Connecting a Xiaomi robot vacuum cleaner to Wi-Fi without a password: all working methods

Connecting a robot vacuum cleaner Xiaomi Accessing your home Wi-Fi network usually requires entering a password—but what if you don't know it, forgot it, or your router is configured to secretly broadcast the SSID? There are several legal and technically sound ways to bypass this step without hacking the network. In this article, we'll look at 5 proven methods, who work on models Mi Robot Vacuum, Mi Robot Vacuum-Mop And Viomi (including versions from 2018 to 2026).

It is important to understand that all the methods described below assume that you have physical access to the router or network administrator rights. If you attempt to connect your vacuum cleaner to someone else's Wi-Fi network, this violates the law on personal data (Federal Law No. 152) and may result in liability. We only consider legitimate scenarios: restoring access to your network, using guest functions, or alternative authentication protocols.

Before you begin, make sure your robot vacuum cleaner Xiaomi supports the selected method. For example, WPS connection works only on routers with an active WPS button, and guest network must be pre-configured in the admin panel. If you are unsure of your device model, check it in the mobile app. Mi Home (chapter Devices → Settings → Information).

1. Connecting via a guest network (without a password)

The easiest and safest way is to use guest Wi-Fi network, if it's configured on your router. Guest networks often don't require a password or use simplified authentication. Here's how:

• 📶 Check for guest network availability: on most routers (for example, TP-Link, ASUS, Keenetic) the guest network has a name in the format Guest_Primary_Network_Name or Primary_Network_Name-5G_GuestTry finding it in the list of available networks on your smartphone.
• 🔧 Activate the guest network: If it is not there, go to the router control panel (usually at the address 192.168.0.1 or 192.168.1.1) and enable guest access in the section Wi-Fi → Guest Access or Wireless → Guest Network.
• 🤖 Connect the vacuum cleaner: in the app Mi Home select an item Add a device → Robot vacuum cleaner and select the guest network from the list. If the network is open, you won't need to enter a password.

Please note: the guest network may have speed limitations or access restrictions for local devices. For example, a vacuum cleaner won't be able to connect to the servers. Xiaomi for updates if outgoing traffic for guest clients is blocked in the router settings. In this case, check the settings Isolation of clients (AP Isolation) And MAC address filtering.

2. Using WPS to connect without a password

WPS (Wi-Fi Protected Setup) — is a standard that allows devices to connect to a network without entering a password. Many robot vacuum cleaner models Xiaomi (For example, Mi Robot Vacuum 1S, Mi Robot Vacuum-Mop 2) support this protocol. To use WPS:

1. Activate WPS on your router: Press the physical WPS button on the router body (usually it is labeled) or enable WPS in the web interface in the section Wi-Fi → WPSThe button should blink or light blue/green.
2. Start the connection on the vacuum cleaner: in the app Mi Home At the network selection stage, select the option Connecting via WPS (or WPS Connection). You will have 2 minutesto complete the process.
3. Wait for synchronization: The vacuum cleaner will automatically connect to the network. If the process is interrupted, try again after rebooting the router.

An important nuance: some routers (for example, Zyxel Keenetic) require entering the WPS PIN, which is located on the device's sticker. In this case, the method will not work without a password. WPS may also be disabled by default on newer router models due to security vulnerabilities.

Make sure your router supports WPS (check the documentation)

The WPS button must be physically present on the case.

Vacuum cleaner Xiaomi must be in connection standby mode (Wi-Fi indicator flashing)

Disable the VPN on your smartphone—it may be blocking local device discovery.

