Description

Elevate Your Workflow – Start Spraying Carry Your Tank With Ease Adjustable Flow for Versatile Use Durable Design for Reliable Spraying Always Have a Spare Battery Ready Why did my new sprayer arrive with a little bit of water inside the tank? Each sprayer is water tested at the factory to ensure performance and a leak-proof design. Any remaining moisture means it passed strict quality control and is ready for use. I can’t find my nozzles and charger, are they missing? Your set is complete! All nozzles and charger are placed inside the built-in battery compartment on the front of the tank. Pull out the clear plastic cover to access the battery bay and retrieve all accessories. How do I fully turn off this electric backpack sprayer to stop spraying? This sprayer adopts dual control design. You need to turn off both the red power switch AND the flow control knob completely to fully shut down the machine. Only cutting off one part will not stop the water output. How long will the battery last? This backpack sprayer comes with two 2.0Ah rechargeable batteries plus a charger for easy recharging. The total combined runtime is approximately 3 hours and 36 minutes. No manual pumping required! Is the tank seamless and leak-proof? Will water get into the motor? This 5-Gal one-piece blow-molded tank has no weak joints. Its leakproof structure and drip diversion groove block water from the motor for stable, long service life.

    • Great for mobile car washing without a hose or bucket
Size: medium
We bought this portable water sprayer for my teenage son’s startup car washing and detailing business, and it has been a great fit. He can load rinseless wash right into the tank and clean several cars without dragging around a hose or bucket. The battery life has been strong so far, lasting through about 3–4 washes, and the sprayer has enough power for rinseless washing, wheels, and general detailing use. I also like that it comes with several different spray tips, so he can adjust the spray depending on what part of the car he’s working on. Another great feature is that the tank is sealed, so it’s ready to go anytime for the next wash. Overall, it’s easy to use, portable, and very practical for mobile car washing or detailing. Great product. ... show more

    • A sprayer that works well
Size: medium
The sprayer arrived ahead of time on was well packaged. I first tried it with water and everything seemed to work well. There are a variety of nozzle variations to choose from for many different applications. The 2 batteries are certainly helpful. The charger that’s provided, charges up the batteries in a very short period of time. I fill the sprayer with the desired chemical and put it on the floor of my side by side. Now I can spray while driving along tree rows and fence lines. I should of purchased a sprayer like this years ago. Only negative thing about the sprayer is that the green color makes it hard to see the fluid level in the tank. To address this, I marked the different amounts with a black felt marker on the outside of the tank. When I fill up the tank, I look inside the tank and I can barely see the marks. Kind of inconvenient but it works ... show more

    • COULD BE GREAT…BUT NEEDS TO BE DIALED IN
Size: medium
FIRST AND FOREMOST!!! TEST WITH WATER!!! PLEASE! DO NOT SKIP THIS STEP!! IT LEAKS OUT OF THE BOX! Did you test with water??? This could be great, but it needs too many tests. That said caveat emptor. If you are willing to take the time to dial it in, it’s a B- I had issues with leaking. After tightening a few fittings, it started to behave… then I had faith. I tightened it at the base of the handle, and it stopped the leaking there. Then top of the wand..Now my issue. I put the plastic nozzles/spray tips and they all leaked. I changed o-rings (that I had) and it minimized the leaking. Changed to metal nozzle tips and it helped a lot = plastic fittings are useless, until, I can figure out a mod. The volume/pressure knob/rotary knob is wayyyyy too sensitive = don’t bother. Note: this can be heavy for some when filled fully. So start 1/3, 1/2, 3/4 etc. See if you can carry a 5 gallon bucket without pain 😉. TLDR? This can be a great buy if you are willing to dial it in. I would not suggest to a friend because they would be texting me. I’d be willing to shoot a video if someone paid me 😆. ... show more

    • I Could Not Be Happier
Size: medium
I could not be happier with this product. Aside from how well it works, it includes an enormous amount of accessories. And even though the battery life is extensive, (we used it for well over an hour and it barely needed recharging) they have even included a spare battery. Their customer service is excellent and so is their product. ... show more

    • Seems to be very good quality, quiet and convenient!

