Buying Guide: Key Considerations for Gasoline Pressure Washers
- Power vs. versatility: Higher PSI and GPM improve cleaning speed but may increase weight and noise. Match power to typical surfaces (concrete, wood, vinyl) and tasks (paint prep, moss removal).
- Engine and pump quality: Look for OHV engines and axial cam pumps for durability and simpler maintenance. A thermal relief valve helps prevent overheating on long sessions.
- Nozzle options: Five-nozzle sets (including 0°, 15°, 25°, 40°, and soap) cover most cleaning jobs. Soap/nozzle combos are useful for detergents and gentle surface cleaning.
- Onboard soap tanks: An onboard reservoir saves trips to refill, especially for larger jobs; check tank capacity and compatibility with detergents.
- Portability and setup: Weigh and measure portability features like wheels and frames. Recoil start vs. electric start impacts convenience; consider hose length and kink resistance.
- Surface safety: For delicate surfaces, prefer lower angles (40° or wider) or dedicated surface cleaners to prevent damage.
- Local restrictions: Some models may have regional sales restrictions or emissions considerations; verify compliance for your area.
