Owners of Xiaomi smart devices often face a funny but sometimes annoying situation: a robot vacuum cleaner begins to actively comment on its actions, but it is impossible to understand it. Instead of the usual Russian language, “Start cleaning” or “Go back to base”, a stream of unfamiliar sounds from the speakers that resemble Chinese speech or a set of numbers is heard, this is because many models, especially versions for the global market (Global) or brought from China (CN Version), have pre-installed language packages that do not always coincide with the region of use.
Understanding what your machine is saying is critical to diagnosing problems. Voice messages are the main way the device communicates with the user, except for flashing indicators. If the robot persistently repeats the same phrase, it signals a specific malfunction that can be fixed without calling the wizard. Ignoring these audible signals can cause the turbobrush to break or the battery to fail.
In this article, we’ll look at how to get your assistant to speak in a clear language, how to change the volume, and what the most common phrases mean. You’ll learn why some models may “silence” or make strange sounds, and how to scroll through the official Mi Home app. Customizing audio is the first step to a comfortable interaction with smart appliances in your home.
Why does the vacuum cleaner speak Chinese or English?
The main reason for the language discrepancy lies in the firmware version and the region chosen when you initially set up the device. Global versions of robot vacuum cleaners often come with multilingual support, but by default can activate English or Chinese depending on the server the device is connected to. If you bought a device on a Chinese site without a Global Version mark, the probability that it will broadcast on mandarín is 99%.
Older devices, such as the first versions of the Xiaomi Vacuum 1 or Roborock S5, have hard-stitched language packages that depend on the regional version of firmware. However, modern models, including the Xiaomi Robot Vacuum E10 and Roborock S7, allow you to change voice support programmatically through the app, this is done for the convenience of users who may want to teach children a foreign language or just diversify cleaning.
⚠️ Warning: Forced region change in Mi Home’s language change application may result in loss of warranty and inability to manage the device due to server locks.
Also, it’s worth considering that some “smart” features, such as obstacle recognition or mapping, may require a specific language to properly operate voice control if you’re using integration with voice assistants. If a robot says incomprehensible phrases, it may mean that it is trying to count. QR-code from a charging station or reports low Wi-Fi signal.
How to Change the Language of Voice Commands in the Mi Home App
The language change procedure varies depending on the vacuum cleaner model and the version of the Mi Home (or Xiaomi Home) app. For most modern devices, you need to go to the device card, click on the three dots in the upper right corner to enter the additional settings, and find the Voice Control or Voice Pack item.
If you don't have Russian in the list of available languages, you can often add it manually by downloading a special package. Official support for Russian is not available in all regions of the account. Sometimes it helps to temporarily change the region in the Mi Account profile settings to "Russia" or "China", after which the necessary options appear in the voice packets menu. After downloading the package, you need to restart the device to apply changes.
☑️ Language change algorithm
If the process is interrupted, the robot can return to default or stop making sounds at all. In some cases, especially with Chinese versions, it requires the use of third-party utilities or modified versions of applications, which carries risks to data security, but allows you to install any language, including synthesized speech.
What if the Russian language is not on the list?
Decoding of major voice messages and error codes
Even without knowing the language, you can understand the state of the device by the intonation and repeatability of phrases. However, accurate diagnosis is possible only with knowledge of the translation. Xiaomi robots use standardized voice messages that correspond to certain error codes displayed in the application. Below is a table matching typical situations and what the device usually says.
| Situation | Typical phrase (RU) | Typical phrase (EN/CN) | User action |
|---|---|---|---|
| Start of work | "I'm starting cleaning up." | «Starting cleaning» / «Kai Shi Qing Sao» | Nothing, there's a full-time job. |
| The wheel problem | Help me, the main wheel is stuck. | «Please help me, main wheel stuck» | Check the wheels on the hair coil |
| Low charge. | "Low charge, back to base" | «Low battery, returning to dock» | Make sure the database is on the network |
| Sensor error | "Please wipe the sensor." | «Please clean cliff sensor» | Wipe the drop sensors with dry cloth |
Special attention should be paid to reports of getting stuck. If the robot repeats the phrase about getting stuck, but is visually free to move, the problem may be in the bumper sensors or wheelbase. In such cases, voice alert is the first indicator of mechanical failure, ignoring these signals leads to increased wear and tear of the motor wheels.
