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 RV30 Max Plus
- ✓Dual LiDAR + IMU navigation that owners switching from Shark/iRobot rate as noticeably more accurate
- ✓True auto mop lift keeps the pad off carpet, not just a route-around
- ✓Suction repeatedly called out by owners as unusually strong for a sub-$250 robot
- ✓3-hour runtime, longer than the RV20 Max Plus
- ✓Self-empty dock rated for roughly 2 months hands-free with a 3L bag
- ✓H11 HEPA filtration and 4 multi-floor map storage
- ✓Handles multi-pet households well according to daily-use owner reports
- ✗A meaningful minority of owners report dock/charging reliability failures, including the robot leaving the dock uncommanded
- ✗300ml water tank needs frequent refills on larger homes
- ✗At least a few owners report a temporary app bug that ignored zone settings and cleaned the whole home
- ✗No auto mop washing or heated water at the dock
- ✗Must re-lock the saved map after edits or it can revert to full-home cleaning, per multiple owner reports
- ✗Occasional false 'stuck brush' aborts reported even when the brush is clear
