Setup Guide
- Unpack the Device: Carefully remove the robot, auto disposal station, and all accessories from the packaging.
- Place the Auto Disposal Station:
- Place the station 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 station for optimal navigation.
- Connect the power adaptor to the station and plug it into a power outlet.
- Install Side Brushes: Snap the side brushes into their designated slots on the bottom of the robot.
- Install 2-in-1 Tank: Open the robot's top cover, insert the 2-in-1 tank (dust box and water tank) into its compartment, and close the cover.
- Initial Charging: Place the robot onto the auto disposal station. Ensure the charging contacts align. The robot will begin charging automatically. For first use, fully charge the robot.
- Download Mi Home App: Scan the QR code in the product manual or search for "Mi Home" in your app store (Google Play Store or Apple App Store) to download the application.
- Connect to App:
- Open the Mi Home app and create an account or log in.
- Tap "+" to add a new device. The app should detect the VIOMI Alpha S9 automatically. If not, manually search for it.

Operating Instructions
Using the Mi Home App
The Mi Home app is the primary interface for controlling your VIOMI Alpha S9. It offers comprehensive control and customization options:
- Start/Pause Cleaning: Tap the "Clean" button in the app to start or pause a cleaning cycle.
- Suction Power Adjustment: Select from multiple suction modes (e.g., Quiet, Standard, Strong, Turbo) to suit different cleaning needs.
- Water Level Control: For mopping, adjust the water output level (e.g., Low, Medium, High) based on floor type and desired moisture.
- Mapping and Zoning:
- The robot will create a map of your home during its first cleaning cycle using LiDAR navigation.
- Multi-Floor Mapping: The app supports saving maps for multiple floors (up to 5).
- Virtual Walls & No-Go Zones: Draw virtual boundaries on the map to restrict the robot from entering certain areas.
- No-Mop Zones: Designate areas where the robot should vacuum but not mop (e.g., carpeted areas).
- Area-wise Cleaning: Select specific rooms or areas on the map for targeted cleaning. You can merge, divide, and name map partitions.
- Point Cleaning: Direct the robot to clean a specific spot on the map.
- Scheduling: Set up daily or weekly cleaning schedules for automated cleaning.
- Recharge and Resume: If the battery runs low during a cleaning cycle, the robot will automatically return to the station to recharge and then resume cleaning from where it left off.
Mopping Function
To use the mopping function:
- Fill the 2-in-1 tank with clean water. Do not add cleaning solutions directly to the water tank as it may damage the internal components.
- Attach the reusable wet mop cloth to the mop bracket and then slide the mop bracket onto the 2-in-1 tank. For best results, slightly wet the mop cloth before attaching it.
- Ensure the 2-in-1 tank is properly installed in the robot.
- Select the desired water level in the Mi Home app. The intelligent Y-type mopping pattern simulates manual cleaning for enhanced effectiveness.

Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your VIOMI Alpha S9.
Dust Box and Filter Cleaning
- Remove the 2-in-1 tank from the robot.
- Open the dust box compartment and empty its contents into a trash bin.
- Remove the filter and gently tap it to dislodge dust. You can rinse the filter under running water, but ensure it is completely dry before re-installing.
- Clean the dust box with a dry cloth.
- Re-install the filter and close the dust box.
Main Brush and Side Brush Cleaning
- Turn the robot over.
- Remove the main brush cover and lift out the main brush. Use the provided cleaning tool to cut and remove any tangled hair or debris.
- Pull off the side brushes. Remove any hair or debris wrapped around them.
- Clean the brush compartments and re-install the brushes.
Mop Cloth Cleaning
- After each mopping session, remove the reusable wet mop cloth from the mop bracket.
- Rinse the mop cloth thoroughly under running water until clean.
- Allow the mop cloth to air dry completely before re-attaching or storing.
- Disposable mop cloths should be discarded after use.
Sensor Cleaning
Wipe all sensors (anti-drop, wall, and charging contacts) on the robot and the auto disposal station with a soft, dry cloth regularly to ensure accurate navigation.

Troubleshooting
If you encounter issues with your VIOMI Alpha S9, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Robot does not return to base station after power cut. | Robot may not "remember" its docked state when power is lost. | Manually place the robot back on the station or turn off the robot when it's near the dock and not charging. Ensure the station has stable power. |
| Mop does not clean close to walls/edges. | The mop attachment is not as wide as the robot's body, limiting edge reach. | This is a design characteristic. For thorough edge cleaning, manual spot cleaning may be required. The spinning brush helps with vacuuming edges. |
| Disposable mop cloths leave streaks or are ineffective. | Disposable cloths may not make consistent contact with the floor. | Use the reusable microfiber mop cloth for better mopping performance. Ensure it is properly attached and slightly pre-wet. |
| Map in app appears distorted or overlaid. | Possible software glitch or environmental changes affecting mapping. | Try restarting the robot and the app. If the issue persists, consider re-mapping the area. Ensure no significant changes in furniture layout occur frequently. |
| Robot gets stuck or avoids areas with curtains. | Robot sensors may interpret curtains as obstacles. | Lift curtains or use virtual walls/no-go zones to manage these areas. |
| Robot stops and indicates an obstacle, but none is present. | Dirty sensors or temporary sensor malfunction. | Clean all sensors with a dry cloth. Restart the robot. If persistent, contact customer support. |
| Cannot connect robot to Mi Home app. | Incorrect Wi-Fi settings, Bluetooth off, or network issues. | Ensure your phone's Bluetooth is on. Verify your Wi-Fi is 2.4GHz and has internet access. Restart your router and try the connection process again. |
