Reviews last updated: July 2026 · How we calculate this

What customers like about LEFANT M320

  • Ultra-slim design about 2.8 inches high fits beneath furniture and sofas
  • High suction up to 6,000 Pa effectively collects pet hair
  • Excellent value for money and often available at a discount
  • Responsive technical support for issues such as the water tank
  • Washable filters reduce maintenance costs
  • Suitable for daily floor maintenance

What customers don't like about LEFANT M320

  • The app can be limited in its error notifications
  • App setup is often restricted to 2.4 GHz Wi-Fi
  • Not intended for deep cleaning, primarily for maintenance
  • Navigation can be unpredictable and random on some entry-level versions

Verdict

The Lefant M320 is a compact 3-in-1 robot vacuum and mop featuring a slim 7.9cm profile, a brushless suction port to prevent hair tangles, and a large 800ml visible dustbin. Driven by a 4000mAh battery that delivers up to 210 minutes of runtime, it provides an impressive 6000Pa of suction power alongside ultrasonic carpet detection and a 9-sensor PSD triangular obstacle avoidance system. Main pros include its highly efficient pet hair removal, its ability to automatically boost suction or avoid carpets based on whether the magnetic mop holder is attached, its quiet operation, and compatibility with Alexa/Google Home voice controls. However, notable cons include its dependency on 2.4GHz Wi-Fi with occasional connectivity drops, less reliable mapping accuracy via the app, and poor cleaning performance on high-pile carpeting.
