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 :)

Machine good, hose not so good
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.

Powerful BUT it is VERY HARD to START, NO customer service al all
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.

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.

Packaged, crated and shipped extremely well - no problems and no damage. Started up right away - 4 pulls after assembling out of the box. It ran for several hours straight and didn't stall once. It felt more powerful than others that claim 3400 psi, but that's hard to quantify. The frame is made well, there's adequate clearance on the underside, the handle is a good length away from the engine that it balances well when moving,, and the wheels are a good size with good treads. Both the printed instructions and the labels attached to the engine and sprayer were complete, comprehensive, and very well done (I appreciate instructions in proper English with good diagrams!) It even looks impressive with the red Honda engine, black trim, grey hose, and aluminum frame. I just hope the Honda engine lives up to its reputation for longevity. The only "complaints" (and they are minor) are the spare spray nozzles can't be snapped on to the frame (they just rest in holes), the hose is stiff and challenging to unwind when coming out of the box, it is difficult to coil the hose and hang it from the frame after use (hanger doesn't hold all the hose), the handle kicks a fair bit when the trigger is depressed (because of the power), and my neighbours like it so much they've already asked to borrow it several times!

I use pressure washers for a variety of cleaning and stripping chores. I had acquired an extended pole that reaches to the peak of a second story house. My old pressure washer didn't have the power to run it...this one does effortlessly (I also have a gutter wand and can now clean the gutters without going near a ladder). Not an indictment against this model or brand, but against all pressure washers in general. I wish someone would come up with an accessory bracket or some way to support the garden hose so it does not stress the connection (I know. Shut the machine off and grab the hose and move it, but I have large areas I do and like to keep going)
