Buying Guide
Key purchase considerations
- Power and flow: Aim for PSI in the 3200–4200 range with 2.3–4.0 GPM for versatile cleaning across decks, driveways, siding, and vehicles.
- Engine and pump: Four-stroke OHV gas engines and axial cam pumps (as seen in these models) offer durability and consistent performance. Look for thermal relief to prevent overheating on long blasts.
- Nozzles and detergents: A five-nozzle kit (including a soap/foam nozzle) provides flexibility for different surfaces. Onboard soap tanks help with detergent application without extra gear.
- Fuel capacity and runtime: Gas tank size impacts run time. Larger tanks reduce refueling interruptions during big cleaning jobs.
- Hose length and handling: A 25-foot hose is common and practical for most residential tasks. MorFlex hoses or similar flexible lines improve maneuverability and reduce kinking.
- Durability and portability: Welded frames, powder coatings, and pneumatic tires improve longevity and ease of transport around the yard or job site.
- Accessories and compatibility: Check for compatibility with surface cleaners, undercarriage cleaners, foam cannons, or other attachments (often M22 fittings).
- Regulatory considerations: Some models are CARB certified. Verify local regulations and noise concerns if you live in restricted zones.
- Warranty and service: Look for a solid warranty and access to parts for routine maintenance and pump replacement when needed.
