Buying Guide: Key Purchase Considerations
- Power and flow: PSI and GPM determine cleaning speed and effectiveness. For large surfaces or heavy grime, seek 3000–4200 PSI with 2.5–4.0 GPM.
- Engine and pump: Look for reliable engines (Honda, Westinghouse CRX) and durable axial cam pumps. Thermal relief features help prevent overheating during longer sessions.
- Portability: Consider weight, wheel type, and handle design. Pneumatic tires and compact frames make transportation easier on uneven ground.
- Hose and nozzle kit: A long, abrasion-resistant hose (like MorFlex) and a full nozzle set (0°, 15°, 25°, 40°, and soap) cover a wide range of tasks from aggressive stripping to delicate rinsing.
- Onboard soap tank: Useful for applying detergents to driveways, siding, and fences without extra containers.
- Setup and maintenance: Look for models with easy assembly and accessible service parts. Regular maintenance extends pump life.
- Noise and emissions: Gas-powered units are louder and emit fumes; ensure usage in permitted areas and follow local guidelines for outdoor use.
- Intended tasks: Match the machine to typical jobs—house siding, decks, driveways, and vehicles—to choose appropriate PSI/GPM and nozzle options.
- Accessories compatibility: If you plan to add surface cleaners or foam cannons, verify M22 fittings and accessory compatibility with the model.
