How to reset system parameters on the Xiaomi robot vacuum cleaner: the complete guide

Xiaomi’s robot vacuum cleaners are smart devices that accumulate setup errors over time, lose touch with the app, or start to malfunction. Resetting to factory settings is a universal solution for most software problems, from cleaning card failures to the inability to connect to the Mi Home. But how to properly perform this procedure so as not to aggravate the situation?

In this article, we will discuss all the current reset methods for Mi Robot Vacuum, Dreame and Viomi models (including the new versions of 2023-2026), explain when to soft reset (without losing cards), and when to complete (with deleting all data), and warn against typical errors that can turn a vacuum cleaner into a “brick”.

When do I need to reset the robot vacuum cleaner settings?

Resetting the system is not the first mistake, but only when other methods have failed, and here are the key symptoms that indicate the need for the procedure:

• 🔄 Vacuum Cannot Connect to Wi-Fi or Mi Home App Despite Correct Password and Router Restart.
• 🗺️ The device does not save a map of the room, every time starts cleaning from scratch or draws chaotic routes.
• ⚠️ Errors with codes are constantly appearing (for example, 10-12, 5-2, 2-3), which are not removed by cleaning the sensors.
• 🔋 After updating the firmware vacuum cleaner does not respond to commands, freezes or behaves unpredictable.
• 🏠 You sell or transfer your device to another user and want to delete all personal data.

It's important to distinguish between software failures and hardware failures, for example, if a vacuum cleaner doesn't charge or makes strange noises when driving, resetting is unlikely to help, you need to diagnose the engine or battery, but if the problem is related to Mi Home, maps or updates, resetting is often the only working solution.

⚠️ Warning: If the vacuum cleaner was linked to a Mi Account account with the device locked enabled, a reset without detachment can result in a complete lock.

Three official methods of resetting: which one to choose?

Xiaomi has developed several methods for returning to factory settings, depending on the vacuum cleaner model, application access, and the purpose of the reset (partial or full).

The most reliable way is to reset the hardware button, as it works even when the firmware is stuck, but if you have access to the Mi Home, you should use the software method, which allows you to save the maps of the premises (in some models) and avoid reconfiguration.

💡

Before reset, record or photograph the current settings in the app (cleaning modes, schedules, no-go zones) and save time for reconfiguration.

Method 1: Hardware reset via button (for all models)

It’s a versatile method that works on 99% of Xiaomi’s robot vacuum cleaners, including Mi Robot Vacuum-Mop 2, Dreame D10s and Viomi V3. The instruction is suitable even for devices that don’t turn on or respond to the app.

1. Turn off the vacuum cleaner (if it's on). To do this, press and hold the power button. ON/OFF during 3–5 seconds until the indicator goes out.
2. Find the reset button: 🔍 On most models, it is a Wi-Fi button (with an antenna icon) or a Home button (house). 🔍 On Dreame D9/D10 viomi V3 The switch button is used (held in a special mode).

Press the button.

Release the button

After resetting, the device will return to factory settings: all maps, schedules, suction settings and binding to the Mi Account will be deleted. When you first turn on, the vacuum cleaner will prompt you to reconfigure it after buying.

Make sure the vacuum cleaner is at least 20% charged

Disconnect the vacuum cleaner from the charging station

Find the reset button (Wi-Fi/Home) in the instructions for the model

Prepare a screwdriver (for some models, disassembly is required)

⚠️ Note: On the Mi Robot Vacuum X10+ dreame L10s Ultra hardware reset results in the laser rangefinder being removed, and after the procedure, you will have to manually train the vacuum cleaner to recognize obstacles (the instructions are in the official manual).

Method 2: Software reset via Mi Home

If the vacuum cleaner is connected to the application, this method is preferable – it allows you to choose the type of reset (full or partial) and save some data.

1. Open Mi Home and select your vacuum cleaner from the device list.
2. Go to Settings → General → Reset settings (or additionally → Reset on new versions).
3. Choose one of the options: 🔄 Reset cleaning settings – only removes schedules, zones and modes (maps will be saved). 🗑️ Full reset – returns all parameters to factory (including maps). 🔒 Delete the device - untie the vacuum cleaner from the account (needed for sale).

Wait for the process to be completed (the vacuum cleaner will restart and emit an audible signal).

The advantage of this method is to save the maps of the premises when choosing a partial reset, but if the vacuum cleaner "gluts" due to damaged firmware, the software reset may not work, in which case only the hardware method will help.

Method 3: Reset via service menu (for advanced users)

This is a method that is suitable for power users and is used when standard methods don't work. It involves logging into the vacuum cleaner's engineering menu through a combination of buttons. Attention: wrong actions can lead to breakdown!

Instructions for Mi Robot Vacuum 1S, Dreame D9 and Viomi V3 models:

1. Turn off the vacuum cleaner and remove it from the charging station.
2. Press the Wi-Fi button and the “Spot Cleaning” button at the same time.
3. Without releasing the buttons, turn on the vacuum cleaner (press ON/OFF for 3 seconds).
4. Hold all three buttons for 10-15 seconds until the white light light lights up and the double signal sounds.
5. Release the buttons - the vacuum cleaner will go into recovery mode.
6. To reset, select the Reset to Factory option (some models require you to press Wi-Fi 3 times in a row).
7. Set-up of maps and zones: 🗺️ Run the first cleaning in Map mode (usually activated automatically). Once completed, check the map in the app and set up the no-go zones.

If the vacuum cleaner does not connect to Wi-Fi after reset, try:

• 🔌 Restart your router (sometimes changing your Wi-Fi channel to 2.4 GHz helps).
• 📵 Make sure that the name of the network does not contain Cyrillic or special symbols.
• 🔄 Repeat the reset (probably the procedure was incorrect).

💡

After reset, be sure to update the vacuum cleaner firmware to the latest version - this will eliminate known bugs and improve the stability of the work.

Common Mistakes and How to Avoid Them

Even a simple process like resetting can go wrong, and here are some common mistakes and ways to prevent them:

If the vacuum cleaner does not save the settings after reset (for example, the schedule or suction power), check:

• 🔄 Firmware version – on older versions (below 3.5.8) there may be data saving bugs.
• 📵 Wi-Fi stability – with a weak signal, settings can be reset.
• 🔋 Battery charge – at a level below 15%, some functions are turned off.

If none of the methods worked, there may be a hardware problem (e.g., damaged device memory) in which case, contact Xiaomi’s service center – self-repair can make things worse.
