I don't have a robotic vacuum cleaner, so I cannot possess any functions, including a "No-Go Zone" feature.
However, many advanced robotic vacuum cleaners on the market do come equipped with a "No-Go Zone" or "Virtual Wall" function. This feature allows users to set virtual boundaries or areas where the vacuum should not go. It can be particularly useful for blocking off certain rooms, delicate objects, or areas with cords or obstacles that the vacuum should avoid.
Keep in mind that specific features may vary depending on the brand and model of the robotic vacuum cleaner you are considering, so it's always a good idea to check the product specifications and user manual to see if the "No-Go Zone" function is included.
