How to restart the robot vacuum cleaner Xiaomi: from a soft reboot to a complete reset

Xiaomi’s robot vacuum cleaners (including the Mi Robot Vacuum, Dreame, and Viomi models) are smart devices that make cleaning easier but sometimes require restarting. Hangings, map errors, Wi-Fi connection problems, or inadequate behavior (such as chaotic movement around the room) are all signals that the device needs a reboot, but not everyone knows that the wrong reboot can exacerbate the problem, especially if it is a factory reset.

In this article, we will discuss all ways to restart – from a simple button reboot to a deep reset through the engineering menu. You will learn how to distinguish a soft rebuke (without data loss) from a hard reset (with deleting cards, Wi-Fi settings and schedules), as well as what to do if the vacuum cleaner does not respond to buttons or is stuck in firmware update mode. Instructions are relevant for models 2018-2026, including Xiaomi Mi Robot Vacuum-Mop 2 Pro, Dreame D9 viomi V3.

1.When do you need to restart Xiaomi robot vacuum cleaner?

Not every problem requires a reboot, for example, if a vacuum cleaner doesn't return to base because of an obstacle, remove the interference, but there are symptoms where rebut is the first step of diagnosis.

• 🔄 The vacuum cleaner hangs in one place for more than 5 minutes, makes repeated sounds or flashes red.
• 📡 Not connecting to Mi. Home/Dreamehome despite the fact that Wi-Fi is working (the indicator flashes orange).
• 🗺️ Maps of premises are knocked down or the vacuum cleaner begins cleaning in a random place, ignoring the zones.
• ⚡ After updating the firmware, the device does not turn on or behaves unstable.
• 🔋 Battery discharges too quickly (possible calibration failure of the battery).

If the Xiaomi vacuum cleaner simply doesn’t respond to commands from the app, check first:

• 📱 Is the Mi Home app (or Dreamehome for Dreame devices) updated).
• 🌐 Is there access to the Internet (vacuum cleaner can be offline, but work in local mode).
• 🔌 Battery charged (at a level below 20%, some functions are blocked).

⚠️ Warning: If the vacuum cleaner is continuously squeaking or flashing red and green at the same time, this may indicate a hardware malfunction (jammed motor, sensor breakdown.

2. Soft reboot (reboot) - the safest way

Soft restart is like a smartphone reboot: all settings and maps are saved, and temporary software failures are eliminated, a method that works 80 percent of the time and takes less than a minute.

Instructions for all models Xiaomi/Dreame/Viomi:

1. Find the power button on the vacuum cleaner body (usually located on the side or on top, under the cover).
2. Hold it for 5-10 seconds until you hear the beep (or until the light flashes blue).
3. Release the button - the vacuum cleaner will turn off and then automatically switch on again.

For models with a touch button (for example, Xiaomi Mi Robot Vacuum-Mop P):

• Touch the sensor and hold for 10-15 seconds until the reboot animation appears.

Make sure the vacuum cleaner is not on charge (unplug from base)

Check the battery power (minimum 30%)

Remove the vacuum cleaner from the cleaning area (so as not to interfere)

Wait 1-2 minutes after rebooting before connecting to the application-->

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

1. Remove the device from the Mi Home app and add it again.
2. Reboot the router (sometimes Xiaomi vacuum cleaners conflict with dual-band networks).
3. Manually specify static IP vacuum cleaner in router settings.

⚠️ Attention: After a soft reboot Dreame D9 viomi V3 They may temporarily forget the current map of the room. Don't worry, after the next cleaning, it will recover.

3 Hard Reset – When a soft rebate does not help

Hard reset returns the vacuum cleaner to factory settings, removing:

• 🗺️ All saved room maps.
• 📡 Wi-Fi settings and binding to your Mi Home account.
• ⏰ Cleaning schedule and no-go zones.
• 🔊 Voice Packages and Regional Settings.

This method is used only if:

• The vacuum cleaner does not respond to a soft reboot.
• There was a firmware failure (for example, after an interrupted update).
• The device does not connect to the application despite repeated attempts.

Hard-dumping instructions:

1. Turn off the vacuum cleaner (hold the power button for 5 seconds).
2. Press the power button and the Home (or Spot Clean) button at the same time. 10–15 For the Xiaomi Mi Robot Vacuum 1S/2: hold on to food + Spot Clean. For Dreame. D9/D10: Nutrition + Home for Viomi. V2/V3: Nutrition + suction-button.

The vacuum cleaner will restart and return to factory settings (the orange indicator will light up when you first turn on).

