How to reset Xiaomi brush to factory settings: all ways

Why You Might Need to Reset Xiaomi Smart Brush

Xiaomi’s smart brushes (such as Mi Electric Toothbrush, Mi Oral Irrigator or Mi Smart Toothbrush T300/T500/T700) may not work properly over time: hang, not sync with the Mi Home app, show incorrect cleaning statistics or refuse to turn on. In 80% of these cases, a factory reset helps – a procedure that erases all user data and returns the device to its original state.

The reasons for resetting range from the banal (you sell a brush and want to remove the binding to your account) to the technical (firmware failure after an update or conflict with other devices in the Xiaomi ecosystem). It is important to understand that reset is not a panacea, but a diagnostic tool. If the problem is caused by a mechanical failure (for example, a malfunction of the motor or battery), software reboot will not help.

In this article, we will discuss all the official reset methods for different Xiaomi brush models, including hidden button combinations that are not described in the manual, and you will learn how to avoid typical errors that can cause a reset to fail.

Preparation for resetting: what to do in advance

Before you start resetting, follow a few mandatory steps that will save you from losing data and help you avoid problems with reconfiguring the device.

• 📱 Remove the brush from the Mi Home app. After the reset, the device will automatically unplug from the account, but it is better to do it manually: go to Profile → My devices, find the brush and click "Delete».
• 🔋 Charge the brush to at least 30% Reset at low charge can cause firmware failure, especially on models T500 and T700 coloured.

⚠️ Note: If the Xiaomi brush doesn’t turn on or respond to buttons, resetting via the key combination may not work.In this case, first try forced reboot: connect the device to charging and hold the power button for 15-20 seconds.

In the models with OLED-display (e.g. Mi Smart Toothbrush) T700) Before reset, it is recommended to update the firmware to the latest version:

1. Open Mi Home and go to the brush settings.
2. Select firmware update (if the item is missing, your version is up to date).
3. Wait until the process is complete (don’t turn off Bluetooth!).

💡

If the brush is not updated via Mi Home, try reconnecting it to the app: remove the device, restart the smartphone and add the brush again.

Method 1: Reset via Mi Home (official method)

The safest and most recommended way is to use the branded Mi Home app, which is suitable for all Xiaomi brush models except the earliest versions (e.g. Mi Electric Toothbrush 1, Released in 2016).

Instructions:

1. Open Mi Home and go to the section with your brush.
2. Press three points (⋮) in the upper right corner and select Device Settings.
3. Scroll down and find Reset to factory settings (or Delete Device on some versions of the app).
4. Confirm the action. The brush will reset and its indicator will flash red (on models with the display will appear the inscription Reset).

• In the main menu of the brush in Mi Home, click on the gear icon (⚙️).
• Select Additional → Reset the settings.

Method 2: Hardware button reset (for all models)

If the brush doesn’t connect to the Mi Home or the app doesn’t see the device, use a hardware reset via a button combination.This method works on all models, including the Mi Electric Toothbrush T300/T500/T700 and Mi Oral Irrigator.

2. Press and hold the power button for 10 seconds until the indicator starts flashing red and green alternately.
3. Release the button. The brush will reset and return to factory settings.

Instructions for display brushes (e.g. T700):

1. Hold the power button for 15 seconds until Factory Reset appears on the screen.
2. Confirm the reset by pressing the button again (some firmware will need to hold it for 3 seconds).
3. Wait for the reboot. The display will display a welcome message.

On the Mi Smart Toothbrush T700 with firmware below version 1.4.7, the hardware reset may not work the first time. Repeat the procedure 2-3 times at 30 seconds intervals.

Method 3: Reset via Xiaomi Home (for Chinese firmware)

If your Xiaomi brush is bought in China or has Chinese firmware, the standard Mi Home app may not see it.

Step-by-step:

1. Download Xiaomi Home from APKPure (the official Google Play store can block installation).
2. Sign in with the same account as you do on Mi Home.
3. Add the brush manually: press + → Add the device → Toothbrush.
4. After connecting, go to the device settings and select Reset to factory.

• 📌 Make sure that the smartphone is enabled developer mode and debugging USB (Sometimes it helps when connecting devices with Chinese firmware).

1. Turn on the brush and place it with a brush up on a flat surface.
2. Hold the power button for 5 seconds until Calibration appears on the screen.
3. Wait until the process is completed (about 10 seconds).

If the brush does not save settings after resetting (for example, resets the cleaning mode after turning off), check:
