Smart tech owners often face a situation where the device begins to actively communicate with the owner in a language that requires translation. Xiaomi’s robot vacuum cleaners, including the popular Roborock, Mijia and Viomi lines, are equipped with a voice alert system that reports the status of cleaning, charge level or problems. Understanding these phrases is critical for the proper operation of the equipment.
The default Chinese voice packet can be confusing, and the English interpreter in the app is not always available or accurate. Voice notifications serve as the main communication channel between the device and the user, especially if the smartphone is in another room. In this article, we will detail what your janitor is saying, how to interpret error codes, and why he may be silent at the most inopportune moment.
Often users ignore the audio signals, relying only on the indication in the Mi Home app. However, if the Wi-Fi connection is unstable, local audio commands remain the only way to diagnose. Knowing the exact translation of phrases helps to instantly respond to a device stuck or maintenance need, prolonging the life of the motor and battery.
Main Status Reports in Normal Work
In normal operation, the robot vacuum cleaner tells you that cycles are beginning and ending, and that human intervention is needed. The standard phrase "Starting to clean" is pronounced immediately after receiving a command from a smartphone or pressing a button on the case, which confirms that the navigation system is activated and the maps are loaded into memory.
Special attention should be paid to the reports of completion of work. The phrase "Cleaning complete" means that the device has gone all the way to base and returned to base. If you hear "Docking", the robot reports that it is in the process of finding a charging contact, at which point you should not block the path to the base or move it.
⚠️ Warning: If the robot repeats the phrase "Returning to dock" several times in a row, but does not dock, check the contacts at the charging station.
There's also a lot of silence messages, and when you activate Do Not Disturb in the app, the robot can voice-activate the transition to silent mode, reducing the suction power, which is useful if you work at home or put your child to bed, because the noise level of the turbine is significantly reduced.
Decoding error codes and problem situations
The most important part of the voice interface is the fault detection system. When the Xiaomi robot vacuum cleaner says "Error" followed by a number, it's a direct signal of failure. For example, "Error 1" usually indicates a main wheel getting stuck. In this case, the device recommends: "Please clean the main brush" or checks the freedom of rotation of the wheels.
Sensor errors are also made clear. The message "Please clean the sensor" is often heard when a laser rangefinder (LDS) on a tower or floor sensors are contaminated. This is critical for mapping: if the laser is closed with dust, navigation becomes impossible, and the robot can move around the room chaoticly.
- 🤖 Error 4: Wheel suspended – the wheel got stuck in the air, the robot stuck on the doorstep or carpet.
- 🌀 Error 8: Suction fan error - problem with the fan engine, possibly getting into large debris.
- 🧹 Error 10: Side brush error – the side brush is blocked with threads or hair.
- 📡 Error 15: Lidar error: Laser navigation module malfunction or lock.
Some models, such as the Xiaomi Vacuum Mop 2 Pro, can report errors in more detail by pointing to a specific node. If you hear a recurring error sound but can't understand the number, look at the Mi Home app, which will show the same code in real time as the voice message, but with a text transcript in Russian.
What if the robot is silent when it makes a mistake?
Navigation system and map messages
Smart vacuum cleaners build a map of the room, and this process is also accompanied by comments. The phrase "Creating map" sounds at the first start or after resetting. During this period, the robot explores the perimeter, and it can not be disturbed. Interrupting the process can lead to incorrect preservation of the geometry of the room.
If the device loses orientation, you might hear "Position lost," which is if you move the robot while cleaning or you change the furniture abruptly, and then the gyroscope and accelerometer try to re-determine the coordinates by scanning the surrounding space.
When working with virtual walls and no-go zones, the robot can warn: "Restricted area" (No-go zone), which means that it has approached the boundary that you set in the application and turns around so as not to violate the rule, and you can also report that the map is saved or updated, which is a positive signal of successful data synchronization.
Battery status and charging process
Energy efficiency is a key parameter, and the robot is constantly monitoring the charge. When the battery goes down, the phrase "Low battery, return to charge" is heard. The device interrupts the cleaning itself to get to the base. If the charge is critical, the robot can stop in the middle of the room and say, "Please charge me."
When you charge, the statuses change. Charging is the standard state. If the contacts are contaminated, the robot can say "Charging error," even if it's on the base, a common problem that is solved by dry-clothing the contacts.
| Communication (RU/EN) | Indication | Action. |
|---|---|---|
| Low battery / Low battery | Orange indicator | Automatic return to base |
| Charging / Charging | Blinking white | Waiting for 100% charge |
| Charging completed / Fully charged | Permanent white. | Ready to work. |
| Charge error/charge error | Red indicator | Checking the database's contacts |
⚠️ Warning: Do not leave the robot vacuum cleaner on the base with a discharged battery for a long time (months). Lithium-ion batteries can go into deep discharge, after which it will be impossible to restore them with standard methods.
Maintenance and care of the device
Regular maintenance extends the life of the device, and the robot is reminded of it in a voice. The most common phrase is "Please clean the filter). HEPA-The filter is clogged with fine dust, and if it is not shaken out, the suction power drops, and the motor overheats.
There is also a message about the need to clean sensors or replace the main brush. If the robot says "Main brush needs cleaning", check if the hair is wound on the shaft. In modern models with a self-cleaning function (for example, the Xiaomi Robot Vacuum X10+ station), you may hear the command to empty the dust container if it is full.
- 🧼 Filter: Wash with water only after drying (24 hours).
- ✂️ Brush: Cut the wound hair off the ends of the roller regularly.
- 👁️ Sensors: Wash with a soft napkin the sensors of the fall and LDS-tower.
Ignoring these requests causes the robot to work quieter and less clean. Xiaomi's self-service system is built on timers and pressure sensors, so voice prompts are the most accurate here.

Changing language and voice packets
Many users prefer to change their Chinese or English voiceover to a more understandable one, and for this, in the Mi Home app, you need to go to the device settings, select Settings → Voice, and there is a choice of several language packages, including Russian, if supported by a particular model.
If Russian is not on the list, you can use third-party voice packets by downloading them through the developer mode, but this requires technical knowledge.
1. Open the Mi Home app.
2. Select your robot vacuum cleaner.
3. Press the three dots in the upper right corner.
4. Go to Settings -> Voice Package.
5. Select the desired language and click "Download".Once the new package is installed, the robot will confirm this with the phrase "Voice package updated" in the new language, and it is worth noting that the download is done over the Internet, so make sure that the robot is connected to Wi-Fi.
💡
If the robot doesn't speak after changing its language, try turning it off completely with a button on the body, waiting 10 seconds and turning it on again.
💡
Changing the voice packet does not affect the cleaning algorithms, but it significantly improves the comfort of interaction with the device, especially when diagnosing errors.
