How to properly restart the vacuum cleaner Xiaomi Mijia: all the ways from a soft restart to a complete reset

Xiaomi Mijia robot vacuum cleaners have become an integral part of smart homes, but even the most reliable appliances sometimes fail. Hanging during cleaning, connecting errors to the application or inadequate device behavior are all problems often solved by a simple reboot. However, not all users are aware that Xiaomi vacuum cleaners have several types of restarts, from a soft restart to a full reset to factory settings.

In this article, we will discuss in detail all the ways to reboot for different Mijia models (including: 1C/1S/STYJ02YM And others, explaining when to use it, and warning against common mistakes, and learning how to bring a vacuum cleaner back to life without going to a service center -- even if it's no longer responsive to commands.

It is important to understand that the reboot procedure depends not only on the model, but also on the cause of the failure. For example, hanging during cleaning is usually solved by a soft restart, whereas firmware errors may require a hard reset. We will also reveal little-known nuances - for example, why some Xiaomi vacuum cleaners do not respond to the on button after a software update.

If your robot vacuum cleaner is acting strangely, don't rush to carry it in repair. 80 percent of the time, it's solved by the right reboot, and the key is to follow the instructions for your particular model and not miss the important steps.

1.When do you need to restart the Xiaomi Mijia vacuum cleaner?

Not all the weird behavior of the device requires a restart, sometimes it's enough to clean the sensors or reconnect the vacuum cleaner to the application, but there are a number of situations where a reboot becomes necessary:

• 🤖 The vacuum cleaner got stuck during cleaning and does not respond to commands from the application or remote control
• 🔄 The device spins in one place or moves along meaningless trajectories
• 📱 Mi Home app shows connection error (Device offline) even though vacuum cleaner is enabled
• 🔋 After updating the firmware vacuum cleaner does not turn on or works incorrectly
• 🎛️ Sensors stopped responding to obstacles (vacuum cleaner bangs on furniture)
• 📛 The screen (if any) displays an error code that does not disappear after cleaning.

Reboots are especially often required after failed software updates, because Xiaomi Mijia vacuum cleaners receive firmware from the air, and sometimes this process is flawed. STYJ02YM Often faced with the fact that after updating the vacuum cleaner ceases to see the base or incorrectly builds a map.

Critical information: If the vacuum cleaner emits a continuous sound signal and flashes a red indicator, this is a sign of a hardware malfunction (for example, a jammed motor or a faulty battery), in this case, rebooting will not help, and repeated attempts to restart can exacerbate the problem.

2.Soft reboot (restart) - the safest way

Soft restart is like a smartphone reboot, and all the settings are saved, and the device just restarts its operating system, which is 70 percent effective and completely safe.

For most Xiaomi Mijia models (including: 1C, 1S, STYJ02YM, S5/S5 Max, the procedure looks like this:

1. Find the on-line button on the vacuum cleaner body (usually it is one and located on top).
2. Press and hold it for 10-15 seconds until you hear the beep.
3. Release the button and the vacuum cleaner will turn off.
4. Wait 30 seconds (this is important!), then press the switch again.

If your model is equipped with a touch button (for example, Mijia). 1T), slightly different:

1. Briefly tap the sensor to turn on (if the vacuum cleaner is off).
2. Hold your finger on the sensor for 20 seconds until the indicator flashes yellow.
3. Let go and wait for a full shutdown (about 1 minute).
4. Turn the vacuum cleaner on with a short press.

After a soft reboot, the vacuum cleaner should work normally, and if the problem persists, move on to the next method.

Make sure the vacuum cleaner is not on base (remove from charging)

Check the battery charge (at least 20%)

Clean the main sensors from dust

Prepare a screwdriver (for models with a hidden reset button)

3 Hard reset – when a soft reset does not help

If the vacuum cleaner does not respond to a soft restart or behaves inadequately (e.g., does not see the base, does not build a map), a hard reset may be required.This method returns the device to factory settings, so all stored room maps and user settings will be deleted.

