2D Map Navigation and Memory Cleaning
The V3S Pro utilizes 2D map navigation to intelligently plan its cleaning path. It maps your home environment and remembers areas it has cleaned and areas it has not. This ensures thorough coverage and prevents repeated cleaning of the same spots, optimizing efficiency and battery life.


Floor Compatibility
The Liectroux V3S Pro is suitable for various floor types, including wooden floors, marble floors, ceramic tiles, and carpets (less than 1cm in height). Its strong suction effectively collects dust and debris from these surfaces.

Cleaning Modes
The robot offers multiple cleaning modes to suit different needs:
- Zigzag Cleaning Mode: The robot cleans in a systematic zigzag pattern, ensuring high coverage and efficiency.
- Along the Wall and Turn Cleaning: The robot cleans along the edges of walls and furniture, ensuring no corner is missed.
- U-shaped Turning Cleaning: This mode helps the robot navigate around obstacles and clean effectively in complex layouts.
- Scheduled Cleaning: Use the app to set specific times for the robot to automatically start cleaning.
- Wet and Dry Mopping: The robot can perform both dry vacuuming and wet mopping. Ensure the correct attachment (dustbin or water tank with mop) is installed for the desired function. The 300ml water tank and 500cm² mop provide effective wet cleaning.


Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your robot vacuum cleaner.
- Empty Dustbin: Empty the dustbin after each use or when full.
- Clean Filters: Tap out or brush the HEPA filter regularly. Replace the HEPA filter every 3-6 months depending on usage.
- Clean Water Tank & Mop: After wet mopping, empty any remaining water from the tank and clean the mop pad. Wash the mop pad thoroughly and allow it to air dry.
- Clean Side Brushes: Check side brushes for tangled hair or debris. Remove and clean them as needed. Replace if worn.
- Clean Sensors: Wipe all sensors (anti-collision, anti-falling, charging contacts) with a clean, dry cloth to ensure they function correctly.
- Clean Driving Wheels: Remove any hair or debris that may be tangled around the driving wheels.
Troubleshooting
If you encounter issues with your Liectroux V3S Pro, refer to the following common solutions:
- Robot not turning on: Ensure the robot is fully charged. Check if the power button is pressed correctly.
- Robot not charging: Verify the charging station is plugged in and powered. Ensure the robot's charging contacts are clean and properly aligned with the charging station.
- Poor cleaning performance: Empty the dustbin and clean the filters. Check if side brushes are tangled or worn. Ensure the suction inlet is not blocked.
- Robot getting stuck frequently: Clear obstacles from the cleaning path. Ensure anti-collision sensors are clean.
- Robot not connecting to WiFi/App: Ensure your WiFi network is 2.4GHz (5GHz is often not supported). Restart your router, robot, and smartphone. Follow the app's connection instructions carefully.
