Strong and reliable (detailed review over the year)
Wanted to wait for some time to pass before making a real a review on my pressure washer. Purchased in sep 2021 and it’s now Jan 2025, so I have used it for 3 warm seasons since I only use it during the warmer months in PA. Did A LOT of researching before pulling the trigger on getting this unit. Some might think it’s expensive for someone who may only use it for home use and not commercial, but it’s perfect and reliable! I wanted something that would be versatile and beneficial with all projects. I always do the recommended maintenance and when storing for winter I winterize it. Maintenance is key for anything and I believe taking care of this will make it last for years of use. Main selling points for me and things I like: - CAT AAA pump, Honda engine, warranty, GPM, heavy duty but “light weight” frame/wheels, and being able to not worry about damaging the pressure washer if you release the handle while it’s running (not something I do often but know that’s a big no no when it comes to other pressure washers that don’t have the feature to allow this. High PSI and also the ability to lower the rpm’s to use it for lighter duty tasks. My complaints over the years: - The rubber feet that come with this unit are garbage, plan on replacing them with bigger and better feet because these ones will not last and the pressure washer will walk around on you. - I wish there was a better design for changing the oil, it’s a pain in the butt but with the right set up it wouldn’t be a big deal - It a little awkward when wheeling it around but it’s not a big deal and is only heavy if you are picking it up by yourself to go up stairs or things like that. Overall I would highly recommend this and would purchase again! Hope this helps you :)

Powerful Machine and Great Customer Service!
This was originally going to be a four-star review but...(read on)... I bought this to replace an old Husky electric pressure washer I found on clearance and the big orange store about fifteen years ago. While it still worked, it wasn't very powerful and not much good for anything other than washing the car. I needed something to clean my travertine pool deck, pool waterline, and paver driveway and walks. I also wanted something I knew would be reliable so I wanted a Honda GX engine and CAT pump. This unit checked all of the boxes. Having used it three times so far, I can say I'm not at all disappointed in the performance. It started right up, ran flawlessly, and cleaned everything it needed to quite easily. I did add an inductive hour meter to it before I tarted it up for the first time so I could track the usage for proper maintenance. A few tips...buy a short gun and a long hose. Both will come in handy. It comes with a 25 foot hose so I bought a 50 foot hose (same hose from Simpson) and can connect them for 75 feet of hose. If you have a larger area to clean, you'll appreciate not having to move the machine much. Also, get a surface cleaner. It will cut your work time an a horizontal surface tremendously. I bought a 14" one and I guess a bigger one would have make things a bit faster, but the one I bought was a good compromise between cost and performance. So, why was this going to be a four-star review? Well, the few times I used it, one of the wheels kept falling off as the "E" clip would constantly vibrate off the axel. I kept putting it back on, believing I had it properly seated and it kept falling off. Frustrated, I called the customer service number and they are sending a new "E" clip. While this may solve the problem, I can't really be sure it's not a bad axel that the clip won't properly seat in. So, I emailed Simpson through the "Contact Us" link on the website and within a couple of hours had a response that they are sending me a new axel and clip. Things have issues from time to time but how issues are handled matters. The quick answer to my inquiry and no questions asked (other than my name, address, and unit serial number and purchase date) response was enough for me to be satisfied and provide the five-star review.

Works well but……
Purchased this model due to the Honda engine and the CAT pump. Right out of the box filled the oil and then the gas and with one pull started right up! Exactly what I expected from a Honda engine. Pressure works great , remove the mildew on the house without any issues. Made cleaning the house a breeze. The reason for the 4 stars is that while operating the pressure washer for about 15 minutes I looked back and one of the wheels fell off ! They do not use a cotter pin , instead the use that 3/4 looking washer that fits in a groove on the axel. I don’t think it is a big deal but it is just annoying for something like this to happen.

I bought this pressure washer to replace my old one I've had for years, and give myself a bit more psi for tougher jobs. Assembly out of the box was simple and took no time to put together. Starting unit for first time was not too bad. Throttle needs to be on full for all starts. Instructions say otherwise. And it is a little inconvenient to have to hold trigger on wand in to release pressure to just to start unit once you stop and turn motor off. But it's not bad once you get the hang of it. I cleaned for 3hrs first time out and didn't have any issues whatsoever. I didn't even have to use soap on my trucks the pressure washer is strong enough to remove dirt and other grit no problem. This unit is well worth the money. I'd recommend it to anyone looking to do every kind of pressure washing job and get it done quick and efficiently.

Awesome machine was looking for exact same machine for a while and couldn’t find anywhere awesome

It lasted for about 30 hrs . I believe the pump is not working as no pressure. I comment when I first used it . It was very shakey . Not to surprise it did not last long.

Brand new at the delivery, everything runs well, 25 feet hose is very not enought seriously but a buy a 50 feet . nice machine but you most take care with the first start you better push the guns and crank in the same time !!!!
