How to reset the settings of the robot vacuum cleaner Xiaomi Mijia G1

Smart homeowners often face situations where the device is malfunctioning or refuses to connect to the network. Xiaomi Mijia G1 is no exception to the rule. Sometimes a software failure requires user intervention to restore the normal operation of the system.

There are several reasons why you might need a Hard Reset or a full return to factory settings, such as selling a device, moving to a new home with a different Wi-Fi network, or a critical error in navigation algorithms.

Before you start any manipulation, it's important to understand the difference between a reboot and a full reset. Reboot just shuts down and turns on the system, storing all your data. Reset removes the maps of the premises, the history of cleaning and network settings. Be careful when choosing a method.

When a complete reset of the device is required

It's not always worth resorting to drastic measures immediately after the first problem occurs, but there are clear symptoms that indicate a need to clear the memory. If the Mijia G1 stopped responding to commands from the Mi Home app, that's the first bell.

Often the problem is changing the router parameters, so if you change your ISP, your Wi-Fi password, or your network frequency, the robot will have to re-authenticate, and in such cases, the old connection profile prevents you from establishing a new link.

⚠️ Warning: Before performing a full reset, make sure you have access to the Mi Account account to which the device was linked. Once reset, the peg may fly off and you will need to re-authorize.

Also, the reset is necessary if you plan to transfer the vacuum cleaner to another owner, personal data, maps of the apartment and schedules must be deleted, and it is not only a matter of convenience, but also the digital security of your home.

Preparation for the recovery procedure

To make the process successful and without damaging the electronics, you need to perform a number of preliminary steps: first of all, make sure that the battery is charged at least 20-30%.

Find a charging station and install the Xiaomi Mijia G1 on it. Stable power is critical, because the device can reboot several times during the reset process. If the charge is lost at a critical moment, the robot can go into a cyclical reboot.

The mechanical reset button (if any in your revision) or key combinations should be pressed clearly. If the buttons are stuck with moisture or dust, it is better to postpone the procedure until cleaning.

The method of soft reset through the Mi Home app

The safest and easiest way to bring a device back to life is to use software controls, which don't delete all data permanently, but restart the network modules and reset the logic errors.

Open the Mi Home app on your smartphone. Find your robot vacuum cleaner on the device list. Click on the three-dot icon at the top right of the screen to get into the optional settings menu.

In the menu that opens, find the partition that controls the device, and it can be called "Unbind" or "Delete Device" and confirm the action, and then it will go back to standby mode.

• 📱 Open the Mi Home app and select your robot.
• ⚙️ Go to the device settings (three dots on the right at the top).
• 🗑️ Select the option to remove the device or detachment.
• 🔄 Wait for the beep and flashing indicators.

Once this is done, the robot vacuum cleaner will go into a standby mode, equivalent to a soft reset that solves 80 percent of the problems with connecting to the new Wi-Fi network.

💡

If the app says “Device Offline”, try to turn off the robot first with the power button, wait 10 seconds and turn it on again, then repeat the removal procedure.

Hardware reset buttons (Hard Reset)

If software methods don't work, you have to use physical buttons on the body. For the Mijia G1 model (often known as STYTJ01ZHM), the procedure may differ depending on the firmware version, but the basic algorithm is the same.

The top panel of the device has two main buttons: power on and start cleaning (or return to base).To perform the reset, you need to press and hold both buttons simultaneously for 5-10 seconds.

Press: [On button] + [Clean button]


Holding time: 5-10 seconds




Indication: Voice message or flashing of all lamps

Some revisions may require the use of a hidden Reset button, which is often located under the dust compartment lid or next to the wheels, and you will need a thin object, such as a paper clip, to press.

⚠️ Note: Do not use excessive force when pressing buttons. The mechanism of the buttons in smart vacuum cleaners is quite fragile and is designed for easy finger touch, not for effort when using tools.

After the combination is successfully completed, you will hear a voice message in English or Chinese confirming the reset. The Wi-Fi indicator will flash quickly, signaling readiness for pairing.

Comparison of discharge methods and their effects

Users often confuse different types of reboots, which leads to the nervous deletion of important data. Let's look at the differences between simply turning off, rebooting the network, and completely resetting the factory.

As you can see from the table, Hard Reset is the most profound intervention without flashing. It cleans the memory partition where user configurations are stored. The room map that the laser ranger (LDS) was building will also be removed.

If you just changed the router, but the model and the name of the network remain the same, you may not need to completely reset the device, just untie the device in the application and add it again as new.

💡

A full reset with buttons removes the room map and all user settings, returning the robot to the “out of the box” state.

Setup of the device after reset

Once the reset procedure is successfully completed, the robot vacuum cleaner goes into standby mode, the network indicator starts flashing, inviting the user to begin the pairing process, which is a critical stage that requires attention.

Make sure your smartphone is connected to a 2.4GHz Wi-Fi network. Xiaomi smart devices, including the Mijia G1, typically don't support 5GHz networks for initial setup. If you have a dual-band router, temporarily disable 5GHz or split networks.

In the Mi Home app, click "+" to add a device. Search may take some time. If the automatic search fails, manually select the device from the "Vacuum & Mop" list. Follow the instructions on the screen to enter the Wi-Fi password.

• 📶 Make sure your phone is connected to 2.4GHz Wi-Fi.
• 📍 Allow the application to access geolocation (GPS).
• 🏠 Select the server region corresponding to your account.
• 🔌 Enter the password from the wireless network carefully, observing the register.

During the setup, the robot can change the status of the indicators several times, do not interrupt the process and keep the phone next to the device.

Frequent problems and their solution

Even if you follow the instructions strictly, there can be unforeseen difficulties, one of the most common being the Time Out error, often associated with router locking ports or security settings.

Try temporarily disabling address layout (MAC filtering) on the router. Also make sure there are no active networks VPN-Connections on a smartphone that can redirect traffic to local devices.

If the Xiaomi Mijia G1 robot vacuum cleaner makes strange sounds or reports a sensor error after a reset, check the cleanliness of the optical sensors. The reset does not cause physical contamination that can interfere with navigation.

⚠️ Note: If after multiple attempts to reset the device continues to behave inadequately, it may be the hardware part that is the problem, for example, a malfunction of the Wi-Fi module or motherboard.

In rare cases, a cold start helps: leave the robot off for a few hours so that the capacitors are completely discharged, and then repeat the reset procedure, which helps remove the residual charge from the control logic.
