18V ONE+™ 2 Gallon Chemical Sprayer is rated 4.6 out of 5 by 73.
Rated 5 out of 5 by from Great handy sprayer I got to admit this is a handy little sprayer. It really does job well without any effort having a pump. I never realize how hard it was to pump up sprayer this just makes it really easy to do. It’s especially handy for large jobs we are using up to 2 gallons at a time.I also think it’s a good value because the battery also fits all the Ryobi products which makes it really easy to share across multiple tools.

Rated 5 out of 5 by from Super efficient tool I just had this delivered. I have numerous Ryobi 18 volt tools along with extra batteries and 6 pack chargers. I just used the jigsaw and drill just yesterday. I love all of them. I am almost 73 years old and I enjoy woodworking. I have a shop where I make things as gifts for friends. This sprayer I just used to put out roundup around my flower gardens. It wasn’t bulky and had a great spray pattern. It was easy to fill and clean. I love it along with my jigsaw, router, saw, sander, impact driver, glue gun, brad gun and battery chargers and blower. RYOBI Iis a great product line. Prices are great and the products last. Get the sprayer you won’t be disappointed. .

Rated 5 out of 5 by from Great Chemical Sprayer I used this the first time after purchase today to treat my 1/2 acre yard. It works as described and it has much even spray than the hand pump sprayers I own. It will be a nightmare if I used my hand pump for the entire yard treatment. I think the 2 gallon is the right size for an average household. I do not need to stop pumping anymore and can just keep walking until all chemicals depleted. Refill is OK and wishes the hole can be bigger. sometimes I got some chemical on my cloth due to some minor leaks from the spray gun tube go to the tank. It seems not well sealed when it is full while walking but it is acceptable.

Rated 5 out of 5 by from A lot for the money I have purchased several pump up sprayers and they just did not work very well as far as a stream pattern was concerned. So I bought the P2803a, loaded it up and went out to the fence line that was difficult to reach. This unit easily sprayed to the areas that i needed to cover. The unit is quiet, I like the lockable trigger and the measuring cup on the side is very useful. Instead of all cheap plastic on the spray wand it is metal with brass fittings. neat thing is that the handle can be left in the holder and still use the sprayer or remove the handle and use the tube. Really well thought out product

Rated 5 out of 5 by from Easy to use ! I purchased this sprayer in March for an April 2nd Birthday Present for my wife. She has used it non stop for all sorts of applications, since ! Her favourite feature is how far she can spray. Both of us are very happy with this sprayer overall.

Rated 5 out of 5 by from No more pumping Wow I purchase this chemical sprayer a couple of weeks ago and it's the best. Cuts down the time it takes to complete a job easy to use love the measuring cup that is included and also the built in design for storing the handle when not in use. I has a stainless steel wand and brass tip great quality. Put this on your wish list this year.

Rated 5 out of 5 by from a real labor saver Replaces my 2 gal. hand pump sprayer...no contest! Produces an even, consistent spray pattern without repeated stops to pressurize a tank by hand pump. Enormously speeds up and eases the task. Great machine. I would like to see a screen added to the the 'replacement seals' package. This screen is at the tank end of the pick-up tube and will require clearing or cleaning to maintain sprayer performance. This maintenance requirement should be addressed in the Owner's Manual. This screen is about 3mm diameter and easily lost. Also, I really appreciate Ryobi's 18 volt +1 broad product line offings. Most manufacturers are busy making their most recent product obsolete while Ryobi is working to continue building on a solid product base. Well done and thank you.

Rated 1 out of 5 by from Stopped working after 3 months We used this unit to spray our disinfectant solution on our mats after Taekwondo training. It was good while it worked, but it just stopped working yesterday after about 3-months. It sounds like the pump/motor is running but the suction is lost.
