How to Choose the Right Gas-Powered Pressure Washer?

Before you click “buy,” here’s what to consider:

1. Match PSI & GPM to Your Needs

• Light duty (cars, patio furniture): 1,300–2,000 PSI.

• Medium duty (siding, decks): 2,000–3,000 PSI.

• Heavy duty (driveways, brick): 3,000+ PSI.

2. Engine & Pump Types Matter

Look for well-known engine brands like Honda or Kohler. Avoid low-quality axial pumps—they wear out faster.

3. Nozzle Variety Is Key

Having 0°, 15°, 25°, 40°, and soap nozzles means you can tackle any task safely.

4. Portability & Storage

Big wheels and a compact frame make your life easier—especially if you’re moving around a big yard.
