Connecting the robot vacuum cleaner Xiaomi 1S to the network and the application: a complete guide with pictures and tips

The Xiaomi Mi Robot Vacuum 1S is a smart device that makes cleaning a home much easier, but its first connection can raise questions even among experienced users. Unlike newer models (such as the Xiaomi Robot Vacuum-Mop 2 Lite+), the 1S requires a special approach to configuring Wi-Fi due to the limitations of the security protocol and the specifics of working with the Mi Home application. In this article, we will discuss not only the basic steps, but also hidden nuances that the manufacturer often does not mention in the official instructions.

The main problem with connecting Xiaomi 1S is incompatibility with 5GHz Wi-Fi networks and some protected-control (WPA3) routers. If you encounter a “failed to connect” error or the robot constantly resets the connection, the solution lies in the router settings, not the vacuum cleaner itself. We will detail how to fix this, and we will show you how to add the device to Mi Home correctly to avoid problems with geofences and cleaning schedules in the future.

This article will be useful for both beginners and those who have tried to connect the vacuum cleaner, but have encountered errors, and we will also discuss compatibility with alternative applications (for example, Home Assistant), update the firmware to the latest version and give recommendations on optimal settings for different types of rooms. If you plan to use the Xiaomi 1S with voice assistants (Alice, Google Assistant), here you will find the current instructions.

1.Preparation for connection: what to do before turning on the vacuum cleaner

Before you start setting up, make sure you follow all the steps, and failure to comply with these conditions is the main cause of 80% of connection errors.

• 📱 Install the Mi Home app. Download it from Google Play or the App Store. Version should be at least 6.0.100 (check in the app settings).
• 🌐 Set up a Wi-Fi router. Xiaomi 1S robot only works with 2.4GHz networks and the WPA2-PSK security protocol. If you have a dual-band router, split the networks (e.g., create a separate network MyWiFi_2G).

Pay special attention to router settings. If you have features like Band Steering (automatic switching between 2.4 and 5 GHz), MAC- filtering or Googles DNS enabled, you need to turn them off while you connect. Also check that the DHCP router settings do not limit the number of connected devices — some providers default to limit 10-15 gadgets.

⚠️ Warning: If you use a mesh system (e.g., Xiaomi Mi Mesh or TP-Link Deco), temporarily connect the vacuum cleaner to the main router.

2. Step-by-step instructions: how to connect Xiaomi 1S to Wi-Fi via Mi Home

Now, to the process of connecting, follow the instructions strictly by step, and skipping any point can lead to an error.

1. Turn on the vacuum cleaner. Press and hold the power button on the robot body for 3 seconds until you hear the beep. The indicator should light up in blue (if flashing red, the device is discharged).
2. Launch the Mi Home app. Sign up with your Xiaomi account (if you don't have one, sign up) and select Russia (or Mainland China if you plan to use Chinese firmware).

If you have a “Cannot Connect to the Network” error during the Wi-Fi connection stage, try the following:

• 🔄 Restart router and vacuum cleaner (hold power button for 10 seconds).
• 📵 Disable VPN or proxy on your smartphone — they can block the connection to Xiaomi servers.
• 📡 Change the Wi-Fi channel in the router settings to 1, 6 or 11 (they are less loaded).

Make sure Wi-Fi is running at 2.4GHz

Turn off WPA3 and turn on WPA2-PSK

Charge the vacuum cleaner to at least 30%

Place the docking station in the zone of the confident signal

Remove old devices from Mi Home (if any)

First launch setup: calibration, room map and base parameters

Once the Wi-Fi connection is successful, the robot must be set up in an initial setting, which determines how effectively the vacuum cleaner will handle cleaning.

First, calibrate the sensors:

1. Place the vacuum cleaner on a flat surface (for example, on the floor in the center of the room).
2. In the Mi Home app, go to the robot settings → General settings → Sensor calibration.
3. Follow the voice cues. The robot will make a few rotational movements -- don't interrupt the process.

Then create a map of the room:

1. Click the Cleaning button in the app and select Full Cleaning mode.
2. Wait for the robot to go around all the rooms, and this process can take 20-40 minutes depending on the area.
3. Once you finish cleaning, an interactive map will appear in the app, and break it into zones (e.g., Kitchen, Bedroom) using the Map Edit tool.

