The Dreame X40 Ultra Complete is equipped with advanced carpet detection and obstacle detection to prevent it from getting stuck on thick carpets. Here are some important functions that make this possible:

- Carpet detection: the robot can recognise carpets and adjust its suction power accordingly to clean effectively without getting stuck.
- Obstacle Detector: The X40 Ultra Complete has laser navigation and object detection that allows it to recognise and avoid obstacles, including carpet edges.
- Liftable mop pads: When passing over carpets, the robot can lift its mop pads to avoid contact with the carpet fibres.

These functions allow the Dreame X40 Ultra Complete to navigate effectively and smoothly over a variety of floor coverings, including thick carpets.
