The Xiaomi Mi Robot Vacuum Cleaner provides a convenient way to block specific areas in your home that you don't want the robot to clean. This feature is especially useful if you have delicate objects or areas with cables that you want to protect. To block an area, you can use the virtual wall feature provided by the Mi Robot Vacuum Cleaner. The virtual wall is a device that emits an infrared beam, creating a barrier that the robot cannot cross. Simply place the virtual wall in the desired location, and it will prevent the robot from entering that area. This allows you to have full control over where the robot cleans and ensures that it avoids any sensitive areas. With the ability to block areas, the Xiaomi Mi Robot Vacuum Cleaner offers a customizable cleaning experience tailored to your specific needs.
