Rated 5 out of 5 by from Best Pressure Washer on the Market! Before getting this Ryobi pressure washer I had another brand pressure washer and it had nothing in this Ryobi one. This one is extremely easy to use. This will remove dirt and grime off of anything! When they say it is powerful, they mean it. I have used this to clean my car which allows me to save tons of money on expensive car washes. You never know how much you need a pressure washer until you own one. There are so many cleaning projects you can use this for like siding, driveway, deck, pourch, car, outdoor furniture, trash cans, swingset and many other things! I highly recommend this pressure washer!

Rated 5 out of 5 by from Great Pressure I owned a Ryobi Model RY80030 gasoline 3100 PSI washer with the Subaru engine for years. It has always had 1 pull start. I went to fire it up on 07/09/2017, it started and ran extremely well until I ran out of fuel. I refilled it and then had trouble starting it. I went and bought the equivalent but, with the Honda engine...it was doing a just as well if not better stucco removal job as my previous washer. The old washer was just binding due to the mounting bolts falling off of the base plate. I purchased the bolts/locknuts, new gun, hose, and tips and gave it to a family who is tight on cash. It, too, is now running strong again.

Rated 4 out of 5 by from Solid unit! I’ve had this for a month or so. Used it extensively this past week. Cleaned wood and concrete effectively. Easy to start. Adjustable head is nice. Concrete washer attachment (putchased separately) is quite convenient. My only issue is that on several occasions, after start up, the unit stayed in idle mode for a 30-60 seconds while I had the trigger depressed. With repeated squeezing of the trigger or holding the trigger down continuously, the unit eventually kicked in and high pressure water came out. This happened when the unit was “cold” or even after I had running a few minutes prior. A relatively small issue, but a bit of a nuisance.

Rated 5 out of 5 by from Great out of the box !! In the past years, I borrowed electric pressure washers from my buddies and they always under performed. After buying a new "old" house, I knew it was time to quit the mooching. I never bought anything from Ryobi but decided on this model based on the specs, reviews, Honda, etc. Out of the box this was excellent! Just read the instructions, prime the pump, etc. I am using it every-other-day for the past 2 weeks with no issues... the choke is adjustable, it starts on the first pull every time, the pressure nozel settings can be changed quickly and this beast is quiet! Great Job Ryobi (and Honda) I will consider your products in the future!

Rated 5 out of 5 by from Idle down is great! It really works well on idling up for pressure. It was easy to put together, gas tank will last about 30-45 minutes of pretty constant work. I do wish it had a drain plug for the oil, after first 15 hours of use I noticed the oil needed changing, had to tip it over to get oil out. I really recommend changing oil after breaking in to extend life of engine, change early and often.

Rated 5 out of 5 by from Works great I picked this up in a pinch at Home Depot. It's small, lightweight (was able to load it in the car by myself... and I'm not a big guy). I used it through an entire weekend, pressure washing for 6hrs a day with no issues. Pressure washed the entire house, prior to painting and bought a rotary attachment for it (not the Ryobi one) and used that to clean both the front and back driveways. Idle-down is a great feature and works as described. I ran it through multiple tanks of gas, sometimes running it until it ran dry. After refilling the tank it started right up. I can't really comment on "durability" as I haven't owned it long enough to say.

Rated 1 out of 5 by from Very disapointed After using about 5 hours the 3 bolts holding the pump sheared off. Store would not take it back. Ryobi sent me a new pump after about 10 hours of use the oil seal in the pump failed leaking oil all over. The shaft where the seal rides is very worn for only 10 hours of use. Once the motor quit and had no compression. Turns out the intake valve was stuck. I read somewhere that the pumps only last between 30 and 50 hours. It cleans good and has plenty of cleaning power but not made to prolonged cleaning like I sometimes need. 30 hr pump life?? I would have done better renting something than buying one of these.

Rated 5 out of 5 by from AWESOME TOOL!!! We purchased this thinking of all sorts of things we could use it for around the house. Our first project was to pressure wash the patio - brick and concrete. It was AMAZING - we were so happy with the results and how clean it all looked. Operating the machine was super easy and non complicated. We then took it to our warehouse and pressure washed the front of this 30+ year old warehouse and couldn't believe it was actually BROWN instead of TAN. What a difference this made!! That's the extent of our use at this time but we are planning several other cleaning times for things around our house and warehouse! LOVE LOVE LOVE this tool! Thanks Ryobi!
