How each alternative compares
Simpson 3600 PSI Gas Pressure Washer
This Simpson model shares the same 3600 PSI and 2.5 GPM output as the original, but it swaps the lightweight aluminum frame for a heavier steel cart. The dimensions are slightly wider and taller, adding stability for commercial job sites. It keeps the robust pump quality but loses the easy assembly and corrosion resistance of the aluminum series. You should pick this if you need a stationary, heavy-duty solution for frequent professional use rather than a portable unit for home contractors.
Westinghouse 3200 PSI Gas Pressure Washer
The Westinghouse WPX3200 drops pressure to 3200 PSI while maintaining the 2.5 GPM flow rate. It uses a steel frame instead of aluminum, making it lighter at 63 pounds.

It is a practical choice for users who prioritize durability and value over maximum pressure specs. Choose this if you clean smaller areas and want a more budget-friendly option with useful accessories included.