Order came early from predicted. Sprayer was packaged well. I set up and tested the new sprayer and I am very pleased with its performance. In cact I am considering getting another one so I don't need to mix my weed killers with insecticides. It is actually enjoyable not having to pump often as with my old manual unit. ... show more

    • Let us spray!
Size: medium
I was looking for a cost-effective battery-powered sprayer, and the Seesii sprayer fit the bill. With a discount, I was able to purchase it for just under $79, which I felt was a good value considering the features included. The sprayer has a 5-gallon capacity and offers adjustable pressure up to 100 PSI, allowing you to tailor the output to different applications. It also comes with seven interchangeable nozzles, giving you several spray pattern options for various tasks. I was pleased to see that it includes a brass wand, which feels more durable than the plastic wands often found on budget sprayers. The package also includes two rechargeable batteries. The batteries are charged using a barrel-style power cord rather than a dedicated charging dock. Additionally, the sprayer is backed by a 3-year warranty, which provides some extra peace of mind. Overall, the Seesii sprayer offers a solid feature set for the price and appears to be a good option for homeowners and DIY users looking for an affordable spraying solution. ... show more

    • Big Upgrade over Pump Sprayers
Size: medium
I've been using a pump sprayer for years to spray a seasonal insecticide around my house. I spray around the bottom of the siding where it meets the foundation, plus all around the windows and lights and in the corners. If I don't do it yearly, bees build nests everywhere. Plus on my porch and deck, spider webs cover the areas and are difficult to clean. It takes about four gallons each spring. Once I got the hang of this sprayer, it really took away much of the time and effort. The wand that expands helped me reach up to higher places without me standing under the spray to reach. Less insecticide on my head is a good thing. It also enables you to adjust the pressure so when you don't need to reach those heights, it doesn't waste the spray and blast it back at you. As a side note, I didn't realize that the power switch on the backpack bypassed the pressure switch. The dial for the pressure clicks at the lowest setting, turning off the power. You can leave the power button off and just use the pressure dial to turn it on to the desired pressure. Just remember to turn it all the way down until it clicks to be sure you turn off the power. If you're always going to want full pressure, turn on the red switch. I'd recommend practicing with plain water until you get the hang of it. Another thing I noticed is that it has a handle on the fill cap. It may seem like a simple thing, but it's actually a thoughtful addition. The suction occurs at the bottom of the tank. When I was spraying on lower sections, I had to bend over and that pushed the liquid up to the top of the tank and it was just sucking air. I removed the backpack for the lower areas and held it by the filler handle. It was the only way to do it to get those lower areas. I didn't experience any leaks, and the battery barely moved even after all the spraying was complete. It also comes with different nozzles for different tasks. I will be using some of them soon to spray a liquid weed control for lawns to get rid of clover (I don't have any luck with the weed n' feed fertilizer on the clover). I'm new to this brand, and have been so impressed that I've now purchased four power tools and so far I find the value proposition excellent. Most things come with two appropriately sized batteries, a charger, accessories, plus a storage case. Even with these included extras, the cost is still below the "tool only" purchases for most other brands. I have a feeling I'll be buying more from Seesii. ... show more

    • I really like this backpack and all products they make
Size: medium
I tried this backpack out on my 10,000 square-foot lawn and I put fertilizer on it liquid and I bought a boom for it to spread it out wider. You probably will need a boom they sell them. Amazon for like $25 is worth it then I have an impact wrench and a vacuum cleaner and a chainsaw. I like this brand because they’re all interchangeable so far everything works well if you have a few professional maybe not but a regular DIY won’t work fine how many times you use a backpack a year how many times you use impact wrench maybe 23 times you rotate your tires maybe vacuum cleaner I use all the time for my car chainsaw works really well, but I’m not woodsman or cutting trees down for a firewood. It’s good enough for emergency. ... show more
