What Makes a Great Home Exterior Pressure Washer?
Key Performance Factors
PSI (Pounds per Square Inch): This measures the water pressure force. For home exterior cleaning:
- 1300-1900 PSI: Light-duty (cars, patio furniture)
- 2000-2800 PSI: Medium-duty (siding, driveways, decks)
- 2900+ PSI: Heavy-duty (concrete, tough stains, large areas)
GPM (Gallons per Minute): This determines cleaning speed. Higher GPM means faster cleaning but more water usage.
Cleaning Units (CU): PSI × GPM = Cleaning Units. This gives you the true cleaning power measurement.

How to Choose the Right Pressure Washer for Your Home
Consider Your Home’s Exterior Materials
Vinyl Siding: 1300-1600 PSI is usually sufficient. Higher pressure can damage or force water behind siding.
Brick and Stone: Can handle 2500-3000 PSI, but start lower and increase as needed.
Wood Siding/Decks: 1200-1500 PSI maximum to avoid wood fiber damage. Always use a wide-angle nozzle.
Concrete: Can handle the highest pressures (2500-3000+ PSI) for effective cleaning.
Size and Portability Factors
Small Homes (Under 1500 sq ft): Electric models like the Sun Joe SPX3000 provide adequate power with easy maneuverability.
Medium Homes (1500-2500 sq ft): Either high-performance electric (Greenworks PRO) or mid-range gas models work well.
Large Homes (2500+ sq ft): Gas models like the Simpson MSH3125 provide the power and capacity needed for efficient cleaning.
Budget Considerations
Under $200: Focus on basic electric models. The Sun Joe SPX3000 offers the best value in this range.
$200-300: Premium electric models or entry-level gas units provide more power and features.
$300+: Heavy-duty gas models and premium electric units offer professional-grade performance.
