This is only review but the pressure washer is much better than the previous system that I owned. Plenty of power a bit awkward to move around. They might as well put a third wheel in the back or four wheels but this thing will clean anything. Oh yes, and I wish it was just a Key start for that amount of money it should be.

Dealt with a few pressure washers. First time having a Simpsons, and this cleans extremely well. The 4.0gpm makes a lot of difference and its pressure stays consistent while also efficient on gas consumption. Overall very impressed by this machine. Well worth every penny if you want the job done right while also with speed.

Limited use (6-7 hours), but so far, I am very impressed. Extremely well built and solid! Starts on the first pull every time (so far). As for performance, it is a beast! If you weigh less than 180 pounds, beware. This thing will lift you off of the ground! I bought the Simpson 20” surface cleaner too, and it is fantastic. I wish I had bought this long ago.

Just got this yesterday and used it today. It worked as expected , awsome. After unpacking ther we’re no scratch’s or dents on the unit. Assembly was quick and easy. Everything was in the box. I owned a Simpson alh4240 for around 7 years. I build houses and used that machine to pressure wash all the houses. And many of our driveways are over 100 feet long with massive covered porch’s. Not sure how many houses it did but I’m positive it’s at least one hundred. Many took over 4 hours to do . Looking forward to many years of service from this new machine. Great job Simpson. I had no reservations with buying another Simpson made product.

I purchased my pressure washer about a month or so ago and it was the best purchase I made this year. This pressure washer has so much power and I’m able to do so many different jobs with just this one machine. I highly recommend this to anyone who’s serious about exterior cleaning.

I got this for my side hustle and it’s amazing. I had a 2600 psi 2.5 gpm pressure washer and it was nowhere enough. This is plenty. It’s so much more reliable. Makes cleaning concrete and siding so easy. Couldn’t love it more! Simpson did a great job making sure the customer had everything they needed.

Opened the box today, easy set up, had to put in engine oil 10W-30. Crankcase oil already add before boxed. Very heavy duty hose included 50 ft. I bought addtional 100 ft extension. I have a very large driveway and basketball court and due to the 150 ft of washer to wand hose, I didn't have to move the power washer once. Zero degree apeture attachment (red) allowed me to reach mud dauber nests 23 feet up in entryway.

I have used my new unit for the first time yesterday and found it to be very powerful compared to my previous units. Overall, I am happy with the machine. There are a few items that I believe that they could improve on. The markings for the choke position and fuel on are very small and would be better if they were marked larger and bolder. My previous unit had an idle down feature when the trigger was off that was very nice because there wasn't the same urgency to have keep the the water flow constantly moving and it also reduced the kickback when the trigger is pulled. An additional feature that would be nice is to have would be the ability to add an electric start as an option.

I recently bought this for power washing driveways and walkways. The power is a noticeable difference over my 3200 PSI unit. The only issue I have not figured out yet is the soap hose. When the unit is off, the soap is pulled through the hose. However, when the unit is running, no soap appears to be pulled into the unit. Not sure if the problem is the unit or something I am not doing correctly.

I am having to get warranty work done for the second time in just over a year losing over two months of operation and time/money taking to service center that is close to an hour away. My friend purchased the same unit around the same time (April 2025) and has had his fixed once already for the same exact reason.
