Modern cleaning devices have long since ceased to be mechanical assistants, becoming full members of the smart home ecosystem. However, when you first launch, many users face an unpleasant surprise: the robot begins to speak Chinese or English, which creates some discomfort during operation. The question of how to change the voiceover to a Xiaomi robot vacuum cleaner becomes relevant immediately after unpacking a new gadget.
The process of localizing the voice interface depends on the model of your device, the installed version of the firmware and, most importantly, the selected region in the application. In some cases, it is enough to simply switch the country in the account settings, and in others you will need to manually install the language package through an engineering menu or third-party utilities. Understanding the architecture of the Mi Home will help avoid unnecessary errors.
In this detailed guide, we’ll look at all the known ways to change language, from official methods to advanced techniques for power users, learn why the robot is silent or speaking the wrong language, how to properly tie the device to the right server, and what are the nuances for the Roborock, Dreame, and Vacuum models. Follow the instructions carefully to ensure that your assistant speaks in a language you understand.
⚠️ Warning: Before any manipulation of regional settings, make sure you remember the password from your Mi Account.Region change may require re-authorization, and loss of account access will block device management.
Why does a robot vacuum cleaner speak a foreign language?
The main reason your robot vacuum cleaner is broadcasting in Chinese or English is because of the logic of Xiaomi cloud services: Voice packets are not stored in the memory of the device itself, but are loaded dynamically from servers depending on which region is selected in the Mi Home application. If you bought a device designed for the domestic market of China (Global version or CN version), when linked to a Chinese server, it will automatically pull up the corresponding language package.
Often users make the mistake of choosing the "China" region when adding a device because that's where it's in the database and forget to switch back. As a result, the voice engine stays (locked) in the anchor region language. It's also worth considering that some models released exclusively for the Asian market may not have official support for Russian or European English in the firmware by default.
There is also a problem of compatibility of the application versions. Older versions of Mi Home may not have handled language change requests for new models of vacuum cleaners correctly. So before you start setting up, it is critical to update the application to the latest available version in the App Store or Google Play. Only the current software contains the necessary scripts for managing language resources.
The official method of changing the language through the Mi Home app
The easiest and safest way to change voiceovers is for most global models officially shipped to your region. The action algorithm is built around changing the region in your user profile. First, open the Mi Home app and go to profile by clicking on the Profile tab in the lower right corner. Then select Settings (usually the gear icon) and find the Region line.
Once you change region, the app will reboot and you will need to log in again, and if your device supports the selected region, it will automatically pull the desired language packet the next time you connect to Wi-Fi. However, if the robot was tied to a Chinese server, simply changing the region in the phone settings may not work — the device is "tied" to the server of its first registration.
In this case, you need a procedure for unbundling and re-binding. Remove the vacuum cleaner from the list of devices, click on the plus-plus to add a new gadget and make sure that the application selects the region you want (for example, Russia or Germany).
☑️ Checklist before changing the region
It is important to understand that changing the region in the application does not always lead to an instant change in voice. Sometimes you need to completely reset the network settings on the vacuum cleaner itself. This usually requires you to press the on and back button (or spot clean button) for 5-10 seconds at the same time until the device reports a Wi-Fi reset.
Configure voice packs for Roborock and Dreame models
Sub-brands like Roborock and Dreame often have their own apps (Roborock, Dreame Home) but also support Mi Home integration. In their own apps, the logic of changing the language may differ. In Roborock, for example, the voice packet is tied to the interface language of the app itself. If you want Russian voiceover, the application interface must also be in Russian.
The situation is similar for Dreame models, but there is often a problem where Russian is only available when linked to the Russia or CIS region. If the device is global but has been activated in China, the language change via settings may not be available, in which case the temporary change of region in the Dreame Home app to Russia helps, after which the voice notification menu will be able to download Russian.
| Model/Brand | Required annex | Region for RU language | Features |
|---|---|---|---|
| Xiaomi Vacuum | Mi Home | Russia/China | Depends on the firmware version. |
| Roborock S5/S6/S7 | Roborock / Mi Home | Any (depending on app language) | Voice = Interface language |
| Dreame D9/V10 | Dreame Home / Mi Home | Russia/CIS | Package loading required |
| Viomi | Viomi Home / Mi Home | China (often) | Complex localization |
It's worth noting that some advanced models allow you to choose the voice of the announcer (male or female) and even the speed of speech. These settings are usually located in the Settings section → Voice Package. If you don't see these options, your version of firmware may be outdated and needs an update.
Use of voice packets and third-party solutions
For enthusiasts and owners of Chinese firmware (CN Version), there are methods for installing custom voice packets, thanks to the open Android architecture that many smart vacuum cleaners are based on. One popular way is to use the MIJIA Localtuya utility or access the file system via ADB (Android Debug Bridge) if the model allows debugging.
The process is as follows: the user downloads a voice packet file (usually.pkg or.bin files) from trusted sources, such as the 4PDA forum or the GitHub community repository. The file is then uploaded to the device’s root folder or special directory /mnt/UDisk/voice. After the reboot, the robot must pick up a new file.
However, this method has risks: an incorrectly selected voice packet can cause the robot to stop making any sounds or go into a cyclical reboot, and installing unofficial software can disrupt navigation algorithms, since the voice engine is closely integrated with system processes.
⚠️ Note: Installation of third-party voice packets through ADB or Telnet cancels the manufacturer's official warranty, and use this method only if you are confident in your actions and understand the risks of "bricking" the device.
There are also special scripts for Home Assistant that allow you to completely disable the built-in voice of the robot and use the speech synthesis of your smart home for announcements.This requires a separate Home Assistant server and customized integration with the vacuum cleaner, but gives maximum flexibility in setting up notifications.
Problems with connecting and updating firmware
Often, the inability to change the language is due to the banal lack of firmware updates. Manufacturers regularly release patches that add support for new languages. To check for updates, go to the device card in the Mi Home app, click on the three dots in the upper right corner and select Update Checker.
If the update doesn't install, check the battery power. To start the process, the charge should be at least 20%, or better be connected to the base. Also make sure that the robot is in the zone of reliable Wi-Fi reception. Interrupting the voice packet load can damage system files.
In some cases, cleaning the app cache helps. For this, on Android, go to Settings → Apps → Mi Home → Memory → Clear the cache. On iOS, you will need to reinstall the application. After this, try checking for voice packets again.
If the robot has updated but the language hasn't changed, try to force a voice test. The voice settings menu often has a "Listen" or "Test" button, and clicking on it causes the device to request the current audio file from the server, ignoring the cached version.
