Modern smart home devices require regular maintenance of software to function without failure. Robot vacuum cleaners Xiaomi, Roborock or Viomi are no exception, as their algorithms for navigation and battery management are constantly being improved by developers. If you notice that your gadget has become worse to build a map, get stuck or simply stopped responding to commands, most likely it needs to update the system software.
The process of installing new firmware versions may seem complicated only at first glance, but in reality it only takes a few minutes of your time. It is critical not to ignore notifications about the availability of new versions, as they often contain fixes for critical security bugs. In this article, we will discuss in detail how to update the Xiaomi robot vacuum cleaner through the application, what to do if the process freezes, and how to avoid turning the device into a “brick”.
Why you need to update the firmware of the robot vacuum cleaner
Many users ignore pop-ups to suggest that you upgrade, believing that if a vacuum cleaner drives and sucks dust, it doesn't need anything else. However, system updates are not just about changing the numbers in the version, but often improving the logic of the engines and optical sensors. Developers release patches that optimize energy consumption, which directly affects the battery life of your device.
In addition, new software versions often add support for new features or improve compatibility with the smart home ecosystem, for example, after an update, voice control through new assistants may become available or an improved algorithm for bypassing obstacles, the engineering software inside the robot becomes stiffer, accidental reboots and connection errors with the Wi-Fi router disappear.
⚠️ If the robot began to move randomly or lose the map of the room, in 80% of cases this is solved by resetting to factory settings and then installing the latest version of the firmware.
It’s also worth mentioning that older versions of software may contain vulnerabilities that theoretically allow unauthorized access to your home network. Regular updates close these security holes. Mapping algorithms also become more accurate, allowing the vacuum cleaner to clean complex spaces with lots of furniture more efficiently.
Preparation of the device for the update procedure
Before you start downloading and installing files, you need to make sure that the robot and your smartphone are ready for this operation. First, check the battery charge: it should be at least 20%, and ideally, the robot should be standing at the charging station.
The second important thing is a stable Internet connection: the robot vacuum cleaner needs to be connected to the Wi-Fi network, and your phone needs to have Internet access. It is desirable that both devices are on the same network, although this is not always strictly necessary for cloud updates, but it greatly speeds up the process. Make sure that the version of the Mi Home app or Xiaomi Home is also relevant.
☑️ Readiness for renewal
If you plan to upgrade a device that was not previously associated with your account, do so before the procedure. Device binding is necessary so that the server can identify the model and offer the correct firmware file. Without authorization in the Xiaomi account, the process of updating through the cloud is impossible.
Step-by-step: Update via the Mi Home app
The easiest and safest way to update software is to use the official mobile application. The program interface is unified, so the actions for the Roborock S5, Xiaomi Vacuum Mop or Dreame models will be almost identical. Open the application on your smartphone and make sure that the status of the device is displayed as “Online”.
On the home screen, select your robot vacuum cleaner card. Usually, in the upper right corner or in the three-dot menu, you have to find the section related to general control or device information, and that's where the version check button is.
- 📱 Open the Mi Home app and go to the main screen.
- 🤖 Click on the icon of your robot vacuum cleaner to enter the control.
- ⚙️ Select the settings menu (three dots) in the upper right corner of the screen.
- 🔄 Find the "Update" or "Software Version" option and click "Check».
If the new version is available, the system will suggest downloading and installing it. Press the appropriate button and wait for the process to be completed. At this time, the robot can emit an audible signal and start moving the brushes to calibrate, which is normal behavior. Don't close the application and keep the smartphone screen active to control.
What to do if the update is stuck or not starting
Sometimes the process can run into technical difficulties: the progress bar gets stuck by 1%, 50% or 99%, or the update button is simply inactive. Often the problem lies in an unstable connection between the Xiaomi server and your router. In this case, try to switch your smartphone to the mobile Internet (3G/4G), leaving the robot connected to Wi-Fi, or vice versa.
Another common cause is a crowded app cache or an error in the management program itself. Try to close the Mi Home app completely through the Task Manager and run it again. If that doesn't work, it makes sense to uninstall the app and download it again, making sure that the right server is selected in your region (for example, Russia or China).
⚠️ Warning: If the update is more than 20 minutes in, don't be in a hurry to turn off the robot. Try rebooting the router first, and then if the robot responds to buttons, press the Reset button with a short press.
In some cases, manual restarting of the robot itself helps: Press and hold the on button or button combination (depending on the model) to turn it off, then turn it on again. After restarting, the status in the application should be updated, and the installation process may continue automatically or require re-starting.
Hidden causes of update errors
Comparison of Upgrade Methods: OTA and Manual Installation
Users may encounter two main firmware methods: Internet-based automatic (OTA) and manual. Automated is convenient but depends on the manufacturer's servers. Manual requires more action, but allows you to install a specific version of the software if an automatic update does not arrive.
Manual installation is often required for devices purchased in China (Global version) that are connected to European servers, or vice versa. In such cases, the server may assume that you already have the latest version, although there is a newer or more stable build for your region.
| Parameter | OTA (Through the annex) | Manual installation (File) |
|---|---|---|
| Difficulty | Low (automatically) | High (requires skills) |
| Risk of error | Minimum | Medium (human factor) |
| Speed. | Depends on the server. | Depends on the speed of downloading |
| Choice of version | Only the last one. | Any available |
For most users, it is recommended to use only the standard method through the application, as it guarantees the integrity of data. Manual firmware is the lot of enthusiasts who know exactly why they need a particular version of the software. An error in choosing a file can lead to a failure of the control module.
💡
Use only the official app update method unless you are an experienced user and do not understand the risks of manual firmware installation.
Common mistakes and ways to solve them
During the update process, users often encounter error codes that don't tell the average person, such as a "Network timeout" error indicating Internet problems, and a "Device busy" error indicating that the robot is busy completing a task or calibrating, in the first case you need to check the router, in the second - wait for the cleaning to finish.
If the app says “Update failed,” try clearing the app’s cache in Android/iOS settings. It’s also worth checking if the phone’s memory is full, as temporary update files can take up a significant amount of space. Sometimes it helps to simply reconnect the robot to the Wi-Fi network: remove the device from the app and add it again.
- 📶 Network Error: Check Wi-Fi Password and Frequency (Robots often only run at 2.4GHz).
- 🔋 Low Charge: Put the robot on base and wait for full charging before retrying.
- 🗑️ App cache: Clear the Mi Home app data in your smartphone settings.
- 🌍 Region: Make sure that the correct account region is selected in the application settings.
In rare cases, the problem may be on the side of Xiaomi servers.If other users in the forums also have connection problems, it may be worth waiting a few hours.
💡
Before updating, take a photo of the current room map in the application if it is complex. After updating, the map may reset, and the photo will help you navigate faster with the new calibration.