⚠️ Warning: If the robot doesn't return to the dock after the first run, check: Station to wall distance must be at least 50 cm on each side. Station area lighting - sensors may not work in the dark. Obstacles (wires, high-pile carpets)

💡

If the robot is constantly "lost" in a large room, divide it into several zones manually, to do this in editing the map draw lines between the rooms.

4. Solving common problems when connecting Xiaomi 1S

Even with the correct following of the instructions, errors can occur, and let's look at the most common ones and how to fix them.

Error: "Unable to connect to the network"

Causes and solutions:

• 📶 Incorrect Wi-Fi password – check the letter register and no extra characters.
• 🔒 Unsupported security type – switch the router to WPA2-PSK (AES).
• 📵 Weak signal – move the router closer or use a repeater.
• 🌍 The wrong region in Mi Home – choose Russia or Mainland China.

Error: "Offline device"

If the robot is connected, but after a while it is disconnected:

• ⚡ Check the power supply — it is possible that the vacuum cleaner is discharged or the docking station is not connected to the network.
• 🔄 Reboot the router — sometimes the DHCP- server forgets the device.
• 📱 Update the firmware through Settings → Software Update.

Error: "Cannot add the device"

If Mi Home doesn't see the vacuum cleaner:

• 🔄 Reset the robot settings – hold the Power and Home buttons for 10 seconds until the beep.
• 📱 Remove the app cache in your smartphone settings.
• 🌐 Try another region in Mi Home (e.g. Singapore or Hong Kong).

5. Alternative ways to manage: Home Assistant, Alice and Google Assistant

If you use a smart home based on Home Assistant or voice assistants, the Xiaomi 1S can be integrated there, too.

Instructions for Home Assistant:

1. Install the Xiaomi Miio component via HACS or manually.
2. Get the device token using the miio-cli script or through the Mi Home Token Extractor app (root required on Android).
3. Add configuration.yaml: vacuum: - platform: xiaomi_miio host: IP_ADRESS ROBOT TOKEN: YOUR TOKEN

To connect to Alice (Yandex) or Google Assistant:

1. In the Mi Home app, go to the robot settings → Voice Assistant.
2. Select the right assistant and follow the instructions on the screen.
3. For Alice, you will need to link your Xiaomi account to Yandex through Settings → Devices → Smart Home.

⚠️ Warning: When using Home Assistant, disable cloud sync in Mi Home to avoid command conflicts. Also note that voice commands via Alice only work when an active Internet connection is in place.

6. Updating firmware and optimizing work

Regular firmware updates improve stability and add new features to check the relevance of the version:

1. Open Mi Home → Select your vacuum cleaner → Settings (⚙️) → Software Update.
2. If a new version is available, click Update and wait until it is completed (the robot will restart).

To optimize the work, we recommend:

• 🗺️ Regularly update the map (once a month) – to do this, run the robot in the mode of Cleaning the borders.
• 🔋 Clean sensors (especially lidar) with a soft napkin every 2 weeks.
• ⏰ Set your schedule for when you’re not home, and it will reduce the network load.

💡

Updating the firmware through Mi Home is the safest way, but if the robot is stuck during the process, don't turn it off for 20 minutes. 90% of the time, it will complete the installation on its own.

7. Reset to factory settings: when and how to do

If the robot is unstable or you plan to sell it, you may need a complete reset, which will remove all settings, room maps and Wi-Fi data.

Instructions:

1. Hold the power and home buttons at the same time for 10 seconds until you hear a beep.
2. The indicator will start flashing yellow, which means that the reset is started.
3. After the reboot, the robot will return to factory settings (the indicator will turn blue).

If the discharge did not work:

• Check that the vacuum cleaner is charged (battery level is not lower than 20%).
• Repeat the procedure by holding the buttons for 15 seconds.
• If the indicator flashes red, contact Xiaomi for support – a hardware malfunction is possible.

⚠️ Warning: Once reset, the robot will automatically delete from your Mi Home account. To connect it again, you will need to repeat the add-on procedure from scratch.
