Review: Sturdy product and good quality - 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.
Review: This is a great power washer! - 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 desertcart 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.

## Questions & Answers

**Q: Those that have purchased this on amazon. who delivered it? ups or amazon?**
A: UPS delivered my first one with damage so bad it was unbelievable. Amazon delivered the replacement absolutely perfect in every way.

**Q: Mix oil and gas**
A: No do not mix the oil with the gas…gas goes one place and the oil in another.

**Q: Is presure adjustable?**
A: It is not adjustable…you can just buy a higher or lower PSI pressure washer, just depending on what you are looking for.

**Q: How come there are no reviews or anything on this machine? Also does it have a tank for soap?**
A: It barely has reviews because it is a newer model that is specifically made for Amazon with the Simpson/Kohler name on it. Also it does not have a soap tank but instead has a downstream soap injector, the soap siphon tube is included in the box all you have to do is stick it directly in the cleaning solution bottle of your choice and and then attach the black soap nozzle on the wand and it will automatically siphon the solution out of the container but only when the Black soap nozzle is attached to your wand.
