Main trade-off
Greenworks 3000 PSI Brushless Electric Pressure Washer
Its headline 3000 PSI and 2.0 GPM are separate operating points: Greenworks specifies 1.1 GPM at 3000 PSI and 2.0 GPM at 100 PSI.
Head-to-head
The Greenworks is the right default for most homes because it starts instantly, stores without fuel and handles routine cars, decks and patios. The Simpson earns its upkeep only when repeated large concrete jobs need 2.5 GPM and a triplex pump.
Before you choose
Greenworks 3000 PSI Brushless Electric Pressure Washer has the stronger fit for “I want plug-in simplicity” and “I want minimal upkeep”. Simpson PowerShot 3300 PSI Gas Pressure Washer has the stronger fit for “I need sustained heavy-duty cleaning” and “Fast rinsing matters most”.

Main trade-off
At roughly 77 pounds with a gas engine, it is louder, heavier and more maintenance-intensive than any corded electric here.


A concrete decision between a leading residential electric and a triplex-pump gas model, based on job time, upkeep, noise and output.
The practical choice turns on best use and power, then on the constraints in your own setup.
Winner by situation
For hose and movement, Greenworks 3000 PSI Brushless Electric Pressure Washer records “25-foot hose and 10-inch wheels” and Simpson PowerShot 3300 PSI Gas Pressure Washer records “25-foot hose and pneumatic tires”. This affects working reach and where the main unit or power source must stay during use.
For power, Greenworks 3000 PSI Brushless Electric Pressure Washer records “Corded electric” and Simpson PowerShot 3300 PSI Gas Pressure Washer records “Honda GX200 gas engine”. For power, the published output matters only when the room, surface or workload needs the extra headroom. It does not prove better results by itself.
For pump and service, Greenworks 3000 PSI Brushless Electric Pressure Washer records “Brushless electric platform” and Simpson PowerShot 3300 PSI Gas Pressure Washer records “Serviceable AAA triplex pump”. This changes long-term ownership risk rather than day-one performance.
Its triplex pump is intended for longer service and repairability than a typical sealed residential axial-cam pump.
For high-pressure output, Greenworks 3000 PSI Brushless Electric Pressure Washer records “3000 PSI at 1.1 GPM” and Simpson PowerShot 3300 PSI Gas Pressure Washer records “3300 PSI at 2.5 GPM rating”. For high-pressure output, the published output matters only when the room, surface or workload needs the extra headroom. It does not prove better results by itself.
It combines useful flow with adjustable spray patterns, which matters more than chasing maximum PSI on wood, vinyl and painted surfaces.

What you give up
What matters in practice
Start with the Greenworks if your jobs are occasional and within reach of an outlet. Pay for the Simpson only when repeated broad concrete work makes its extra flow worth the engine upkeep.
The Greenworks starts with a trigger pull, needs no fuel and stores without an engine routine. Its output covers vehicles, decks and normal patio cleaning when the cord and hose can reach.
The Simpson is rated at 2.5 GPM, more than twice the Greenworks flow at its 3000 PSI point. That difference matters during repeated surface-cleaner passes across a large driveway. It matters far less on one car or a small deck.
Greenworks lists 3000 PSI at 1.1 GPM and a separate 2.0 GPM maximum at 100 PSI. Those numbers describe different operating conditions and should not be multiplied together as if they happen at once.
The Simpson weighs about 77 pounds and brings engine noise, fuel, oil and seasonal storage. Its pneumatic tires and triplex pump suit repeated work, but they solve problems an occasional user may never have.
What the facts say
Useful conclusions from the current pressure washers comparison, followed by the checked facts used to reach them.
None of the 28 models checked covers every part of “I want plug-in simplicity”, “I need sustained heavy-duty cleaning”, “I want minimal upkeep”, and “I have a large area to cover”, so the recommendation favors the closest practical compromise.
