5. Setup
Follow these steps to set up your VONROC Cordless Pressure Washer:
- Attach the Nozzle: Securely twist the adjustable nozzle onto the front of the pressure washer unit until it clicks into place.
- Connect the Suction Hose: Attach the quick-connect fitting of the 5-meter suction hose to the water inlet on the bottom of the pressure washer unit. Ensure it is firmly connected.
- Prepare Water Source: Place the filter end of the suction hose into your water source (e.g., bucket, rain barrel, lake). Ensure the filter is fully submerged and the float ball keeps it off the bottom to prevent debris intake.
- Insert Battery: Insert a fully charged VONROC 20V battery pack (sold separately) into the battery slot at the base of the handle until it locks securely.
- (Optional) Attach Detergent Bottle: If using detergent, fill the detergent bottle with your desired cleaning solution. Twist the detergent bottle attachment onto the pressure washer unit, replacing the standard nozzle.

6. Operating Instructions
Once set up, follow these steps for operation:
- Prime the Pump: Before starting, squeeze the trigger for a few seconds to allow water to flow through the pump and expel any air. This helps prevent damage to the pump.
- Start the Pressure Washer: Press the power button or squeeze the trigger to start the unit. The pump will begin to draw water and build pressure.
- Adjust Spray Pattern: Rotate the adjustable nozzle to select the desired spray pattern (e.g., narrow jet for stubborn dirt, wide fan for general cleaning).
- Apply Detergent (if applicable): If using the detergent bottle, ensure it is attached. The pressure washer will automatically mix the detergent with water. Apply to the surface, allow it to soak, then rinse.
- Cleaning Technique: Hold the nozzle at an appropriate distance from the surface. Start with a wider spray and move closer if more pressure is needed. Work in sections, overlapping slightly.
- Stop Operation: Release the trigger to stop the water flow. For longer breaks, remove the battery pack.
- Depressurize: After use, point the nozzle in a safe direction and squeeze the trigger to release any remaining pressure in the system before disconnecting the hose or removing the battery.
7. Maintenance
Regular maintenance ensures optimal performance and extends the life of your pressure washer.
- Clean the Unit: After each use, wipe down the exterior of the pressure washer with a damp cloth. Do not use harsh chemicals.
- Clean Water Filter: Regularly check and clean the filter on the suction hose to prevent blockages and ensure proper water flow. Rinse it under running water.
- Drain Water: Before storing, ensure all water is drained from the unit and hose to prevent freezing damage in cold climates. Run the unit for a few seconds without water until no more water comes out.
- Store Properly: Store the pressure washer in a dry, frost-free location, away from direct sunlight and out of reach of children.
- Battery Care: Store batteries in a cool, dry place. Do not store fully discharged batteries for extended periods.
