Smart tech owners often face situations where the device is incorrect, loses connection to the router or freezes during tasks. In such cases, the most effective solution is to completely reset the settings to factory parameters. This action removes all user data, room maps and cleaning history, returning the gadget to its original state. For Xiaomi models with wet cleaning function, this procedure has its technical nuances that must be considered so as not to damage the software.
Hard Reset may be required when selling a device, transferring it to another user, or persistent errors that are not eliminated by a normal reboot. It is important to understand that after this operation, the robot will forget all learned routes and require reconfiguration through the Mi Home or Xiaomi Home application. Below we will discuss in detail the algorithms for different series of devices, taking into account the design of the control buttons.
Before you start taking drastic measures, make sure that the problem is not solved by simply turning off the power or updating the firmware. However, if you have already made a final decision, you need to prepare the device itself: remove the wet cleaning module, if it is installed, and make sure that the battery is at least 50% charged, which is critical, since interrupting the reset process due to discharge can lead to a software failure of the controller.
When you need a complete reset of settings
The main indication for the factory reset procedure is that the software is incorrect, which can be manifested in persistent Wi-Fi connection errors even when the router is working properly, or in the chaotic behavior of the robot during cleaning. Sometimes the device stops responding to commands from the application, and the status of "Online" changes to "Offline" for no apparent reason.
Also, a complete reset is mandatory when you change the owner of the equipment, and the robot's memory stores data about your network, schedule and even voice packets if you used voice control, so that the new user can customize the device for himself, you need to completely clear the internal memory from previous configurations.
⚠️ Warning: Resetting permanently removes stored maps of the room. If you used the zoning mapping function, you'll have to retrace the entire route to create a new map.
In rare cases, a reset is required after a failed firmware update when the system is unstable. If after the upgrade, the robot begins to make more mistakes or lose contact with the sensors, returning to the factory state can help eliminate software conflicts.
Preparation for the discharge procedure
The first step in preparation is to physically prepare the device itself, flip the robot vacuum cleaner over and inspect the bottom of it, and if the device has a wet cleaning module (water tank and cloth), it must be removed, to prevent the contacts from getting moisture accidentally during manipulation, and also to make certain buttons available if they are located at the bottom.
Make sure the robot is in a Wi-Fi signal receiving zone, although the reset process itself does not require internet, it will be needed immediately after reconfiguring. Also check the condition of the side brush and main roller: if they are heavily contaminated, it is better to clean them before reset, so that after setting up the device immediately works efficiently.
Make sure you remember the password from your Wi-Fi network beforehand, as after resetting, the robot will see itself as a new device. If you use a dual-band router, make sure the phone is connected to a 2.4GHz network, as most Xiaomi models do not support 5GHz frequency for control.

Take a screenshot of the current cleaning schedule settings in the app before resetting, which will help you quickly restore the robot’s convenient schedule after resetting.
Reset algorithm for single-button models (Series 1, S50, S55)
The first generation models and popular versions of the S50/S55 have a control panel with minimal elements, which uses a combination of buttons to enter reset mode, usually by simultaneously pressing the on and back buttons to the base (home).
The process is this: turn on the robot vacuum cleaner, wait for the system to start. Then press and hold both buttons simultaneously for 5-10 seconds. Indicators can flash, and the voice module will tell you when a reset or reboot has begun. Some firmware versions require you to hold the buttons to a characteristic beep.
Once the device has signaled or voiced a reset, release the buttons. The robot will reboot automatically. If that hasn't happened, manually turn it off with the power button and turn it on again. Now the device is ready to search for the Wi-Fi network.
☑️ Checklist reset with one button
Resetting settings on models with display and touch control
More modern models such as Xiaomi Vacuum Mop 2 Pro+ or Dreame (Xiaomi ecosystem), often equipped with touch panels or OLED-The resetting mechanics may be different here. In some cases, you only need to press the switch on the switch. 10-15 seconds until the menu appears on the screen or the indicator starts flashing orange.
For devices with full touch interfaces on the case (which is rare, but happens in top models), reset can be done through the settings menu on the device itself, if it is available. However, the classic method of hard reset by pressing the buttons remains the main one.
Special attention should be paid to the Mijia 1C or G1 series models, where the power button can be hidden or combined with an indicator, in such cases, the retention duration can be up to 15 seconds. If the standard combinations do not work, refer to the specification of the particular model, as the logic of the controller may vary.
| Model of the device | Button combination | Retention time | Indication |
|---|---|---|---|
| Xiaomi Vacuum 1 / S50 | Power + Home | 5-10 seconds | Voice message |
| Mijia 1C / G1 | Power (long-term) | 10-15 sec. | Blinking of the indicator |
| Xiaomi Vacuum Mop Essential | Power + Spot | 5 seconds | Sound signal |
| Dreame D9 / F9 | Power + Home | 5 seconds | Wi-Fi reset |
Setting up the Wi-Fi module after resetting
After successfully performing the reset procedure, the robot vacuum cleaner enters pairing mode. The Wi-Fi indicator starts flashing, signaling readiness for connection. At this stage, the old network data is deleted, and the device creates its access point or waits for connection through the application.
Open the Mi Home app on your smartphone. Click the plus in the top right to add a new device. The app will automatically scan the network and should find your robot vacuum cleaner. If the automatic search fails, manually select the model from the list.
Follow the instructions on the screen: select your Wi-Fi network, enter a password. Hold your phone close to the robot (at 20-30 cm) The data transfer process can take from 30 seconds to 2 minutes.
⚠️ Warning: Make sure that geolocation is enabled on your smartphone (GPS) Without permission to access the geolocation, the application will not be able to correctly transfer data about the Wi-Fi network to the robot vacuum cleaner.
If the connection fails the first time, try to turn off mobile Internet (4G/5G) on your phone, leaving only Wi-Fi. Sometimes the smartphone tries to use the mobile network to transfer data, which interrupts the process of setting up the local device.
What if the robot is not visible in the app?
Removing common errors after resetting
Often, after returning to the factory settings, users encounter an error “Device has already been added”, which means that Xiaomi servers remember the binding of this serial number to your account, in which case, find the device in the list in the application, delete it (basket icon or gear -> Delete), and only then try to connect again.
Another common problem is that the robot is plugging in, but it's offline, which could indicate a weak signal at the charging point or a conflict. IP-Try rebooting the router and re-launching the robot, and check if the router is blocking new devices (MAC-filtering).
If a wet-cleaning robot stopped dispensing water properly after reset, you may need to calibrate the pump. The app often has a water-level adjustment or pump test feature, run it to make sure that the software reset is not a physical water-supply control.
💡
Removing the device from the list in the app before re-addition is a must if you get an error that the device is already occupied.
