Xiaomi Robot Vacuum S1 with wet cleaning is one of the most popular devices for automated cleaning. However, even the most reliable equipment sometimes requires rebooting: after software failures, freezes or sensors malfunction. Unlike conventional vacuum cleaners, wet cleaning models have additional modules (for example, a water tank and a pump), which complicates the reset process.
In this article, we will discuss all possible ways to reboot the Xiaomi S1, from a soft restart to a full reset to factory settings. We will pay special attention to the nuances associated with the wet cleaning system, since improper actions can lead to leaks or damage to the pump. If your vacuum cleaner has stopped responding to commands, gives errors like E10 or E12, or simply works unstablely, the following instructions will help bring it back to life.
When you need to restart the robot vacuum cleaner Xiaomi S1
Not every problem requires a complete reset. Before you start taking drastic measures, determine if your Xiaomi Robot Vacuum S1 really needs a reboot.
- 🔄 The vacuum cleaner hovers in one place and does not respond to buttons or commands from the Mi Home app.
- ⚠️ Errors appear on the display or in the application (for example, E01, E05, E10), which do not disappear after cleaning the sensors.
- 📱 The device does not connect to Wi-Fi or constantly loses communication despite stable Internet connection.
- 💧 The wet cleaning system does not spray water or, conversely, pours it without stopping.
- 🔋 Battery discharges too quickly (less than 30 minutes of operation), although it used to hold the charge longer.
If at least one of these symptoms is on the rise, a soft or hard reboot can help, but there are also false alarms, like if the vacuum cleaner doesn't return to base, first check if something is blocking the path (wires, high-pile carpets) or if the base battery is running out. And E02 often means just dirty side brushes - you just need to clean them.
⚠️ Warning: If the vacuum cleaner makes uncharacteristic sounds (screaming, knocking) or smells of a burn, rebooting won't help - it's a mechanical breakdown.
Soft reboot (restart) Xiaomi Robot Vacuum S1
The most gentle method, which does not affect the settings and saved maps of the premises, a soft restart helps with temporary software failures when the vacuum cleaner is getting stuck but physically healthy, the procedure takes less than a minute and does not require disassembly.
Here's how to do it:
- Press and hold the power button on the vacuum cleaner for 10-15 seconds until you hear the beep (or until the indicator starts flashing).
- Release the button. The vacuum cleaner will turn off.
- Wait 30 seconds – that’s enough time for the capacitors to run out.
- Press the power button to turn the device on.
After restart, check the vacuum cleaner. If the problem was a temporary failure, it should work normally. If the soft reboot did not help, move on to the next method.

Hard reset (forced reset)
If a soft restart doesn't work, you'll need a hard reboot, which resets the current session, but doesn't affect the saved settings (maps, schedules), which is often confused with a full factory reset, but these are different procedures.
For the Xiaomi Robot Vacuum S1, the hard reboot is performed through a hidden button combination:
- Turn off the vacuum cleaner (hold the power button for 5 seconds until it shuts down).
- Press and hold the power button and the home button (with the image of the house) at the same time.
- Keep them tight for 10-12 seconds until the double signal is heard.
- Release the buttons. The vacuum cleaner will start rebooting (the indicator will flash orange).
After a hard reboot, the vacuum cleaner can recalibrate the sensors, which is normal. Let it complete the process (usually takes 1-2 minutes).
- 🔌 Battery charge (if the charge is below 20%, some functions may be blocked).
- 📶 Wi-Fi connection (vacuum cleaner could "forget" network after resetting).
- 💧 Water tank condition (if not installed correctly, wet cleaning system is not activated).
⚠️ Warning: Do not interrupt the reboot process, even if the vacuum cleaner does not react for a long time.Forced power outage during sensor calibration can lead to loss of the room map.
Reset to factory settings: when and how to do
A complete reset is a last resort that erases all data: stored maps, cleaning schedules, wet cleaning settings and Wi-Fi connectivity.
- 🔄 Vacuum cleaner doesn't respond to any commands after soft and hard reboot.
- 📱 You plan to sell or transfer the device to another user.
- 🛠️ There was a major firmware failure (for example, after a failed update).
To reset to factory settings on the Xiaomi Robot Vacuum S1 there are two ways: through the buttons on the case and through the Mi Home app.
Method 1: Hardware reset (buttons)
- Turn off the vacuum cleaner (hold the power button for 5 seconds).
- Press and hold the home button for 10 seconds, then, without letting it go, briefly press the power button.
- Hold the Home button for another 5 seconds until a long signal (3-4 seconds) is heard.
- Release the button. The vacuum cleaner will start the reset process (the indicator will flash white and orange).
Method 2: Reset via the Mi Home app
- Open the Mi Home app and go to the vacuum cleaner settings.
- Select Settings → About the device → Resetting settings.
- Confirm the action (you may need to enter a password from your Xiaomi account).
After the vacuum is completely discharged, you'll return to the "out of the box" state.
- 📱 Reconnect it to Wi-Fi.
- 🗺️ Create a new map of the premises.
- 💧 Set up wet cleaning parameters (spray intensity, cleaning areas).
What happens if you interrupt the discharge?
Features of reboot in case of problems with wet cleaning
The wet cleaning system in the Xiaomi Robot Vacuum S1 is the most vulnerable module. If the vacuum cleaner does not spray water correctly (or at all), a conventional reboot may not help.
| Problem. | Possible cause | Decision |
|---|---|---|
| No spraying. | Clogged filter pump or tube | Wash the system under running water, clean the spray hole with a needle |
| It's always pouring water. | Failed water level sensor or valve | Reset the wet cleaning settings in Mi Home or make a full reset |
| E10 error (reservoir problem) | Incorrect installation of the tank or leak | Reinstall the tank, check the sealing gums |
| E12 error (pump) | Stifling the system or blocking the pump | Remove the tank, shake it, then reload the vacuum cleaner |
If you have a problem after checking these items, perform a hard reboot (described above). If that doesn't work, reset the wet cleaning settings separately:
- In the Mi Home app, go to Cleaning Settings → Wet Cleaning.
- Select Reset Spray Settings.
- Set the parameters again (recommended intensity for laminate - Average).
💡
After resetting the wet cleaning settings, perform a test cleaning on a small area to make sure the pump is working properly.
Frequent Reboot Errors and How to Avoid Them
Many users make mistakes that, instead of solving the problem, make it worse.
- 🔌 Shutting down the power during the reset can kill the firmware. Always wait until the process is complete (the indicator will stop blinking).
- 💦 Reboot with full water tank - when discharged, the pump can unpredictably work.Always drain the water before any reboot.
- 📱 Use outdated Mi Home – some reset features are only available in the latest versions of the app.
- 🔋 Ignoring the charge level – if the battery is discharged below 30%, the reset may be incorrect.
Another common mistake is the confusion between the models: The instructions for the Xiaomi Robot Vacuum S1 are not suitable for the Xiaomi Mi Robot Vacuum-Mop P or Viomi V3. Make sure you follow the manual specifically for your model (check the name on the sticker under the vacuum cleaner cover).
⚠️ Note: If the vacuum cleaner gives an error E04 (problem with the gyroscope, don't try to calibrate it yourself. It requires special equipment - contact the service.
Alternative methods of problem-solving
If the reboot didn't work, maybe the problem is deeper. Here's what you can try before you go to the service:
- 🔄 Firmware Update: Go to Mi Home → Settings of the device → Firmware update. Make sure the vacuum cleaner has the latest version of the software. Sometimes bugs are fixed with updates.
- 📡 Wi-Fi Network Reset: Remove the vacuum cleaner from the network in Mi Home (Settings) → Remove the device, then reconnect it. Use the 2.4 GHz access point - 5 GHz is not supported.
- 🔧 Manual sensor calibration: Place the vacuum cleaner on a flat surface, press and hold the Home button for 5 seconds until you hear the signal. This will trigger the calibration of the gyroscope and the obstacle sensors.
If the vacuum cleaner is still not working, check the status of the battery.
- Turn over the vacuum cleaner and remove the battery compartment cover (a T5 screwdriver will be required).
- Check if there's any swelling on the battery, and if there's any, it needs to be replaced immediately.
- Measure the voltage with a multimeter (the norm for Xiaomi S1 is 14.4-14.8 V at full charge).
💡
Before disassembling the vacuum cleaner, turn off the battery to avoid short circuits. If you are not sure of your skills, trust the diagnosis to a specialist.
