Why Bluetooth doesn’t work on Xiaomi vacuum cleaner and how to fix it
Xiaomi vacuum cleaners are not just cleaning devices, but full-fledged gadgets with support for smart functions. One key feature is Bluetooth connectivity, which allows you to control the robot through the Mi Home or Dreamehome app, update your firmware without Wi-Fi, and use voice assistants. However, many users face the problem: the Bluetooth module either does not activate, or the phone does not see the vacuum cleaner in the list of available devices.
The reasons can range from the usual (a discharged battery or a module turned off in the settings) to the technical (a firmware failure or hardware malfunction).In this article, we will discuss all the ways to turn on Bluetooth on the vacuum cleaners Xiaomi Mi Robot, Dreame and Viomi, and give recommendations for eliminating typical errors. If your robot vacuum cleaner does not appear in the list of devices, do not rush to carry it to the service: in 90% of cases, the problem can be solved yourself.
It's important to understand that on some models (e.g. Xiaomi Mi Robot Vacuum-Mop 2 Lite), Bluetooth only turns on automatically after you first connect to Wi-Fi. This is a feature of the firmware that few people know about. If you've just unpacked the vacuum cleaner, set it up through the app according to the instructions, and then try connecting to Bluetooth.
What Xiaomi models support Bluetooth
Not all Xiaomi robot vacuum cleaners are equipped with Bluetooth module, here is the full list of models that support this technology:
- 🤖 Xiaomi Mi Robot Vacuum-Mop 2 Pro (and all modifications: STYJ02YM, STYTJ02YM)
- 🤖 Xiaomi Mi Robot Vacuum-Mop P (STYJ06YM)
- 🤖 Dreame D9, Dreame D10 Plus, Dreame Z10 Pro (all versions)
- 🤖 Viomi V3, Viomi SE (firmware not less than 3.5.8)
- 🤖 Xiaomi Mi Robot Vacuum E10 (only for local management)
If your model is not on the list, check the specifications on the official website or in the instructions. For example, the budget versions of the Mi Robot Vacuum-Mop Essential or Mi Robot Vacuum 1C work only over Wi-Fi and do not have a Bluetooth module.
| Model vacuum cleaner | Bluetooth version | Supported functions |
|---|---|---|
| Xiaomi Mi Robot Vacuum-Mop 2 Pro | 5.0 | Management through the application, OTA-Update, voice assistant |
| Dreame D10 Plus | 4.2 | Local control, setting up cleaning areas without Wi-Fi |
| Viomi V3 | 4.0 | Connecting to smart speakers, manual activation of cleaning |
| Xiaomi E10 | 5.0 (limited) | Only for diagnostics and updates |
⚠️ Attention: On vacuum cleaners Xiaomi with dual communication module (Wi-Fi) + Bluetooth) may need to choose the priority connection method when you first turn on. If you click "Cancel" at this stage, Bluetooth will remain disabled until the settings are reset.
Method 1: Enabling Bluetooth via a button on the body
The easiest method is to activate the module manually, and most Xiaomi and Dreame models have a combination of buttons:
- Make sure the vacuum cleaner is on (the indicator is white or blue).
- Press the Home button (or Spot Clean on some models) for 5 seconds until you hear the beep.
- After the signal, release the button - the indicator should start flashing blue (pairing mode).
- Open on your phone Settings → Bluetooth and find a device called MiRobot_Vacuum_XXXX (where XXXX — last digits of the serial number).
If the vacuum cleaner doesn't respond to the hold of the button, check the battery power. At levels below 20%, many models lock the Bluetooth module to save energy. Connect the device to the charging station and try again in 10 minutes.
Charge the vacuum cleaner to 50% or more
Make sure the phone is within 1 meter radius of the vacuum cleaner
Disable VPN and flight mode on the phone
Reboot the Mi Home app (if used)
-->
On some models (e.g. Dreame D9), you need to press the power button + the clean button at the same time for 3 seconds to activate Bluetooth. The exact combination for your model can be found in the manual or on the sticker under the vacuum cleaner cover.
Method 2: Activate with Mi Home or Dreamehome
If the physical button doesn't work, try turning Bluetooth on software.
- Open the Mi Home app (or Dreamehome for Dreame vacuum cleaners).
- Go to the section with your vacuum cleaner (if it has already been added).
- Slap the icon. ⚙️ Settings in upper right corner.
- Select Device Settings → Additional → Bluetooth Mode.
- Activate the switch to Turn on Bluetooth.
If the menu does not include Bluetooth Mode, your model does not support this feature, or you need a firmware update. Check the version in the same settings section: the current firmware should be at least 3.3.9 for Mi Robot and 4.2.1 for Dreame.
💡
If the vacuum cleaner doesn't show up in the Mi Home after reset, try adding it manually: press + → Add Device → Robot vacuum → select a model and follow the instructions. At the connection stage, the system can suggest choosing between Wi-Fi and Bluetooth - choose the second option.
⚠️ Note: After updating your firmware via Bluetooth (for example, on Viomi) V3) The module may temporarily shut down. In this case, perform a hard reboot: hold the power button for 10 seconds until the vacuum cleaner emits a double beep.
Method 3: Reset settings for Bluetooth recovery
If none of these things worked, there might have been a software failure, and then you might want to reset to factory settings.
- Turn off the vacuum cleaner (hold the power button for 3 seconds).
- Press the power button + the cleaning button for 10 seconds at the same time.
- Release the buttons when you hear a beep (usually two short beeps).
- Wait 1-2 minutes - the vacuum cleaner will restart and return to the factory settings.
After discharge:
- 🔄 Bluetooth will turn on automatically in pairing mode (blinking blue indicator).
- 📱 The Mi Home app will require you to re-add the device.
- ⚠️ All stored room maps and cleaning settings will be deleted.
The Dreame models do the reset differently: press the power button 4 times in a row, then hold it for 5 seconds, and then the vacuum cleaner will issue a voice message in Chinese — that's okay, just wait for the reset.
What to do if Bluetooth does not work after resetting
Typical errors and their solutions
Let’s discuss the most common problems and ways to eliminate them:
| Mistake. | Reason. | Decision |
|---|---|---|
| Phone can't see vacuum cleaner | Bluetooth turned off on phone or vacuum cleaner | Check your phone settings and restart the vacuum cleaner |
| The conjugation is interrupted. | Weak signal or interference from other devices | Remove sources of interference (microwaves, 5 GHz routers) |
| Bluetooth is turned on, but immediately shut down | Low battery charge or firmware failure | Charge the vacuum cleaner to 100% and update the software |
| The application does not connect via Bluetooth | An outdated version of Mi Home | Update the app in Google Play/App Store |
If the vacuum cleaner connects over Bluetooth, but immediately breaks the connection, try turning off the power saving for the Mi Home app in the phone settings. On Android, this is how you do it:
- Go to Settings → Applications → Mi Home → Battery.
- Choose No Limits.
- Activate the option to Allow work in the background.
💡
On iPhones, Bluetooth connectivity problems are often solved by restarting the phone, and check if Low Power is on, which can block a stable connection.
Bluetooth vs Wi-Fi: Which is Best for Vacuum Control
Many users are asking themselves, which way of connecting is preferable? Each option has pros and cons:
- ✅ Bluetooth:
- ❌ Cons:
- ✅ Wi-Fi:
- ❌ Cons:
For most users, the best solution is to use Wi-Fi for primary control and Bluetooth for backup (for example, if the Internet is turned off or the router is broken). On the Dreame D10 Plus and Viomi V3 models, you can even connect to both channels at the same time, which ensures maximum stability.
