How to reset the map of the robot vacuum cleaner Xiaomi: all ways for Mi Home and Dreame

Xiaomi’s robot vacuum cleaners are some of the most popular smart cleaning devices, but even they sometimes require reloading navigation data. Resetting a card may be necessary after moving, rearranging furniture, working errors, or updating a firmware.

In this article, we will discuss all the current ways to reset the map for Mi Robot Vacuum, Dreame, Viomi and other models, including devices with LiDAR and cameras. Particular attention will be paid to the nuances of new firmware versions (2023-2026), where the manufacturer changed the logic of the navigation system, you will learn how to reset the map through the Mi Home application, physical buttons on the case, and what to do if standard methods do not work.

Why Xiaomi robot vacuum cleaner loses map and when to reset it

A navigation map is a digital footprint that a robot creates during cleaning by remembering the location of walls, furniture and obstacles, stored in both the device's memory and in the Xiaomi cloud (if synchronization is enabled), but the map can get lost or become irrelevant for several reasons:

• 🔄 Furniture rearrangement – if you move a sofa, wardrobe, or add new items, the robot will try to navigate by outdated data.
• 🏠 Moving – when moving to another apartment, the map of the previous housing becomes useless.
• 🤖 Firmware errors – after software updates, some models (for example, Dreame) D9 Mi Robot Vacuum-Mop 2 Pro can forget saved cards.
• 🔋 Reset to factory settings – a full reboot of the device automatically deletes all navigation data.
• 📡 Wi-Fi problems – if the robot can’t sync to the cloud, the map may be duplicated or distorted.

How do you know if it's time to reset your card?

• 🚫 The robot does not recognize areas that it has previously bypassed (for example, a nursery or a pet feeding place).
• 🌀 The device moves chaoticly, often encounters obstacles or takes a long time to "think" before maneuvers.

What to do if the card is not reset: common mistakes and decisions

Sometimes standard card reset methods don't work, and it could be due to firmware, hardware malfunctions, or synchronization errors, and let's look at the typical problems and the ways in which they can be solved.

Problem 1: Once reset, the map is not rebuilt.

• 🔹 Make sure there is enough lighting in the room – LiDAR and cameras work worse in the dark.
• 🔹 Reboot the robot (hold on) ⏻ 5 seconds).

Problem 2: The app displays an old map despite being reset.

• 🔹 Clear the Mi Home app cache in your phone settings.
• 🔹 Remove the robot from the app and add it again.
• 🔹 Check if Cloud Sync is enabled – if so, turn it off before resetting.

Problem 3: The robot makes the error "It is impossible to build a map."

• 🔹 Wipe the lidar (round glass on the top panel) and the cameras with a soft napkin.
• 🔹 Make sure there are no mirrors or glass surfaces in the robot’s path – they knock navigation down.
• 🔹 Update the firmware through Settings → Update of the PO.

If none of these methods worked, and the robot is still not building the map, the reason could be a malfunction of the LiDAR sensor or motherboard, which requires a diagnosis at the service center.
