Simpson Gas Pressure Washers for 3200 PSI Jobs

Simpson has built a reputation for gas pressure washers that sit between casual homeowner machines and full commercial rigs. If you searched for a Simpson 3200 PSI pressure washer, you will notice that Simpson’s current listings cluster just above that number, from 3300 PSI up to 4400 PSI. PSI (pounds per square inch) tells you how hard the water hits, while GPM (gallons per minute) tells you how much water flows, and together they decide how fast a deck or driveway gets clean.
The six models below differ mainly in engine type, pump design, frame material and included accessories: the Clean Machines target homeowners with maintenance-free pumps, while the PowerShot and Aluminum Series machines add Honda or larger engines and triplex pumps meant for daily professional use.

Simpson PowerShot 3500 PSI Gas Pressure
Best for: Frequent users wanting a Honda engine
Pros
- Honda GX200 with low-oil shutdown
- AAA triplex pump with unloader
- Five nozzle tips included
Cons
- Listing mixes 3300 and 3500 PSI
The Simpson PowerShot 3500 PSI Gas Pressure washer is the model that sits closest to the 3200 PSI mark in this lineup, and there is a reason for that: while the listing title says 3500 PSI, the engine and pump section and the description both describe the pump as delivering 3300 PSI at 2.5 GPM, and the item highlight mentions the code PS3228. The listing does not explain the gap, so it is safest to plan around 3300 PSI as the working figure. The model number is PS61002-S.
The engine is a Honda GX200 with low-oil shutdown, which stops the engine if the oil drops too low so it is not damaged. The pump is a AAA triplex design with an integrated unloader and thermal relief. An unloader redirects water when you let go of the trigger, and thermal relief releases water that gets too hot while the engine idles. You also get a 25-foot MorFlex hose with a threaded M22 connection, a rear-load M22 gun, a 16-inch wand, and five quick-connect tips (0, 15, 25, 40 degrees plus soap). The steel frame rides on 10-inch pneumatic tires, and the listing gives the weight as 74 lb in one place and 72.8 pounds in another.
This suits a buyer who expects to use the machine often, or a small contractor who wants a Honda engine and a triplex pump without stepping up to a larger engine. If you only wash a car and a patio a few times a year, the Clean Machine models below are a gentler fit.

Simpson Clean Machine 3400 PSI Gas
Best for: Driveway and patio owners
Pros
- 15-inch surface cleaner included
- Five-year frame warranty listed
- Maintenance-free axial cam pump
Cons
- No 25-degree tip listed
Best for: Homeowners washing decks and cars
Pros
- Maintenance-free axial cam pump
- Lightest listed weight here
- Two-year engine warranty
Cons
- No 25-degree tip listed
The Simpson Clean Machine 3400 PSI Gas washer (CM61083) is aimed squarely at homeowners. It pairs a 208 cc CRX engine with low-oil shutdown and an OEM Technologies axial cam pump rated at 3400 PSI and 2.5 GPM. Axial cam pumps are the common type on home machines; the listing calls this one maintenance-free and says it has a thermal relief valve. One detail to note: the item highlight mentions an “AAA Axial Cam Pump” while the features name OEM Technologies, so the listing is not fully consistent on the pump maker.
Included gear is a 25-foot MorFlex hose with quick-connect fittings, an ergonomic front-load M22 gun, a 16-inch wand and four quick-connect tips: 0, 15, 40 degrees and soap. The highlight line says five nozzles, but the feature list and description name four, and there is no 25-degree tip in that list. The frame is powder-coated steel on 10-inch pneumatic tires, and the listed weight is 61 pounds (64 lb in the features), which makes it the lightest machine here. The warranty is listed as two years on the engine and one year each on pump and frame.
Choose this one if you want to clean decks, siding, fences, patio furniture and cars on weekends and value simple upkeep. Pros who run a machine for hours every day should look at the triplex-pump models instead.
Simpson Clean Machine 3400 PSI Gas with Surface Cleaner for Driveways
The Simpson Clean Machine 3400 PSI Gas kit (CM61248-S) uses the same core recipe as the model above: a 208 cc CRX engine with low-oil shutdown and a maintenance-free OEM Technologies axial cam pump at 3400 PSI and 2.5 GPM with a thermal relief valve. The difference is in the box. It adds a 15-inch surface cleaner, a round attachment with two rotating stainless steel nozzles under a powder-coated steel shroud. The listing says it provides 10 times more coverage than a standard spray nozzle, and the shroud helps keep overspray off walls and cars.
You also get a 25-foot non-marring 5/16-inch hose, an ergonomic M22 gun, a 16-inch wand and four quick-connect tips (0, 15, 40 degrees and soap). The listed warranty is five years on the frame, one year on the pump and two years on the engine. The weight is 64 pounds.
If most of your cleaning is flat concrete such as a driveway, sidewalk or patio, this bundle is the easiest route. A surface cleaner avoids the stripes that a single nozzle often leaves, which matters a lot for a first-time owner still learning how to hold the wand steady.

