Overview Features Gallery Tech specs Accessories Request a quote

The KEENON M2 is an autonomous indoor disinfection robot that combines four short-wave UV-C lamps with six ultrasonic ultra-dry mist nozzles (particle size below 10 µm) for combined air and surface disinfection with 360-degree coverage. It measures 500 x 500 x 1350 mm, weighs 60 kg, moves at up to 0.8 m/s, needs a minimum passage of 70 cm and runs about 4 hours per charge on a 48 V 15 Ah battery, returning to its charging station autonomously. It navigates with lidar and vision-based positioning, has omnidirectional obstacle avoidance, can ride lifts via an IoT module and has been deployed since 2020 mainly in hospitals, care homes, offices, factories and airports.

Features

M2 emitting dry mist beside a bed in a hospital ward

Spray Disinfection Module

With the size of ultra-dry mist particles below 10 μm, the mist spray is fine and uniform, leaving no dead corner in disinfection. The spray effect meets the Disinfection Technical Specification, and the killing rate of bacteria in the air is as high as 99.9%.

Intelligent Obstacle Avoidance

Equipped with a new 360-degree omnidirectional obstacle avoidance technology, the robot can fully perceive indoor dynamic and suspended obstacles and react instantly to automatically bypass the obstacles.

Multi-robot Collaboration

Through intelligent coordination of the self-developed communication system, AI distribution scheduling can be realized, which ensures multi-robot collaboration and safe and efficient disinfection.

Authority Certification

The robot has passed the inspection and certification of the CMA certification body, and can achieve air + surface disinfection and sterilization.

UV Sterilization Module

The irradiance of the UV lamp is 200 µW/cm² (measured at 1 m distance), meeting the requirements of GB19258 and the Technical Specification for Disinfection. Four sets of short-wave UV-C lamps.

Fully Autonomous Positioning and Navigation

With the industry-leading new composite positioning and navigation technology (deep integration of seven sensing systems such as laser radar, machine vision and depth vision), the robot achieves long-term stable operation in complex environments and a wider range of disinfection.

99.99% Disinfection Rate

The ultraviolet lamp is highly effective against most types of bacteria and viruses, ensuring a 99.99% disinfection rate.

Autonomously Take the Elevator

Equipped with an IoT module, the robot autonomously takes the elevator and chooses the target floor independently, providing automatic, efficient and accurate disinfection and epidemic prevention services across floors.

Convenient and Flexible Operation

Fixed-point disinfection and cruise disinfection modes. When the battery is low, it charges autonomously and can truly run unattended.

Personnel Safety

Fully intelligent operation with human-machine separation to ensure personnel safety; when the robot detects a person approaching within 2 m in front of it during UV disinfection, the UV lamps switch off automatically.

Smart UI

Touch screen with a simple and clear interface for comfortable, convenient operation.
