Setup
Initial Preparation

Connect the power cord to the dock and plug it into a compatible 3-prong outlet (110-127V 50-60Hz). Place the robot vacuum onto the charging contacts of the dock. Allow the robot to fully charge before its first cleaning cycle.

Operating Instructions
Navigation and Mapping
The M3 Max uses Precision LiDAR Laser Navigation for 360° real-time scanning, creating accurate home maps for efficient cleaning. It can store multi-floor layouts for up to 3 levels and automatically adapts to different spaces. Advanced Freemove Tech 3.0 enables precise obstacle avoidance, preventing collisions with furniture, cords, and other items. It also automatically avoids stairs and learns no-go zones.
Cleaning Modes and Features
- 20,000Pa Ultra-Strong Suction: Effectively lifts pet hair, dust, and debris from hard floors, tiles, and carpets.
- Complete Edge-to-Edge Cleaning: Side brushes reach 0 mm gaps for 100% corner coverage, and dual spinning mops clean within 1.85mm of edges.
- Smart Carpet Protection System: The robot automatically lifts its mop 9mm when detecting carpets or removes it completely for deep vacuuming. Customize modes via the Lefant App, including Mop Lift, Turbo Carpet Mode, Vac+Mop Combo, Carpet Avoidance, or Carpet Priority Cleaning. Set no-mop zones to protect rugs.
- Dual Spinning Mops: With a powerful 200 RPM spinning speed, these mops deliver deep, efficient cleaning for tough stains.
App and Voice Control
Control your robot effortlessly through the Lefant app, Google Home, or Alexa with just a tap or voice command. The app allows for scheduling, setting no-go zones, targeted zone cleaning, and multi-floor mapping management.

Maintenance
Hands-Free Docking Station
The multifunctional dock provides complete automation with an 8-week 3.2L dustbag, 2.5L water tank, and 113°F hot water mop washing. It features auto cool drying to prevent mop pad warping and built-in detergent dispensing for lasting freshness. The station's base is designed to be removed for quick and easy cleaning.
Tangle-Free Brush System
The Lefant M3 Max features a V-shaped dual-comb brush that actively gathers and cuts through hair, preventing clogs and tangles. This system reduces the need for frequent manual hair removal from the brush.
