ONE+ 18V Cordless Battery 4 Gal. Backpack Chemical Sprayer with 2.0 Ah Battery and Charger

I had the previous model of this sprayer which gave out two months after the 3 year warranty. I use the sprayer to maintain my own yard but use it every couple of weeks per my liquid fert program from the lawn care nut. Cons: The new sprayer has a longer tank the the previous model and lacks the frame found on the previous model. This impacts where to grab the sprayer to empty and clean out. Plus the frame had a backpack feel compared to the current model simply having the tank rest on your back. Some good points…. The new liquid pickup system is better integrated than the previous model with a U shaped tube. The new model has an adjustment dial that is an improvement over the previous model, but not necessary for my usage. Overall pickup of liquid seems better with the upgraded pickup system which is nice and also results in less low output sprays.

I bought it about a month ago based on my needs and my budget I choose this. I have about 10,000 ft.² lawn I checked gallon per minute for the Red tip that came along with and it measured 2 m 40 sec it’s fine spray nice n uniform at max pressure mostly for foliar application. I went ahead and bought some TeeJet tips - white flood jet measured 1 min 45 sec per gallon per minute and green tip measured 1 min 30 all at max pressure. With 3rd use crack on the hose that connects the tank n handle.

I bought my backpack about a month ago and the hose is already broke where it bends the most close to the connection. The plastic piece on the strap that adjusts also broke. The motor seems to be fine but for spending so much money I definitely think it should hold up better. I will never buy this brand again. VERY DISAPPOINTED!

I bought one of these about 2 weeks ago and have been meaning to write this review but ever since the first day I opened it, it leaks at the handle, and spilled all over the straps. I was really hoping it would workout, but I guess I'll have to return it.

This updated Ryobi sprayer worked very well with one EXCEPTION. The control dial will vibrate to the OFF position when the control dial is set at a minimum spray setting. On my first use of the sprayer, I had to keep my hand on the dial to prevent the sprayer from shutting off when spraying weeds using a minimum setting. This is not a problem when the dial is set to medium or high. See my simple fix for this problem I listed below with pictures. Ryobi needs to FIX this problem which would make this an Excellent sprayer. I had no problem with leaks or any other problem. I found the fill marks on the tank to be close to the correct gallon marks when the top of the square mark is used as a reference. I used 2 tank full (8 gallons, which is not heavy once you get the sprayer strapped on) of liquid to spray a very large gravel driveway which took very little time compared to using a 2 gallon pump up sprayer and did not drain the included battery much as when I put the battery in the included charger, it fully recharged within 15 minutes. Note the drain hole is recessed and is on the opposite side from the hose. I had no problem using all the liquid as long as I kept the sprayer level or slightly leaning to the left. If you let the tank lean to the right which happens as you are spraying and pulling on the hose which offsets the tank, there will be several ounces of liquid left in the tank. The instructions said the sprayer came with replacement seals. There were no seals included in the box and I contacted Ryobi and they had a set of replacement seals mailed to me. Note the seals are for the wand and spray nozzles, the pump is not user serviceable. The fix I did to keep the control dial from moving was simple. I punched out a thin rubber gasket with an O.D. of 1.5 inches / I.D. of .5 inches and put over the control dial shaft so the gasket was between the control dial and the tank (see pictures of dial and gasket). This provides just enough friction to keep the dial from turning but the control dial was still very easy to turn and does not interfere with the operation of the sprayer. From looking at how the sprayer control and the switch that controls the pump speed is built, not sure of another easy way to fix that problem other than modifying the actual control switch. Regardless, Ryobi needs to FIX this problem to resolve the issue with the pump turning off.

I bought this chemical sprayer few months back for my front and backyard. I first thought the battery (2AH included) won't last long but I was wrong. It lasted over 30 gal before I had to recharge the battery. The plastic body was durable which I believe it will protect from at least 10 drops on a concrete floor. Their were few downsides (but not significant to change my mind).... 1. Not so easy sprayer cap on the top. 2. Flimsy plastic sprayer rod. - If ryobi switch the rod to stainless steel or some other durable material than cheap plastic it will be great. 3. Not so translucent Plastic Water tank. - make it more clear so the user don't have to tilt or shake the tank to know the amount of water remaining in the tank. If the water tank was also detachable (the wash it) it will be a huge plus too.

[This review was collected as part of a promotion.] My sister began crying when she got these because it now makes her job and business a bit more easier and she also looks cooler and more professional when arriving to a new client. She is now more than motivated to get to work. She just started a new cleaning business and ryobi was on her wish list after reading all the reviews and on youtube.

[This review was collected as part of a promotion.] Purchased this to apply liquid fertilizers to the lawn, it works as it should, no issues. The fan tip sprayer is outstanding. The only problem I have with the unit, is that as others have mentioned, the gallon measurements on the tank itself is way off.

[This review was collected as part of a promotion.] Bought this to apply micronutrients to my lawn. Works great, best value I've found. Simple to use and assemble. Only negative is the plastic wand, it works well but wish it was metal. I did modify it by painting the gallon numerals on the tank (and the 18V symbol)

[This review was collected as part of a promotion.] First, Ill say this sprayer is a great value. It works very well, and needs nothing extra out of the box, except a bit of time to correct the measurement errors on the tank, which is kind of a big deal, since even the cheap sprayers seem to get it right. Without that issue, this could have been a slam dunk by Ryobi. Mine was off almost 1/4 gallon low at the 1 gallon mark, 1/3 gallon low at the 2 gallon mark, right on at the 3 gallon mark, and about 1/8 gallon high at the 4 gallon mark. This is going to the top of the molded rectangles around the numbers embossed in the tank. Both of my sprayers are identical in that regard, so I doubt I just got a bad example. After spending some time confirming this, I went back and filled using accurate measuring cups (1 gallon size), and marked my tanks to be accurate. Pictures added. One extra step that took some time, and really shouldnt be needed, except that the manufacturer couldnt be bothered with checking the tanks before mass producing them. Its still a good sprayer, but that takes away from the value.
