8. User Tips
- Pre-soak for Tough Dirt: For heavily soiled surfaces, use the foam sprayer to apply a layer of car wash soap and let it sit for a few minutes before rinsing with high pressure.
- Optimize Battery Life: Always fully charge your batteries before use. For prolonged storage, charge them to about 50% to extend their lifespan.
- Test Spray Patterns: Before cleaning, test the different nozzle spray patterns on an inconspicuous area to find the most suitable one for your task and surface.
- Water Source Flexibility: The integrated bucket allows for great portability. If a tap is nearby, you can also connect the water pipe directly to a garden hose for continuous water supply.
- Safety First: Always wear appropriate eye protection when operating the pressure washer. Keep children and pets away from the operating area.