For most Xiaomi Mijia models, the procedure looks like this:

1. Turn off the vacuum cleaner (hold the 10 seconds switch on if it doesn't respond).
2. Turn the device over and find the hidden reset button (usually located near the wheel or under the battery cover).
3. Use a thin object (clip, toothpick) to press a button, hold it for 5-7 seconds until you hear a double beep.
4. Wait 2-3 minutes – the vacuum cleaner will automatically turn on and begin the initialization procedure.

For models with removable batteries (such as early versions of the Mijia 1), the algorithm is different:

1. Turn the vacuum cleaner off the power.
2. Remove the battery for 10 minutes.
3. Install the battery back and turn on the device.
4. If the vacuum cleaner does not turn on, hold the power button for 15 seconds.

Important! After a hard discharge, the vacuum cleaner will need to be reconnected to the Mi Home app and set up a map of the room, STYJ02YM) Suction settings and cleaning schedules are also reset.

4.Reboot via the Mi Home application - remote method

If the vacuum cleaner is connected to the Mi Home app but is not running smoothly, you can try rebooting it remotely, a method that is suitable for troubleshooting software failures when the device responds to commands but behaves strangely (e.g., not building a map or ignoring virtual walls).

Instructions are Step-by-step:

1. Open the Mi Home app and select your vacuum cleaner.
2. Go to the Device Settings → General settings.
3. Find Reboot (or Restart in English).
4. Confirm the action - the vacuum cleaner will turn off and turn on on itself in 1-2 minutes.

If your app doesn’t have a reboot button, try an alternative way:

1. In the main menu of the vacuum cleaner, click on three dots (⋮) top-right.
2. Choose Remove the device (don’t be afraid – it won’t remove it forever).
3. Confirm removal, then add vacuum cleaner again via Add device → Robot vacuum cleaner.
4. After reconnecting, the vacuum cleaner will automatically restart.

This method also helps if the vacuum cleaner can’t see the base station or permanently loses connection to Wi-Fi. After a reconnection, a stable connection is usually restored.

💡

If the vacuum cleaner does not appear in the list of devices after rebooting through the application, check whether its Wi-Fi network has changed. Some models connect to the network by default after reset (for example, after resetting, Xiaomi_XXXX). In this case, find it in the router settings and connect to re-bind.

5. Features of the reboot for popular Xiaomi Mijia models

Despite the general principles, different models of Xiaomi vacuum cleaners have their own nuances of reboot. In the table below, we have collected key differences for the most common devices:

For the model STYJ02YM There is an additional nuance: if the vacuum cleaner does not respond to a normal reset, try resetting the Wi-Fi network:

1. Turn the vacuum cleaner over and find a small hole with the inscription RESET near-label.
2. Press and hold the button inside the hole for 5 seconds (the signal should sound).
3. Wait. 2 Minutes – the vacuum cleaner will create a new access point Xiaomi_Vacuum_XXXX.
4. Connect to it and re-set up Wi-Fi in the app.

Models. S5 Max and S6 They have another feature: after a hard reset, they may require an update to the room map. If the vacuum cleaner starts to drive randomly after the reboot, remove the old card in the application and allow it to build a new one.

💡

Before the hard reset of the Mijia model 1S or STYJ02YM Check the firmware version in the app if it is older than 3.5.8, you may need to manually update it through the firmware file after reset (instruction in Section 6).

6.Reboot after a failed firmware update

One of the hardest things is when the vacuum cleaner freezes during or after a software update, and it stops turning on. 1C/1S In such a situation, standard reboot methods may not work.

Algorithm of action:

1. Turn off the vacuum cleaner from the charging base and wait 5 minutes.
2. Hold the switch for 30 seconds (even if there is no reaction).
3. Connect the vacuum cleaner to charging and leave for 1 hour - sometimes the device is self-restored.
4. If the indicator does not light up, remove the battery (if possible) for 10 minutes.
5. Repeat the switching attempt.

If the vacuum cleaner is turned on but gives a firmware error (Error 10 or Update failed), you will need to manually update:

1. Download the latest firmware for your model from the official Xiaomi website (support section).
2. Unpack the archive and rename the file to vacuum.ota.
3. Copy the file to an empty microSD card (FAT32).
4. Insert the card into the vacuum cleaner (slot is usually under the cover).
5. Hold the 10 seconds button and the update process will begin (the indicator will flash blue).

Attention! Do not remove the memory card or turn off the vacuum cleaner during the upgrade. The process can take up to 20 minutes. If the indicator stops flashing, but the vacuum cleaner does not turn on, repeat the procedure with another memory card (sometimes the problem is incompatibility of the drive).

7.Typical reboot errors and how to avoid them

Many users are making problems worse by performing a reboot incorrectly, and here are the most common errors and their consequences:

• ⚡ Interrupting the update process – if you turn off the vacuum cleaner while blinking with a blue indicator, this can lead to loss of firmware and the need to flash through SD-map.
• 🔋 Resetting at low battery charge – if the charge level is below 15%, the vacuum cleaner may not complete the initialization procedure after restarting.
• 📱 Using unofficial firmware – this often leads to a device lock or Error 12 error (hardware incompatibility).
• 🔧 Pressing the reset button unnecessarily – frequent hard restarts can cause the device’s flash memory to wear out.
• 🌡️ Reboot at high temperature – if the vacuum cleaner is hot (for example, after a long cleaning), let it cool for 30 minutes before restarting.

It is especially dangerous to interrupt the calibration process of the sensors, which occurs after a hard reset. If the vacuum cleaner emits a series of audio signals and spins slowly, do not turn it off!

⚠️ Attention: If after rebooting the vacuum cleaner starts to move in circles or hit obstacles, this is a sign of improper calibration of the gyroscope. Repeat the hard reset and make sure that the vacuum cleaner is on a flat surface during initialization. Do not put it on a carpet or soft coating!

Another common problem is that the vacuum cleaner doesn't connect to Wi-Fi after the reset.

1. Make sure the router is running in 2.4GHz mode (5GHz not supported).
2. Turn off filtering in the router settings MAC-address.
3. Restart the router before reconnecting the vacuum cleaner.
4. If a Mesh system is used, connect the vacuum cleaner to the main node.

8.When the reboot doesn't help - what do you do next?

If you've tried all the methods, but the vacuum cleaner still doesn't work, maybe the problem lies deeper.

• 🔍 Diagnostics of hardware malfunctions: Check if the brushes rotate manually (if jammed, cleaning or replacement is required); listen to whether the fan is working (you should hear the noise of air when you turn on); inspect the wheels for stuck debris.
• 📡 Connection problems: Make sure the vacuum cleaner is not connected to another Wi-Fi network (like your neighbor). VPN On the phone – sometimes it interferes with the connection to the Mi Home.
• 🔧 Service centers: If the vacuum cleaner does not turn on at all (no indication), the control board may be faulty. If an Error 5 error (motor problem) requires professional diagnostics. Warranty repair is possible only if there is a check and an intact seal.

For Mijia models 1S And now there is another possibility - remote diagnosis through the Mi Home app:

1. Go to the Device Settings → Diagnostics.
2. Select Check for Errors – the application will scan the vacuum cleaner and give recommendations.
3. If available, click Correct automatically.

⚠️ Warning: If the vacuum cleaner is making a continuous high sound and does not respond to buttons, it is a sign of a jammed motor or a foreign object hitting the fan. Do not try to disassemble the device yourself.

In rare cases, the problem may be related to regional restrictions, such as some Xiaomi models purchased in China, which may block features when used outside of Asia, in which case, changing the region in the Mi Home app (Region setting in profile) will help.

💡

If the vacuum cleaner stopped responding to commands after a fall or impact, a reboot is unlikely to help, most likely a gyroscope or collision sensor is damaged, in which case a replacement module is required, which is better entrusted to the professionals.