After discharge:

• 📱 Link the vacuum cleaner to your Mi Home account again (instructions in the application).
• 🗺️ Start cleaning to create a new room map.
• ⚙️ Set up a schedule and no-go zones.

4.Reboot through the Engineering Menu (for advanced)

Some Xiaomi models (e.g. Mi Robot Vacuum 2 or Dreame) Z10 Pros have a hidden engineering menu through which you can reset the settings without losing cards or reflash the device manually. This method is risky - the wrong actions can "brick" the vacuum cleaner.

How to enter the engineering menu:

1. Turn off the vacuum cleaner.
2. Squeeze the power. + Home + Spot Clean at the same time.
3. Hold for 10 seconds until you hear a double beep.
4. Release the buttons - the vacuum cleaner will turn on in diagnostic mode (the indicator flashes green and red).

The engineering menu can:

• 🔄 Reset only Wi-Fi settings (without deleting cards).
• 📥 Fly the vacuum cleaner through USB-OTG (need a firmware file).
• 🔋 Calibrate the battery (if the battery is quickly discharged).

💡

Before entering the engineering menu, take a picture of all the current settings in the Mi Home app, which will help you quickly restore the schedule and zones after resetting.

How to get out of the engineering menu:

• Press and hold the power button for 5 seconds.
• Or wait for the automatic exit (after 2 minutes of inactivity).

⚠️ Note: In the engineering menu Dreame D9 There's a Format Flash option, which is activating it completely erases the memory of the device, including the service data. Without special software, the vacuum cleaner will become inoperable!

5.Reboot after firmware failure

If the Xiaomi vacuum cleaner is getting stuck during the upgrade (blinks blue and doesn’t respond to buttons), try:

1. Forced reboot: Disconnect the vacuum cleaner from the charging base. Press the power button for 20 seconds. Connect to the base and wait for automatic recovery.
2. Manual update through USB (support-model OTG): Download the firmware for your model from the official website mi.com. Unpack the archive and place the.pkg file on the flash drive. FAT32. Connect the flash drive to the vacuum cleaner through USB-OTG Adapter, hold power. + Home for 10 seconds – the update will begin.

If the firmware is critically damaged, the vacuum cleaner can:

• 🔴 Blink red and emit intermittent signals.
• 📵 Do not turn on despite charging.
• 🗣️ Pronounce a voice message in Chinese ("" - "system error").

In this case:

• Contact the Xiaomi Service Center (if warranty is valid).
• Or try to re-flash through STISP (Requires a soldering iron and experience with electronics).

💡

Never interrupt the firmware update process! If the vacuum cleaner flashes blue, it means that the data is written to the flash memory, and the power outage at this point will lead to a complete loss of performance.

6. Frequent mistakes and how to avoid them

Many users make problems worse by rebooting incorrectly, and consider common mistakes:

• ❌ Reset via app: Mi Home has a "Reset settings" option, but it's unstable, often after that the vacuum cleaner doesn't connect back to Wi-Fi.
• ❌ Use of informal firmware: Forum firmware (e.g. Xiaomi Vacuum Hack) can add new features, but often breaks the laser rangefinder or navigation system.
• ❌ Restart during cleaning: If you interrupt the Dreame or Viomi vacuum cleaner while washing the floors, the water may remain in the system, which will lead to corrosion of contacts.

How right is it?

• ✅ Before resetting, disconnect the vacuum cleaner from the base - this will prevent conflicts with the charging module.
• ✅ Use only official firmware from mi.com or dreame.tech.
• ✅ After a hard reset, don’t connect the vacuum cleaner to Wi-Fi right away – give it 5 minutes to initialize.

7. Prevention: how to reduce the number of failures

To ensure that the Xiaomi vacuum cleaner works stably:

• 🔋 Calibrate the battery every 3 months: Discharge the vacuum cleaner to 0% (until it turns off). Charge to 100% without interruption. Repeat the cycle 2-3 times.

Update the firmware

Clean the sensors.

• Laser rangefinder (wipe with a soft cloth).
• Infrared sensors (use a cotton swab).
• Charging base contacts (clean from oxidation).

Do not use beta versions.

Mi Home

If the vacuum cleaner has started to hang often, check:

• 🔌 Base power supply unit – a faulty adapter can cause malfunctions.
• 📶 Wi-Fi signal level at the cleaning site (if weak, the vacuum cleaner loses communication).
• 🧲 Magnetic fields – do not place a base near microwaves or speakers.

💡

Regular cleaning of the side brush and main shaft prevents overheating of the engine - one of the main reasons for accidental reboots.
