Lefant N3

Name: Lefant N3
Brand: Lefant
Price: 200 USD
Availability: Discontinued

The N3 is Lefant's step up from bump-navigation bots like the M210 — real LiDAR-plus-dToF mapping instead of random bouncing, and a gimmick that's actually useful: 'sonic mopping' that vibrates the mop pad 12,000 times a minute like an electric toothbrush to work at dried-on stains, rather than just dragging a damp cloth. Ultrasonic carpet detection boosts suction automatically over rugs and switches the mop's cleaning direction so it doesn't drive wet pads onto carpet. Set against name-brand LiDAR robots at this price, the corners cut are real: no self-empty dock (you get a basic charging base), a small 160ml onboard water tank that needs refilling often on anything but a small home, and no auto mop lifting — the mop pad stays attached and just changes direction near carpet rather than physically lifting clear of it. Lefant's own listing doesn't confirm multi-floor map storage, so treat single-floor mapping as the safer assumption. For a standalone LiDAR mapping robot with mopping under $250, it's a reasonable spec sheet from a brand with a real, if thin, US retail presence.

Highlights

True LiDAR + dToF mapping, not bump navigationSonic mopping vibrates at 12,000 strokes/minUltrasonic carpet detection auto-boosts suction

Pros

✓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

Cons

✗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
