How to make the robot vacuum cleaner Xiaomi Mi Robot Vacuum-Mop swearing: full instruction with risks

Smart tech upgrades sometimes go beyond standard features. Xiaomi Mi Robot Vacuum-Mop owners often experiment with firmware, voice packs, and even unusual audio reactions, from funny phrases to... strong language. But before turning your cleaning assistant into a masculine Marine, it’s worth realizing: this is not just a “sound replacement,” but a deep interference with the device’s system files.

In this article, we will discuss three main methods of adding obscene voice responses to a robot vacuum cleaner: from the simplest (replacing standard sounds through Mi Home) to the extreme (reflashing with custom packets), you will learn which models support such manipulation, what tools will be needed, and why Xiaomi can lock your device after such experiments, and also legal alternatives for those who want to “voice” the vacuum cleaner without the risk of bricks.

⚠️ Warning: Modification of Xiaomi Mi Robot Vacuum-Mop system files violates warranty conditions and may result in complete loss of functionality of the device. In 2023, Xiaomi tightened control over custom firmware - some models (for example, for example, the company has been using the software for the first time, S10+ and later) are blocked when altered voice packets are detected.

What Xiaomi models support voice replacement?

Not all Xiaomi robot vacuum cleaners allow you to change audio files, and here are the key compatibility criteria:

🔹 Supported by Mi Robot Vacuum-Mop 1/1S/2/Pro, Mi Robot Vacuum-Mop 2 Lite, Mi Robot Vacuum-Mop P (pre-firmware version) 3.5.8_003024). These models use an open data exchange protocol and allow custom sounds to be uploaded via Mi Home. API.
🔸 Partially supported: Mi Robot Vacuum-Mop 2 Ultra, Xiaomi Robot Vacuum X10+ — require root access or special scripts to bypass protection.
🔶 Not supported: All models after 2023 (S10+, X20+ Xiaomi has closed access to system files through standard methods.

To find out the exact model and firmware version of your device:

Open the Mi Home app.
Go to the Devices. → Your robot vacuum cleaner → Settings (⚙️) → About the device.
Check the lines Model and firmware version.

⚠️ Note: If your model is released after September 2022, the chances of a successful modification without root rights are close to zero, in which case the only option is to use an external Bluetooth module to play sounds (more on this below).

Method 1: Replace standard sounds with Mi Home (the safest)

This is a good way to do it until 2022 and doesn’t require technical skills, such as replacing standard voice notifications (‘Start cleaning’, ‘Charging completed’) with your recordings, and negative: you can’t add dynamic responses (like a checkmate when you hit an obstacle).

What you need:

📱 Smartphone with Mi Home installed (version no lower than 6.5.400).
🎤 Pre-recorded audio files in format.mp3 (maximum duration - 5 seconds, bitrate - 128 kbit / s).
🌐 Sustainable Wi-Fi connection (robot and phone must be on the same network).

Step-by-step:

Download and install the Mi Home Modded app (modified version with advanced settings) on your smartphone. Link to the 4PDA theme.
Connect the robot vacuum cleaner to the application (if not already connected).
Go to Device Settings → Voice Packages → Download your sounds.
Download the prepared ones.mp3-files for each event (beginning of cleaning, completion, error, etc.).
Save the changes and restart the robot (reboot button in the settings).

⚠️ Note: When downloading files with obscene language, Mi Home may block your account for violating community rules. To avoid this, use encrypted audio files (for example, change playback speed to: 1.5x — Mat will become less discernible for moderation algorithms).

☑️ Preparation of sound files for Mi Home

Write down phrases ≤ 5 seconds longConvert to.mp3 (128 kbit/s)Delete metadata (via Audacity)Check the volume (not higher than -12 dB)Rename files in Latin (without spaces)

Done: 0 / 5

Method 2: Firmware custom voice package (for advanced)

If you want the robot to swear dynamically (like hitting a table leg or getting stuck), you’ll need to replace the system’s audio files, a method that only works on models with an unlocked bootloader and requires SSH connectivity.

Tools required:

🖥️ Computer with Windows/Linux and installed by Python 3.8+.
🔌 USB-to-TTL cable (to connect to the service port of the robot).
📦 Archive with custom firmware (for example, Valetudo) RE or DustBuilder).
🔑 Root access to the robot (instructions for obtaining below).

Step-by-step:

Unlock the bootloader: python mirobo.py --ip 192.168.1.100 --token YOUR_TOKEN unlock (where) YOUR_TOKEN — The device token can be obtained through the Mi Home Token Extractor).
Connect to SSH: ssh root@192.168.1.100 -p 22 The default password is 1234567890 (for old firmware) or rockrobo (for new ones).
Replace the sound files: cd /mnt/UDISK/miio/voice_pack/ mv original_voice.pack original_voice.pack.bak wget http://your-server/custom_voice.pack (where custom_voice.pack — your phrasing bag).
Reboot the robot: reboot

🔹 Where to get ready voice packets?

📌 GitHub: Roborock Voice Packs (Russian versions available).
📌 4PDA: Xiaomi Customization Topics (Search for Your Robot Model).

What happens if you interrupt the firmware?

