  • Holds lots of fluids and has long battery life
Color: Green
I got this 3 gallon backpack yard and garden sprayer to replace my manual 1 gallon pump sprayer. It seems that every time I would go to spray for weeds, I would have to refill the tank 2 or 3 times. Then, I would have pump, pump, pump to pressurize the tank to make it spay. Well, now those days are over. With this new tank, I can put enough solution in the tank to pray my entire yard in one go. Additionally, the battery pack keeps the backpack spraying the entire time. One of the things I really love about this new backpack sprayer is that it comes with 7 different types of sprayer heads. There are ones for streams, cones, mist, and even one with dual heads. There are two downsides to this backpack sprayer. First, when the take is completely full it does get heavy. It is good that it is a backpack so I can use my full body to support it. Second is that it can be a bit challenging to get the backpack on my back. It helps to have the backpack on a table or something to get it off the ground. ... show more

  • The Mayoki 3-Gallon Battery-powered Backpack Sprayer for a Petite Gardener
Color: Gray
I Can Garden Like a Pro using the Mayoki 3-Gallon Battery-Powered Backpack Sprayer I am a petite, DIY designer and was looking for a good sprayer for my sizable rose garden. This sprayer was an investment and I may have underestimated my capabilities to use it to the max. I noticed the sprayer was heavy, primarily due to the battery. The adjustable straps required some trial and error to fit my small frame. The package included a variety of nozzles and two spraying rods, all equipped with intact 'O' rings to prevent leaks. I was disappointed to find the sprayer handle damp and filled with a clear fluid, suggesting it might have been a returned item. I used the sprayer to apply mold deterrent around my pond. I also used it to apply an alcohol solution to the undersides of some plants to combat spider mites. The 3-gallon capacity and battery operation reduced the need for refills and tiresom manual pumping. The removeable filter cup inside the container prevented nozzle clogs. The battery life was good, lasting through several full tanks and recharging swiftly. The on-off buttons are located on the back of the unit. The handle's plastic catch feels flimsy and may not endure a full season. While the instructions were comprehensive, guidance on the top and bottom strap attachment was lacking. For serious gardeners and DIY enthusiasts, this sprayer is a convenient tool and time-saver. It's a worthy investment. Just ensure you have adequate storage space for the unit and its attachments. ... show more

  • Excellent new garden toy!
Color: Green
This is excellent for spraying (non-toxic) vinegar/dish soap week spray around the house. It sprays a lot and has several different tips for spraying options. My 10yo wears it for yard chores and it really speeds up the process, making it painless for all of us. I’m very pleased with this product!

  • Using on my garden; very convenient
Color: Gray
I got this to use to spray my veggies. I tested it out this winter to see if it works. It works very well. I did not fill it all the way, but it would be awkward to put onto my shoulders if it were completely filled. I will probably set this on top of one of my pens in the barn and bring my arms through and strap it. I love that it is battery powered most of all. This will make my spraying jobs very easy. ... show more

  • Pretty nice
Color: Green
Waiting until spring to use this and will update when I do. But it was very easy to put together, and it seems very sturdy. The only thing I would change are the straps. They seem a little cheap but as long as they don’t break on me I’ll be happy.

  • Much Better Than a Manual Sprayer
Color: Gray
I love that I can use my existing Dewalt 20V batteries with it. It's so much better than the hand-held 2-gallon sprayer I was using before. It's way easier to carry as a backpack, and I don't have to constantly pump it to maintain pressure. It's so much more efficient and less tiring. The 3-gallon capacity is perfect for most of my garden jobs, and the battery lasts a long time. ... show more

  • Missing Part(s) - All is fixed
Color: Gray
Update 12/30/24 Awesome customer service, A+. Seller reached out for some information and took care of everything very quickly. Recommend the seller and the product. ******************** Unfortunately, I did not receive the wands in the package. Everything else is functioning and in good condition. The included battery does not appear to take a charge on a DeWalt charger but works in the included charger. The tank unit DOES accept OEM DeWalt batteries, and I tried a 2AH battery and function tested the motor. There is room for a larger AH battery in the battery bay. The fit was tight on the battery connection rails but I'm sure that will loosen up in time. Product package box did show some damage so maybe the wands escaped prior to delivery. Connections look pretty standard so I'm going to check if some parts I have around will work. 4 stars if I had received everything. ... show more

  • Being used with an environmentally friendly bug peppermint spray
Color: Green
This is being used as a peppermint spray for bugs and spiders around the home and in the garage. It does come with a battery and pack so you have everything you need. It has multiple nozzles, which makes it really nice and it’s large enough to spray the house multiple times. The container is built heavy duty and this a genuinely quality sprayer. Instructions are included and everything is organized in the box. I totally recommend and I can also update this review I the future to review how it works over time. This is a good buy. ... show more
