Smart homeowners often face a pleasant but frustrating surprise: the device works fine, but the app interface is entirely or partially in Chinese, and this is true for Xiaomi robot vacuum cleaners and sub-brands like Dreame or Roborock. Changing the region in the app is not just a cosmetic procedure, it is the key to full functionality, voice packages and correct card performance.
Many users mistakenly believe that changing the language requires disassembling the device and soldering memory chips. In fact, 95% of the time, software manipulation via an Android smartphone is enough. The process is often called “firmware,” although technically it is a change in the anchor server or update regional software. It is important to understand that regional binding determines which language the device will “communicate” with you and what features will be available.
Before you start taking action, you need to make sure that your vacuum cleaner is compatible with global servers. Most models shipped officially or through large marketplaces have an international version of the firmware hidden behind the Chinese interface. However, there are models that are tailored exclusively for the domestic market of China, which may require a more complex procedure or install a third-party firmware.
Preparation of the device and smartphone for flashing
The success of the operation depends on eighty percent proper preparation. Don’t ignore this stage, as an interruption of the process or an unstable connection can lead to the vacuum cleaner being “stuck” in standby mode or lose communication with the router. First of all, make sure that your Android device has the latest version of the Mi Home or Xiaomi Home app installed.
The second critical point is the stability of the Wi-Fi network. Xiaomi vacuum cleaners work exclusively in the 2.4 GHz band. If your router broadcasts a 5 GHz network of the same name (SSID), this can cause a conflict when connecting. It is recommended to temporarily divide the networks in the router settings or disable 5 GHz during the procedure.
⚠️ Before you start any manipulations, make sure that the vacuum cleaner battery is charged at least 60%. If during the process of updating the region or firmware, the device turns off due to the battery discharge, it will be extremely difficult or impossible to restore its operability without special equipment (programmer.
You also need to check your account location. The profile settings often include China, which is automatically offered by Chinese servers. To work with Russian, you may need to create a new account or change the region in the application settings, but simply changing the region in the profile is often not enough for already attached devices.
Change of region in the Mi Home app
The easiest and safest way to flash the language is to link the device to the right server, and the logic of the Xiaomi ecosystem is that the interface language of the vacuum cleaner and voice packets depends on which region the device is tied to when it is first added.
If you have already tied the vacuum cleaner to a Chinese server, you will have to remove the device from the list. Find your robot icon, go to the settings (three dots in the corner) and select Delete the device. Then in the user profile (Profile section), change the region to "Russia" or "Germany" (European servers often have a more complete translation than Russian).
When you change region, the app will reboot and the list of devices will be empty. Now you need to put the vacuum cleaner in pairing mode. Usually, you need to simultaneously press the Home button and Spot Cleaning buttons on the case until you have a voice message or flash the Wi-Fi indicator. In the application, click Add Device, and the system should find your device.
☑️ Checklist before re-tipping
During the setup process, the app will prompt you to select a Wi-Fi network. Make sure the phone is connected to exactly 2.4 GHz. If automatic detection fails, use manual add mode via QR-code-in IP. After successful connection, the control interface, map and settings menu should be displayed in Russian.
💡
Changing the region of the account before the device is tied is the only legal way to get Russian without flashing the internal software.
Instructions for changing the voice packet
It is often the case that the text interface in the application is already in Russian, but the vacuum cleaner itself continues to speak Chinese or English, which means that the device has a local voice packet, and you can fix this directly through the application menu without resorting to complex technical methods.
Go to the robot control, click on the three dots in the upper right corner, and select Voice Package, which will show the list of available languages, and if the language you want isn't on the list, click Download More or Online Voice Packages.
In the list that opens, look for "Russian" or "Russian." Click on the download icon. After downloading, click Set. The vacuum cleaner will reload the audio module and confirm the change of language with a phrase in Russian. If the list is empty or the button is inactive, then the current account region does not support downloading packages for this model.
| Model vacuum cleaner | Support for language change | Need for flashing | Region for RU language |
|---|---|---|---|
| Xiaomi Vacuum 1S | Complete. | No. | Russia / Europe |
| Roborock S5 Max | Complete. | No. | Russia / Europe |
| Dreame F9 | Partial | Maybe. | Europe |
| Xiaomi E10 (China) | Limited. | Yeah (difficult) | Only China. |
It is worth noting that some models, especially those exclusively for the domestic Chinese market (often labeled CN Version on the box), may not have Russian voice packs in the official repository, and in such cases, users resort to installing modified firmware, but this requires advanced skills.
Update and reset to factory settings
If the region change didn't help, you may have an outdated version of the microcode that doesn't work with the new language packs. Go to the device settings in the Mi Home app and find Update Check.
If you have a new version of firmware, the system will suggest installing it, and during the upgrade process, the vacuum cleaner can restart several times, emit beeps and flash indicators, and it is strictly forbidden to turn off the robot or close the application at this time.
⚠️ Warning: If the vacuum cleaner lights up orange during the software update and the device stops responding to commands, don't panic. 30-40 Often the system recovers on its own after a failed recording attempt.
If the language hasn't changed after the update, do a full reset. Most models have a small hole on their body that says Reset. Press it with a paper clip and hold it for 5-10 seconds until the characteristic beep. After the reset, try adding the device again, changing the region of the account beforehand.

Solving Connection Problems
The process of “firmware” language through a server change does not always go smoothly: users often encounter an error “failed to connect to the device” or “timeout connection”, this can be due to the blocking of ports by the provider or the settings of the router.
Try to turn off mobile internet (3G/4G/5G) on your phone during setup. Android sometimes tries to use the mobile network to check the internet connection, ignoring Wi-Fi, which confuses the process of handing over credentials to the vacuum cleaner. Leave only Wi-Fi and Bluetooth on.
Another common problem is using special characters in your Wi-Fi password. If your password has characters like #, & or spaces, some older versions of vacuum cleaners may not handle them properly. Temporarily change your password to a simpler one (just letters and numbers), link the device, and then return the complex password to the router.
- 📱 Make sure that the Mi Home app is given all the necessary permissions, especially access to geolocation and Bluetooth.
- 📡 The distance between the router and vacuum cleaner should be minimal when setting up (1-2 square).
- 🔄 Try using a Hotspot from another phone, naming the network just like your home and entering the same password.
Alternative methods and modified firmware
For advanced users who don't like the official methods, there's a way to install custom software. One of the most famous projects is VacuumZ, or using local management utilities, which not only allow you to change the language, but also access hidden features such as adjusting the power of suction outside of presets or managing through Home Assistant.
However, it is worth remembering that installing third-party firmware (Custom Firmware) almost always deprives the device of warranty, and there is a risk of turning a smart gadget into a “brick” if the version of the software does not fully comply with the hardware revision of the board.
💡
There is a separate Valetudo app for Roborock models that allows for fully autonomous work without Xiaomi’s cloud, but installing it requires Linux and SSH command line skills.
If you do, look for instructions specifically for your model in specialized forums such as 4PDA or GitHub developer repositories. The common algorithm usually involves root access through vulnerabilities in older versions of software, installing an ssh server, and uploading new language files to the /mnt/UDISK/voice system folder.
