Modern robot vacuum cleaners from Xiaomi are complex electronic devices that depend on the stability of the software. During operation, the user may face situations when the gadget stops responding to commands, hangs in the center of the room or loses connection to the wireless network. In such cases, a standard switch-off is often not enough, and deeper intervention in the operation of the device's operating system is required.
The process of rebooting or resetting can vary significantly depending on the model, whether it is a classic Mi Robot Vacuum, an advanced Roborock S7 or a budget Dreame. Wrong actions can lead to the loss of saved room maps or the need to reconfigure the connection to the router, which is time-consuming. So it is important to clearly understand the difference between a conventional shutdown, software reboot and a full reset to factory settings.
In this article, we will take a look at all the known ways to resuscitate your cleaning gadget, fix common bugs and restore it to work. You will learn how to properly use physical buttons on the case, what combinations to pinch to enter pairing mode and what to do if the device completely ceases to respond to any commands. For models released after 2023, it is often necessary to hold the buttons 10-12 seconds instead of the standard 5.
Differences between Shutting Down and Rebooting the System
Many users mistakenly believe that mechanically switching the power switch is equivalent to restarting a computer or smartphone. In fact, when you switch the Power switch to OFF, the device simply shuts down the main nodes, but does not always conduct the correct procedure for shutting down system processes. The robot's operating system can store temporary files or navigation cache, which can be damaged if the power is abruptly turned off.
A true soft reset initiates a sequential start-up of all services, sensor checks and recalibration of the gyroscopes, especially if the robot starts building an incorrect map or is stuck in one place. Software restart allows you to clear the memory of temporary errors that accumulate during long cleaning.
There's also the concept of Hard Reset, or full reset, which returns the device to factory settings, which removes all user data, including apartment maps, cleaning schedules, and Wi-Fi settings. Use this feature only when soft methods don't work, or when selling the device to a new owner. It's important not to confuse these concepts, so as not to accidentally delete the stored map of a multi-bedroom apartment.
⚠️ Warning: Before performing a full reset, make sure you have a backup card in the app if this feature is supported by your model, otherwise the route will have to be rebuilt.
Basic reboot through physical buttons
The most common and safe way to reanimate a robot vacuum cleaner is to use a combination of buttons on the top panel. Most Xiaomi ecosystem models, including Roborock and Mijia, have a standard reboot algorithm. This usually requires you to press two main control buttons simultaneously. Depending on the interface, these can be Home and Turn on buttons, or Local Cleanup and On buttons.
The process is as follows: hold the specified buttons for 5-10 seconds until the device emits an audible signal or voice message about the start of the reboot. At this point, the indicators can start flashing in a certain mode, signaling the transition to the system maintenance mode. Do not release the buttons ahead of time, otherwise the command will not be received by the controller.
☑️ Checklist for the correct reboot
If the robot has released the buttons, but the screen or the lights have gone out and no longer caught fire, the battery may have run out, so you need to put the device on the charger and wait 15-20 minutes, then repeat the procedure, and sometimes the system blocks the start at a critically low charge level to protect the battery.
Reboot via the Mi Home mobile app
For smartphone owners, the most convenient way to control the robot is to use the official Mi Home or Xiaomi Home app, which allows you to reboot remotely even if you are in another room, but to do so, the robot must be connected to a Wi-Fi network and displayed on the list of devices as “Online”.
To perform a software reset, open your device card in the app. The top right corner usually contains the settings menu (three dots or gears). The list that opens will look for "Device settings" or "General settings", where the "Reboot" or "Reboot" option is often hidden. Pressing this button sends a command to the device, which will independently perform the turn off and on cycle.
The advantage of this method is that it passes all the software integrity checks before starting, and the application can suggest updating the firmware if it finds a new version, which often solves the problems with hanging, and if the robot is in the status of "Offline", this method will not work, and you will have to use physical access to the buttons.
