Lefant M320

Manufacturer: Lefant

The Lefant M320 is a robot vacuum cleaner that covers a solid range of automated cleaning needs, from scheduled runs to auto docking and anti-fall protection. It supports mapping and route mapping, allowing it to navigate methodically rather than at random, and includes problem area cleaning for more focused attention where it counts. Twin side brushes and compatibility with both Google Assistant and Alexa add further practical value to its feature set.

On the technical side, the M320 delivers 6000 Pa of suction power across 6 cleaning modes and is rated to handle all floor types, including basic mopping. Its 4000 mAh battery supports up to 210 minutes of runtime per charge, with a full recharge taking around 4 hours. The dustbin holds 0.45 litres, and the unit weighs 3460 g with a low 79 mm profile. A HEPA filter and allergy filter are both included, and the robot features auto-off functionality for energy management.

Pros
  • Mapping and route mapping allow the robot to clean in an organised, methodical pattern rather than moving randomly
  • At 79 mm tall, the low-profile body can navigate under furniture without difficulty
  • A 210-minute runtime per charge supports extended cleaning sessions without interruption
  • Both a HEPA filter and an allergy filter are included, offering two layers of filtration for airborne particles
  • No-go zone support lets users define areas the robot should not enter
  • Anti-stuck and anti-fall sensors help it handle real-world floor layouts with fewer interruptions
Cons
  • Not self-emptying, so the 0.45-litre dustbin requires manual emptying after use
  • Does not support virtual barriers, limiting boundary control to software-defined no-go zones only
  • The battery is not removable, and there is no overheating indicator
  • Mopping is listed as a feature but water level adjustment is not supported, reducing mopping flexibility
  • A 4-hour charge time is relatively long given the robot cannot be easily swapped to a spare battery
  • No dirt sensor means the robot cannot automatically increase cleaning effort in heavily soiled areas
Who is this for?

The Lefant M320 is well suited to households that want a largely hands-off cleaning routine, thanks to its scheduling, auto-docking, and 210-minute runtime that allow it to run and return to base without user involvement. Its mapping and route mapping capabilities make it a reasonable fit for medium-sized homes where methodical coverage matters, and the combination of a HEPA filter and allergy filter makes it particularly relevant for users who are sensitive to dust or airborne particles. The low 79 mm height also makes it a practical choice for homes with furniture close to the floor, where a taller unit would simply be unable to reach.

Who is this NOT for?

Users who want a fully autonomous setup with minimal maintenance may find the M320 limiting, as it lacks a self-emptying base and requires the dustbin to be cleared manually after each session. Those looking to use the mopping function with any real control will also be disappointed, since water level adjustment is absent and there is no mop raising or drying capability, making wet cleaning fairly basic. Additionally, households that rely on a dedicated home automation app or need virtual barrier support for more precise boundary management will find those options missing here.

Final Verdict

The Lefant M320 is a capable robot vacuum that covers the core bases well — methodical navigation through mapping and route mapping, a long runtime, solid filtration, and enough automation to suit everyday cleaning without constant oversight. Its 6000 Pa suction across 6 cleaning modes combined with all-floor compatibility gives it genuine versatility on the cleaning side, while smart home integration via Google Assistant and Alexa adds convenience for connected households. That said, the absence of a self-emptying base and limited mopping functionality mean it is better positioned as a solid daily-use vacuum than a fully autonomous or multi-function cleaning system. For users whose primary need is reliable, scheduled vacuuming with structured navigation and good filtration, the Lefant M320 delivers a focused and competent package.
