Great versatility for cleaning a variety of surfaces

This pressure washer has all the power needed to clean large areas quickly and efficiently. The pressure can also be adjusted to clean surfaces that do not need the higher PSI.

Great product!

I bought this product and I'm very impressed with how well it cleans concrete surfaces. I plan to use this for many applications. I would highly recommend!

BEST PRESSURE WASHER OWNED

WE BOUGHT THIS 2 MONTHS AGO FOR USE AT A RESTAURANT. THIS PRESSURE WASHER WORKS GREAT FOR TOUGH STAINS!! WE USE IT FOR OUR DRIVE THRU LANES AND FOR EXTERIOR WALLS AND IT DOES A PHENOMENAL JOB CLEANING STAINS. DEFINITELY RECOMMEND IT!

Very Powerful

I only had it a few days but I can see it is a quality product My shop had a very dirty floor, dirt, grease, oil all ground in. The pressure washer and the floor scrubber did an excellent job cleaning years of grime. I also washed an outside concrete deck and two cars. The extra power 4000psi really makes a difference my previous model was a 2500psi Craftsman. simply no comparison So far I really like this machine and with a Honda GX270 it should last as long as my old Craftsman did. Easy to start is a very useful thing for an 80 year old.

Owner

This unit worked great, started with one pull and has a lot of power. The only problem with it is nose heavy and need legs to keep it from tipping over. I had it tied in my truck and it rolled over on its front, it took 2hrs to get it started again, the oil in the crankcase went in to the compression chamber and it took a long time to get it out to get it started. I still think it is a great unit, but it could use short legs to keep it from tipping. I will make some legs for it or move the motor back to help.

so far so bad

I bought this two weeks ago, it is my third pressure washer in about 20 years. I wore the other two out....I use them for my truck repair shop, using maybe two or three times a month on the average. The first time using this last week, I used it for about two hours and other than a leaky quick fit ( wand to hose ) it worked great. Now going to use it for the second time the pump kept by-passing for the first 5 minutes then it finally kept working. I used it for 30 minutes and shut it off for about 5 minutes and could not pull the engine to re start. Every time I tried, it would recoil jerking me along with it. For my sake I wish I had something better to say but at this point I don't.

very powerful

I bought this to prep some concrete parking blocks for repainting. I already tried a 1700 psi, electric power washer, but was not satisfied. This tool did the trick, it did such good job that essentially all the paint was removed, They look so good that I chose to leave them unpainted, thus saving me from this near annual task

Well built machine.

This is an example of you get what you pay for. This unit was more than I wanted to pay but I'm glad that I did because the quality is very evident. I had a cheaper unit for years and I was never happy with it so I'm enjoying the quality of the Simpson machine.

Blast the dirt

Easy to put together. I am very Pleased with the results. Cleaned up my semi trailer with ease and blasted the grease and heavy road dirt . I have had several power washers over the years and the Simpson has performed better than all I have had. I highly recommend this to someone who has some tough projects ahead

Outstanding Performance

I had an old and much smaller pressure washer. Cleaning the house was a real PITA. Now, with this super unit, it was much faster and the house looks great. Excellent engineering and construction. Well packaged, easy to follow instructions. Highly recommend! This unit is HEAVY. The guy at Tractor Supply loaded it for me. I used and engine hoist to unload it.