Simpson Cleaning 3400 PSI Gas Pressure
Best for: Contractors wanting a lighter frame
Pros
- CAT triplex plunger pump
- Aircraft-grade aluminum frame
- Five-year pump warranty listed
Cons
- Components line lists 3200 PSI, 2.8 GPM
The Simpson Cleaning 3400 PSI Gas Pressure washer (ALH3228-S) belongs to the Aluminum Series. It uses a Honda GX200 commercial series engine and a CAT Industrial triplex plunger pump rated at 3400 PSI and 2.5 GPM with thermal relief protection. The frame is aircraft-grade aluminum with brushed extruded tubing, which resists corrosion. The listing’s included components line reads “Aluminum 3200PSI, 2.8GPM”, which does not match the 3400 PSI and 2.5 GPM stated everywhere else, so treat that line with caution.
Accessories include a Monster 5/16-inch by 25-foot hose, five quick-connect tips (0, 15, 25, 40 degrees and soap), a 16-inch steel wand and a professional gun with a safety lock-out. The pump connection is listed as QC. The weight is 73 pounds, and the warranty is listed as three years limited commercial on the engine, five years on the pump and one year on the frame.
This model suits contractors in deck cleaning and wood restoration who want a CAT pump and a frame that will not rust. Homeowners will get similar pressure from the Clean Machines with less weight to lift into a car.
Simpson PowerShot 4400 PSI Gas Pressure for Big Jobs
Best for: Pros cleaning large areas fast
Pros
- 0 GPM for faster rinsing
- 50-foot 3/8-inch hose
- 13-inch tires
Cons
- Heaviest model here
- Description quotes different figures
The Simpson PowerShot 4400 PSI Gas Pressure washer (PS60843) is the largest machine in this group. It runs a CRX 420cc engine and a maintenance-free AAA industrial triplex plunger pump rated at 4400 PSI and 4.0 GPM, with thermal relief and PowerBoost Technology for higher pressure at the nozzle. The description, however, talks about 4000 PSI at 3.5 GPM and a model called PS60869, so the listing mixes two versions; the title, features and model number all point to 4400 PSI and 4.0 GPM.
It comes with a Monster 3/8-inch by 50-foot hose with a polyurethane jacket, five quick-connect tips, an ergonomic gun and a 31-inch wand. The welded steel frame rolls on 13-inch pneumatic tires, and the listed weight of 61.23 kg (about 135 pounds) makes it far heavier than anything else here. The listing adds that machines are factory tested and may arrive with a little residual fuel or oil odor.
The higher GPM is what makes big areas go faster, since more water carries dirt away sooner. Pick this if you clean large lots, fleets or long fences for work. For typical home decks, it is more machine than most people need.
Simpson Aluminum Series 3600 PSI Gas for Long-Term Pro Use
Best for: Pros wanting long warranty coverage
Pros
- Longest listed warranty terms
- 35-foot MorFlex hose
- PowerBoost at the nozzle
Cons
- Heavier than the Clean Machines
The Simpson Aluminum Series 3600 PSI Gas washer (ALH3425) combines a Honda GX200 engine with low-oil shutdown and a AAA triplex plunger pump rated at 3600 PSI and 2.5 GPM. The pump has an integrated unloader, thermal relief and PowerBoost Technology. The features describe an aircraft-grade aluminum frame, though the item highlight line says “Steel Frame”, so that line appears to be a copying error in the listing.
The hose is a 35-foot MorFlex non-marring hose with a threaded M22 connection, the longest among the 2.5 GPM machines here. You also get five quick-connect tips, a professional QC gun with safety lock-out and a 16-inch wand. It rides on 10-inch pneumatic tires and weighs 78 lb. The warranty is listed as three years on the engine, five on the pump and ten on the frame, the longest terms in this roundup.
This fits a professional who wants extra hose reach and long coverage. Buyers who only need a machine a few weekends a year will not use what they are paying for in build and warranty. You can read more about the wider range in our Simpson gas pressure washer guide.
How to Choose the Right Simpson Gas Pressure Washer
Start with how often you will use it. For a few weekends a year, the Clean Machine 3400 PSI models with their maintenance-free axial cam pumps keep things simple. For weekly or daily work, the triplex-pump machines (both PowerShots and both Aluminum Series units) are built for longer run times.
Next, think about the surfaces. Soft wood decks usually call for wider tips such as 25 or 40 degrees, and only the PowerShot and Aluminum Series machines list a 25-degree tip. If your main job is concrete, the Clean Machine with the 15-inch surface cleaner saves time and avoids stripes.
Consider weight and storage. The Clean Machines are listed at about 61 to 64 pounds, the Honda-powered models at 72.8 to 78 pounds, and the PowerShot 4400 is much heavier. If you have steps or need to lift the unit into a vehicle, that gap matters. If gas engines feel like too much for your space, a lighter battery power washer may be a gentler starting point for light tasks.
Finally, check the location rule: every listing here says 49-State Compliant and not for sale in California.
FAQ
Does Simpson make an exact 3200 PSI gas pressure washer in this lineup?
None of these six listings is rated at exactly 3200 PSI. The PowerShot 3500 is described as 3300 PSI in its features, which is the closest, and the Aluminum Series ALH3228-S mentions 3200 PSI only in a components line that conflicts with the rest of its listing.
Which Simpson pressure washer has the Honda GX200 engine?
Three models list it: the PowerShot 3500 PSI (PS61002-S), the Aluminum Series 3400 PSI (ALH3228-S) and the Aluminum Series 3600 PSI (ALH3425).
What is the difference between an axial cam pump and a triplex pump?
Axial cam pumps are compact and common on homeowner machines, and Simpson lists the Clean Machine versions as maintenance-free. Triplex plunger pumps are generally designed for longer daily run times and are the type used on the professional models here.
Which Simpson pressure washer should a first-time buyer get?
For most homes, one of the Clean Machine 3400 PSI models is the easiest start. Choose the surface cleaner kit if your driveway or patio is the main job.
Can I buy these in California?
No. Every listing states the machines are 49-State Compliant and not for sale in California.
