5. Setup
5.1 Unpacking and Placement
- Carefully remove all components from the packaging.
- Choose a suitable location for the base station. Ensure it is placed against a wall, with at least 0.5 meters (1.6 feet) of clear space on either side and 1.5 meters (4.9 feet) in front. Avoid areas with direct sunlight or strong Wi-Fi signals from other devices.
- Plug the charging adapter into the base station and then into a power outlet.
5.2 Initial Charging
Place the robot onto the base station. Ensure the charging contacts on the robot align with those on the base station. The robot will begin charging automatically. For first-time use, fully charge the robot before operation (approximately 6 hours).

6. Operation
6.1 Cleaning Modes
The M5 Max offers simultaneous vacuuming and mopping. The pressurized roller mop operates at 280 rpm, ensuring effective cleaning. The robot automatically adjusts suction and mop pressure based on floor type.
6.2 Carpet Detection and Mop Lifting
When the M5 Max detects carpet, it automatically increases suction power and raises the roller mop by 0.3 inches (8mm) to prevent wetting the carpet and ensure optimal vacuuming.

6.3 Obstacle Avoidance
The newly upgraded PSD 2.0 obstacle avoidance system, with its 190° ultra-wide-angle detection, allows the M5 Max to precisely recognize and bypass obstacles, ensuring uninterrupted cleaning.
6.4 App Control & Voice Control
Use the Lefant app to schedule cleanings, select specific rooms, set "No-Clean Zones," and adjust suction/mopping levels. The M5 Max also supports voice control via Alexa and Google Assistant.

7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Lefant M5 Max.
7.1 Self-Emptying Dust Bag
The base station automatically empties the robot's dustbin into a 3.2L sealed dust bag, providing up to 120 days of hands-free dust disposal. Replace the dust bag when full.

7.2 Auto Mop Washing and Drying
The base station uses 167°F (75°C) hot water to automatically clean the roller mop during and after cleaning cycles. After washing, cold air drying prevents odors and protects the mop.