3. Connection via QR code (alternative method)

Some models of robotic vacuum cleaners Xiaomi (For example, Viomi V3 or Mi Robot Vacuum-Mop P) support Wi-Fi connection via QR code, which is generated by the router. This method bypasses the need to manually enter a password, but requires preliminary configuration:

• 📱 Generate a QR code: Find the section in the router control panel Wi-Fi → QR code for connection (on ASUS This AiMesh → QR Code, on TP-Link — Tether → QR Connection). Download or display the code on the screen.
• 🤖 Vacuum cleaner scanner: in the app Mi Home At the network selection stage, select the option Connection via QR code and point your smartphone's camera at the code. The vacuum cleaner will automatically receive the network data.
• ⚡ Confirmation: Wait for a message indicating a successful connection. If the connection freezes, restart the vacuum (hold the power button for 10 seconds).

This method does not work on all routers. For example, Keenetic does not support generating QR codes for Wi-Fi, but MikroTik This feature is only available in RouterOS 7+ firmware. If your router doesn't have this option, try using third-party QR code generation apps (e.g., WiFi QR Generator), but they will require you to enter the network password.

4. Connecting via a temporary password (the "forgot password" method)

If you forgot your Wi-Fi network password but have access to the router, you can temporarily reset your password or create a new one. This method doesn't require knowing the current password, but it does require physical access to the router:

1. Reset your router settings: press and hold the button Reset (It's usually recessed into the case and requires a paperclip) for 10-15 seconds until the lights start flashing. The router will reset to factory settings.
2. Set up a new network: connect to the router via cable or Wi-Fi with the factory name (for example, TP-Link_XXXX) and a password (usually indicated on a sticker). In the control panel (192.168.0.1) create a new network with a simple temporary password (eg. 12345678).
3. Connect the vacuum cleaner: in the app Mi Home Select the new network and enter the temporary password. After successfully connecting, restore your router's previous settings.

⚠️ Attention: Resetting the router will disconnect all connected devices (TVs, laptops, cameras). Before the procedure, write down the current settings or make a backup copy of the configuration in the System Tools → Backup & Restore.

An alternative option is - view the current password in the router settings. To do this:

1. Connect to the router via cable or Wi-Fi (if you are connected previously).
2. Open the Control Panel and find the section Wi-Fi → Security or Wireless → Wireless Security.
3. The password will be displayed in the field. Password, Key or Pre-Shared Key (may be hidden behind asterisks - use the "Show password" option).

5. Connect via Mi Home using a Xiaomi account

If your robot vacuum cleaner Xiaomi was previously connected to the network and linked to an account Mi Account, you can reconnect without re-entering your password. This method works if:

• 🔄 The vacuum cleaner has already been added to your account Mi Home.
• 📱 You have access to the smartphone from which the connection was previously made.
• 🌐 The router did not change the network name (SSID) or password.

Instructions:

1. Open the app Mi Home and make sure that the vacuum cleaner is displayed in the list of devices (section Devices).
2. Click on the vacuum cleaner icon and select Settings → Reset Wi-Fi (or Reset Wi-Fi).
3. Confirm the reset. The vacuum will automatically try to connect to the last network used. If the network name (SSID) hasn't changed, a password will not be required.
4. If the connection does not occur, check if the router settings have changed (for example, the encryption type with WPA2 on WPA3).

Important: This method only works if the vacuum cleaner has previously successfully connected to the network and has not been deleted from the account. If the device has been reset to factory settings (using the button) Reset on the body), the link to the account is lost.

6. Alternative methods: Hotspot and Ethernet adapter

If none of the above methods worked, consider non-standard solutions:

• 📶 Hotspot mode: Temporarily share your smartphone's internet connection, connect your vacuum cleaner to this network, and then reconfigure your router. This will help bypass the restrictions of your main Wi-Fi network.
• 🔌 Ethernet adapter for vacuum cleaner: some advanced models (for example, Xiaomi Mi Robot Vacuum-Mop 2 Pro) support connection via adapter USB-to-EthernetIn this case, a Wi-Fi password is not required, but you must configure a static IP address on your local network.
• 🔄 Firmware update: If the problem is caused by a bug in the vacuum cleaner software, connect it to a different network (for example, at a friend's house or in a cafe), update the firmware via Mi Home, and then try again at home.

