Questions & Answers


How many gallons of gas does the tank hold?

Asked by Urmot April 7, 2015

The fuel tank holds about one quart.

The specs show 3 year warranty but the warranty from Homelite show 2 years. Which is correct?

Asked by etp1280 November 22, 2013

Thank you for asking, Etp1280. The warranty on this pressure washer is 3 years from the date of purchase. Our warranty covers for repairs of manufacturing defects. However, the Honda engine carries a 2 year warranty. I hope this helps and we appreciate your interest in Ryobi! -Keri

Will this remove paint from concrete?

Asked by AskingForAFriend May 27, 2015

I think it will remove it easily. The on board tip selector includes the 40 degree, 25 degree and zero degree. I'd start high and then go lower as needed but be very careful with the zero tip. Also, I'd recommend pre treating the paint with something like Goof Off or a latex paint remover to help soften it up.

What is it hard to pull the cable to start the power washer? I just bought it..

Asked by Bianca June 8, 2016

Like others have stated, pulling the trigger on the wand will release built-up pressure that causes difficulty in pulling the starter rope. As an indicator, you should feel/see the pressure shoot out of the sprayer wand once you press the trigger. It will be obvious. I also wanted to add that if you pull the starter but it fails to start, that itself will sometimes build up enough pressure to make pulling the starter rope difficult until pulling the trigger.

Is The Quick-Connect Nozzle Removable?

Asked by Urmot April 6, 2015

Thank you for asking, Djinn. The quick connect nozzle is removable so that you can use other nozzles with this pressure washer as well. I hope this helps and we appreciate your interest in Ryobi! -Keri

What is the ratio for the gas mixture?

Asked by Larry May 26, 2015

You don't mix the gas at all. You use plain gas, with no oil. It's a 4-stroke engine, not a 2-stroke.

I read in reviews that buyer said you could not shut the soap off when using. Is this true becaus...

Asked by Bo June 20, 2018

Yes, you can shut off the soap dispenser.

Is it normal for the engine to smoke a little after turning off? I just ran it for the first time for 15 minutes or so

Asked by Cbase May 24, 2020

Hello Cbase, Thanks for your question on the RYOBI RY80940B 3,100 PSI 2.5 GPM Honda Gas Pressure Washer. Yes, it is normal burnoff produced by the engine. Please be sure to check the oil and make sure you did not overfill. Overfilling the crankcase may cause excessive smoke and engine damage. Thanks for asking! - Eve

I bought unit but no nozzle end was included. Must I purchase seperately or should pressure nozzle be included???

Asked by Spitchinsc1999 November 23, 2017

store should get you one.

Is it safe to use bleach in this unit?

Asked by eldog March 23, 2015

Thank you for asking, Eldog. We do not recommend using harsh chemicals such as bleach, degreasers, etc. Using a chemical such as bleach may harm the seals inside the pump. However, if the use for bleach is needed for the job, you may put the bleach directly on the material and then possibly spray the bleach off. I hope this helps and we appreciate your interest in Ryobi! -Keri

works ok

I've had this pressure washer for over a year now and it seems to do an ok job. I haven't had any problems with it leaking. It does start fairly easily. My only problem I have had with this is that it idles down and almost stalls out after you let off of the trigger. It is kind of finicky sometimes. The wheels are nice and it is easy to roll around. It does meet my expectations for the sale price that I paid for it. Please hit thumbs up if this was helpful.

Does a great job of pressure washing BUT!

Pressure does a great job as a pressure washer goes. I’ve purchased a 15” circular cleaning for the driveway which works great with this pressure washer. I’ve also purchased the extension wand to reach up higher in the house which also works great with this pressure washer. My only issue with this pressure washer is the actual pump on this unit. I purchased it in September 2018, then in the spring of 2019, the idle down quit working (it would die why you released the trigger). They had to replace the pump as the idle down feature quit. Then the exact same issue again in the spring of 2020. It has had the water turned on and air ran out prior to starting. It has also always been stored in a temperature controlled garage so no freezing involved for the idle down feature to go out.

KINDA Awesome then....
Quality :

My wife bought me one of these late last fall. Since I know me, I decided to wait until spring before blowing the wood off the fence. I watched several you tube videos and yesterday, May 7th, was the Ryobi’s debut. It was awesome the first few hours!! Since we are all home and social distancing, the activity outside attracted my neighbors attention. With an audience, I nailed the sidewalk, driveway and side house stamped concrete with sweet results!! Then the pressure gun started leaking. A small amount at first. It steadily increased. Anytime I raised the gun above my chest, the leak would drip down my arm, soaking me. Last night, I tried to repair. I thought I had it fixed then today I began to wash my back deck and roof. Ten minutes in, the pressure gun began leaking again, a little at first, then it steadily became almost torrential. I had the wife go to a local hardware store and pick up a Max X Professional Max 4500 PSI pressure wash gun to replace. By the time she returned, I was soaked but finished. It was over 90 degrees both days so getting soaked wasn’t as bad as it could have been but an almost $400.00 pressure washer like this should NOT have any problems after just a couple hours of usage!! My neighbors were all impressed with the results after seeing and inquired if I would recommend a Ryobi pressure washer for their needs. I told them I would get back to them. I have my garage floor to do tomorrow and I want to see if I have any further problems. Impressed w the results but not the quality of the gun...

