Rated 5 out of 5 by from Why did I wait so long? Love this. Had a 1 gallon pump sprayer my entire life. Always running out of pressure and sprayer. Was always exhausted from pumping and replacing mixture. Was avoiding spraying util I bought this RYOBi. Now its so easy and effortless. I actually look forward to applying my ground kill and weed treatments .

Rated 4 out of 5 by from Cordless and easy to use handy and easy to use. Wish the Black tubing from the container to the trigger handle was more flexible. NOTE TO RYOBI: It would be nice if the fill cap, once used, could be screwed back on and drain back to container and not drip down the side of the sprayer. (yes, You can wash the cap out and then screw on, but it still drips down the side)

Rated 5 out of 5 by from Great Sprayer ! Purchased in November 2020, this is by far the best sprayer I have ever had the pleasure of using for all of my garden needs. Nice even pattern, powerful battery, and I love the fact that my combo kit came with an extra 2 gallon container. What a blessing ! I'll never go back to manual spraying again. What a time and effert saver this sprayer has been for me. I highly recommend this sprayer for ease of use and convenience !

Rated 4 out of 5 by from Great sprayer but terrible quality control! I bought this only to use for dormant spray on my fruit trees. About 10 minutes into first use, I felt my back getting wet. Upon investigation, I found that the O-ring between the powerhead and tank had been cut allowing solution to leak badly. Good thing I was not using a toxic substance! At that time I had not yet removed the powerhead, so this must have happened at the factory. Upon checking, I find a sharp burr on the tank opening that cut the o-ring. I sanded it down and installed the only remaining o-ring from the kit. Since I will be removing the powerhead after each use for cleaning, it is likely that I will need many of these o-rings. Contacting Ryobi has been a disaster, chat does not honor west coast time, emails and callbacks are unanswered. Great sprayer but not likely to buy another 18V tool. I am really happy with the 40V Ryobi tools I own, but this has been a customer souring experience!

Rated 5 out of 5 by from More useful than I thought! I was a little reluctant to try this sprayer which I received as a gift. When I did, I was pleasantly surprised. Holds just the right amount of liquid, easy to fill, adjustable nozzle, excellent sprayer power, easy to clean. More user-friendly than my 4-gal manual backpack sprayer from Stihl. Thinking about getting another for my vacation home.

Rated 4 out of 5 by from Makes things a little easier Definitely beats walking around with a hand pump sprayer. If you've got a big area to spray (for me, a gravel driveway) it's definitely worth it. Battery lasts quite a long time. 4 stars instead of 5 because the wand head requires you to swap out pieces to switch between fan and cone spray, where as other sprayers just let you turn a dial.

Rated 5 out of 5 by from This is a must have tool in your arsenal. I just bought and tried this sprayer and omg. Where have you been my entire life? This little machine takes the hassle out of the pump. It sprays continuously when you need it to. Still trying to figure out if it can shoot Clorox the info on that is vague. But nevertheless, it’s a purchase you won’t regret buying.

Rated 5 out of 5 by from Great price, well constructed Just purchased it and immediately tried it out. Couldn't be happier. No more shoulder and arm pain from the constant pumping of my older manual. With all my Ryobi tools and batteries, I never have to worry about having enough juice to finish any job. Love it.
