Questions & Answers

Is there a fix to prevent the pickup tube from floating to the top while in use?

Is there a fix to prevent the pickup tube from floating to the top while in use?
Asked by: DV
For things like that, I just disconnect the hose, put a very large nut over the hose, then put the pickup back on. The large nut (as big as you need) will then hold the tube down. I have even uses pieces of metal pipe over the tube and no way it will ever float.

Can this be used for spraying bleach?

Asked by: bmsksu
So sad...I was going to buy this tomorrow until I saw you cannot use bleach in it. I love Ryobi products, but I do professional roof and exterior cleaning, and I'd like to have something like this that would have viton seals that would be bleach safe for small things when it isn't worth priming pumps and unwinding a couple hundred feet of hose.

ONE+ 18-Volt Lithium-Ion Cordless 4 Gal. Backpack Chemical Sprayer - 2.0Ah Battery and Charger Included is rated 4.5 out of 5 by 448.
Rated 5 out of 5 by from Bought this as a gift for my mom as a Mother's Day gift for her since she does a lot of gardening... Bought this as a gift for my mom as a Mother's Day gift for her since she does a lot of gardening. It works great for the most part, and she says it's a great step up from the smaller handheld version I bought for her the previous year. Then she complained about it not spraying after about 2 months of use. After looking at the sprayer, I took the rubber hose/filter inside the tank off, and noticed some mold growing where the filter draws the water from the tank. Aside from it smelling badly, it was also clogging the hose, as I noticed the pressure returned to normal after I took the filter hose off. After cleaning the gunk out, the sprayer works fine again. I told her to clean it out and rinse it at least once a week to avoid more mold growth on the filter. So if it's not spraying, I recommend checking that rubber hose inside the tank.

I have a new respect now for military personnel in basic training running up and down hills with 40 pounds in their pack. It would help if this item was sold without the battery and charger. I must have at least a dozen lithium batteries and chargers plus a few of the old Ni-Cad batteries. People like me don't need the battery and charger included which of course increases the price.

Rated 5 out of 5 by from Awesome Sprayer! I purchased this sprayer after reading reviews on Home Depot’s website. I have pretty bad mosquitos in my backyard and didn’t want to pay a company $400 for their service plan to spray my yard 5 times over the summer. I’ve tried the bug spray that you hook up to your hose and have also used a hand pump sprayer and the Ryobi backpack sprayer is better than anything I’ve tried. Very easy to use and holds up to 5 gallons. I sprayed my whole backyard and it’s already saved me money. The spray power is incredible and I can spray under my decks at about 15 feet! If you’re looking for a great sprayer, spend the money because it’s well worth it. A flick of the switch and your off and running. No more manually pumping the sprayer every 30 seconds! This thing runs with power and all I do is lock the trigger! [This review was collected as part of a promotion.]

All I could do was laugh, because it works so well. I actually want to get another for my wife. I look like a Ghostbuster wearing this pack. It's so cool!!! Now to get into the product itself. It's a 4 gal chemical sprayer. 4 gal isn't that heavy to me. I'm a big guy. And I like to workout. But 4 gal can be extremely heavy for someone like my wife. Just use logic and caution when putting this on your back. Don't hurt yourself and blame the product. That being said, the straps are extremely comfortable and you can adjust them for a snug fit. The battery lasted the full time/process of me spraying my front yard. I believe I can use it a few more times before having to recharge it. The chemical sprayer has a metal frame to help with support for your back. That very same frame doubles as a stand for the sprayer. If you don't want to strap it to your back, there is a nifty handle on the top to carry it along with you while your work. All in all I am super satisfied. Have to grab one for my wife. She can't use mine!

It made my job a lot simpler than the last time I had to spray my backyard. What helped the most is that I can actually use it like a backpack. I was a little concerned with the lack lumbar support but it turned out pretty good. I loaded the tank full and it was not as heavy as I thought it would be. My main concern is a lower back injury I sustained in Iraq. As soon as I got comfortable with the weight and the strap adjustments, I was off to spray my backyard. This sprayer more than met my expectation for quality, ease of use and price. Once again Ryobi did not disappoint. I would recommend this unit to anyone in a heartbeat. Thank you Ryobi for another well made tool at an affordable price.

This is a powerful cordless sprayer that comes with the battery and charger. The battery is an 18 volt 2.0AH lithium-ion battery. The charger uses intelliport technology to charge the battery properly. With a 4 gallon capacity, this sprayer should be able to handle most yards without having to stop and fill up but I won't be filling mine to capacity since that would be too heavy. for me. It's nice that you can see the amount of liquid without having to open the lid to look in. The lid does double as a measuring cup for mixing your chemicals with water. This unit has a great amount of pressure that works well for most applications. It won't work for spot spraying in my rock garden as the pressure causes the liquid to splatter and I don't want to kill my flowers and shrubs so that area will still be done with the hand pump sprayer so I can control the pressure better. It's mounted on a sturdy frame that works good with the backpack setup but also has a handle if you don't want to carry it on your back and the frame works as a stand.

Rated 5 out of 5 by from Awesome Sprayer I previously used a one gallon hand pump sprayer to treat my yard. Yard is about 10,000 sq feet, took 4-5 hours to treat between mixing, pumping and spraying. The Ryobi 4 Gal. Chemical Sprayer did the same job in a one hour. Hundreds of fill ups turned into 4 fill ups of water and chemical mixture. Battery lasts well beyond 10k sq feet. Maintains consistent pressure throughout entire yard. Very pleased and would recommend to anyone that sprays / treats on a frequent basis. Only drawback is the pick-up tube found within the tank sometimes does not use all mixture in tank. Typically leaves behind about a 1/4 gal of mixture.
