Reviews last updated: July 2026 · How we calculate this

What customers like about LEFANT M350

  • Strong 6000Pa HyperForce suction power effectively lifts dust, debris, and pet hair.
  • Efficient ToF LiDAR navigation creates detailed real-time maps for structured cleaning routes.
  • Reliable PSD obstacle avoidance prevents the unit from colliding with furniture or getting stuck on cords.
  • Convenient 75-day self-emptying base station significantly reduces manual maintenance.
  • Versatile 3-in-1 capabilities let it sweep, vacuum, and mop floors in a single pass.
  • User-friendly Lefant mobile app makes it easy to schedule sessions and set customized no-go zones.

What customers don't like about LEFANT M350

  • Mobile application only supports 2.4G Wi-Fi networks and cannot connect to 5GHz bands.
  • The software and mapping functions occasionally require manual resets if the robot struggles to find its base station.
  • Customer service can sometimes be slow to respond or restrictive regarding warranty repairs without an original receipt.
  • Suction performance is less effective on thick or high-pile carpets compared to hard flooring.

Verdict

The Lefant M350 is a 3-in-1 self-emptying robot vacuum and mop combo that delivers a powerful 6,000Pa of suction alongside an integrated 300ml water tank and a 150ml internal dustbin. Guided by a 360° ToF LiDAR navigation system and a 190° PSD obstacle avoidance system, it maps the home in real time to plan efficient routes while easily gliding under low furniture thanks to its slim 7.9 cm height profile. Its primary advantage is an ultra-convenient hands-free maintenance routine courtesy of a charging station equipped with a 2.2L dust bag that can hold up to 75 days of debris, all powered by a lithium-ion battery delivering up to 140–150 minutes of runtime. The main downsides are its reliance on a sponge-type filter rather than a true HEPA alternative and smart app customizations like zone management and scheduling only supporting a 2.4GHz Wi-Fi network connection.
