Pros & cons
Lefant M310 Ultra
- ✓ToF LiDAR navigation with confirmed multi-layer map surveying
- ✓190° PSD obstacle avoidance claims millimeter precision, including in darkness
- ✓6000 Pa suction, stronger than several Lefant siblings
- ✓170-minute runtime covers larger homes without a mid-clean charge
- ✓Four selectable cleaning patterns (plan, random, along-the-wall, fixed-point)
- ✓Ultra-slim 3-inch body clears more furniture than typical LiDAR robots
- ✗No self-empty dock — manual dustbin emptying only
- ✗No dustbin or water tank capacity published
- ✗No weight or full dimensions published
- ✗Carpet handling is avoidance via manual mop-holder removal, not an automatic mechanical lift
- ✗No noise level or HEPA/filtration rating published
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