[This review was collected as part of a promotion.] I bought this pressure washer a week ago and it really surprised me in how good it is. I wash cars for a living and using my Ryobi pressure washer every day as my money maker, has changed how I work. I enjoy using it every day.

Good pressure washer .. but I have a couple of concerns that are not about how the pressure washer works but the operation and maintenance. I got this PW in 2017 and you have to be careful the pressure hose connected to the outlet tube it has a tendency to get stuck due to the pressures I guess. It's hard to remove and corrosion, the o ring rots also, where do I get the o rings that are at each end of the pressure hose. I'll have to start looking. Also be careful when transporting on it's wheels the inlet and outlet connections are near the ground and they need to be protected from curbs and ground dirt I cover the with a rag and secure them with my daughters pony tail bands. Keeps the sand out and protects them in storage . Other than the concerns you get a good washer at a reasonable price it cleans as advertised.

I was very pleased and satisfied with this pressure washers' performance. It was easy to assemble with the included hardware. It started on the first pull. It is not very loud on idle, but when you depress the trigger to clean the engine speed does increase to a level which requires hearing protection as it is in the 90 to 100DbA range, depending of course on your distance from the unit. At 3100 psi it has the power to clean efficiently and quickly. The price was very competitive compared to other quality pressure washer, and in fact the best price of any of them.

This pressure washer is AMAZING! I've owned multiple and had a friend over this weekend who has also owned and operated many pressure washers for both residential and commercial purposes and we were in agreement that this was by far the best pressure washer either of us had used. The 'IDLE-DOWN' technology is fascinating and is music to my ears! Anyone who enjoys using a high quality power tool or machine will LOVE that sound of the engine going from full bore down to idle - it's reassurance of your engine not being worked constantly thus saving the lifespan, only it is an audible reassurance. For the price, the power behind this machine is remarkable - it delivers a powerful spray with incredible precision and is very easy to use. The portability of this washer is fantastic! It rolls around wherever you need it to go, even WITH both hoses connected! And then it folds done when you're done! The soap reservoir perfectly dilutes detergent so you don't have to figure out ratios - I believe the ratio is dilutes is 20:1. It starts on the first try and doesn't need primed, just a quick choke, pull cord, return choke to run and VOILA! The motor purrs and idles down when not in use .. Did I mention how beautiful it sounds? When it comes to the actual PERFORMANCE of this thing, let me tell you that I am SOLD! I own a Ryobi Garage door opener, Ryobi backpack blower, Ryobi 40v weed whacker (also own the edger attachment and will be buying other attachments which connect super fast with their 'Expand-It' technology), and I must say that the weed eater held the trophy for most coveted Ryobi tool ... UNTIL NOW! This pressure washer spits out a perfectly regulated, evenly flowing 3100PSI which can be used in 1 of 5 settings on the INCLUDED attachment head - you don't have to buy any extra attachments. It has the 0°, 25° and 40° settings and two SOAP settings when you've got detergent in the SOAP reservoir. This machine is just overall such a solidly built, well manufactured piece of equipment. It has a Honda engine which you already know is going to outlast just about everything out there, and the warranty and customer service is top notch. The only piece of advice I can give you is that you 100%, ABSOLUTELY MUST BUY THE Pressure Washer Flow Control Valve! YOU WILL REGRET IT IF YOU DON'T!! Not everything can handle 3100PSI!! In fact, VERY FEW MATERIALS CAN! 3100PSI will rip apart wood (certain woods and from certain angles) .. I know this because it did so to a couple areas on my shed. I quickly reduced the pressure and was good to go! It reduces the pressure 70%-80% so it can drop 3100PSI all the way down to almost 600PSI. Attached are a few before and after pictures of my shed. I am painting it soon. The moss was CAKED on the roof probably well over half an inch. I also included a picture showing one or two fence boards i sprayed only, no wash or stain was used. Also pressure washed my car with the use of the Flow Control Valve! HIGHLY RECOMMEND!

[This review was collected as part of a promotion.] Bought this a month ago and I have already used it to prepare my house for painting. I have used it on my driveway and sidewalks (wow, very clean now.) And lastly I have used it on an old park bench that was black, not it has the original wood look again. A must buy - Thank you!

I bought this unit about few weeks ago and I used few times to make sure it’s working great and it won’t let me down. It runs very quite and strong pressure. 3100 PSI is good enough to clean everything outdoor including fence, driveway. It’s amazing. Thanks Ryobi.

[This review was collected as part of a promotion.] I had the 2900 psi and upgraded when I moved. For the price they are great! I will always buy Ryobi tools, as long as you maintain them they will last. Plus they are easy to keep track of, you cant miss the color of them...
