Buying Guide: Key Purchase Considerations
- Power and flow: For cars, a balance of PSI (pressure) and GPM (flow) is essential. Higher PSI with adequate GPM helps remove brake dust and road grime without excessive scrubbing, while too much pressure can risk damage to paint if not controlled with the right nozzle.
- Engine type: Gas engines provide maximum power and mobility but require fuel and maintenance. Electric models offer quiet operation and lighter weight but may lack the same sustained depth of cleaning for heavily soiled vehicles.
- Nozzle options: A multi-nozzle setup (0°, 15°, 25°, 40°, plus soap) provides versatility for different surfaces and stain levels. A soap nozzle or onboard soap tank simplifies applying detergents to the vehicle’s exterior.
- Portability and storage: Look for models with large wheels, stable frames, and manageable weight for moving around a car. Onboard storage for hoses and nozzles helps keep a tidy workspace.
- Durability and maintenance: Axial cam pumps and sturdy engines support longer lifespans. Check for CARB/EPA compliance if required, and review maintenance tasks like oil changes and fuel handling.
- Accessories compatibility: If you already own surface cleaners, foam cannons, or undercarriage cleaners, confirm compatibility with common fittings (such as M22) to maximize versatility.
