We’ve used a lot of the best pressure washers over the years and we consistently keep turning back to Simpson because we get better quality and performance than other models at the same price. Still, there are a lot of Simpson pressure washer options, so we decided to help you narrow down the lineup with our favorites.
Choosing the Right Level
Simpson pressure washers are specifically designed to meet the needs of several different levels. Choose the right one for your needs to make sure you get the best possible experience within your budget.
- Residential: Clean Machine
- Premium Residential: MegaShot
- Commercial: Pro Series, PowerShot, Aluminum, and Water Blaster
- Industrial: Industrial, Water Shotgun, Super Pro, and Rental
There are other specialty categories as well as replacement pumps, hoses, and accessories. Since we’re guessing you landed here for traditional pressure washers, we’re going to focus on the first three categories.
Comparing Pressure Washer Cleaning Power
When you’re comparing pressure washer ratings for pressure and flow rate, an easy way to see how they match up is to multiply the PSI and GPM. This gives you a general “cleaning power” rating, and the higher, the better. Here’s an example:
While it might seem like the 3600 PSI model is the best choice, the 3200 PSI model actually has mode cleaning power and can help you get the job done more efficiently.
Alright, let’s get on with the recommendations already!
Best Simpson Electric Pressure Washer
Clean Machine 2300 PSI Electric Pressure Washer
Without a doubt, our favorite electric Simpson pressure washer is the Clean Machine CM60976. With a max pressure of 2300 PSI and water flow topping out at 1.2 GPM, there are very few options that can give you more cleaning power without turning to a gas engine. This one gets a brushless motor upgrade. Even though that’s something we typically see on cordless power tools, the pressure washer gets the benefits of lower maintenance and longer life compared to brushed motors.
Best Simpson 3000 PSI Pressure Washer (2800 – 3000 PSI)
Residential: Simpson Clean Machine 2800 PSI Pressure Washer
At $299, Simpson’s Clean Machine CM61081 is an excellent entry into gas-powered pressure washers and it doesn’t cost an arm and a leg compared to electric options. With 2800 PSI and 2.3 GPM max ratings, you’ll see significantly faster cleaning than a corded unit.
One minor downside is that it only has space for the three nozzles that come with it: 0º, 25º, and soap. If you want to add the 15º, 40º, and/or turbo nozzles that come with some pressure washers, you’ll have to add those separately.
Premium Residential: Simpson MegaShot 3000 PSI Pressure Washer with 15-Inch Surface Scrubber
If you’re willing to come up in price about $100 into the premium residential class, you get a couple of excellent benefits with the Simpson MegaShot MS60805-S. For starters, you get more cleaning power with pressure up to 3000 PSI and volume up to 2.4 GPM.
This unit comes with a Honda GCV160 engine known for its reliability. Simpson also includes their 15-inch surface scrubber to go with it. Surface scrubbers can save you hours of work just on your driveway and it’s our #1 recommended add-on, so the fact that this MegaShot pressure comes with one is a huge bonus in our opinion.
Best Simpson 3200 PSI Pressure Washer (3100 – 3300 PSI)
Residential: Simpson Clean Machine 3300 PSI Pressure Washer
If your cleaning needs are higher than entry-level gas can take you, check out Simpson’s Clean Machine CM61117 for an excellent balance of performance and value. Simpson turns to a Kohler SH265 engine paired with their OEM Technologies axial cam pump to deliver as much as 3300 PSI and 2.4 GPM.
Unlike the previous Clean Machine we recommended, this one comes with a full suite of nozzles: 0°, 15º, 25°, 40°, and soap. This one also shifts from thinner no-flat wheels to 10-inch pneumatic that make it easier to pull the pressure washer across your lawn.
Premium Residential: Simpson MegaShot 3300 PSI Pressure Washer with 15-Inch Surface Cleaner
Are you sensing a theme with our recommendations yet? When it’s in your budget, we really like the benefits of a Honda engine and we highly recommend a surface scrubber. Moving into this power level, Simpson’s MS61033-S goes with a Honda GCV190 engine that offers 3300 PSI and 2.4 GPM through its OEM Technologies axial cam pump.
Commercial: Simpson PowerShot 3300 PSI Pressure Washer
Commercial-level pressure washers come into play with Simpson’s PowerShot PS3228. It uses a commercial-grade Honda GX200 engine and shifts from axial cam to a AAA triplex pump. The combination sets you up with a machine designed for much more frequent use over long hours. This entry-level commercial model boasts 3300 PSI with 2.5 GPM using a 5/16-inch hose.
Best Simpson 3500 PSI Pressure Washer (3400 – 3700 PSI)
Residential: Simpson Clean Machine 3500 PSI Pressure Washer with 15-Inch Surface Scrubber
Moving up in power to another level, Simpson’s Clean Machine CM61118 shares the same Kohler SH265 engine as our previous recommendation. This time it pairs with a AAA AX300 axial cam pump dialed into 3500 PSI and 2.5 GPM.
In addition to its higher performance level, Simpson includes their 15-inch surface scrubber with the kit along with their standard 5-piece nozzle set and steps up to a 5/16-inch hose.
Premium Residential: Simpson MegaShot 3400 PSI Pressure Washer
Wrapping up the top performance for the premium residential line, the MegaShot MS61084-S (61085 if you’re shopping online) switches back over to Kohler for its powerplant, using their SH265 engine with an OEM Technologies axial cam pump to get 3400 PSI and 2.5 GPM.
Note that this model also steps up from a 1/4-inch hose to a 5/16-inch. This is also priced less than our previous MegaShot recommendation, but it doesn’t include a surface scrubber.
Commercial: Simpson Pro Series 3700 PSI Pressure Washer
Lifting the pressure higher, the Simpson Pro Series PS60982 carries a Honda GX200 engine and gets an extra bump in performance from its AAA triplex pump with PowerBoost. Hitting 3700 PSI and 2. 5 GPM, this commercial-level pressure washer comes with a 50-foot 5/16-inch hose to extend your reach beyond what standard 25-foot hoses offer. If you’re looking for the best power you can get without a significant increase in overall size, this is where it’s at.
Best Simpson 4000 PSI Pressure Washer (3800 – 4200 PSI)
When you start looking at the 4000 PSI level, you’re getting away from residential models and into pressure washers where you should expect a commercial build. Simpson has several great options to choose from and we like the PowerShot PS4240 edging out the aluminum-framed ALH4240.
Generating 4200 PSI and 4.0 GPM, this is about as much cleaning power as you can hope without jumping into Simpson’s belt-driven models. To get that kind of power, Simpson uses a Honda GX390 engine and pairs it with a AAA triplex pump with PowerBoost. At this level, it also uses a 3/8-inch hose that’s 50 feet long.
