Reviews last updated: July 2026 · How we calculate this

What customers like about LEFANT M3

  • Powerful 10,000 to 12,000 PA suction effectively picks up debris and handles carpets
  • Effective dual spinning mops remove stubborn stains and can lift 9mm on carpets
  • Precise LiDAR navigation and obstacle avoidance for efficient cleaning
  • Slim 3.8-inch profile allows cleaning under low furniture
  • Long battery life (up to 220 minutes) cleans large areas on a single charge
  • Auto-empty and mop-washing base station with hot water and drying features

What customers don't like about LEFANT M3

  • App is required for many advanced features, which some users may find inconvenient
  • High performance comes with a higher price tag than budget-only models
  • Mopping requires manual water tank refills at the base station as it lacks onboard capacity

Verdict

The Lefant M3 is a highly automated hybrid robot vacuum and mop that delivers an impressive 12,000Pa of suction power alongside dual pressurized mops spinning at 200 RPM. Guided by 360° dToF laser navigation and a 190° PSD sensor suite, it features a 9mm automatic mop lift for carpets and a sleek 9.7cm slim body to navigate under low furniture. Its prominent advantages include an all-in-one docking station equipped with a 3.2L dust bag lasting 8 weeks, a 2.5L water tank supporting up to 220 minutes of runtime, 45°C hot water mop washing, and a zero-tangle V-shaped brush system. However, its notable drawbacks include its potential to occasionally get stuck or trapped between tightly spaced furniture, a lack of an onboard water tank on the robot itself, and increased operating noise when running on its highest suction levels.
