Buying Guide
Key Purchase Considerations
- Power vs. flow: Higher PSI helps with stubborn grime but requires adequate GPM to avoid leaving a wet residue. Match PSI and GPM to the task and surface.
- Engine and pump quality: Look for a reliable 4-stroke OHV engine and an axial cam pump for durability and easy maintenance. Engine displacement often correlates with sustained performance.
- Nozzle kit variety: A nozzle set that includes 0°, 15°, 25°, 40° and a soap option provides versatility for different surfaces and detergents.
- Onboard tanks and detergent use: Soap tanks simplify cleaning on large areas. Consider the size of the fuel tank for runtime between refuels.
- Portability and storage: Wheels, handles, and frame construction affect maneuverability and storage in garages or sheds.
- Durability and frame design: Welded steel frames and abrasion-resistant hoses reduce wear and extend the life of the washer in outdoor conditions.
- Regulatory considerations: CARB compliance and other regional rules may influence which models are suitable for use in your area.
- Maintenance needs: Routine checks on oil, pump seals, and hose wear help extend life and maintain performance.
