Key Buying Considerations for Generac Power Washers
Cleaning Applications – Determine if you need a unit for moderate home jobs like vehicles, decks, etc. or more frequent heavy-duty use. Durability and runtime matter most for frequent cleaning.
Portability Type – Stationary units offer ruggedness at a lower price point. Wheeled models provide maneuverability around your property. Cordless power washers run on battery power for ultimate mobility.
Required Pressure – Match the pressure rating (PSI) to your cleaning needs. 2000-2800 PSI suits most homeowner’s occasional cleaning tasks while 3000+ PSI tackles the most stubborn buildup.
Power Source – Gas engines provide continuous use while electric units offer quiet, fume-free operation from a power outlet. Battery powered models run for 30-60 minutes per charge.
Power Supply – Ensure your electric supply or battery capacity meets the requirements to operate the washer under load. Extension cord minimum wire gauge depends on electric power washer amp rating.
Hose Length – Longer hoses up to 50 ft allow accessing a larger area from a single setup position. But they are heavier to move around. Short 15-25 ft hoses offer more maneuverability.
Warranty Coverage – Generac offers 1-2 year limited warranties on residential power washers. Commercial units have shorter 90 day warranties, so opt for an extended commercial warranty.
Carefully matching the power washer specifications and features to your applications results in the most suitable cleaning machine for home or professional use.
Power Washer Use and Care Tips
Follow these proven tips when using your Generac power washer for optimal performance and safety:
- Always test on an inconspicuous spot first to avoid surface damage from excessive pressure. Start at wider angles.
- Maintain a minimum working distance from surfaces based on the pressure rating. Position the nozzle 6-24 inches away to prevent damage.
- When using pressure above 2000 PSI, wear protective gear like closed toe shoes, gloves, eye and ear protection.
- Use the 25-40 degree fan spray tips for most general cleaning purposes. Pencil point zero degree tips are for spot cleaning heavy buildup.
- Allow detergent to soak for 3-5 minutes before rinsing. This allows the chemicals time to loosen caked-on dirt.
- Rinse wooden decks at angles to avoid driving water into wood pores. Limit pressure to prevent stripping paint and damaging softer surfaces.
- Shut off the detergent flow valve when not actively washing to avoid wasting soap. Periodically inspect the detergent filter.
- Follow the manual for any engine oil, pump lubrication, and other periodic maintenance required on your unit. This prevents premature breakdowns.
