Pressure, Hose, and Build Comparison
Maximum Pressure
The Simpson PowerShot 3300 PSI Gas Pressure Washer delivers 3300 PSI of cleaning power. The Simpson Aluminum Series 3600 PSI Gas Pressure Washer offers a higher output of 3600 PSI. This 300 PSI difference means the Aluminum Series can tackle tougher grime on decks or concrete more effectively. Both machines maintain a steady 2.5 GPM flow rate, so the extra pressure is the primary performance gap. You get more force with the Aluminum Series model for heavy-duty jobs.
Hose Length
Reach matters when cleaning large areas like driveways or siding. The Simpson PowerShot comes with a 25-foot Morflex high-pressure hose. The Simpson Aluminum Series includes a longer 35-foot Morflex hose. That extra 10 feet reduces the need to move the unit around as often. Both hoses feature non-marring polyurethane jackets to protect finished surfaces and resist kinks. The threaded M22 connection is standard on both, ensuring compatibility with your existing accessories.
Frame Material
Build quality affects longevity and portability. The PowerShot uses a welded steel frame with a powder-coated finish for corrosion resistance. The Aluminum Series features an aircraft-grade aluminum frame, also powder-coated for durability. Aluminum is naturally lighter and more resistant to rust than steel, which is beneficial if you store the unit outdoors or in damp conditions. Both frames are designed for easy assembly and provide a balanced layout for transport.
Flow Rate
Flow rate determines how quickly water covers a surface. Both the Simpson PowerShot 3300 PSI and the Simpson Aluminum Series 3600 PSI deliver 2.5 GPM. This identical flow rate means cleaning speed remains consistent between the two models when pressure is equalized. The pump type is also the same, utilizing a maintenance-free AAA triplex plunger design. You get the same water volume regardless of which unit you choose for general washing tasks.
Nozzle Count
Versatility depends on the included accessories. Both pressure washers come with five quick-connect tips: 0°, 15°, 25°, 40°, and a soap nozzle. This set covers tasks from stripping paint to gentle car cleaning. The PowerShot includes a rear-load M22 gun and a 16-inch spray wand. The Aluminum Series adds a professional QC spray gun with a safety lock-out feature. While the gun differs, the nozzle count and variety remain identical for both units.
Which Pressure Washer Fits Your Needs
Heavy-duty deck and fence cleaners
The 35-foot hose provides significantly more reach than the 25-foot option on the PowerShot. This extra length reduces the need to move the unit frequently when cleaning large surfaces like decks or long fence lines. The PowerBoost Technology also delivers higher pressure at the nozzle, making it easier to strip paint or remove stubborn grime from tough materials without excessive scrubbing.
Users prioritizing lighter weight and portability
At 74.8 pounds, this model is lighter than the Aluminum Series version, which weighs 79 pounds. The welded steel frame offers durability while keeping the overall mass lower. If you frequently transport your pressure washer to different job sites or need to lift it into a truck bed, the reduced weight makes maneuvering and loading noticeably easier and less strenuous.
Those needing maximum cleaning power
With 3600 PSI compared to the 3300 PSI output of the other model, this unit offers higher pressure for demanding tasks. The combination of increased pressure and PowerBoost Technology ensures stronger cleaning performance at the nozzle. This extra power is beneficial for contractors who need to clean equipment, remove graffiti, or handle heavy-duty surface prep quickly and effectively.
