Buyer’s Guide: What to Consider

Choosing the right gas pressure washer depends on your cleaning needs. Focus on PSI, GPM, engine type, and mobility features to find the best match.

• Pressure (PSI): PSI measures cleaning power. For home use, 3000-3400 PSI is sufficient. Commercial tasks may need 4000+ PSI.
• Flow Rate (GPM): GPM indicates water volume. Higher GPM cleans faster. 2.5 GPM is good for home; 4 GPM is for heavy-duty work.
• Engine Type: Gas engines offer portability and high power. Look for OHV engines with low-oil shutdown for durability and safety.
• Hose and Mobility: A longer, kink-resistant hose (25ft) and large wheels (10-12 inches) improve reach and maneuverability on rough terrain.
• Pump Quality: Axial cam pumps are common and maintenance-free. Thermal relief valves protect the pump from overheating during use.

Conclusion

Each of these five gas powered pressure washers excels in different areas. The Simpson Clean Machine is great for homeowners, while the IvyBess handles commercial jobs. Westinghouse offers versatile electric and gas options.

For most people, the Westinghouse WPX3400 provides an excellent balance of power and flow for large home projects. Consider your typical tasks and choose the model that fits your needs best.
