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
Roborock Q7 L5
