2. Setup Guide
2.1 Unpacking and Assembly
Carefully remove all components from the packaging. Assemble the main body and handle according to the visual instructions provided in the packaging. Ensure all parts click securely into place.
2.2 Charging the Device
Place the Cyber Pro on its charging base. Connect the power adapter to the charging base and a suitable power outlet (100-240V). The LED display will indicate charging status. A full charge provides over 35 minutes of cleaning time.

2.3 Filling the Clean Water Tank
Locate the clean water tank (745ml capacity). Remove the cap and fill it with tap water. For sterilization, the device will electrolyze the water during operation. Do not add cleaning solutions unless specifically designed for this device and approved by the manufacturer.
3. Operating Instructions
3.1 Power On/Off
Press the power button on the handle to turn the device on or off. The LED display will activate upon power-on.
3.2 Cleaning Modes
The Cyber Pro offers different cleaning modes, controllable via the visual LED screen, voice control, or the dedicated APP:
- Electrolyzed Water Mode: Suitable for sterilization, ideal for children's rooms and living areas. This mode uses electrolyzed tap water to kill germs without added chemical components.
- Water Absorption Mode: Designed for quickly absorbing water stains, perfect for bathrooms and kitchens.

3.3 Intelligent Sensor-Detection
The Cyber Pro automatically adjusts suction power and water volume in real-time based on the detected mess on the floor. This optimizes cleaning efficiency and conserves battery power and water.

3.4 Spot Cleaning Spray System
For stubborn or dry stains, press the dedicated button to activate the fixed-point water spray system. This helps to dissolve messes, making them easier to clean.

3.5 Edge Cleaning
The upgraded floor brush features an edge design that allows it to clean close to walls and into corners, ensuring no blind spots are left behind.

4. Maintenance
4.1 Automatic Self-Cleaning and Drying
After use, place the Cyber Pro back on its station base. Press the self-clean button (refer to the manual for exact button location). The device will automatically clean the brush roller and dry it with cold air, preventing odors and mildew.

4.2 Emptying the Dirty Water Tank
The dirty water tank has a 745ml capacity. When the water-level sensor indicates it is full, remove the dirty water tank and dispose of the contents. Rinse the tank thoroughly with clean water before reattaching it to the device.

4.3 Filter Maintenance
The Cyber Pro uses a Cyclone filter type. Regularly check and clean the filter to maintain optimal suction performance. Refer to the full manual for detailed filter cleaning instructions.
5. Troubleshooting
If you encounter any issues with your Viomi Cyber Pro, please refer to the following common troubleshooting steps:
- Device not powering on: Ensure the battery is charged. Place the device on the charging base and check if the charging indicator lights up.
- Poor suction or cleaning performance: Check if the dirty water tank is full and needs emptying. Ensure the clean water tank has sufficient water. Clean the brush roller and filter for any blockages or debris.
- Unusual noises: Turn off the device and check the brush roller and suction path for any foreign objects that might be causing obstruction.
- Water leakage: Ensure both clean and dirty water tanks are correctly installed and sealed. Check for any cracks or damage to the tanks.
