Honda engine is awesome and started on the first pull. Plenty of power to pressure wash deeply for driveways, etc. ### ⭐⭐⭐⭐⭐ Simpson 3600 psi power washer *by L***D on March 27, 2026* Works as expected. Very powerful and engine started on first pull. ### ⭐ would not run :( *by V***. on August 21, 2019* 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 :( ## Frequently Bought Together - Simpson Cleaning 3600 PSI Gas Pressure Washer, 2.5 GPM Power Washer for Commercial Use, Honda GX200 Engine, 35-Foot MorFlex Hose, Aluminum Series, 49-State (ALH3425) - Simpson Cleaning 80143 3600 PSI Universal Turbo Pressure Washer Nozzle, 1/4-Inch Quick Connect, Hot- or Cold-Water Use, Black - Simpson Cleaning 40226 Morflex Series 3700 PSI Pressure Washer Hose, Cold Water Use, 5/16 Inch Inner Diameter, 50 Feet, Natural --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/34952121-simpson-3600-psi-gas-pressure-washer-2-5-gpm-commercial](https://www.desertcart.vn/products/34952121-simpson-3600-psi-gas-pressure-washer-2-5-gpm-commercial) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-25*
