…I can’t believe I even did this. Overall, this is a really good unit. 1. It’s too heavy for me to carry on my already hurting back at 4.2 gallons which weighs around 35-36 pounds full, which may not be a lot for most people, but it’s pretty heavy for me. 2. It works beautifully, and it’s one of my favorite units. 3. It’s tough, durable, and well-made. 4. I definitely recommend this unit. It’s fabulous!
