Lefant N3 vs Lefant M2S Pro

Quick take: The Lefant M2S Pro costs $20 less; the Lefant M2S Pro has stronger suction (10,000 vs 4,000 Pa); the Lefant M2S Pro runs longer per charge (240 vs 150 min).

Which one to buy

Lefant's cheaper robot is the better one here. The M2S Pro costs $20 less than the N3 and adds a self-empty station rated for 90 days, saved maps for up to three floors, a rated 10000 Pa against 4000 Pa, and 240 minutes of runtime against 150. Its water tank is also larger at 300 ml, where the N3's 160 ml needs frequent refills.

The N3 has two real points in its favor. Its sonic mop vibrates the pad 12,000 times a minute, which does more for dried-on spills than the M2S Pro's plain drag pad. It also carries a 450 ml bin, though with the M2S Pro's dock emptying a 150 ml bin for you, that matters less than it looks. Neither lifts its mop or washes it.

The N3 is now discontinued with no successor, so the M2S Pro is also the only one still sold. Buy the Lefant M2S Pro unless you mostly care about mopping sticky hard floors in a small, single-level home, where the N3's sonic pad was the one feature worth paying more for.

Lefant N3

Suits you if scrubbing dried stains off hard floors is the main job and you live on one level, since its sonic mop is the only feature it wins on; now discontinued, with no successor.

Lefant M2S Pro

Made for almost any home: it is $20 cheaper and adds self-emptying, multi-floor maps and longer runtime.

Pros & cons

Lefant N3

  • ✓True LiDAR + dToF navigation with no-go zones and spot cleaning via the app
  • ✓Sonic mopping technology tackles dried stains better than a passive drag mop
  • ✓Ultrasonic carpet detection auto-boosts suction and avoids over-wetting rugs
  • ✓4 adjustable suction levels up to 4000 Pa
  • ✓Works in full darkness since it doesn't rely on a camera
  • ✓Alexa/Google Assistant and app scheduling included
  • ✗No self-empty dock — just a basic charging base, so the 450ml bin needs manual emptying
  • ✗Small 160ml water tank needs frequent refills on larger homes
  • ✗No physical mop lift — the pad changes direction near carpet rather than lifting off it
  • ✗Multi-floor map storage isn't confirmed in Lefant's own listing
  • ✗No published HEPA/filtration rating or noise level

Lefant M2S Pro

  • ✓dToF LiDAR with genuine multi-floor mapping and up to 3 saved maps
  • ✓Bagless 90-day self-empty station, with an optional bag for odor control
  • ✓PSD obstacle avoidance with 9 sensors across 190°, works in the dark, plus 4 anti-drop sensors
  • ✓Granular app control — 4 suction levels, 3 water-flow levels, zone split/merge, do-not-disturb
  • ✓Long 240-minute runtime off a 5200mAh battery
  • ✓Quiet mode rated under 60 dB
  • ✓HEPA filters included, and a meaningfully lower price than comparable self-empty LiDAR robots
  • ✗No auto mop washing or heated water at the dock
  • ✗Mop pad avoids carpet rather than mechanically lifting off it
  • ✗Small 150ml dustbin between empties (mitigated by the self-empty station)
  • ✗300ml water tank needs refilling on larger homes
  • ✗14.2 lbs listed item weight likely includes the station, so true robot weight is unclear

Lefant N3 vs Lefant M2S Pro: common questions

Is the Lefant N3's sonic mopping worth giving up the M2S Pro's self-empty dock?▾

For most homes, no. The sonic pad helps with dried stains on hard floors, but the M2S Pro's dock saves you emptying the bin for up to 90 days and costs $20 less.

Can the Lefant N3 map more than one floor?▾

Lefant does not confirm multi-floor map storage for the N3, so plan on a single map. The M2S Pro saves up to three maps, which makes it the clear choice for a multi-level home.
