The Robot Virtual Wall is a useful accessory for robot vacuum cleaners, such as the Xiaomi Mi Robot Vacuum Cleaner. This virtual wall acts as a barrier, preventing the robot vacuum cleaner from entering certain areas of your home. It uses infrared technology to create an invisible boundary that the robot vacuum cleaner cannot cross. This is particularly helpful if you have delicate objects, pet bowls, or specific rooms that you want to keep off-limits to the vacuum cleaner. The Robot Virtual Wall is easy to set up and can be adjusted to create a customized boundary. It is a great addition to any robot vacuum cleaner, providing you with more control over the cleaning process and ensuring that your home is cleaned exactly the way you want it.
