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. ... show more

I have a Simpson Cleaning CM61118-S Clean Machine!! Just purchased it and used it for first time I'm impressed it worked good. Pie is small tho worked good just took a bit longer. But the pressure washer is a buy. I used to use a hydrotec commercial pressure washer with heat for 8years and this compares to it. ... show more

    • Nice Pressure washer.
Style: 3500 PSI
I loved this item it works great and cleans great. The floor cleaner is amazing. My only bad thing to say is that when I got it. It had a damaged tire that would not hold the air but thats not the pressure washer fault. Great solid item.

ZERO STARS It worked great for one hour. Next day, would not start, called Simpson customer support and tried what they said. Still won’t start, Amazon WILL NOT take this back. Neither will Simpson. They will not replace or refund and only offer a repair if it’s a pump problem. $400 useless pressure washer!! Never again!! ... show more

    • Great pressure washer. light enough to carry up stairs but powerful. Needs Simpson QA attention
Style: 3500 PSI
Great product. Dependable engine, but Quality assurance on assembly was lacking: Got it shipped, and part of the water receptacle was bent. I needed it, so I used it. The wheels fell off because they had failed to put on the 2 clips to hold each one in place -- I'm assuming they're clips, so I pulled it out of the mud and wired them in place. On the exhaust muffler, one hex head screw was missing -- still is after 25 hrs os use -- but with all that, it is still a strong, dependable unit that I would buy again. I never attempted to contact Simpson since I work remotely and knew whatever was awry could fix. I'd give it 5 stats except the above... ... show more

All in one package for cleaning your driveway. Took me 4 hours to clean a 400ft.driveway, but looks fantastic! Only one very small complaint...wish it had a little longer wand. Need about another 6 inches and my back would have been happy!
