Aluminum Series

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 :)

Arrived perfectly sealed and undamaged, no dings as some have mentioned. The pressure washer does what it should. It can be a bit difficult to start if pressure builds in the hose with each pull. Just squeeze trigger and release pressure, simple enough to fix and not really a “fault” as pressure is what it does. It is just something to note. The hose, sucks. It constantly wants to coil. It works yes, but you will fight it. Invest in a better hose. No complaints about the machine itself. Ran well, maintained pressure, no sputters or stops. Tires roll well as they are large relative to the machine. Overall pleased, just replace the hose.

I haven’t used mine yet but have used the product before and the reason I purchased it.

Researched a new pressure washer for weeks. I looked at all sorts of online suppliers and Amazon had exactly the model with the engine I was looking at that matched my requirements. Delivery was fast, the pressure washer was in perfect condition and once I got the oil into the engine and gassed it up, the engine started on the first pull. The engine is shipped without oil but oil is included. The hydraulic pump has oil in it but be SURE to remove the small black plug from the center of the red hydraulic pump cover or you can damage the pump. I did have one issue on arrival that has been reported by other Amazon customers. See the photo of the wheel with the arrow pointing at the retainer clip. That clip came off almost instantly. I removed the axle and both wheels and used a triangular file to cut the notch in the axle a bit deeper on both sides to hold the retainer clip. Sloppy manufacturing on the part of Simpson. I’ve used a very similar but smaller version of this Simpson pressure washer for decades. Honda engine is the only way to go and the Cat pump has seal rebuild kits. The 5 pressure tips included cover most situations and pay attention to using the right tip for the right job. The 3400 psi model is ideal for most homeowner purposes including siding, concrete, and patio cleanup. NEVER point the water stream at skin, other people or animals. A 3400 psi water jet up close can cause severe tissue and damage skin in an instant. Wear work shoes with safety toes and eye protection. As a long time owner of machine exactly like this one there are a few things owners need to do to ensure quick starts and trouble free service. I read many low star reviews focused on hard starting. It’s not the machine, it’s the owner and their failure to follow some simple maintenance rules. This is key - ALWAYS run the fuel out of the carb when you’re done even if the machine will only sit for a few days. Use ethanol free gas with fuel stabilizer. Failure to use stabilizer and run the carb dry will cause 90% of hard starting problems. Change the engine oil and the hydraulic pump oil more often than required and use the proper oils. Check the air filter and the fluids regularly. I really like Simpson machines with Honda engines. I’ve had tremendous longevity and cleaning outcomes from these machines, and I highly recommend them. I deducted 1 star for 3 reasons. The first reason is the axle issue mentioned above where the retainer clip pops off that I fixed. Second is that the handle is too short if you are 6 feet or taller like me - it's an ankle biter when I pull it around. Finally, it needs flat free wheels, pneumatic wheels are annoying. That's it - great machine with some shortcomings. Hope this helps!

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.

When it is working, it’s so powerful and smooth. Design and built seems and feels high end and durable, however, it is VERY HARD to start. If the first full doesn’t start, no chance to start at second attempt. I owned gas pressure washer for almost 30 years, none of previous ones does that. It is way more pickier than my previous Excel. The Excel lasts 15 years for me. First, it is picky about fresh gas, it refused to start while brand new maybe just because the gas was two months old, now again, it won't start because the gas was almost two months again. My previous Excel can use gas more than 6 months old, Simpson engine is a princess--high maintenance picky machine. Second, the pressure built up so fast, if the first attempt wasn't successful, no way to start at the second. Even my neighbor who got a cheaper model of Simpson said this one is TIGHT. I'm so SCARED of starting it every time, needs a lot of pulls and luck. Excel only needs about 1-2 seconds of release pressure , this Simpson really needs 30 seconds to try my second luck. To start the machine is a TWO man job, one has to release the trigger on the other end constantly!! Third, even if I'm lucky to start it, it coughs/farts often and I have to be very careful to move the engine from choke to normal SLOWLY, otherwise it stops. Fourth, it gives farts loud several times when switched to off position. None of my previous ones did that, not once. Now I have to get used to the random noise after spending $800! Ordered one electric pressure washer last night, I'm done with the gas one especially with NO HELP from the seller...weird from day 1 Tech support is NOT responsive at all! My question never received answer.

Honda GX200 engine with a Cat pump. Starts on every pull. The first cleaning was a Ford F-250. The second cleaning was a screened room at lake Sam Ray urn. Excellent job.

Great product with great parts. Honda engine, CAT pump on an aluminum frame.... great little setup!

Works well, nice and light. great if you want to throw it in the back of your truck

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

A rubber foot came off right away. Either the screw is too small or the whole for the screw is too large? Screws in hand tight but tears out easily. Love everything else about this unit.

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.