There are also specific service-related messages, such as a reminder to clean the HEPA filter or replace the side brush. These phrases are programmed based on the motorcycle clock counter and can sound annoying if the filter has been cleaned but the meter has not been reset. Timers are usually reset via an app in the service section.
💡
If the robot says it's stuck, flip it over and check if the wheels are rotating freely with your hand. Often, the pile or threads block the rotation sensor, making the system think the wheel is locked.
Setting volume and turning off voice
Many users prefer silence during cleaning, especially if the robot works at night or when children are sleeping in the room. Fortunately, most Xiaomi models allow you to adjust the volume of the speaker or completely turn off voice support, this is done either through physical buttons on the body (a combination of buttons) or through a software menu.
In the Mi Home app, you need to find the device settings and the slider "Volume" or "Loudness." Moving the slider to the far left position is usually equated with "No Sound" (Mute) mode. On some models, such as the Xiaomi Vacuum Mop 2, you can choose "Quiet" mode, where the robot emits only short audio signals instead of full phrases.
- 🔇 Full shutdown: Voice messages are not played at all, only light indicators are working.
- 🔉 Quiet mode: Volume down, phrases reduced to a minimum.
- 🔊 Standard Mode: Full Volume and All Notifications Enabled.
It's worth noting that even when the voice is turned off, critical errors (such as a fire in the engine or a fall from a height) can be accompanied by an emergency beep that cannot be turned off software. This is a safety measure provided by the manufacturer. If you want complete silence, make sure that the robot is operating normally without errors.
Why does the vacuum cleaner keep silent or make strange noises?
The situation where the robot stops talking can be caused by several factors: the most common is that the Do Not Disturb mode (DND) is activated in the schedule or settings. In this time interval, the device does the cleaning, but blocks all the audible notifications. Check the DND settings in the application, perhaps the current time falls into this range.
Another is software failure or damage to the audio file: If the robot makes distorted sounds, cracks or hums instead of speech, maybe the speaker is damaged or the plume has gone away, in rare cases, a complete reset of the device to factory settings (Reset), which is usually done by long-term pressing of the on button and the home button.
⚠️ Note: If after resetting the settings and reconnecting to Wi-Fi, the robot is still silent or emits an intermittent squeak, this may indicate a hardware malfunction of the speaker or motherboard.
And it's not the speakers that make strange noises, it's the mechanical parts that make strange noises. A high whistle can mean that the air duct is clogging or the bearings of the turbine are wearing out. A robot can growl or hum if the hair is wound in the main brush and the motor is overloaded. Listen carefully to the sound source: if it's coming from the bottom of the control buttons, it's a mechanical problem.
💡
Lack of voice during normal operation is often a sign of DND mode, but intermittent squeak or crackling requires immediate diagnosis of mechanical nodes.
Integration with voice assistants and smart home
Xiaomi’s modern vacuum cleaners are perfectly integrated into the smart home ecosystem, and you can control them not only through the app, but also through your voice, using Yandex.Alice, Google Assistant or Siri (via HomeKit), in which case the robot itself can be silent, and your smart speaker will give you the cleaning status and answers to questions.
To set up the integration, you need to link your Mi Home account to the appropriate smart home service, and then you can see scripts like "Alice, start cleaning the kitchen" or "Siri, how long did the vacuum cleaner work?" This allows you to use Russian to control even models that speak only Chinese themselves.
Using external assistants also allows you to create complex scenarios, such as when you say "I'm gone," the robot can automatically start cleaning, and the smart lock can close, and voice messages from the vacuum cleaner itself in these scenarios are often turned off so as not to create a noise background, relying on notifications in the smartphone.
