Perhaps your Mi Robot Vacuum started to glittle after a firmware update, stopped connecting to the Mi Home app, or you just want to sell the device and delete all personal data. In this article, we’ll break down all types of resets, from soft reboot to full zero to factory settings, including hidden methods for error models.

It is important to understand that the discharge procedure differs depending on the vacuum cleaner model (Mi Robot Vacuum-Mop 2 Pro, Viomi). V3, Dreame D9 And so on, firmware versions, and even the region of purchase, like the Chinese market (CN) We have compiled the current instructions for 2026, given the latest updates to the Mi Home and Mi Home Lite ecosystem.

If your vacuum cleaner is getting stuck, doesn't respond to buttons, or it's an Error 10 (a sensor problem), reset is often the only solution, but before you start, check that maybe the problem is a basic thing -- a dead battery, a clogged dust collector, or a poor Wi-Fi connection. In this article, you'll find a checklist for diagnostics before reset.

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

Resetting is not a universal solution, and it should not be used in vain. Here are the specific cases where the procedure is justified:

• 🔄 The vacuum cleaner does not connect to the Mi Home app after changing the router or updating the firmware.
• 🚫 Errors like Error 5 (wheel problem), Error 14 (jammed fan) or Error 18 (laser rangefinder malfunction) that are not fixed by restarting.
• 🔒 The device is tied to someone else’s account (for example, after buying a used one).
• 📱 The app shows an incorrect map or a vacuum cleaner "forgets" saved cleaning areas.
• 🔋 The battery quickly discharges after the software update (sometimes the reset restores the factory power consumption settings).

If the vacuum cleaner simply does not turn on, first check:

• ⚡ Charger and cable (try charging from another power supply).
• 🔋 Contacts at the docking station - they could have oxidized.
• 🛠️ The switch on button (sometimes it sticks due to dust ingress).

If the button doesn’t respond, try:
