Equipped with precision Lidar and dToF sensors, this smart cleaner promises efficient navigation and thorough cleaning, whether it’s vacuuming fine dust or tackling pet hair. With up to 4000Pa suction power,ultrasonic carpet detection, and sonic mopping technology that aims to scrub stubborn stains, the N3 is clearly designed to be an all-in-one solution for busy homes. Plus, the convenience of WiFi, app, and alexa controls adds a modern touch to managing our cleaning routines. In this review, we’ll share our firsthand experience with its strengths, quirks, and how it fits into everyday life.
Overview of Our experience with the lefant N3 Robot Vacuum and Mop Combo

Our experience with this robot vacuum and mop combo has been largely positive, especially considering its advanced navigation and powerful suction. The precision mapping powered by Lidar and dToF sensors allowed it to create highly accurate room layouts, helping the robot clean efficiently and avoid obstacles. The ultrasonic carpet detection impressed us as it automatically boosted suction when transitioning onto rugs and smartly avoided wetting carpets during mopping cycles. With up to 4000Pa suction, it easily handled everything from fine dust and pet hair to crumbs on hard floors. We also appreciated the variety of suction modes, wich gave us good control based on the mess and floor type. Its sonic mopping technology, featuring 12,000 scrubs per minute, made light cleaning streak-free, though tougher stains occasionally required pre-dampening the mop pad for best results.
Using the companion app was intuitive and unlocked several convenient features like customizable no-go zones, selective room cleaning, and scheduling. Integration with Alexa and Google Home added hands-free control, which really simplified day-to-day operation. The robot ran for over 3 hours on a single charge, covering a large 3200 sqft home before automatically docking to recharge and resuming cleanup. Even though the vacuum portion consistently delivered excellent cleaning, the mop pads showed some wear after a couple of months, and finding replacements was a minor pain point. Here’s a brief summary of features and how they stacked up during our testing:
