Update of the robot vacuum cleaner Xiaomi: what is new and how to install

The modern robot vacuum cleaner is no longer just a mechanical brush with a motor; it is a full-fledged IoT device that requires regular digital hygiene. Owners of Xiaomi, Roborock or Viomi equipment often notice that after the release of a new version of the software, the mapping algorithm changes, sensors work better or new cleaning scenarios appear. Ignoring notifications about the availability of a new firmware can lead to the fact that your gadget will not be able to properly interact with new versions of the mobile application or smart speakers.

The upgrade process is not just a formality, but a way to implement critical security patches and optimize energy consumption. Developers are constantly improving navigation algorithms, allowing the device to more effectively bypass obstacles and more accurately build a map of the room. If you notice that the vacuum cleaner has begun to “lose” in a familiar room or sucks up dust worse, it is likely that the software failure can be fixed by installing the current version of firmware.

In this article, we will discuss in detail what changes the latest updates bring to the Xiaomi ecosystem, how to properly conduct the procedure so as not to turn smart equipment into a “brick”, and what hidden opportunities open up after an update. You will learn about the intricacies of working with servers, the differences between the global and Chinese versions, and how to force the search for updates if the automatic mechanism fails.

⚠️ Warning: Before starting any update, make sure that the battery is at least 60% charged. Interrupting the recording process at low charge can cause permanent damage to the system software.

Key changes in the latest firmware versions

Changelog analysis from recent months shows that developers have shifted their focus from adding new features to optimizing stability. Whereas earlier each update gave new wash modes or types of carpets, now the priority has been maps and integration with voice assistants. Users have complained massively about the maps’ “grid” after the router reboot, and Xiaomi engineers have responded by releasing patches that improve the caching of data on the robot’s internal drive.

Special attention is paid to obstacle recognition algorithms in LDS and dToF lidar models. New firmware often includes updated neural network models that allow the robot to distinguish wires and socks from static objects. This reduces the likelihood of getting stuck and improves overall cleaning efficiency. In addition, the logic of virtual walls has been improved: now the forbidden areas are observed with an accuracy of up to a centimeter, rather than with a margin of error of 10-15 cm, as was the case in older versions of the software.

Another important aspect is the support for new Wi-Fi protocols and security standards. Mi Home periodically changes the requirements for encrypting transmitted data. If the robot vacuum cleaner has not been updated for a long time, it may simply stop connecting to the cloud and you will lose the ability to control it remotely.

• 🚀 Improved speed of construction 3D-room maps and positioning accuracy in the dark.
• 🔋 Optimized algorithm return to base: the device now more economically consumes charge on the way.
• 🗣️ Support for voice commands for Yandex.Alice and Google Assistant through new gateways.
• 🧹 Improved logic of carpet bypass with wet cleaning mode enabled.

Preparation of the device for installation of updates

Before you click the Update button, you need to perform a series of preparatory steps that ensure the successful completion of the process. First rule: stable connection. The robot must be in the zone of confident reception of the Wi-Fi signal, preferably on the same network to which your smartphone is connected. Use of guest networks or networks authorized through the web page (captive portal) is unacceptable — the device simply will not be able to communicate with the update server.

The second critical point is cleaning the dust collector and checking the charging station contacts. If the contacts on the dock or the robot itself are oxidized or contaminated, the device can interrupt charging during the upgrade process, which will lead to battery discharge. Wipe the contacts with dry cloth and make sure that the charging indicator is on with even light, rather than flashing, signaling an error.

It is also recommended to check the free space in the Mi Home application. Sometimes the application cache grows to giant sizes, which prevents the correct loading of firmware files. Go to the profile settings in the application and clear the cache if it takes more than 100 MB. This will speed up data transfer and reduce the risk of errors when checking the checksums of the file.

Don't ignore checking the version of the controller application itself. It often happens that a new robot firmware requires an up-to-date version of Mi Home or Roborock to correctly interpret the new settings. If you try to update your device through an old application, the process can freeze at 99%, since the interface will not know how to handle the new configuration settings.

Step-by-step: how to update the robot software

There are two main ways to update: automatic (through push notification) and manual (through device menus). Most often, the system itself reports the availability of a new version, but if you want to check for an update forcibly, follow the instructions below. Make sure that the robot is connected to the charging station and the status indicator does not flash orange.

