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. What liquids can I use with this sprayer? Use only water-based solutions compatible with the sprayer. Do not use flammable, solvent-based, strongly acidic, alkaline, or corrosive liquids. Rinse the tank, hose, and wand with clean water after each use. 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.

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.

Backpack aspect is terrible
Size: medium
In less than 3 months one of the shoulder straps dry rotted and broke I was going to give 2-3 stars because only one strap broke, but by the time I sprayed what was in there, the second strap also broke. I guess that is OK because it is really uncomfortable, like strapping on an hard box. Other than the “backpack” aspect, the sprayer seems to work just fine. I do flush it with water every time I use it.

Good sprayer for the price
Size: medium
Well worth it. For the price you get a good product. The pressure of the spray was above expectations and the metal wand with a brass spray tip is a nice feature. I purchased this sprayer to apply insecticide and weed killer. I'm not sure how to compare to professional grade but this feels stout and the build quality seems great. The plastic is thick and ridgid. It comes with extra replacement gaskets and a number of different spray heads. It also comes with 2 batteries. I just sprayed 2 gallons of insecticide around my 1800 sqft house using around a 1/4 battery. I recommend doing a test run with only water to make sure everything is tightened up and to get a feel for using it. There was a little leakage around the wand extension that needed tightening while I was using the sprayer. Overall I'm happy with it.

Almost a great sprayer
Size: medium
Bought this sprayer to replace a manual pump backpack. I used it for the first time today. Put just water into the unit to get used to how to adjust the unit. Overall a great experience. 8m not sure the life span of it but for the price I hope it lasts awhile. Sprayed 2 different chemicals in a batch of 3 gallons then 5. When I was done the battery still had full bars. Alot easier that having to pump and spray at the same time. The reason I dropped this to 4 stars is no clear strip or good way of seeing how full the unit is. Plus just having liters only for us US folks is a challenge. I ended up taking out the filter screen when filling and holding my finger where I wanted to fill up to (on the outside). Besides that I like it do far.

Works well...think and do
Size: medium
First, everyone should understand that a gallon of water weighs about 8.3 lbs. so it should come as no surprise that the unit plus water is going to get heavy. Solution is to just not fill it up beyond one's physical capabilities. Second, it would be nice if the measurements on the side of the tank were in gallons vs liters, but easy enough to solve by using a gallon container to fill the tank and marking the outside at the gallon, 2 gallon, etc. level with a permanent marker. Yes, it would be nice if the tank was clear, but you can still see through the blue plastic well enough. Finally, regarding all of the complaints about leaking joints or connections...do yourself a favor and just try tightening them. That did the trick for me. Appears critical thinking is the other national deficient. So far for me the sprayer has worked well with no issues so I would recommend it.

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.

wo units, two failures — no power on one, no pressure on the other
Size: medium
Please see the video. This is now the second unit I’ve tried, and both arrived DOA in different ways. One had no power, no response, nothing. The second powered on but had no pressure and no spray at all. At this point it’s clear there is zero quality control happening before these are shipped. Very disappointing experience and a waste of time. Not recommended.
