Simpson 4200 PSI 4G per minute is a professional and reliable, and easy to use pressure washer which comes in relatively small size which can be used and stored away simply without taking too much room. I recommend this product to anyone looking for trouble free, powerful pressure washer.

The first time I used this unit, oil began leaking from the pump. Tractor Supply stepped up and promptly replaced it with a new one. I have since used the new unit for approximately 10 hours total with no problems. I mostly use it attached to a 20" surface cleaner. I wouldn't go any larger than that. The only draw back is the filter at the bottom of the fuel tank is long and points straight up. So, while the tank has a little fuel in it, it will stop running. It's not a big deal. You just have to understand how it works. I would recommend it to anyone wanting a powerful pressure washer. I did add on a quick connect pressure guage, and it does put out 4400 psi. I dialed it back just a little under that. The only reason for the 4 stars is because of the pump leaking and the way the fuel filter is designed. Just fill it with ethanol free fuel so you don't have to worry about ethanol issues and you'll be fine. I only noticed the filter characteristic in the unit because I tried to put just a little fuel in it to test it out. I simply wasn't putting in enough. Also, people tend to skip the 5 star reviews to see what potential issues there are. Glad I bought it. Great price. Not a Honda engine, but the price is also lower because of that. At this time it has the most power for the money.

I bought this Simpson machine a month ago, and I’m really happy with it. It’s very powerful and leaves everything super clean. It’s easy to use, but at the same time, it’s great for reaching up to the second floor of my house without needing a ladder. I’m pleased with my purchase.

I’m very happy with this Simpson 4400 PSI pressure washer. It starts up easily, even for a gas unit, and delivers strong cleaning power for tough jobs like concrete, driveways, and equipment cleaning. The included accessories and good instructions made setup straightforward. The price was excellent for the performance and specs. The AAA triplex pump works well when maintained and gives reliable pressure. Overall, a great value and powerful washer that’s easy to use and worth the money!

From the second I unboxed this machine I knew it was going to be phenomenal. It’s a beautiful piece of equipment and it performs just as beautifully. I purchased this for my power washing business and it constantly outperforms its price tag. Stop looking and just buy it already.

I went with Simpson on the recommendation of a friend since he already had a Simpson. I really am glad that I took his advice. I already had a smaller power washer from another manufacturer but was having an issue with it and decided to purchase a new unit. I also wanted to purchase one that was a little more powerful. I couldn't be more pleased with my selection. The Simpson completed the patio cleaning job in half the time that it took me with my previous washer. Thanks Simpson.

We have been pressure washing everything possible since we got it. It cleans so quickly! Love it so far!

I bought it two weeks ago and have used it a total of two hours but so far it has exceeded my expectations. It replaced a 1980 Water shotgun

The unit works well, plenty of power and for a 4 gallon machine it cleaned well. I use it with a concrete cleaner and it does a good job.

Strong pressure and works great for cleaning muck out of wading pools and stains on concrete. Powerful yet easy to move and maneuver.
