Xiaomi Robot Vacuum Firmware: Changing Voice and Region

Many smart device owners face situations where the standard voice package of a robot vacuum cleaner is annoying or simply not meeting expectations. The Xiaomi Mi Robot Vacuum robot vacuum cleaner can by default speak too loud, monotonous or in a language you don't understand. Fortunately, the Android or Linux architecture on which the operating system of these devices is based allows for changes to the software.

The process of replacing firmware or modifying a voice packet is not just entertainment, but a way to expand the functionality of the device. You can make the vacuum cleaner swear, joke or just talk with a more pleasant timbre. However, before you start modifying the system, you need to understand that any interference with the code carries certain risks. Wrong actions can lead to your Xiaomi Vacuum becoming a “brick”.

In this article, we will discuss how to safely change voice messages, what tools will be required and why it is impossible to do this with standard methods. We will discuss the technical aspects of the robot file system and how to access it. Remember that software modification can void the warranty, so weigh the pros and cons before starting the procedure.

Anatomy of sound files in the Xiaomi system

To understand how to make a robot vacuum cleaner "fight" or change its speech, you need to understand where the sound data is stored. MP3-In Xiaomi Mi Robot, the sounds are packed into special archives or binary files, often with the.pkg extension or built directly into the system partition.

The robot's operating system, whether it's Vacuum Cleaner or newer models with MI Home, uses a directory structure. Audio files are usually located in directories like /opt/rockrobo/voicemap/ or /miio/voice/. This is where the packages responsible for the phrases "Dust removed," "Sensor error" and other notifications are located. Replacing these files allows you to embed any sound, including joke or satirical cues.

It is important to note that simply copy MP3-A file with a spelling in a folder will not work. The files must be recoded into a certain format (often OGG or PCM), It has a very specific name and bitrate, and if you break that, it's either going to keep silent or it's going to make a distorted squeak instead of a word.

⚠️ Warning: Direct editing of system files without backing up can cause the device to function unstable.Always save original files before replacing them.

There are two main ways to change voice: simple, through the installation of ready-made modified packages, and complex, involving manual assembly of a sound package. The first option is safer for beginners, the second gives full control over what your smart assistant will say.

Tools and environment preparation required

Before you start firmware or modification, you need to prepare the workplace. You need a computer with Windows, macOS or Linux. It is also critical to have a stable Wi-Fi connection and know the password from your network, as the robot will reconnect in the process.

The main tool for interacting with the robot’s file system is the Secure Shell (SSH) protocol, which requires a client program such as PuTTY for Windows or an embedded terminal in macOS/Linux to implement on a computer, and requires an SFTP-enabled file manager such as WinSCP or FileZilla to work with files.

You'll also need special tools to create audio packages. One of the most popular tools is the VacuumX project, or Python-based scripts, which allow you to convert regular audio files into a format that the robot can understand. Remember to download the original audio files of the model you have installed to use them as a template.

☑️ Preparation for modification

Done: 0 / 4

Make sure the device battery is at least 80% charged, or better fully charged. File writing and rebooting can take time, and a sudden power outage during operation can damage the file system. It is also recommended to disable automatic firmware updates in the MI Home app so that the system does not update the modified files back to standard ones.

Obtaining Superuser Rights (Root) via SSH

The most difficult step is to gain access to a system with superuser rights. In modern versions of Xiaomi firmware, SSH ports are closed by default, but for many models, such as the Roborock S50, S5 Max or Mi Robot 1S, there are exploits that allow you to activate access.

One of the common methods is to use a local token. You need to get your device's token from the app. MI Home (this can be done through an Android emulator or special extractor scripts). IP-The robot address and its token can be sent a special command that opens the port 22 for the robot to use. SSH-connection.

python -m miio.vacuum_cli --ip 192.168.1.XXX --token YOUR_TOKEN raw_command miio.debug_set_ip_info"{'ip':'192.168.1.XXX','port': 22}"

Once you have completed a command (or use pre-built utilities like miio or valetudo), you can connect to a robot. Standard access credentials are often root without a password or root with a password that depends on the firmware version. Old firmware is often a blank password, new ones require key generation.

What to do if the SSH is not connected?
If you're connected to SSH It's rejected, check if the firmware is automatically updated, and make sure you're on the same subnet as the robot, sometimes it helps to reboot the router and vacuum cleaner, and some models require a physical opening and connection. UART-It's a last resort, and once you get access, you become a full administrator, and you can see all the hidden folders and modify the contents, and that's where the magic of turning a useful assistant into a grumpy janitor comes in. Replacement of voice packet after successful connection SSH Opening access to files through SFTP, You start working directly with the sounds. Go to the directory where the voices are stored. /opt/rockrobo/voicemap/. You will see folders with language names, for example, ru, en, de. You have to choose a folder with Russian (or the one you want to replace) and you have files with names like this. charge_complete.ogg, box_full.ogg And so the strategy of the cursing robot is to replace those files with your own. You take a file, for example, box_full.ogg (The basket is full, and replace its contents with the phrase "Again you've messed up the floor, you're lazy: 🎙️ Format: OGG (often required to be converted to a specific bitrate, for example, 16000 Hz, mono). 📏 Size: The file must not exceed the original size if you replace it directly, or must be correctly spelled out in the config. 🔤 Name: The file name must be the same as the original, including the register of letters. 🔊 Loudness: Make sure your file is not quieter or louder than the original so as not to stun yourself or hear a whisper. After you change the files, you need to restart the audio service: /etc/init.d/rockrobo-voice restart, or simply restart the robot with the reboot command. ⚠️ Note: If the robot has stopped making sounds after replacing the files, the audio file format is incorrect. Return the original file from the backup. Comparison of modification methods There are several approaches to changing the voice, and the choice depends on your technical background. You can use ready-made modified firmware, you can edit files manually, or you can install alternative software. Consider the main differences between methods: Method Complexity Risk of loss of warranty Flexibility of settings Ready-made sound package Low Medium Low (only ready-made phrases) Manual replacement OGG Average High (any sounds) Valetudo Installation High Maximum (full flashing) Cloud hacks (Token hack) Average Medium (depending on the cloud) The most popular and safe method to start with is the manual replacement method OGG-file-based SSH. It doesn't require firmware to be completely reflashed, and it makes it easy to roll back changes. Install Valetudo is a way for advanced users who want to completely untie the robot from Xiaomi servers and get local management. Choose a method that suits your skills. If you are not confident in your abilities when working with the command line, it is better to limit yourself to finding ready-made modified packages on enthusiast forums. Problems and solutions: You may encounter a lot of difficulties in the process of modification, the robot may start to stutter, skip phrases, or even stop responding to commands, often due to incompatibility of the bitrate of the audio files.
