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
Tapo RV20 Max Plus
- ✓Fast, accurate LiDAR mapping that multiple long-term owners rate above prior Shark/iRobot units
- ✓Ultra-slim 3.3-inch body clears more furniture than typical dock-based robots
- ✓5300 Pa suction with automatic boost on carpet
- ✓Self-empty dock rated for roughly 2 months hands-free with a 3L bag
- ✓H11 HEPA filtration
- ✓Shares the Tapo app with TP-Link's cameras/smart plugs, convenient if already in that ecosystem
- ✓Frequently discounted to around $200 for a self-empty LiDAR robot
- ✗Struggles with slight inclines — lamp bases, fan bases, and thick rubber mats can stall it
- ✗Navigation around irregular, non-linear furniture legs is inconsistent per owner reports
- ✗Needs roughly 5 feet of clear space in front of the dock or it can fail to redock
- ✗No auto mop washing or heated water — mop pad just avoids carpet rather than lifting off it
- ✗At least one owner reports the battery failed around the one-year mark with only a 6-month battery warranty and no replacement battery available
- ✗Some owners report skipped scheduled cleanings
