Can I put a mate in the voice of the vacuum cleaner Xiaomi: technical tricks and consequences

Owners of Xiaomi robot vacuum cleaners often face a desire to personalize the device, from changing the standard voice to a more pleasant one to radical experiments like installing obscene language, the latter are especially popular among users who want to surprise friends or add a “highlight” to their daily cleaning. But replacing voice with a mate is not just a fun thing, but an interference with the system files of the device with consequences.

In this article, we will look at all the possible ways to change the voice of the assistant in the vacuum cleaners Xiaomi Mi Robot, Dreame and Viomi — from official alternatives to hacks with firmware. You will learn what models support customization, how to circumvent manufacturer restrictions and what to do if after experiments vacuum cleaner stopped working. Importantly, none of these methods guarantee 100% success — the risk of “bricking” the device remains always.

Why Standard Voices Are Irritating: Psychology and Technical Limitations

Xiaomi’s voice assistant vacuum cleaners are not just voiceovers, but part of its MiHome or DreameHome software. The manufacturer uses standard voices from Baidu or iFlytek that many find too monotonous or even “irritating.” According to a 2023 survey of smart tech owners, 42% of respondents would like to change the robot’s voice, and 18% would like to replace it with something “extreme,” including a mate.

There are some reasons why Xiaomi doesn’t change its voice:

• 🔒 License Restrictions – Votes are purchased from third-party providers and their modification violates the Terms of Use.
• 🛡️ Hacking protection – open access to system files increases the risk of installing malware.
• 🌍 Localization – different countries have censorship laws (for example, in China, a mate in the voice of the device will lead to a blockage of the model).
• 🔧 Technical complexity – voice packets are integrated into firmware and are not intended to replace.

But, enthusiasts have found workarounds, but before you start experimenting, consider the risks:

⚠️ Warning: Replacing system audio files can result in loss of warranty, unstable vacuum cleaner operation (hangs, navigation errors) or complete device failure.Recovery after "bricking" often requires a soldering iron and a programmer.

What Xiaomi models support voice change (officially and unofficially)

Not all Xiaomi vacuum cleaners allow you to change your voice, depending on the model and version of the firmware. Below is a table with the current data for 2026:

If your model doesn’t make it to the table, check it out on forums like 4PDA or Reddit. For example, for vacuum cleaners based on the MT7688 chip (for example, Viomi SE), there are universal methods through SSH.

Method 1: Official voice replacement (for supported models)

If you are lucky enough to have your vacuum cleaner support changing your voice out of the box, it will take no more than 5 minutes, for example, in Dreame Bot L10 Pro and Z10 Pro, this is done through the DreameHome app:

1. Open the app and select your vacuum cleaner.
2. Go to Settings → Voice prompts.
3. Choose one of the available voices (usually male/female in Chinese or English).
4. Save the changes and restart the vacuum cleaner.

Unfortunately, there are no hard versions in official firmware. The best you can do is:

• 🎤 Record your voice and upload it via Mi Home (available only in some regions, such as China).
• 🔄 Use third-party apps like Yandex Alice or Google Assistant to manage vacuum cleaners with custom voice responses.

⚠️ Note: In the Russian version of Mi Home, the user vote upload function is disabled due to legal restrictions (FZ “On Protection of Children from Information”). Bypassing is possible through changing the account region to Chinese, but this violates the user agreement.

Method 2: Replace audio files via ADB (for advanced users)

This method is suitable for vacuum cleaners based on Android (for example, Dreame Bot L10 Pro or Mi Robot Vacuum-Mop 2 Pro).The essence of the method is to connect to the device using ADB (Android Debug Bridge) and replace the standard sound files.wav or.mp3 on your own.

• 🖥️ Computer with Windows/Linux/macOS.
• 🔌 USB-cable (usually Micro-USB or Type-C).
• 🛠️ Utilities: ADB, Fastboot, HxD or Audacity Editor.
• 🔊 Ready sound files with mat (you can write yourself or download from forums).

