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
