Style: 3400 PSI
I was initially reluctant to purchase a gas-powered pressure washer because I did not want to take on additional engine maintenance. However, after reading several reviews and watching instructional videos, I learned that to achieve a consistent high operating pressure, not just peak pressure, it is ideal to use a reliable internal combustion engine to power the pump. I compared several brands and ultimately chose the Simpson 3400 psi model because it is made in the United States and provides the pressure level I need to remove mold and algae from my pool cage’s aluminum frame, as well as to clean my deck, driveway, and sidewalks more efficiently. So far, I am very satisfied with the performance. The pressure is significantly higher than that of my two previous electric washers, and the unit appears to operate reliably. The noise level bothered me at first, but I quickly adjusted. All components appear to be of good quality, at least as they look when new. In addition to the overall build quality, the larger wheels make it much easier to move the washer around, especially on grass. In summary, I am very pleased with this purchase, and based on my experience so far, I highly recommend the Simpson 3400 psi model for home use.

The media could not be loaded. I have had the Simpson Clean Machine 3500 PSI 2.5 GPM Kohler SH270 Power Washer for over two years now. I did have some issues at the very beginning. I had orginally ordered the first one which did not work, wouldnt turn over and the water pump was damaged. Called Amazon and the woman on the phone made the request for another one, as I really did want this particular power washer, very easy. The first one was picked up two days later and the next one came two days after that. Five minute set up. Connected it to a hose, filled the gas tank, went through each step listed, and the power washer started first pull, which it does 99% of the time even after it has sat for a long time. Now, you may have noticed that two parts on this power washer are not OEM. The Gas Tank (which came dented in right where the cap attaches but it wasnt an issue so it didnt bother me at the time), and the Air Cleaner Assembly, only because the power washer tipped in the back of my vehicle after I accelerated too fast. Both we very easy to fix. I decided to change out the gas tank because the cap has been hard to place back on recently and there was a slight crack where the dent was that most likely formed as a result of taking the gas cap on and off. Power washer still runs very well and I know I will get many years of service out of it. If I had to say anything truly negative about this power washer it wouldnt be about the washer. The service cleaner, that came as a bundle to the power washer, never worked right. It would get to full speed and then die back down immediately. I ended up getting rid of it just this year and I plan to get a better one sometime this year or next.

Easy to put together after taking everything out of the box, no issues either. Tested it out on one side of the house and it cleaned perfectly. Highly recommend so far!

Overall I’m satisfied with the power washer, it preforms as expected and appears to be good quality. I wish a 25 degree nozzle or at least a place to store one was included, but the description and pictures clearly show that it is not so this wasn’t a surprise. The unit came mostly assembled only requiring the handle to be installed and the engine filled with the included oil. The CRX210 took the 16 oz bottle. However, the assembly documents were lackluster at best. For starts they are spread across two booklets and two pieces of paper, all of which had repeated and contradictory instructions. This created confusion, it would have been easier to just ignore the instructions and assemble the unit based on intuition. For example, the paper and instruction booklet say to prime the engine using the primer bulb, but there is no such primer bulb on the engine which the engine manual reaffirms. Bottom line, it’s a good pressure washer and I wouldn’t hesitate to purchase again. Just throw away the instructions off the bat.

I was looking forward to using this pressure washer as Simpson is one of the top brands in the business. I received the pressure washer and everything arrived intact. It was simple to assemble and instructions were easy to follow. Added oil and gas and it was ready to go. Easy start up and was working great until it wasn't. Engine shut off and would not restart. I then discovered the spark plug wire had come unattached and when I checked it, the inside of the plug fell out. Unfortunately this could not be repaired and now I have to go to a service center for a warranty repair. A WARRANTY REPAIR AFTER 5 MINUTES IS UNACCEPTABLE. Now I have to wait 3 weeks or more for the repair. A NEW pressure washer that has to be repaired should be replaced and if not then a significant refund should be issued! This is the chance you take buying online and my advice would be to buy locally for this exact reason. Had customer service been authorized to replace the unit rather than repair the unit I would have no issues but now I am afraid this unit may give me problems for as long as I have it. **Update: I wish this was a happy ending update but as of today October 7, 2024, my NEW pressure washer is still with the Authorized Repair Center. After repeated calls, trips to the shop, conversations with warranty, the issue is still unresolved. I keep getting the same response, we are waiting on a part. No one has reached out to me to keep me in the loop during the process, the only way I get information is when I seek it out myself. I have been very patient but no one seems to care. At this point I just want a refund so I can go purchase another unit. I will keep you updated so that you may learn from my experience.
