Upgraded FreeMove Technology 2: The Robot Vacuum has upgraded 6D built-in anti-collision infrared sensors that help the robot vacuum detect probable stuck areas and adjust the cleaning path automatically. Anti-dropping sensors prevent the robot vacuum cleaner from falling off the stairs.
The robot works perfectly! Very good for this price.