Usage Ethernet adapter Requires additional equipment and network configuration skills. For example, you'll need:

1. Buy a compatible adapter (eg. USB 2.0 to Ethernet with a chip ASIX AX88772).
2. Connect it to the USB port on the vacuum cleaner (if available).
3. Set up a static IP within your local network range (e.g. 192.168.0.100 with a mask 255.255.255.0).
4. In the router, add a rule to bind the vacuum cleaner's MAC address to a dedicated IP.

⚠️ Attention: Not all models of robotic vacuum cleaners Xiaomi have a USB port or support Ethernet connection. Before purchasing an adapter, check compatibility on forums (e.g., 4PDA or Xiaomi Community).

Common mistakes and their solutions

Even if you follow the instructions correctly, problems may arise. Let's look at common errors and how to fix them:

• 🚫 "Unable to connect to the network":
  • Check if your vacuum cleaner supports the selected method (for example, older models do not work with WPS).
  • Make sure your router is not blocking new connections (option MAC Filtering should be disabled).
  • Restart the vacuum cleaner (hold the power button for 10 seconds) and try again.
• ⚠️ "Incorrect password" when connecting via WPS:
  • On some routers (for example, D-Link) WPS requires entering the PIN code from the sticker.
  • Check if WPS is disabled in the security settings (Wi-Fi → WPS → Disable).
• 🔄 The vacuum cleaner constantly disconnects from the mains:
  • Check your router's power saving settings (turn off Wi-Fi Power Save).
  • Change your Wi-Fi channel to a less crowded one (for example, with Auto on 6 or 11).
  • Update the firmware of your router and vacuum cleaner.

If none of the methods worked, check:

• 📡 Wi-Fi range: some vacuum cleaners Xiaomi work only in the range 2.4 GHz and don't see the network 5 GHz.
• 🔒 Encryption type: the vacuum cleaner may not support WPA3 - switch the router to WPA2-PSK.
• 📵 Interference: If there are many nearby networks, the vacuum cleaner may not see yours. Try temporarily disabling nearby access points.

FAQ: Answers to frequently asked questions

Is it possible to connect a Xiaomi vacuum cleaner to Wi-Fi without the Mi Home app?

No, officially connection is only possible through Mi Home or Xiaomi Home (for European models). Alternative applications (eg. Home Assistant) require preliminary configuration of the vacuum cleaner via the original software. Exception: models with support OpenAPI, but they require technical skills for manual configuration.

Why doesn't the vacuum cleaner see the guest network?

Possible reasons:

1. The guest network is assigned a hidden SSID (enable visibility in the router settings).
2. The guest network is assigned a range 5 GHz, and the vacuum cleaner only works on 2.4 GHz.
3. Client isolation is enabled in the router (AP Isolation), blocking device detection.

Solution: Temporarily disable the main Wi-Fi network, leaving only the guest network, and repeat the search on the vacuum cleaner.

How to reset Wi-Fi settings on a Xiaomi vacuum cleaner?

There are two ways:

1. Via the app: V Mi Home Select a vacuum cleaner → Settings → Reset Wi-Fi.
2. Hardware: press and hold the buttons Nutrition + Home (or Nutrition + Spot Cleaning) for 5-10 seconds until you hear a beep. The Wi-Fi indicator will start flashing orange.

After resetting, the vacuum cleaner will forget all saved networks, and you will need to repeat the connection procedure.

Is it possible to connect a vacuum cleaner to public Wi-Fi (in a cafe, hotel)?

Technically yes, but there are limitations:

• The vacuum cleaner can't get through authorization through the portal (like in hotels or airports).
• Public networks are often blocked multicast (multicast) required for the vacuum cleaner to operate.
• In some cases it will help port forwarding on the router, but this requires administrator rights.

The best option is to create access point on your smartphone and connect the vacuum cleaner to it.

What to do if the router does not support WPS?

Alternatives:

• Use guest network (if there is one).
• Connect the vacuum cleaner via QR code (if the router supports generation).
