How to change the voice on the vacuum cleaner Xiaomi Roborock S6: all the ways

Why do Roborock S6 owners want to change their voice?

Voice alerts from the Xiaomi Roborock S6 robot vacuum cleaner are not just a nice bonus, but an important element of interaction. Standard voiceovers in Chinese or English can be annoying if you don't understand the phrases, or just get bored with time. Someone wants to hear their native Russian, someone needs a calmer intonation, and some users prefer to turn off voice prompts altogether to keep the vacuum cleaner quiet.

In this article, we will look at all the available ways to change voice to the Roborock S6, from official methods through the Mi Home app to hand-held firmware with custom voiceovers. We will also discuss the risks associated with informal changes and how to avoid typical mistakes. If you want your vacuum cleaner to “speak” differently, read on.

The Roborock S6 only supports voice change to a limited extent. Unlike newer models (like the S7 or S8), there is no built-in menu with a selection of languages. But there are workarounds, and we'll look at them.

Method 1: Change the language through Mi Home

The easiest and safest method is to change the language of the vacuum cleaner system through the Mi Home app, which will not give you a choice of dozens of votes, but will allow you to switch between the available languages (Chinese, English, sometimes Russian depending on the region).

Here's how to do it:

1. Open the Mi Home app and connect to the account to which the vacuum cleaner is tied.

Important: not all regions support Russian, if you have a Chinese or US presence on your account, you may not have the option.

• 🌍 Change the region in the Mi Home settings to “Russia” or “Europe” (in your account profile).
• 🔄 Restart the application after changing the region.
• 📱 Update the vacuum cleaner firmware – sometimes newer versions add language support.

If your voice hasn’t changed after changing your language, check:

• 🔌 Connecting the vacuum cleaner to Wi-Fi (without the Internet, changes will not apply).
• 📲 Mi Home version (upgrade to the latest in Google Play or App Store).
• 🔧 Version of the vacuum cleaner firmware (up-to-date — 3.5.8_003634 higher).

💡

If Mi Home doesn't have a language change option, try removing the vacuum cleaner from your account and adding it again, sometimes resetting regional restrictions.

Method 2: Manual update of firmware with custom voice

If there are few official languages, you can install informal firmware with alternative voiceovers, a method that is suitable for advanced users, as it requires working with files and potentially risks building up the device.

Here's what you're gonna need:

• 💻 Computer with Windows/macOS/Linux.
• 🔌 USB-Type C Cable (to connect vacuum cleaner to PC).
• 📁 Custom voice firmware (for example, from the Roborock Modders community).
• 🛠 A firmware tool – Roborock-Vacuum-Tool or Python microprogram.

Step-by-step:

Download the archive with firmware (check compatibility with S6)|

Install drivers for MediaTek (vacuum chipset)|

Connect the vacuum cleaner to your PC in ADB mode (press the Home + Power button for 10 seconds)|

Backup your current firmware (backup in Roborock-Vacuum-Tool)

-->

1. Download custom voice firmware. Popular sources: XDA Developers Forum (Roborock section), Roborock Modding Telegram channel, GitHub repositories with modified firmware.

⚠️ Note: Firmware from unknown sources may contain malicious code. Check other users' reviews before installing.

Connect the vacuum cleaner to the PC

• Turn off the vacuum cleaner.
• Press the Home and Power buttons for 10 seconds until the white light light lights up.
• Connect the USB-Type C cable to the vacuum cleaner and computer.
• Install drivers: Download the driver for MediaTek Preloader (for example, MTK_Driver_Auto_Installer) And you can install it. Without the drivers, the PC won't see the vacuum cleaner.
• Use the Roborock-Vacuum-Tool utility or SP Flash Tool for downloading firmware. Command to check the connection: fastboot devices If the device is detected, run: fastboot flash system custom_voice.img
• Reboot the vacuum cleaner: After successful firmware, turn off the cable and turn on the vacuum cleaner with the Power button.The first run can take up to 5 minutes.

If something goes wrong and the vacuum cleaner doesn't turn on:

• 🔄 Try to return the stock firmware through SP Flash Tool.
• 📞 Contact Xiaomi Support (but they may refuse if they find traces of modifications).

Method 3: Turning off the voice completely

If you don't like any of the voices available, you can turn off voice acting completely, either through the app or through manual settings.

Option 1: Through Mi Home:

1. Open the app and select your Roborock S6.
2. Go to Settings → General settings → Voice alerts.
3. Move the slider to the off position.

Option 2: Through the file system (for advanced users):

• Connect the vacuum cleaner to the PC in ADB mode (as in method 2).
• Execute the command to turn off the sound: adb shell settings put global voice_guidance_enabled 0
• Reset the vacuum cleaner.

After turning off voice alerts, the vacuum cleaner will:

• ✅ Silently cleaning.
• ✅ Report status only through light indicators and notifications in Mi Home.
• ❌ Do not warn with your voice about errors (for example, a stuck brush or low charge).

⚠️ Warning: Without voice alerts, you may miss critical errors such as engine overheating or wheel locks.

Common Mistakes and How to Avoid Them

When changing voices to Roborock S6, users often face problems.

1. Vacuum does not respond after firmware: Reason: incompatible firmware version or interrupted process Solution: return stock firmware via SP Flash Tool.
2. The voice changed, but it became robotic or distorted: Reason: damaged sound files in the firmware. Solution: download the firmware again and repeat the process.
3. Mi Home does not have a language change option: Reason: the region of the account does not support Russian. Solution: change the region to "Russia" or "Germany" (often there is Russian).
4. The vacuum cleaner constantly resets the voice settings: Reason: conflicting firmware and application versions. Solution: Update the Mi Home and vacuum cleaner firmware to the latest versions.

If you are not confident in your abilities, it is better to focus on official methods (change of language or turn off voice).
