3. Operating Instructions

3.1 Starting a Cleaning Cycle

• Manual Start: Press the power button on the robot or the base to initiate a cleaning cycle.
• App Control: Open the Mi Home app. From the device interface, you can start, pause, or stop cleaning.

3.2 Intelligent Navigation and Cleaning

• Lifting Laser Navigation: The robot uses advanced laser navigation to map your home and plan efficient cleaning paths. Its body can lift or lower to navigate under low furniture (as thin as 8.8cm).
• Edge and Corner Cleaning: Equipped with retractable dual robotic arms, the robot can sweep and mop precisely along walls and into corners, ensuring thorough coverage.
• Obstacle Avoidance: Multiple obstacle avoidance sensors and triple laser real-time scanning help the robot detect and navigate around obstacles, preventing it from getting stuck or bumping into furniture.

3.3 Suction and Mopping

• Powerful Suction: The robot delivers 23000Pa suction power to effectively pick up dust, hair, and debris from various floor types.
• Mopping Function: The integrated mopping system, combined with the self-cleaning base, ensures floors are thoroughly cleaned. The main unit has an independent water tank for precise water volume control.

4. Maintenance

4.1 Self-Cleaning Base Maintenance

• Mop Washing and Drying: The base automatically washes the mop with 80°C hot water to dissolve stubborn stains and then dries it with hot air for up to 2 hours, preventing odors and mildew.
• Dual Scraper Arms: The base features dual scraper arms that clean the base itself during mop washing, reducing stain accumulation.
• Automatic Water Management: For models with automatic water supply and discharge, ensure the connections are secure. The base also automatically adds detergent.

4.2 Dust Collection and Disposal

• The base automatically collects dust from the robot's dust box into a disposable dust bag.
• The dust bag typically needs replacement every 75 days, depending on usage and environment. The base includes a thoughtful storage compartment for spare dust bags.

4.3 Robot Components Cleaning

• Main Brush: The robot features a double-blade hair-cutting main brush that cuts and collects hair in real-time, reducing entanglement. Periodically check and clean the main brush as needed.
• Side Brushes: The retractable dual robotic arms (side brushes) should also be checked for debris and cleaned.
• Filter: The robot uses a HEPA filter. Clean or replace the filter regularly according to usage to maintain optimal suction performance.
• Sensors: Wipe the robot's sensors with a soft, dry cloth to ensure accurate navigation.

5. Troubleshooting

• Robot not connecting to Mi Home app: Ensure your Mi Home app region is set to "China Mainland" and Bluetooth is enabled on your phone. Try resetting the robot's network connection if issues persist.
• Robot getting stuck frequently: Check for low-lying obstacles or cables that might be trapping the robot. The robot's intelligent navigation with low space prediction should minimize this, but some environments may require pre-cleaning.
• Reduced suction power: Clean the dust box, main brush, and HEPA filter. Ensure the dust bag in the base is not full.
• Mop not cleaning effectively: Check the water tank levels in the base. Ensure the mop pads are clean and properly attached.
• Unusual odors from the base: Ensure the mop pads are thoroughly dried after cleaning cycles. Clean the base's water tanks and scraper arms.
