2. Setup Instructions
- Assemble the Pole: Extend the telescopic pole to your desired length by twisting the locking mechanisms counter-clockwise to loosen, extending the sections, and then twisting clockwise to secure. Ensure all sections are firmly locked before use.
- Attach Cleaning Head: Select either the multi-purpose brush head or the 2-in-1 window cleaner attachment. Align the attachment with the end of the pole and secure it firmly.

Use the ball valve on the hose connection to control the water flow to the brush head.
- Apply Soap (if using): If the soap dispenser is filled, activate the soap flow by adjusting the dispenser's setting.
- Cleaning Surfaces:
- General Cleaning (Brush Head): Use the multi-purpose brush head with its soft bristles for gentle yet effective cleaning of solar panels, walls, and large vehicles. Move the brush in a consistent motion across the surface.

4. Maintenance
- Clean Attachments: After each use, rinse the brush head and window cleaner attachment thoroughly with clean water to remove any dirt or soap residue. Allow them to air dry completely.
- Drain Pole: Disconnect the hose and allow any remaining water to drain from the telescopic pole. This prevents water stagnation and potential damage.
- Store Properly: Retract the telescopic pole to its shortest length for compact storage. Store the brush and all accessories in a clean, dry place, away from direct sunlight and extreme temperatures.
- Check Connections: Periodically inspect all hose connections and locking mechanisms for wear or damage. Replace any worn parts to ensure optimal performance and safety.
5. Troubleshooting
| Problem | Possible Cause | Solution |
