Lefant M1 Robot Vacuum Cleaner (With Mop)

How does the dToF laser navigation work compared to other robot vacuums?

The dToF (direct Time of Flight) laser navigation uses precise laser measurements to create detailed maps of your home. Unlike cameras or basic sensors, this technology works effectively in low light conditions and provides millimetre-accurate positioning. The robot scans 360 degrees continuously, building a comprehensive floor plan that enables systematic cleaning patterns rather than random movement.

What floor types can the Lefant M1 clean effectively?

The M1 works on hard floors including laminate, tile, hardwood and vinyl, plus low to medium pile carpets and rugs. The 5500Pa suction automatically adjusts between floor types, increasing power on carpets and reducing on delicate surfaces. The mopping function is designed specifically for hard floors and should not be used on carpets or rugs.

How long does it take to charge and how do I know when it needs charging?

The robot takes approximately 4-5 hours to fully charge from empty. The smart app displays battery percentage in real-time and the robot automatically returns to its charging dock when battery drops to around 15%. You'll receive app notifications about charging status and LED indicators on the robot show charging progress with different colours.

Can I set up no-go zones and room-specific cleaning?

Yes, the smart app allows you to create virtual boundaries and no-go zones on the map after the initial cleaning cycle. You can designate specific rooms for targeted cleaning, set different suction levels for different areas and create custom cleaning schedules for individual rooms. The laser navigation ensures the robot respects these boundaries accurately.

How does the mopping function work and what maintenance does it require?

The mopping attachment uses a water tank and microfibre pad that dampens as the robot moves. You fill the tank with water (no cleaning solutions needed), attach the mop pad and select mopping mode through the app. After each mopping session, empty the water tank, rinse the pad and allow both to dry completely to prevent bacteria growth.

What happens if the robot gets stuck or encounters obstacles?

The laser navigation and built-in sensors help avoid most obstacles, but if the robot does get stuck, it will attempt to free itself using various movement patterns. If unsuccessful after several attempts, it sends an alert to your phone with its location. The robot can climb over thresholds up to 2cm high and navigate around furniture legs and cables.

How often should I empty the dustbin and clean the filters?

Empty the dustbin after each cleaning session or when the app indicates it's full. The dustbin capacity handles typical room cleaning but may fill quickly in homes with pets or high dust levels. Clean the HEPA filter weekly by tapping out debris and wash it monthly with water (ensure completely dry before reinstalling). Replace filters every 2-3 months depending on usage.

Does the robot work with 5GHz Wi-Fi networks?

No, the Lefant M1 only connects to 2.4GHz Wi-Fi networks, which is standard for most smart home devices. If your router broadcasts both 2.4GHz and 5GHz, ensure you connect to the 2.4GHz network during setup. Many modern routers combine both frequencies under one network name, so you may need to temporarily separate them or check your router settings for compatibility.