Open the Mi Home app on your smartphone and go to the home page where all connected devices are displayed. Find your robot vacuum cleaner card. In the top right corner of the card or inside the control menu (usually under the on button or in the three-dot menu) there will be an icon with device information. Click on it to see the current version of firmware.

Path to Update: Home → Device Card → Three Dots (top right) → Check Updates

If the system detects a new version, a pop-up will appear describing the changes and the Update button. Press it and wait until the download is complete. At this time, the robot can emit an audible signal and go to sleep. Do not close the application or switch to other heavy tasks on the phone so as not to break the connection. The process can take from 5 to 20 minutes depending on the Internet speed and file size.

⚠️ Warning: During the upgrade, the lights on the body may flash or go out chaotically, and it is strictly forbidden to carry the robot, press buttons or remove it from the dock until the process is complete.

Once installed successfully, the robot will automatically restart, and you'll see a message in the application that it's a successful update, and you'll need to recheck the settings, and sometimes after a major update, you'll reset your suction power preferences or your cleaning schedule, and you'll also want to start a quick cleaning operation to allow the device to calibrate the new motion algorithms.

Version comparison: what the developers have added

Understanding the differences between software versions helps to assess the need for updates. Often users ignore updates as meaningless until they encounter a critical vulnerability or incompatibility. The table below shows a comparison of conditional versions, demonstrating the evolution of Xiaomi robot software.

Importantly, moving to a new version can change the management interface within the application, some buttons can be moved, and virtual wall settings can become more flexible, for example, new firmware has the ability to sequence the cleaning of rooms, which was not in the earlier versions, allowing you to first vacuum the living room, and then move to the kitchen, which is more logical from a hygiene perspective.

Also worth mentioning are regional features: Global firmware (Global) versions are often released later than Chinese ones, but they are fully localized and certified to work in our region. Chinese versions may have richer functionality, but sometimes suffer from problems connecting to European servers. When upgrading, always check if the region of the device changes so you don’t lose control.

Typical problems and methods of their solution

Despite the fact that the process is fine, sometimes there are failures, and the most common problem is a server connection error, which can be caused by the locking of Xiaomi servers by the provider or temporary technical work on the manufacturer's side, in which case the change of the server helps. DNS-servers in router settings to public (for example, Google) DNS 8.8.8.8 or Cloudflare 1.1.1.1).

Another common situation is that the robot has upgraded but stopped seeing the map, which happens if the map file structure changes in the new firmware, the solution is to remove the old map in the application and build a new one from scratch. Don't be afraid of this process: with the new algorithms, it will take no more than 15-20 minutes and provide more accurate navigation in the future.

• 🔌 Unable to connect error: Check Wi-Fi password and frequency range (2.4 GHz only).
• 📉 Slow loading: Make sure the phone is not on VPN, which can block local devices.
• 🤖 Robot buzzes after update: Calibrate the gyroscope through an engineering menu or service reset.

⚠️ Attention: If after the upgrade, the robot starts to move randomly or crash into walls, don't panic. It could be the process of adapting the lidar. 2-3 If the problem persists, reset to factory settings.

💡

If the update fails several times in a row, try handing out Wi-Fi from your mobile phone (with a network name and password like your home router) so that the robot “pushes” the update via the mobile Internet, and then return it to the home network.

Reset and return to factory settings

In some cases, the update may not be correct, making errors in the configuration files. If the robot is behaving strangely, the best solution is a full reset, which will return the device to the “out of the box” state by removing all maps, schedules and Wi-Fi settings. This is a necessary step before selling the device or transferring it to another user.

To perform reset on most Xiaomi and Roborock models, you need to simultaneously clamping two buttons (usually Home and Turn on) or hold the reset button on the bottom panel for 5-10 seconds until the characteristic audible signal.

Once reset, you need to reconnect your device to your Wi-Fi network. Importantly, if you have changed the region in the application, make sure that it matches the region for which the firmware was designed. Mixing regions (for example, the device is for China, and the account in the application is Russia) can lead to the inability to update in the future or limit functionality.

💡

A complete reset is a radical, but often the only way to fix software errors that occur after a failed update or system failure.

Remember, once reset, all previously stored maps of the premises will be deleted. You will have to re-clean the entire room so that the robot can build the map. However, as practice shows, the new card, built on fresh firmware, works more stable and more accurate than the updated old one.
