Xiaomi's robot vacuum cleaner is a smart assistant that should make cleaning easier, not more trouble, but what if the device suddenly starts to behave strangely, like going around in circles, not coming back to base, making incomprehensible sounds, or refusing to turn on at all?
In this article, we will look at all the typical glitches of Xiaomi robot vacuum cleaners, from Mi Robot Vacuum models to Dreame and Viomi, and give step-by-step instructions for their elimination. You will learn when you can solve the problem yourself, and in which cases you should contact the service center.
Important: If your vacuum cleaner is warranted, some manipulations (such as disassembling the case or firmware) can cancel it.
1. Robot Riding in a Ring or Chaotically Moving: Causes and Solutions
One of the most common problems is that a robot vacuum cleaner starts to describe circles, gets stuck in one place, or moves in zigzags ignoring obstacles, most often due to a gyroscope malfunction, contamination of sensors, or a malfunction in the firmware.
The first thing to check is:
- 🧹 Sensor cleanliness: Infrared sensors and a camera are placed on the front bumper and bottom of the body (in models with a high-speed camera). LDS). Wipe them with a soft napkin soaked in alcohol.Dust or hair can block the signal.
- 🔄 Calibrate the gyroscope. Put the vacuum cleaner on a flat surface, turn it on and lift it 10 to 15 cm above the floor. Hold it for 5 to 10 seconds, and it will reset the sensor readings.
- 📱 Firmware update. Go to the Mi Home app (or Dreamehome for the respective models) and check for updates in the Device section. → Settings → Update of the PO.
If the problem persists, try resetting to factory settings:
- Open the Mi Home app.
- Choose your vacuum cleaner → Settings (⚙️) → General. → Resetting settings.
- Confirm the action. Once the robot is restarted, it will return to standard parameters.
💡
If the Xiaomi S10+ or Dreame D9 robot continues to glittle after reset, try turning off the Real-Time Maps feature in the cleaning settings.
2.The vacuum cleaner does not return to base: what to do?
The robot must automatically return to the station when the battery is below 20% or cleaning is complete.
External factors:
- 🔌 Power base. Make sure the station is plugged in and the light is green/blue. Try another cable or outlet.
- 📏 Distance and obstacles: maximum distance between the robot and the base is 8 meters (no walls.
- 💡 Lighting. In the dark, infrared sensors are worse. Turn on the lights or set the base in a more lit place.
Program settings:
- In the Mi Home app, go to Device Settings → Map → Edit the map.
- Make sure the base area is marked correctly (house icon) and move it manually if necessary.
- Activate the option to always return to base after cleaning (if any in your model).
What if the robot loses its base after the upgrade?
If the robot stubbornly does not find the station, try to reinstall the base in another place - sometimes even a 30-50 cm offset helps. Also check whether the station is on a carpet with a high pile: sensors may not recognize it due to uneven surface.
Errors and sound signals: decoding and actions
Xiaomi's robot vacuum cleaners report problems via voice messages (in English/Chinese) or beeps. Here's a transcript of the most common ones:
| Signal/Message | Reason. | Decision |
|---|---|---|
| Continuous squeak (5 times) | Blocked wheels or brushes | Clean the side brushes and check the mobility of the wheels. |
| "Check the side brushes" | The sidebrush is jammed or broken. | Remove the brush, remove the wound hair/threads, check the axis |
| Red indicator + "Error" sound | Problem with battery or charging | Clean the contacts on the base and robot, check the power supply |
| Voice: "The dust bin is full" | The garbage container is overflowing | Empty the container and clean the filter. |
| The sound of "Di-dee-dee" (3 times) | Problem with the collision sensor | Wipe the front bumper, check the spring mechanism |
Critical error: If the robot emits a long continuous signal and does not respond to buttons, this may indicate a short circuit in the battery.
For models with a display (such as the Xiaomi Mi Robot Vacuum-Mop 2 Pro), error codes are displayed on the screen. The full list can be found in the user manual or on the Xiaomi website (support section).

4. Charging problems: not charging or discharged quickly
If the Xiaomi robot vacuum cleaner doesn’t charge or the battery goes down in 10-15 minutes, the reasons may be as follows:
- 🔋 Battery wear and tear: Average battery life is 2-3 years (300-500 charge cycles) If the robot is older, it may need to be replaced.
- 🔌 Bad contact. Oxidized or contaminated contacts on the base or robot prevent charging. Clean them with a lasticle or alcohol.
- 📉 Power controller failure, sometimes full discharge helps + Charging: let the battery sit down to 0%, then put it on the station for 12 hours.
How to check the status of the battery:
- In the Mi Home app, open the device information.
- Find the Battery Status or Health section (in some models, it is displayed as a percentage).
- If the value is below 60%, the battery needs to be replaced.
Check the voltage in the outlet (220V)|Look at the cable for damage |Clear contacts on the robot and base |Try another charging station (if any) |Reset the battery settings in the application-->
⚠️ Warning: Never use non-original chargers! Xiaomi robot vacuum cleaner battery is sensitive to voltage. Inappropriate power supply can knock it out.
5. Mi Home app malfunction: synchronization and errors
Sometimes the problem isn't with the vacuum cleaner itself, but with the Mi Home or Dreamehome app crashing, and the symptoms are: the robot doesn't respond to commands from the phone, the map doesn't update, the device disappears from the list.
Solutions:
- 📱 Restart the app. Close Mi Home through the multitasking menu and reopen.
- 🔄 Reconnect the device: In the app, remove the vacuum cleaner from the list of devices. Press the reset button on the robot (usually under the lid or next to the power button). Add the device again via Add the device (+) → Robot vacuum cleaner.
- 🌐 Change server region. In your Mi Home account settings, select Mainland China (sometimes giving you access to additional features).
