Overview

The M3 series is Lefant's low-cost answer to all-in-one docks, pairing a dToF lidar robot with a dock that empties the bin, washes and dries the spinning mop pads and refills the water. The M3L uses cold-water mop washing, the M3 and M3 Max add hot-water washing, and the M3 Max raises suction to 20,000 Pa. A 23,000 Pa M3 Ultra was listed in Europe but shown as out of stock. Reviewed praised the vacuuming and value but called the software buggy and the mopping only fine, and other reviewers note obstacle avoidance relies on infrared sensors rather than a camera. It sits above the budget M210 Pro in Lefant's lineup and was sold new on Amazon US in October 2026.
