This Simpson 4400 PSI, 4.0 GPM gas washer stands out for raw cleaning power and a price far below comparable Honda powered models. The triplex pump and commercial frame are framed as a major step up from axial cam units, and the flow rate should cut cleaning time on decks, driveways, and siding. The main cautions are pump reliability and Simpson support, with reports of no pressure out of the box, overheating if run dry, and slow warranty or return handling. It looks like a strong value if you are prepared to maintain it carefully.
Common Questions (6)
At $499.99, it is a strong value if you want 4400 PSI and 4.0 GPM for non-commercial use, especially versus higher retail prices like $887.50 at Home Depot or $1,399 for a Honda-engine Simpson. The tradeoff is that some shoppers prefer spending more for a Honda engine and CAT pump for longer-term reliability.
Do not start it without water flowing, and do not let it run without spraying for more than 1-2 minutes because that can overheat the pump. Using ethanol-free fuel and running the carb dry after each use are also recommended to help the engine and fuel system last longer.
The AAA triplex pump on this model has been reported to have pump problems, and some buyers also describe broader Simpson quality issues. A few units have arrived with no pressure out of the box, while others have worked normally, so it is worth checking the pump immediately on arrival.
Yes, the AAA triplex pump is a major step up from an axial cam pump and is generally treated as the more durable design. Long-term examples in the thread include triplex-pump units lasting 5-6 years and even about 13 years with regular oil changes.
Woot did allow a return for a defective unit, but the process took nearly a week of email back-and-forth before pickup. The buyer was ultimately fully refunded.
The warranty covers repairs, but the washer may be out of service for weeks while it is being fixed. That makes downtime the main drawback if the unit fails during the warranty period.
