Third-party reviews

Based on ratings from across the web.
Reviews last updated: July 2026 · How we calculate this

What customers like about LEFANT N3

  • Ultra-compact design that allows easy cleaning under beds and low furniture without needing to move them.
  • Precise LiDAR dToF navigation, enabling the robot to map the home and follow efficient cleaning paths.
  • Washing function with sonic technology (12,000 vibrations per minute) to remove stubborn dirt.
  • Smart carpet recognition that avoids soaking carpets during washing by lifting fabrics or navigating around obstacles.
  • Excellent value for money compared to other robots with similar advanced features.

What customers don't like about LEFANT N3

  • While suction power is good for daily dust, it may be limited for heavy dirt or long-pile carpets.
  • Like most connected robots, the app requires a stable 2.4 GHz Wi-Fi network for initial setup.
  • The integrated water tank has limited capacity and needs frequent refills when cleaning large surfaces.

Verdict

The Lefant N3 is a 2-in-1 robot vacuum and mop combo that features powerful suction scaling from 4,000Pa up to 6,000Pa alongside advanced dToF LiDAR navigation for precise, real-time 3D home mapping. Its standout characteristics include high-frequency sonic mopping that scrubs floors up to 12,000 times per minute, a 160ml electronic water tank, a 450ml dustbin, and an ultrasonic sensor for intelligent carpet recognition. Main pros highlight a massive 5200mAh battery that delivers a generous 200-minute runtime suitable for large spaces, seamless integration with app and voice controls for setting no-go zones, and its unique ability to automatically dodge rugs while in mopping mode to prevent them from getting wet. On the downside, the vacuum lacks a self-emptying base station, only connects to 2.4GHz Wi-Fi networks, and occasional connectivity dropping issues can complicate user remote controls.
