• Carpet Detection: The robot automatically detects carpets and lifts its 8mm roller brush to prevent wetting the carpet while vacuuming.
• dToF Laser Navigation & Mapping: The 15-meter laser scanner creates precise maps of your home, supporting multi-level mapping (up to 3 floor maps). This allows for efficient and blind-spot-free cleaning.
• Obstacle Avoidance: Equipped with PSD 2.0 technology and 12 sensors, the M5 detects and avoids obstacles within 190 degrees, navigating smoothly around furniture and toys.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Lefant M5.

7.1 Roller Self-Cleaning and Drying

• The M5 automatically performs roller self-cleaning when it returns to the base station. The constant-pressure squeegee and 16 fresh water nozzles continuously clean the mop.
• After cleaning, the base station initiates a quiet cool air drying process to prevent odors and keep the mop fresh. You can control the drying time via the Lefant App.

7.2 Automatic Dust Collection and Water Management

• The base station automatically empties the robot's dustbin into a 3.2L dust bag, providing up to 120 days of maintenance-free dust disposal.
• The station also automatically refills the robot with fresh water and discharges wastewater from the robot's dirty water tank.

7.3 Filter Cleaning/Replacement

The M5 uses a HEPA filter. Check and clean the filter regularly. Replace it every 3-6 months, or more frequently depending on usage, to maintain optimal suction performance.

7.4 Brush Cleaning

• V-Shaped Roller Brush: The dual-comb and V-shaped design helps prevent hair tangles. Periodically remove the roller brush and clean any accumulated hair or debris.
• Side Brushes: Check side brushes for wear and tear. Clean any hair or debris wrapped around them. Replace if damaged.
