No shortage of power

The PS60843 is a great pressure washer to own. It’s very quick and easy setup, and it does a great job of cleaning. Really glad I purchased this unit.

Easy to setup

I have not used it much but the setup and startup was really easy. It’s heavy but feels really solid. The gun and hose seem like they are much better quality than what came with my prior washer.

Powerful pressure washer

I bought this a little over a week ago and what a difference it has made. I've used it to clean driveways, houses, cars, garage floors, fences, and so much more. Absolutely love it and how much faster and more efficient it has made me.

Excellent power and fires up every time.

I purchased this unit one month ago to take care of ours and our families property and it doesn't disappoint. Very powerful and easy to use. I would recommend this to anyone looking and the quality is great.

Amazing power

This power washer is amazing. It’s so powerful. I cleaned all things in one wash. I don’t have to double wash and it comes with several different nozzles for convenience. It’s a great tool to have.

This is the second Simpson pressure washer I bought. I gave my old one to my nephew

My nephew needed a pressure washer so I let him borrow mine and while he had it, I was in the need of getting it back so I told him to keep my old one and I just went and bought a new one because I was so happy for the previous one

Lots of power

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.

Great News

The Simpson PS60843 is a beast. With 4400 PSI and 4.0 GPM, it cleans concrete, driveways, and heavy grime fast without having to linger. It runs smoothly, feels solid, and is clearly built for professional or heavy-duty use. Definitely more power than a typical homeowner needs, but if you want speed and real results, this pressure washer delivers.

Excellent Performance

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.
