18V ONE+™ 2 Gallon Chemical Sprayer
18V ONE+™ 2 Gallon Chemical Sprayer is rated 4.3 out of 5 by 18.
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.

Rated 4 out of 5 by from When I ordered this sprayer, I assumed the pump motor would be activated by triggering the spray wand. Instead, the pump is running under pressure the whole time, even without the wand being triggered. The new sprayer works great right out of the box, but I have to wonder how long the pump or other components will last with this design. I have a very large arsenal of Ryobi tools built up over the years that I am very happy with. I hope after 3 or 4 years, I can feel the same about this sprayer.

Rated 5 out of 5 by from Great addition to my Ryobi Tools My 4 gallon backpack model was too heavy for me in my old age, so I decided to get the 2 gallon sprayer. I already had many 18 volt Ryobi tools, so buying this made sense, as I can use my existing batterys. Now for the best part, I no longer have to stop and pump up a manual sprayer. I just pull the trigger and get instant results. Thank You, Ryobi

Rated 4 out of 5 by from Way easier to use than pump sprayer Bought this for spraying garden and trees. So far it has worked great with water and dish soap mixes but 8 believe it will work reliably with anything that is not a thick liquid. The nozzle adjusts from wide spray to straight stream. The pump runs non stop when turned on. It does not pressurize the tank and then run off tye pressure it just runs a pump when on with a trigger to start flow. The trigger on the wand also has a nice lock feature to lock it in and save your hand muscles from cramping after a few minutes. Makes it much easier to spray for long periods. The shoulder strap also helps with the tank weight when it's full. Buy the 2 gallon instead of the 1 gallon for the slight price difference because you can always just put 1 gallon of fluid in the tank if that's all you need and if you need more your not refilling as much.

Rated 5 out of 5 by from Sprayer Works great as advertised. Sure beats pumping a hand operated sprayer.

Rated 5 out of 5 by from Beats my Pumper Still new but so far so good. No way to use the back pack and turn it off and on without taking it off. Other than that I like thus far.
