Simpson may not be the first name that pops into your head when you think of pressure washers. However, they are a leader. Indeed, it’s among the largest vertically integrated gas-powered pressure washer manufactures in the U.S. What’s more, we’re well familiar with their fleet. Recently, our reviewers got their hands on the 3500 PSI Simpson Pro Pressure Washer (PS61374).
Here’s what they thought about whether this model can serve both residential and Pro users.
Simpson Pro 3500 PSI Pressure Washer Performance
- Max PSI: 3500
- Flow Rate: 2.5 GPM
- Nozzles: 0°, 15°, 25°, 40°, and soap nozzles
Cleaning Power
As its name suggests, the PS61374 has an engine and a AAA triplex pump that can produce 3,500 PSI. Moreover, its peak flow is 2.5 GPM. We like those numbers as a solid middle-ground for an entry-level gas unit.
And, based on these performance specs, there’s no shortage of projects that it can tackle. For example, you can hit concrete, PVC fences, decking, siding, windows, and vehicles, among others. Perhaps the biggest difference between the Simpson Pro 3500 PSI pressure washer and a model like the brand’s 4,000 PSI PS61371 is cleaning speed. That’s a matter of PSI vs GPM .

Profile
In terms of construction, Simpson’s designers went with a powder-coated steel tube frame. Our reviewers gave that choice a thumbs up for its corrosion resistance. This is pretty important when your gear uses water and, if desired, cleaning additives.
Of course, the Simpson Pro 3,500 PSI pressure washer isn’t without its drawbacks. For instance, some found the handle height to be a bit low, at 25 inches. Yet, you do need to take into account that this is a compact model, which has its obvious storage benefits.
Meanwhile, the frame is 21 inches wide, which makes for open engine access. Important parts like the oil reservoir were easy to reach. Additionally, our reviewers liked where Simpson’s designers positioned the hose and accessory management systems.
Pump
The PS61374’s AAA triplex pump is heavy duty and, in our opinions, can handle commercial usage. These pumps undergo CETA CPC-100 certification testing for pressure and flow, so they’re confident in this position.
Simpson Pro Pressure Washer CRX Engine
Likewise, the CRX engine on the PS61374 is tough enough to handle heavy-duty usage.
Simpson designed this power plant for professional and residential applications. It has the key features that both populations need, including easy starting, reliable performance, and a low oil shutdown. To put all of this into context, based on the brand’s confidence in this engine, they offer a 5-year warranty, which is two years longer than Honda’s.
Simpson Pro 3500 PSI Pressure Washer Price
The Simpson PS61374 retails for $579 and comes with a 25-foot 5/16-inch MorFlex hose as well as 0°, 15°, 25°, 40°, and soap nozzles.
