Style: 4200 PSI Honda GX390
Phenomenal so far. I was going to spend around $500/$600 but after research I determined the Honda engine, 4GPM flow, and CAT pump were critical. Ended up spending slightly more than double my original budget, but so glad I did. Combined with a surface cleaner, I cleaned the entire pool deck in 30-45 minutes which would have taken me 5 hours before and not as good results.

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 :)

Purchased this machine because it had the Honda GX engine & because it was made in the USA! Have several other Honda powered pieces of equipment that have been reliable, easy start and trouble free. However, this SIMPSON power washer would not start I should say, after about 5 tries it did start several times but then immediately died Took me repeated tries (nearly an hour) with waiting, in case it was flooded, between tries. Once I did finally get it started I could not adjust the choke or throttle, as suggested in the manual, without the machine dying . The machine only ran for a few minutes before it began backfiring. It would only run without backfiring if the water wand was kept in the washing position at all times. I could not take my hand off the wand handle or the machine would backfire. After calling the help line their only suggestion was for me to take this brand new machine into the repair shop. It was Saturday, mid day by this time, and the repair shop did not have a repair person available to help so would have to leave it for them to look at in a few days or so. Out of frustration I tried to go ahead and continue using it and kept the power wand in the open-wash position but gradually the machine started backfiring anyway. I turned it off and let it rest thinking maybe it was hot (my previous power washer - 15 years old - would run and run until out of gas, then I would let it rest and cool before re-filling the gas tank.) After turning it off, I was not able to restart it again. I had hired a couple young men to come help me move items, power wash under & behind, then return the items to their proper place. Many of the things had already been moved. I Needed to get power washing under and behind before returning them to their place. I had already been paying for them to stand around while trying to get the machine started then trouble shoot on the phone. I had to go buy a Costco power washer so I could get the work done while I had helpers!!! Now the company whom sent this is saying it can not be shipped after oil & gas have been added. It had oil in the pump when it was shipped so this does not ring true. Besides I can completely empty the gas and let any residual evaporate and the oil can be drained. I do not need 2 power washers and certainly not one that doesn't work! Needless to say I am not a happy camper right now! I purchased this through AMAZON so hopefully their guarantee will help me with this problem. P.S. This machine is now on line for $100.00 less than my purchase price :(
