4. Setup
4.1 Unpacking and Placement
- Carefully remove all components from the packaging. Retain packaging for future transport or storage.
- Place the all-in-one base on a hard, level surface against a wall. Ensure there is at least 0.5 meters of clear space on both sides and 1.5 meters in front of the base for the robot to maneuver.
- Connect the power cord to the base and plug it into a power outlet. Ensure the cable is neatly stored in the base's rear cable groove to prevent entanglement.
4.2 Initial Charging
Place the robot vacuum onto the charging contacts of the base. The robot will automatically align and begin charging. For first-time use, ensure the robot is fully charged before operation.
4.3 Water Tank Preparation
The base includes a 4L clean water tank and a 4L dirty water tank. Fill the clean water tank with clean tap water. If you have the optional automatic water inlet and outlet device, refer to its specific installation instructions for hands-free water management.

4.4 Mi Home App Connection
- Download the Mi Home App from your device's app store.
- Create or log in to your Mi account.
- Open the app and tap '+' to add a new device. Follow the on-screen instructions to connect your D103CN OMNI Robot Vacuum.
- Once connected, the app will guide you through initial mapping of your home using the robot's LDS intelligent navigation.

5. Operating Instructions
5.1 Starting/Stopping Cleaning
- Via Robot: Press the power button on the robot to start or pause cleaning. Press and hold to send it back to the base.
- Via Mi Home App: Open the app and tap 'Start Cleaning' or select specific areas/rooms to clean.
- Via Voice Control (CN Version): If linked with a XiaoAI Speaker, use commands like "XiaoAI, start cleaning" or "XiaoAI, clean the bedroom."

5.2 Cleaning Modes
The robot supports four primary cleaning modes, configurable via the Mi Home App:
- Sweep Before Mop: The robot first vacuums and then mops, adhering to traditional cleaning habits.
- Sweep and Mop Combined: Simultaneous vacuuming and mopping for efficient cleaning.
- Sweep Only: For dry cleaning and dust collection.
- Mop Only: For wet cleaning without vacuuming.
You can also adjust suction power and water volume settings within the app to suit different floor types and cleaning needs.

5.3 Intelligent Features
- Edge Cleaning: The innovative mechanical arm extends to clean edges and corners at a millimeter level, achieving up to 99% coverage.
- Mop Lifting: The robot automatically lifts its mop pads when detecting carpets or returning to the base to prevent wetting and secondary contamination.
- Obstacle Avoidance: Equipped with 110° wide-angle laser detection and S-Cross™ structured light, the robot intelligently avoids obstacles and prevents falls.
- Scheduled Cleaning: Set specific times for cleaning tasks via the Mi Home App.
- Restricted Areas: Define no-go zones or virtual walls in the app to prevent the robot from entering certain areas.
- Smart Home Integration: Supports Xiaomi HyperOS for linking with other Xiaomi smart devices, enabling automated cleaning scenarios (e.g., cleaning when you leave home).

6. Maintenance
Regular maintenance ensures your robot vacuum operates efficiently and extends its lifespan.
6.1 Self-Cleaning Base Maintenance
- Mop Washing and Drying: The base automatically washes and hot-air dries the mop pads. Ensure the clean water tank is filled and the dirty water tank is emptied regularly.
- Dust Collection: The base automatically empties the robot's dustbin into an antibacterial dust bag. Replace the dust bag approximately every 75 days or when full.
- Cleaning Tray: Periodically clean the cleaning tray in the base to remove any residue.

6.2 Robot Vacuum Maintenance
- Main Brush: The innovative hair-cutting main brush minimizes tangling. However, periodically check and clean the main brush for any remaining hair or debris. The optimized shaft structure reduces hair entanglement.
- Side Brush: Inspect the side brush for wear and tear. Replace if bristles are damaged or bent.
- Dustbin and Filter: Although the base auto-empties the dustbin, occasionally remove and clean the dustbin and its HEPA filter. Tap out dust and rinse if necessary (ensure completely dry before re-inserting).
- Mop Pads: While the base cleans them, inspect mop pads for excessive wear or stubborn stains. Replace as needed.
- Sensors: Gently wipe all sensors (laser detection, cliff sensors, obstacle avoidance sensors) with a clean, dry cloth to ensure accurate navigation.

7. Troubleshooting
If you encounter issues with your robot vacuum, refer to the following common problems and solutions:
- Robot not cleaning effectively:
- Check if the dustbin is full or the filter is clogged.
- Ensure mop pads are clean and properly attached.
- Verify that the main brush and side brush are free of debris.
- Increase suction power or water volume in the Mi Home App.
- Robot gets stuck or navigates poorly:
- Clean all sensors on the robot.
- Remove any small obstacles or loose cables from the cleaning path.
- Ensure the environment is well-lit for optimal navigation.
- Re-map the area via the Mi Home App if the map is inaccurate.
- Mop pads are not lifting on carpets:
- Ensure carpet detection is enabled in the Mi Home App.
- Clean the carpet sensors on the underside of the robot.
- Hair tangling on the main brush:
- While the brush has a hair-cutting feature, long hair may still accumulate. Periodically remove the main brush and clean any wrapped hair.
- Base not self-cleaning or emptying dust:
- Check if the dust bag in the base is full and needs replacement.
- Ensure the clean water tank is filled and the dirty water tank is emptied.
- Verify that the robot is correctly docked on the base.
- App connectivity issues:
- Ensure your Wi-Fi network is stable and the robot is within range.
- Restart the robot and your router.
- Try re-pairing the robot with the Mi Home App.
For persistent issues, consult the Mi Home App for specific error codes or contact customer support.
8. User Tips
- Pre-Clean for Best Results: While the robot is smart, quickly picking up large debris or loose items before a cleaning cycle can enhance efficiency and prevent potential jams.
- Optimize Base Placement: Position the all-in-one base in a central location with good Wi-Fi coverage and ample clear space for the robot to easily dock and undock.
- Utilize App Features: Explore the Mi Home App's advanced features like scheduled cleaning, zone cleaning, and virtual walls to customize cleaning routines for your specific home layout and needs.
- Regular Sensor Cleaning: Dust and debris can accumulate on sensors, affecting navigation. A quick wipe down of all sensors before each cleaning session can prevent issues.
- Empty Water Tanks Promptly: For optimal mopping and self-cleaning, ensure the clean water tank is always filled and the dirty water tank is emptied after each mopping cycle.
- Child Lock Function: Activate the child lock function via the app to prevent accidental operation by children or pets.
