Buying Guide
Key considerations when selecting a 4-stroke pressure washer:
- Engine size and continuous run time: Larger engines deliver sustained power for long cleaning sessions but may be heavier. Consider the job size and how long you’ll operate the unit without breaks.
- PSI and GPM balance: Higher PSI is essential for removing deep grime, while GPM determines cleaning speed. For decks and driveways, a balance like 3400–4400 PSI with 2.0–4.0 GPM is common.
- Portability and stability: Look for wheels, anti-tip design, and a manageable weight if you plan to move the unit around your property.
- Nozzle variety: Quick-connect nozzles (0°, 15°, 25°, 40°, and soap) provide versatility for different surfaces. A soap nozzle or onboard soap tank helps with detergents.
- Fuel and maintenance: Gas models require regular fuel and oil management. Ensure easy access to parts, accessibility for winterization, and service support in your area.
- Accessories and compatibility: Onboard tanks, extension wands, and compatibility with surface cleaners or foam cannons extend capability for patios, fences, and siding projects.
- Use-case perspective: Homeowners typically benefit from a mid-range model (roughly 2500–3800 PSI) for general cleaning, while contractors may opt for higher PSI (4000+ PSI) and durable frames for frequent use.
Overall, 4-stroke gas-powered washers provide portability and robust cleaning performance without relying on electrical outlets. When evaluating models, prioritize PSI/GPM balance, engine reliability, and practical features such as onboard soap tanks and easy nozzle switching to match your specific cleaning needs.
