40V Cordless Battery 4 Gal. Backpack Chemical Sprayer with 2.0 Ah Battery and Charger

This is a heavy sprayer even when empty. Mine makes a loud high pitched noise when turned on. This unit is all plastic except for the rubber hose connecting to the plastic wand . This unit has no lower back support or lower belt to distribute the weight. There is also no drain plug to easily empty the container. The dial to adjust the flow is hard to reach when wearing on your back. The wand holder is also hard to use when wearing the sprayer. The battery does last a long time.

My property consists of 4 acres surrounded by dense woods with lots of weeds at the edge. So I’m no stranger to a backpack sprayer because I spray the edge for weeds to keep the ticks down. And this new Ryobi backpack sprayer is the best thing since sliced bread, and it turned my four or five times yearly back breaking chore into a quick, easy task. Plus it makes even spot spraying the yard for dandelions an easier task. I compared this sprayer to my old 4 gallon hand pump backpack sprayer, and the first thing you’ll notice is this thing is heavier. It weighs in at around 13.5 lbs. as compared to about 9 lbs. for my old one. But the excess weight is really no problem because the shoulder straps on the Ryobi are much thicker and more padded, so you really don’t feel the weight. With the Ryobi, it’s ambidextrous. You can use either your right hand or your left hand to spray, as compared to my old one where you always had to pump with the left hand and spray with the right. Very tiring process with my old sprayer. I measured the longest distance that I could get with a full battery and the adjustable spryer nozzle. It measured about 22 feet or more. Perfect for spraying those nasty poison ivy vines that grow up the sides of trees. The battery supplied was a smaller Roybi 2.0aH 40 volt battery, but I will never need a bigger one because this one lasts so long. The sprayer battery compartment would hold one of their bigger batteries if need be, but I sprayed at least 15 gallons of weed killer and it didn’t even make the battery drop one bar on the fuel gauge. The box listed more than 50 tank fulls on a charged battery. Wow! Plus, the rapid charger will charge it up in no time. The only issue I saw was the plastic on the bottom got a little scratched up from me dragging in on the driveway. Plus, I taped on a piece of foam rubber padding on the back of mine, because of the weight of a full tank, and the way it hung on my back, it kept digging into my lower back and it hurt bad. I’m searching for a better type of padding for the next use. Overall, this thing rocks.

I like to spray my weeds early in the season to try and prevent them from spreading before I can use the granular weed killers. I also spray around the house for bugs and have an area where moss sometimes grows and this works to quickly spray it. I may take this to the lake to spray the grass and weeds that grow in the gravel drive because it will be easier than loading up the pull behind mower sprayer set up. The unit is easy to set up and runs great. I docked a star because even running the sprayer on a low setting it sprays a lot of fluid. I typically use a gallon of weed spray on my yard and both of my neighbors' yards and it last 2-3 weeks as weeds begin to show and spray them. This setup used a gallon in the first use, but I am saving money because I can buy the concentrate and mix it myself more easily. The second time I used it I found a better slower flow, but that made the nozzle spray wider than I wanted it to. I may look at trying a different nozzle that allows less flow, but that means more expense. Besides the fast flow the unit isn't too heavy, it runs forever (2 uses and still on full battery bars), and the ability to lock-in the handle trigger is great. The pump does vibrate some on your lower back, but that should be expected and I didn't find it to be an issue. Overall I would suggest this, especially if you have large areas to spray and are going to save money mixing your own concentrates.

This RYOBI 4 Gal. Backpack Chemical Sprayer is a 40V Cordless Battery operated sprayer with 2.0 Ah Battery and Charger. On a full charge, you can spray UP TO 200 gallons of weed/pest control. We have a large back yard and my old backpack sprayer was a pump type which wore me out way before finishing spraying. Now with this one, other than stopping to refill the weed killer, it's a simple walk and spray. Wish I had this years ago and highly recommend it.

I will go over some specification's and information about this 40v Ryobi Backpack Sprayer and then share my experience. This package included the backpack sprayer, spray wand, 4 nozzles, replacement seal, 2ah 40v battery, 40v charger, and operator's manuals. If you buy this "tool only" you will not recieve the battery and charger. This Sprayer has a pressure rating up to 90 PSI. The tank can hold up to 4 gallons. The tank is marked in Liters and Gallons for measuring just the right amount of mix or liquid. The wand has an easy to squeeze locking trigger. You can lock the trigger pressed for continuous spraying or depressed to protect it from accidental sprays. There is a control knob on the side allowing you to turn the unit on/off and adjust the fluid pressure. The shoulder straps feel durable and well made. They have padding and a chest strap for better stability and comfort. The straps can be easily adjusted the same way you would tighten regular backpack straps. There are built in clips for storing your wand neatly. This unit has a removable filter bowl to keep your fluid free from debris while pouring it into the reservoir. The battery compartment has a cover to protect the battery from getting wet. This unit came with a 2ah battery but you can use up to a 6 Ah battery. Recently I have been looking at different sprayers because I will be pressure washing my wood shingles soon and wanted something to apply the sealer when I'm done. I am already into the Ryobi collection so I decided to give this backpack sprayer a try. (Only certain types of sealers can be used in sprayers). I have a couple different pump sprayers but they are alot of work. There are so many uses for this backpack. It will be great for watering plants where the hose doesn't reach, applying sealers, pesticides, herbicides, sanitizing, etc... Basically you can use this with any compatible fluid. I hadn't cleaned my shingles yet when I received this product so I decided to test it out with water. I could not believe how far this unit sprays. It made it up to the top of a 2 story house. I might not end up needing a ladder when I seal the shingles. As I was testing this sprayer out I noticed the birds made a mess of my car. I used this sprayer to rinse off my car and it did an amazing job. I Then walked around rinsing off patio furniture. Using this product was very simple. Add your fluid, turn the pressure knob, and pull the trigger. I also have a Ryobi EZ clean power cleaner. I would love to see a backpack like this that can connect to the EZ clean unit. If you need a sprayer and don't want to deal with pumping I suggest you try this unit, especially if you are already invested in the Ryobi system. They make an 18v and a 40v backpack sprayer.

