Smart tech owners often face a situation where the notifications from the robot vacuum cleaner are barely audible, especially in large apartments or in the presence of background noise. The standard volume settings in the Mi Home or Xiaomi Home app are not always intuitive, and sometimes seem limited. In this article, we will discuss all the available ways to control the audio output of your device.
First of all, it's worth noting that most Xiaomi models (Mijia Vacuum, Roborock, Dreame) don't have a physical volume button on the body. All control is software-based, it's designed to protect against accidental changes by children or pets, but software constraints can be bypassed or customized if you know where to look for hidden settings.
There are several levels of adjustment, from basic volume switching in the application to a full replacement of the voice packet with a louder one. In some cases, a quiet sound can be the result of a software error that requires a reset. We will look at each method in detail so that you can choose the best option for your model.
Volume control through the official annex
The easiest and safest way to change the sound level is to use the official control interface. To do this, open the Xiaomi Home app on your smartphone. After logging in, find your vacuum cleaner card in the list of devices. Click on the device icon to go to the control panel. In the upper right corner of the screen, there is usually a button with three dots or a gear - this is the settings menu.
Inside the settings menu, you need to find a section associated with voice or sound. It can be called Voice Package, Volume or Voice Volume. There is often a slider or switch between Quiet, Loud and No Sound modes available. Note that on some models, the slider only adjusts the volume of system notifications, but does not affect the volume of voice support if you choose another language pack.
If you don't see the volume slider, maybe your model only supports switching between fixed levels. In this case, try changing the language of the voice packet. Sometimes Russian voice is quieter than English or Chinese because of the way you record audio files in the factory. Experiment with settings to find the most appropriate balance.
⚠️ Note: If the sound hasn’t changed after changing the settings in the app, try to close the app completely and restart your smartphone.The cache of the Xiaomi Home app sometimes prevents the instant application of new settings.
Changing voice packet and language
One of the most effective ways to make a vacuum cleaner louder is to change the voice pack. Developers often write different language versions with different amplitudes. For example, the standard Russian voice on the Roborock S5 or Xiaomi Vacuum Mop models can be written quieter than the English counterpart. To change, go to the device settings and select Voice or Voice.
In the list that opens, you'll see the available languages. If you select "English," the device downloads a new audio file. Once installed, try to start cleaning. Often, changing the language dramatically changes the perception of volume, even if the technical level of the decibels remains the same, due to a different tone and tone of voice.
Keep in mind that a new package requires a stable connection to the Wi-Fi network to load, and if the loading is interrupted, the vacuum cleaner may return to default or issue an error, and make sure that the battery is charged at least 20% before the procedure begins.

Use of third-party applications and modifications
For advanced users who don't like the standard features, there are alternatives, and one of the most popular solutions is to use modified versions of the app, such as Veilid or plugins for Home Assistant, which allow you to access hidden menus of engineering diagnostics.
In some models, you can find an Audio Gain or similar setting that regulates the signal amplification at the hardware level, which allows you to change the setting to make the sound much louder than the normal one, but you need to be careful about interfering with these settings.
- 🔍 Find it. IP-address of your vacuum cleaner in the router settings.
- 🔧 Install the device token through the plugin in Home Assistant.
- 📡 Use the command to access hidden sound parameters.
- ⚙️ Carefully change the gain value by testing the result.
⚠️ Warning: Using unofficial software and making changes to system files can lead to a "bricking" of the device.You act at your own risk. Always be able to perform a full reset before factory settings.
Technical Causes of Silent Sound
It's not always a software feature, and in some cases, the problem is the physical state of the speaker, and over time, it can get dust, wool, or moisture inside the body, which drowns out the sound, and the speaker in robot vacuum cleaners is usually placed under a protective grid, but small particles can still clog up the acoustic channels.
Check the speaker holes. They're often on the top panel or side of the body. Gently blow them with compressed air or use a soft brush. Don't use sharp objects, as you can damage the speaker membrane, which will lead to wheezing or no sound at all.
Also worth checking is the firmware version. Older versions of the software may have errors that affect the audio codec. Updating to the latest version through the app often solves playback problems. Go to the settings and click "Check Updates."
💡
Periodically wipe the speaker holes with dry cloth. The accumulation of dust in this area is the most common reason for the gradual decrease in volume over time.
Comparison of the volume of popular models
Different Xiaomi robot vacuum cleaners come with different speakers. If you're critical to a loud voice assistant, consider this when choosing a device. Below is a comparative table of volume levels for popular series.
| Model of the device | Type of speaker | Max. Volume (dB) | Features of sound |
|---|---|---|---|
| Xiaomi Vacuum Mop Essential | Mono, built-in | ~55 dB | Basic sound, often quiet |
| Roborock S5 Max | Improved speaker | ~65 dB | Clear voice, good hearing. |
| Xiaomi Robot Vacuum X10+ | Stereosystem | ~70 dB | High volume, deep bass. |
| Dreame L10 Pro | High-frequency | ~60 dB | A sharp but ringing sound |
As you can see from the table, more expensive models like the X10+ or Roborock flagships come with more powerful audio modules. If your current vacuum cleaner is in the budget segment, it won’t be possible to programmatically increase the volume above the physical limits of the speaker.
💡
The physical limitations of the speaker cannot be bypassed by software, and if the speaker is weak in design, replacing the voice packet will only have a negligible effect.
Frequent questions and problem-solving
Users often ask questions about not only the volume, but also the quality of the playback, such as why the robot started talking intermittently or why the sound disappeared after the upgrade, and in most cases, rebooting the device helps.
To reboot, press and hold the on and back buttons simultaneously for 5-10 seconds (the combination may vary depending on the model). After turning off, wait a minute and turn on the vacuum cleaner again. This will reset the audio driver's temporary errors.
If the sound is gone, check if the Do Not Disturb (DND) mode is set. In this mode, the vacuum cleaner may work, but all audible notifications are disabled. Check the DND schedule in the application.