Resetting Wi-Fi settings and pairing mode
A common reason users are looking for a way to reboot is to lose their Internet connection. The robot can operate autonomously, but it stops transmitting statistics and does not respond to commands from the phone, which requires not a complete restart of the system, but a reset of the network module and transfer the device to a pairing mode.
To switch to pairing mode on most Xiaomi and Roborock models, you need to simultaneously press the Home and Power buttons, which you need to hold until the voice assistant reports the transition to configuration mode or until the Wi-Fi indicator starts flashing quickly, and then you can re-add the device to the application by entering the password from your network.
Importantly, some models, such as the Roborock S5 Max or S6, may require three buttons to be pressed simultaneously or using a hidden reset button under the lid.If standard combinations don't work, try clamping only the power button for 15 seconds - on some firmwares this causes a forced reset of network settings without removing the card.
| Model of the device | Button combination | Duration | Indication |
|---|---|---|---|
| Mi Robot Vacuum 1S | Home + Food | 5-7 seconds | Wi-Fi flashing |
| Roborock S50/S55 | Home + Food | 5 seconds | Voice + blinking |
| Dreame F9 | Home + Food | 3 seconds | Sound signal |
| Roborock S7 | Home + Food | 6 seconds | Network indicator |
Removing freezes and navigation errors
When a robot vacuum cleaner freezes in place, hums the engine but doesn't move, or spins endlessly around its axis, it often indicates a software failure of sensors. The laser rangefinder (LDS) may not have had time to calibrate, or there's too much data about obstacles in the memory buffer, in which case a simple reboot is often the only solution.
If a standard shutdown doesn't work, you can try the cold start method, which requires you to switch the power switch to OFF, wait at least 30 seconds (to drain the capacitors), and then turn the device on again, which helps to reset static electricity and restart the engine controllers.
If the robot is making voice error messages (e.g., "Error 4" or "Wheel stuck") immediately after turning on, try to clean the collision sensors and wheels of dust. Sometimes the software failure is caused by physical contamination, which the system perceives as a critical error.
⚠️ Warning: If the robot continues to produce wheel or brush error after reboot, don't ignore it. Prolonged operation with the mechanism locked can cause the engine to burn out.
Full reset to factory settings (Hard Reset)
When none of the previous methods work, or you plan to sell a device, you need to perform Hard Reset, which completely erases all user data, returning the gadget to the "out of the box" state. Be careful: after that, the map of the room will have to be rebuilt and all schedules will be deleted.
On most Xiaomi models, the full reset is done with a combination of Home and Turn on buttons, but you need to hold them much longer — about 10-15 seconds. The device will warn you by voice that the reset is starting and ask you to confirm the action (sometimes you need to press the local cleaning button).
What happens when you drop a card?
There is also a hidden way to reset through the engineering menu available on some firmware, which requires you to quickly press the local cleaning button 5 times or perform a sequence of taps, but this method is not recommended for ordinary users, as it can lead to unpredictable behavior of the system.
Typical problems after rebooting
After a successful reboot, the robot may behave unusually, such as starting to build a new map instead of using the old one, or repeatedly requesting Wi-Fi connectivity. This is normal if the reset affected the memory module or network settings. Give the device time (about 5-10 minutes) to fully initialize all systems.
Sometimes there's a problem where the robot turns on but doesn't start cleaning on a schedule. Check the Mi Home app if the time is lost. When the power is completely out (for example, when the power is down for a long time), the internal clock can go off and the schedule won't work. The timing happens automatically when you connect to the Internet.
If the device is not behaving properly after all the manipulations, check the software version. Go to the device settings in the application and click "Update Check." Installing current firmware often fixes bugs that caused frequent reboots.
💡
Tip: If the robot often loses the map or requires a reboot, try cleaning the laser rangefinder (the turret at the top) of dust and check if it rotates freely when turned on.
💡
Regularly restarting once a month helps to maintain the navigation system and prevents the accumulation of software errors.