Step-by-step:

Enable the developer mode on the vacuum cleaner (5 times click on the software version in the settings)

Connect the vacuum cleaner to the PC and allow debugging over USB

Download and unpack ADB Tools (e.g. from Google)

Get root access (some models require unlocking the bootloader)

Create a backup of original audio files-->

1. Activate Developer Mode: Go to Settings → About Device and 5 times click on Build Number. Return to the main settings and the Developer Item will appear.
2. Connect the vacuum cleaner to your PC: Use the original cable. In the developer settings, enable USB debugging and confirm your trust in the computer.
3. Get root access: You need to unlock the bootloader (instructions are available on XDA Developers). For example, for Dreame Bot L10 Pro, the command is used: fastboot oem unlock
4. Find audio files: Through ADB Shell, run: adb shell find /system -name ".wav" -o -name ".mp3" Usually files are in /system/media/audio/ or /vendor/tts/.
5. Replace your files: Copy your files (for example, start_cleaning.wav It's the same folder, replacing the originals!
6. Reboot the vacuum cleaner: adb reboot

If after replacement the vacuum cleaner gives an error or does not turn on, return the original files from the backup.

💡

To make the mat sound natural, write down phrases with the same intonation as the original voice. Use Audacity to normalize volume and remove noise.

Method 3: Firmware custom software (Valetudo, OpenMiHome)

For the bravest, installing alternative firmware, like Valetudo, is open source software that completely replaces Xiaomi's standard firmware and allows you to customize everything, including voice prompts, but the process is complex and only suitable for advanced users.

Pros:

• ✅ Full control of the device (you can remove cloud binding to Mi Home).
• ✅ Support for user sounds and voice.
• ✅ No restrictions on the region.

Cons:

• ❌ Complex installation (a soldering iron is required to connect to the UART).
• ❌ Loss of warranty and risk of “bricking».
• ❌ Not all functions can work (e.g., laser navigation).

Instructions for installation of Valetudo:

1. Download the firmware from the official website.
2. Connect to the vacuum cleaner via UART (you need to open the case and solder to the contacts).
3. Download the firmware via TFTP or SCP.
4. Set up the Valetudo web interface and upload your audio files.

⚠️ Note: Valetudo's firmware removes all data from the vacuum cleaner, including maps of the premises!

Method 4: Hardware hacking (for extremes)

If the software methods don't work, there's a physical intervention, which is to connect an external audio playback module, which is used in car radio moding, and is suitable for vacuum cleaners with a speaker connector.

You'll need:

• 🔊 DFPlayer Mini module (about 300 rubles).
• 🔋 Power supply (can be taken from the vacuum cleaner board).
• 🎤 MicroSD card with recorded phrases.
• 🔧 Stove iron and wires.

Algorithm of action:

1. Disassemble the vacuum cleaner and find the speaker (usually located next to the power button).
2. Unplug the wires from the speaker and connect them to the DFPlayer Mini.
3. Write sound files on the MicroSD card in format MP3 (for example, 001_start.mp3, 002_error.mp3).
4. Connect the module to the power (you can take 5V from the control board).
5. Get the body together and check the work.

The advantage of the method is 100% customization (you can put any sound, including mat, music or memes).

• ❌ Difficulty (needs ration skills).
• ❌ Risk of damaging the fee.
• ❌ Loss of original sounds (e.g. error warnings).

💡

Hardware hacking is the only way to put a mate on a model without USB-Ports (e.g. Xiaomi Mi Robot Vacuum) 1S).

Legal and ethical implications

Before installing a mate in a vacuum cleaner, consider the legal and social risks:

• 📜 Violation of the law: In Russia, the dissemination of obscene language in public places (for example, if the vacuum cleaner works in the office or entrance) can be qualified as petty hooliganism (Article 20.1 of the Administrative Code of the Russian Federation).
• 👨‍👩‍👧‍👦 Ethics: If there are children in the home, a mate in the device's voice can form negative speech habits.
• 🔧 Guarantee: Any interference with the software will void the warranty Xiaomi.
• 🌐 Cloud services: If the vacuum cleaner is tied to the Mi Home, modified sounds can be blocked by Xiaomi servers.

Alternative ideas for customization:

• 🤖 Putting Alice’s voice or SberSalute through smart home integration.
• 🎮 Replace the standard sounds with phrases from movies or games (e.g., “Cleaning complete» → «Mission accomplished»).
• 🎵 Use the vacuum cleaner as a Bluetooth speaker (some models support music playback).
