How to Re-voice Xiaomi Vacuum Cleaner: The Complete Guide

Smart tech owners often face situations where their device’s standard voice pack doesn’t seem to be good enough or just doesn’t match their personal preferences. Robot vacuum cleaners like Xiaomi, Roborock and Viomi can default to reporting cleaning status in English or Chinese, which isn’t always convenient for the user. Replacing the voice packet makes interaction with the gadget more comfortable and understandable, especially if the standard voiceover sounds unnatural.

The process of changing the language or completely changing your voice depends on your device model and firmware version. In some cases, it is enough to simply change the region in the application, in others it will require a more complex procedure using third-party software. It is important to understand that modifying system files always carries certain risks, so you should carefully study the instructions for your particular model before starting any actions.

In this article, we will discuss all the available methods, from simple in-app settings to advanced methods through ADB. You will learn where to find quality Russian voiceovers, how to install them correctly and what to do if after updating the firmware voice again became Chinese.

Features of voice packets in the Xiaomi ecosystem

Xiaomi’s smart home ecosystem brings together dozens of manufacturers, including Dreame, Roborock, Viomi and 360, each with their own software architecture, which directly affects the ability to replace voice. Standard packages are often recorded by professional announcers, but the quality of speech synthesis can vary depending on the firmware version.

The main difficulty is that manufacturers often block the ability to install third-party files for the sake of system security. However, enthusiasts find workarounds. Voice packets are usually a set of audio files of a certain format that replace the system sounds of the device.

It's worth noting that some models only support switching between preset languages, while others allow custom files to be downloaded. Before you start, determine the exact model of your vacuum cleaner. This information can be found on the bottom of the device or in the Mi Home app in the settings section.

⚠️ Warning: Installing unverified voice packets from questionable sources can cause your device to run unstable or advertise. Use only files from trusted forums and from well-known developers.

Preparation for installation: tools and files

Before you start the modification, you need to prepare a work environment: you need a computer running Windows, macOS or Linux, as well as a stable Internet connection to download the necessary files. The main tool for working with the file system of Android devices is ADB (Android Debug Bridge).

To start, download and install drivers for your device if you need them. Then download the ADB platform tools from the official developer site. Unpack the archive into a convenient folder, such as C:\adb, so that the path does not contain Cyrillic or spaces, which can cause errors when executing commands.

You'll also need the voice file itself. It's usually an archive with a.zip extension, or a set of.ogg and.json files. Make sure the version of the voice packet matches the version of your vacuum cleaner's firmware. Version mismatches are the most common reason why the device refuses to play new sounds.

Remember to fully charge the robot vacuum cleaner before starting the procedure. The voice flashing process can take 5 to 15 minutes, and the power interruption at this point is critical. If the device turns off while recording system files, it may stop responding to commands.

Method 1: Change region in the Mi Home app

The easiest and safest way to change voice language is to change the region in the Mi Home app. Many users are unaware that country choices affect downloadable language packs. For example, choosing China region often gives access to a more complete set of voice commands, but in Chinese.

First, remove the device from the app. Then go to the profile and change the region to China or another region where you can find the voiceover you want. After that, add a vacuum cleaner. When you first set up the device, you can suggest that you choose the voice-over language.

But this method doesn't work on all models, because devices designed for the global market can ignore the region change or force the English packet to be loaded, and in such cases, more sophisticated methods are required.

💡

If the language hasn’t changed after the region change, try to completely remove the Mi Home app, clear its cache, and re-install it by selecting a new region when you first start.

Sometimes it helps to change the interface language of the smartphone itself, if the phone has Russian installed on its system, the app may try to tighten the appropriate package for connected devices, which works as an additional trigger for Xiaomi servers.

Method 2: Installation via local server and ADB

If standard methods don't work, you'll have to use a local server to swap voice files, and the idea is that we create a folder on the computer that the vacuum cleaner perceives as network storage, and we slip the files to it instead of the ones that it tries to download from the official server.

This will require you to set up a static IP-The address for your computer is on the same network as the vacuum cleaner, and then you create a folder structure that's identical to the system folder, and you copy the Russification files. ADB We tell the device to ignore official voice updates and use local voice updates.

Below is a table of matching popular models and paths to configuration files, which will help you structure folders correctly:

After you have prepared the files, you need to access the device via ADB. Enable debugging via USB (if there is a physical port) or use the application activation method (for some models).

adb connect 192.168.1.XX:5718

Where 192.168.1.XX — it IP-Once you've successfully connected, you can copy files with the adb push command. Be very careful when you type in the paths, an error in one character can result in the system not finding the file.

⚠️ Note: Do not copy files to system partitions unless you are sure of their purpose. Write only to custom partitions or use the swapping method through the system partition. DNS/server, if the model allows it.

Installation of custom firmware and voice packs

For advanced users, there is the possibility of installing modified firmware such as Valetudo or DustCloud, which completely frees the device from being tied to the Xiaomi cloud and allows you to control voice directly through the web interface.

The process of firmware is complicated and requires opening the case in some cases, you have to close certain contacts on the board to enter recovery mode, which voids the warranty and requires good electronics skills.

But if you do that, you'll have full control of the device, you'll be able to download any voice packets, even those recorded by your own voice, and the development community is constantly updating compatibility lists.

Once custom software is installed, the standard Mi Home app will stop seeing the vacuum cleaner, you will have to use alternative clients or a web interface, which is a trade-off between functionality and usability.

Typical problems and their solution

When you change your voice, you often have a lot of problems, and the most common one is that you can't see the voice files. Check the file names encoding, they have to be in the lower case, without spaces or special characters. Use only Latin.

Another problem is that the sound is there, but it's intermittent or distorted. This may indicate that the audio file bitrate is wrong. The standard for most devices is 16,000 Hz, mono,.ogg or.mp3 format. Convert the files to an audio editor before downloading.

If the vacuum cleaner is silent after all the manipulations or makes strange sounds, try resetting to the factory settings. Press the on and back button at the same time for 10-15 seconds. After resetting the voice installation procedure will have to be repeated.

💡

If the voice returned to factory after resetting, the installed firmware update automatically restored the original files, you will either need to block the update or reinstall the package after each update.

If you use an ADB method, make sure you have superuser rights (root) if the particular installation method requires it.