If you turn off power or interrupt the process of replacing system files, the robot can: - Stop turning on (brick). - Obsess over the boot (endless rebuke). - Lose communication with Wi-Fi and require reset via the RESET button. Recovery is possible only through the service cable and the firmware of stock software.

Method 3: External Bluetooth module (for new models)

If your Xiaomi Mi Robot Vacuum-Mop is released after 2022, replacing the system sounds is almost impossible, but there is a workaround: plug in an external Bluetooth speaker and play mat through it at certain events.

How it works:

The robot sends notifications to Mi Home (e.g., “Stuck” or “Low Charge”).
A special script on a smartphone or Home Assistant catches these events and plays the sound through a Bluetooth speaker.

Equipment required:

🔊 Bluetooth speaker (e.g. Xiaomi Mi Portable Bluetooth Speaker).
📱 Smartphone with Tasker or Home Assistant on PC.
🔧 Automation setup knowledge (or ready profiles for Tasker).

Example of settings in Home Assistant:

automation:


- alias: "Robot stuck - mate in the column"




trigger:




platform: state




entity_id: vacuum.xiaomi_vacuum




to: "stuck"




action:




service: media_player.play_media




target:




entity_id: media_player.bluetooth_speaker




data:




media_content_id: "http://your-server/swear.mp3"




media_content_type: "audio/mp3"

⚠️ Note: The delay between the event and the sound playback may be 2-3 Also, keep in mind that if you're always connecting the speaker to the robot, it's draining the battery by a lot of time. 10-15% faster.

💡

To make the mat sound more realistic, write phrases with different intonations and use the ElevenLabs service to generate voices with emotions (anger, irritation).

Risks and Consequences: What Happens After the Modification?

Before turning your assistant into a Marine, assess the possible problems:

Type of risk	Effects of consequences	Probability.
Blocking of Mi Account	Banning the use of the Xiaomi ecosystem (including other devices)	High (if you download mat via Mi Home)
Loss of guarantee	Xiaomi will refuse to repair if custom files are detected	100%
Brick of the device	The robot will stop turning on after a failed firmware	Average (20-30%)
Problems with OTA-update	The device will not be able to update through official channels.	Tall.
Legal consequences	In some countries (e.g. Germany), modification of devices to spread obscene language may be considered a public order violation.	Low.

🔹 How to minimize risks?

🔧 Use the original firmware backup before any changes.
🔄 Test custom sounds on a secondary device (if any).
📡 Disconnect the robot from the Internet after the modification to avoid automatic updates.

💡

Even if the modification was successful, Xiaomi can remotely lock the device the next time it connects to the servers, and the only way to avoid this is to use Valetudo RE firmware, which completely cuts the robot off from the Xiaomi cloud.

Alternatives: how to "voice" a robot vacuum cleaner without risks?

If you just want the robot to “talk” more fun, but without the mat and complex modifications, there are legal ways:

🎤 Voice packs from the community: On 4PDA GitHub has hundreds of free packages with humorous phrases (for example, the voice of the Goblin or Darth Vader).
🤖 Integration with Alice/Google Adjust automation to allow the voice assistant to voice the robot’s actions (e.g., Alice, tell the vacuum cleaner to finish cleaning").
🎵 Music instead of voice notifications: In Mi Home, you can replace standard sounds with melodies (for example, "Imperial March" when cleaning starts).

🔹 Example of a legal voice package:

Download the archive with voices from here (example: Terminator Package), then upload it via Mi Home Modded as described in Method 1.

FAQ: Frequent questions about modifying voice packets

❓ Can I return the original sounds after the modification?

Yes, but the method depends on the method of change: If you used Method 1 (Mi Home), just download the standard voice packet back. If you were flashing files through Method 2, you will need to restore the backup or flash the stock firmware through fastboot. ⚠️ After restoring the original sounds, it is recommended to reset the robot to the factory settings (Settings) → Reset) to avoid conflicts with updates.

❓ Will voice commands work after the modification?

Most of the time, yes, but: If you used Valetudo RE, voice control will be turned off via Mi Home (this is cloudless firmware). When you replace sounds through Method 1, voice commands (such as "Alice, start cleaning") will continue to work.

❓ Can a robot be made to swear only at certain events (e.g., when a collision occurs)?

Yes, but for this you need: Use the method 2 (custom pack firmware) or Method 3 (External Bluetooth module: Manually link audio files to specific events in the robot's system configs (file) /mnt/UDISK/miio/voice_config.json). Example of a collision-binding config: {"events": {"bump": "collision.mp3", "stuck": "stuck.mp3" } }

❓ Is it legal to modify a robot vacuum cleaner in this way?

From a legal perspective: 📜 In Russia: the modification itself is not prohibited, but the dissemination of obscene language in public places can be qualified as "petty hooliganism" (Article 20.1 of the Administrative Code). 📜 In some countries (e.g. Germany), the use of devices with obscene voice packets in apartment buildings can be considered a violation of silence. 📜 Guarantee: Xiaomi has the right to refuse warranty repairs if custom files are detected.

❓ Where to download ready-made voice packets with mat?

🔴 Note: We do not distribute obscene content, but you can: Create your package with Audacity. + So, voice processing. Search forums like this. 4PDA (Use the search for "voice package mat Xiaomi"). Use the ElevenLabs neural network to generate voice with the desired intonation.