[This review was collected as part of a promotion.] I was eagerly watching for this to become available after first seeing on videos from the 2022 lineup sneak peek, and it does not disappoint. I am able to spray my 18000 sq ft property using less than a 1/4 of the battery packs charge (4Ah was used). The included tips are great to start out with,but I will be upgrading to a Teejet fan tip. My only negative is the length of the sprayer wand, and the fact that it’s not stainless steel. Other than that, for normal use, this is a great addition to my 40V collection!

This is a fantastic four-gallon sprayer that is super easy to use because there is no tedious manual pumping. The pressure setting is incrementally adjustable to make it easy to get the right volume or distance desired. I used it to spray herbicide on the weeds in my lawn and did an excellent job. It has four nozzles (adjustable, flat fan, shower head, and dual so it is easy to get the spray pattern that is best for the job. The four-gallon tank is translucent and marked to show gallons and liters to show the fluid level and to help with the proper dilution of concentrated chemicals. The manufacturer states the 40-volt 2 Ah lithium-ion battery will spray 50 tanks on a full charge. The sprayer with battery weighs about 10 pounds, and when filled with four gallons of water-based chemicals the total weight will be over 40 pounds. Fortunately, the thickly padded backpack straps help make carrying this load bearable. There is a convenient wand holder on the right side of the tank which holds it while you wiggle into the harness straps. Using the sprayer is simply a point and shoot task. It took me about 30 minutes to spot spray two gallons of herbicide, and the LED indicator on the battery still showed a full charge. I am very satisfied with the performance of this product.

I have wanted a battery operated garden sprayer for a long time. Constantly leaning over and pumping and pumping to get some fertilizer liquid or weed killer out wears thin after many years. This Ryobi backpack sprayer may be overkill for some but the ability to hold as much as 4 gallons and not worry about pumping makes spraying almost fun. The unit is well constructed out of very durable plastic. The pump motor operates smoothly and the flow is powerful. Perhaps a little on the heavy side, this sprayer will be the one I use when I have more than a spot or two to spray.

This 4 gallon backpack sprayer has a large 40V battery to allow for substantial spraying activities without the pain of pumping constantly a pump type sprayer. It comes with 4 different sprayer heads, and has a secure clip set built into the tank to hold the wand. The only problem with that clip system is that it is so tight that you probably cannot reclip the wand without taking the pack off your back. The spray unit is actually fairly heavy to start, and with 4 gallons of liquid in it for apple tree or other fruit tree spraying, it will be a substantial weight on your back. The harness system is nice in that it has not only shoulder straps but a cross belly or chest belt to keep this in place during your spraying adventures. It has a variable speed switch on the bottom side of the unit, which you can modify the power of the spray simply by twisting the button higher or lower depending on your needs. The heavy unit is balances okay though with the bulk of the non liquid weight on the very bottom. The wand is also not a stiff breakable wand, but a moderately flexible wand so I doubt you would ever snap off the nozzles accidentally. The pump noise is minimal, and when you run out of fluid, the pump will continue to run until you turn the speed adjustment to the off position. I like this unit, and can highly recommend it to you.

Where has this been all my life? I have used many handheld 1-2 gallon pump sprayers and another brands pump backpack sprayer over the years. My biggest issue with pump sprayers is that I am stopping every 10 feet to pump and rebuild pressure. Not so with this Ryobi 40 volt electric 4 gallon sprayer. The 40 volt battery is much larger than the 18 volt battery that you find on many other Ryobi tools, so it has a lot of power (see photo). Simply pull the trigger and it sprays continuously. This is a game changer as I have a large yard and often spray for weeds. I am now saving tons of time from continuously pumping. I like how this sprayer comes with 3 nozzles for different applications. The 1st is a single hole sprayer, the 2nd has 2 offset spray heads for wider coverage, and the 3rd is a single spray turbo head with 4 holes which sprays water almost as quickly as a garden hose (see picture). The “turbo” head as I call it sprayed 2 gallons out in under one minute, and would be ideal for sealing concrete driveways quickly (see photo). I even was able to spray the mud off my car tires with it (see photo). The straps on the backpack are padded so even with 4 gallons it is not digging in your shoulders or being uncomfortable. I like that the On/Off power adjustment wheel is on the side of the sprayer and is easily reached while wearing it with one of your free hands. You can adjust the pressure of the spray by turning this dial as well (see photo). FYI once you turn the wheel to “On” the sprayer activates by the trigger on the handle then. I also like that the tank has 1-4 gallon markers on it so you know the level you’re at, and the tank fills easily from the top and has a strainer so no debris gets inside. Overall I am extremely impressed with this battery powered 4 gallon sprayer as it is saving me so much time.
