The robot detects carpets by ultrasound and raises its 10.5 mm wiping pads to avoid them in wash mode, overcoming obstacles up to 20 mm high. On short and medium pile carpets, it passes efficiently without blocking thanks to its 10,000 Pa power, but for long or thick fringes (over 3 mm), configure it to avoid the area in wash mode to avoid any risk of suction or snagging. In vacuum only mode, it cleans thick carpets well without any noticeable problems. The information available doesn't specifically mention mop carpets, so I'm not completely sure about this particular case.
