The desire to personalize smart tech often leads enthusiasts to change the standard behavior of the device. Owners of Xiaomi Mi Robot Vacuum and its modifications often look for a way to make the gadget say unusual phrases or even grumble when cleaning, thanks to the open software architecture that allows you to embed custom audio packets and modify system files.
Changing the voice of a robot vacuum cleaner requires less programming knowledge than accuracy in working with the file system. Standard firmware contains a set of pre-installed audio files that can be replaced with custom recordings. However, it is worthwhile to understand that interference with system files always carries certain risks for the stability of the device.
Before you start making a modification, you need to make sure you're using a compatible version of the software. Different generations of robots, like the Xiaomi Vacuum Mop 2 or earlier Roborock S5 models, can have a great folder structure. It's also important to have a stable Wi-Fi connection to transfer the changed files to the device.
Preparation for software modification
The beginning of any serious firmware work is to assemble the tools you need: you need a computer running Windows, macOS or Linux, and access to a router that the robot is connected to. Without understanding the basics of network protocols and the Linux file system, the process can seem complicated.
The key is to gain access to the internal files of the device, and this is most often used file transfer protocol or special utilities for working with the device. ADB (Android Debug Bridge, if the model is built on Android. In the case of classic Xiaomi models, access is often via the Android platform. FTP-server built into firmware, or via Telnet.
⚠️ Warning: Before any manipulations begin, make sure to make a full backup of the original files. Factory settings recovery may not return remote system sounds.
Make sure your Xiaomi Robot Vacuum battery is at least 60 percent charged. Interrupting the file writing process due to battery drain can lead to a software failure that will require complex recovery through console commands. It is also recommended to disable automatic firmware updates in the Mi Home app so that the system does not update voice files while you are running.

Obtaining access rights to the file system
To replace audio files, you need to get superuser rights, known as root rights. Without them, the system will not allow you to change or delete files in the system directories where the audio assets are stored. Depending on the firmware version, the methods of accessing may differ.
One popular way is to exploit vulnerabilities in older versions of software or special scripts that run over a local network, and if your robot supports Developer Mode, turn it on in the application settings, which will open a debugging port through which you can send the necessary commands.
The activation process often looks like this:
- 🔧 Connect your computer and robot to the same Wi-Fi network.
- 💻 Determine. IP-address of your device via router or application.
- 🔓 Use specialized software to obtain access token.
- 📂 Enter the file system through FTP-client using the received token.
Once you log in successfully, you'll see a folder structure that looks like standard Linux, and we're interested in directories that contain media files, and be careful, removing excess system files can cause the robot to stop displaying statuses or responding to commands correctly.
Search and Replace Audio Files
The main task is to find the files responsible for voice support. In Xiaomi firmware, they usually have the.mp3 or.ogg extension and are located in folders with names like audio, sound or voice. Standard files often have numerical names, such as 1001.mp3, 1002.mp3.
To get the robot to start "spooking" or speaking in your voice, you need to replace these files with your recordings. It is important to follow the technical parameters: the audio format must be strictly MP3 with a bitrate of 128 kbps and a sampling rate of 44.1 kHz. Failure to comply with these parameters will lead to the robot either ignoring the file or playing distorted sound.
File compliance table
In some versions of the firmware file 1001.mp3 He said, "I'm starting the cleaning." 1005.mp3 — You're replacing them with "Finished cleaning." You're changing the context of events.> The process of replacing it is this: Copy the original files from robot to computer to save backup. Prepare your audio files by naming them exactly as the originals. Upload new files to the same directory on the device, agreeing to a replacement. Reboot the robot vacuum cleaner through an app or physical button. If the sound hasn't changed after the reboot, check the file access rights. They must match the rights of the original files (usually the right to access the file). 644). Also make sure that the file name does not contain Cyrillic characters or spaces if you create new files from scratch.Using third-party voice packets If creating your own records seems difficult, you can take advantage of ready-made solutions from the community. Enthusiasts create entire language packages, including comic and satirical voiceovers, often distributed as archives ready to be installed, and popular sources of modifications include dedicated forums and repositories on GitHub. When downloading, pay attention to the firmware version for which the package is created.Install sound from Xiaomi Vacuum Mop Essential on Xiaomi Vacuum S10 Packet type Compatibility Risk Error Difficulty Official language All models Low Minimum User MP3 Depending on version Medium Medium Modified firmware Specific model High High Valetudo Linux-based High Expert Installation of third-party packages often requires the use of a console. Example of a command to copy a file: cp /tmp/custom_voice.mp3 /usr/share/sounds/voice.mp3. An error in syntax can damage the file system. Installing an alternative firmware (Valetudo and others) For advanced users, there is the possibility of completely replacing the operating system with open counterparts such as Valetudo. This software completely disconnects the device from Xiaomi's cloud servers, transferring control to the local network. This gives you full control of the voice engine. TTS (Text-to-Speech engines or pre-built sound sets. You can set the robot to read news, report the weather, or comment on the amount of dust collected using a speech synthesizer. However, this method is only suitable for certain models with Realtek or Rockchip processors. ⚠️ Warning: Installing Valetudo custom firmware permanently disables the device from the official Mi Home app, you lose the warranty and the ability to use cloud features. The installation process involves flashing the bootloader, which is a critical operation. If the lights blink or the connection is interrupted, the device can turn into a brick, and recovery is possible only through disassembly and connection. UART-If you're doing this, look carefully at the Valetudo GitHub documentation for your particular model, which shows the exact steps, the files you need, and the known bugs. Don't try to install firmware from another model, even if they look the same. 💡Complete firmware replacement gives maximum flexibility, but requires deep technical knowledge and carries a high risk of device failure. In the process of modification, users often encounter typical errors: the robot may be silent, play a crack or give an error when starting, most often the problem lies in the wrong audio file format or incorrect access rights. Check the list of frequent problems: 🔇 No sound: The file has an incorrect bitrate or encoding format. 🤖 Robot does not move: damaged system file responsible for the logic of work. 🔄 Cyclical reboot: Firmware version conflict or bootloader damage. 📡 Wi-Fi disconnection: Network configs are broken. If the robot is no longer responding to commands, try resetting to factory settings. This usually requires you to simultaneously press the power and return buttons to base. 5-10 It'll bring back the standard audio files, but it'll delete your maps and settings. In the event of a major failure, when the device is not on or connected to the network, it may be necessary to flash through the engineering menu or UART. This is a complex process that requires a soldering iron and a USB-TTL adapter. Without experience in electronics, it is better to contact the service center. Frequently Asked Questions (FAQ) Can the robot be flashed without opening it? Yes, most models allow access to the file system through Wi-Fi and special utilities without requiring a physical disassembly of the case. However, for some new models, will the warranty fly out after replacing the sound center? Using verified packages from known developers is usually safe. However, files from unknown sources may contain malicious code or be incompatible, which will lead to failures. What if the robot stopped talking after replacing files? Check the audio format (should be MP3 128kbps) and access rights. If this did not help, restore the original files from the backup or reset the device to factory settings. Does Xiaomi officially support changing voice? No, the manufacturer does not provide official tools to replace system sounds with user ones. All methods are informal and are carried out by users at your own risk.
