Main trade-off
Simpson PowerShot 3300 PSI Gas Pressure Washer
At roughly 77 pounds with a gas engine, it is louder, heavier and more maintenance-intensive than any corded electric here.
Head-to-head
Choose the Simpson for its Honda engine and serviceable triplex pump when repeated use justifies the premium. Choose the Westinghouse for strong independently measured output at a simpler residential ownership tier.

Main trade-off
At roughly 77 pounds with a gas engine, it is louder, heavier and more maintenance-intensive than any corded electric here.
Main trade-off
Car and Driver measured about 95 dBA, and its 3000-PSI-class tested output is unnecessarily aggressive for routine car paint.


Compare two high-flow gas pressure washers by pump type, engine, measured output, mobility and ownership cost.
The practical choice turns on pump and rating, then on the constraints in your own setup.
Winner by situation
For pump, Simpson PowerShot 3300 PSI Gas Pressure Washer records “AAA triplex plunger” and Westinghouse 3200 PSI Gas Pressure Washer records “Maintenance-free axial cam”. This describes the working hardware or mechanism. The label alone does not prove faster or better results.
Its rated or tested operating pressure is suited to stubborn hard-surface grime. Nozzle distance still controls surface risk.
For rating, Simpson PowerShot 3300 PSI Gas Pressure Washer records “3300 PSI / 2.5 GPM” and Westinghouse 3200 PSI Gas Pressure Washer records “3200 PSI / 2.5 GPM”. Check whether the two records use the same definition and test conditions before treating the difference as decisive.
For availability, Simpson PowerShot 3300 PSI Gas Pressure Washer records “Not California compliant” and Westinghouse 3200 PSI Gas Pressure Washer records “Check current state listing”. Confirm the exact model and included package because this row describes the selected offer, not every version sold under the family name.
