How to connect Xiaomi Mi Robot Vacuum 1S to Wi-Fi and app: full instruction 2026

Introduction: why you need the right setup of a robot vacuum cleaner

Xiaomi Mi Robot Vacuum 1S is not just a cleaning device, but a full-fledged assistant in a smart home. However, many users face problems already at the first connection stage: the device does not find the network, the application gives errors, and the manufacturer’s instructions are often too concise. In this article, we will analyze all the stages of settings from unpacking to the first cleaning, and also explain how to avoid typical errors and optimize the vacuum cleaner.

The 1S model features LDS laser navigation, which requires proper calibration when it first starts, and integrates into the Mi Home ecosystem, allowing it to be controlled via voice assistants (like Alice or Google Assistant), but it requires first connecting the vacuum cleaner to Wi-Fi correctly and synchronizing it with the application.

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

Before you turn on the Xiaomi Mi Robot Vacuum 1S, make sure all the preconditions are met.This will save you most of the problems during the setup phase.

• 📱 Install the Mi Home app. Download it from Google Play or the App Store. Version must be at least 6.5.400 (check in the app settings).

Also check the configuration: the box should have a docking station, power supply, spare HEPA-filter, side brush and instructions. If something is missing, go to the store - it can be a marriage or incomplete delivery.

⚠️ Warning: Do not connect the vacuum cleaner to Wi-Fi via public networks (such as a cafe or hotel) The device requires a stable connection to the home network with support for the protocol. IEEE 802.11 b/g/n. Otherwise, synchronization with Mi Home will not be possible.

Installation of the Mi Home application and account registration

The Mi Home app is the central control of all Xiaomi devices, and without it, you can't set up a cleaning schedule, update your firmware, or use voice control. Here's how to install and register it correctly:

1. Download and install Mi Home (links above). When you first start, select Russia (or your country), which is important because the region depends on the availability of servers and updates.
2. Click "Register" and enter a valid email or phone number. Use real data, and that address/number will receive a confirmation code.

If you register for a server unavailable error, try changing your region to Singapore or Germany, which can help you bypass the time limit, and check if your phone has a VPN enabled (if so, turn it off).

Xiaomi Mi Robot Vacuum 1S is connected to Wi-Fi

Now, to the most important step, connecting the vacuum cleaner to the network, follow the instructions carefully, as any error can lead to failure.

1. Turn on the vacuum cleaner by pressing and holding the "Power" button on the case for 3 seconds. Wait for the beep and voice message in Chinese (this is normal).
2. In the Mi Home app, select the category "Vaccelerates", then the model "Mi Robot Vacuum 1S". Click "Add".
3. Make sure the vacuum cleaner emits an audible signal (two short horns), if not, restart it by holding the Power button for 10 seconds.
4. The phone will request to connect to the "MiRobot-XXXX" network (where XXXX is your device's unique identifier).
5. Return to the Mi Home app and select your home Wi-Fi network (2.4GHz). Enter your password and wait until the connection is completed (usually takes 1-2 minutes).

If you have an error in connection to MiRobot-XXXX, try:

• 🔄 Reboot router.
• 📵 Disable mobile data on your phone (sometimes it interferes with the connection).
• 🛠️ Reset vacuum cleaner settings (hold "Power" and "Spot Clean" at the same time for 10 seconds).

Make sure the router supports 2.4 GHz |

Turn off the VPN on your phone |

Check that the Wi-Fi password is entered without errors |

Remove old devices from Mi Home (if you have any)-->

⚠️ Note: If the vacuum cleaner is connected to the network but appears as “Offline” in the app, check the settings of the router’s firewall. Some models (such as TP-Link or Keenetic) block traffic from Xiaomi devices. MAC-vacuum cleaner address on the exclusion list.

First launch setup and calibration

Once connected to Wi-Fi, the vacuum cleaner will require the initial calibration, a process that is necessary for the LDS laser sensor to work properly and map the space.

1. Place the vacuum cleaner on a flat surface (e.g., in the center of the room) and make sure there is enough space around it (1.5 m in radius).
2. In the Mi Home app, click "Start cleaning." The vacuum cleaner will start to rotate slowly, scanning the room.
3. Wait until the process is complete (usually takes 3-5 minutes) and do not interrupt it or move the device manually.
4. After calibration, the vacuum cleaner will return to the docking station, and the app will show a message "Calibration complete."

If the calibration was completed with an error ("LDS error" or "Card failure"), the reasons may be as follows:

💡

If the vacuum cleaner is constantly "lost" and can't build a map, try sizing it in another room (like a hallway) and then moving it to the main room, sometimes helping to bypass LDS errors.

Optimization of work: settings in the Mi Home application

After successful connection and calibration, you can start fine-tuning the vacuum cleaner. The Mi Home app offers the following options:

• 📅 Cleaning schedules. You can set the days and times of automatic cleaning, like 10:00 a.m. every day when you're not home.
• 🗺️ Zone cleaning: divide the room into zones and indicate which ones should be cleaned more often (e.g. kitchen every day, bedroom once a week).
• 🔊 Suction level. Select mode: Quiet (for night cleaning), Balanced (default) or Maximum (for highly contaminated surfaces).
• 🚫 No-go zones: Draw areas on a map where the vacuum cleaner cannot enter (e.g., near a cage with an animal or fragile objects).

You can also set up:

• 🔄 Enable automatic map update (recommended for frequently changing environments).
• 📶 Set up notifications of completion of cleaning or errors.
• 🔋 Monitoring the battery and wear of brushes.

Important: If you use a vacuum cleaner in a multi-storey house, you need to create a separate map for each level, and move the device to another floor and start cleaning manually, the app will automatically prompt you to save a new map.

Solving common problems after connection

Even after successful setup, users often face typical problems, and here are the most common ones and ways to fix them:

• 🔴 Vacuum cleaner does not connect to Wi-Fi after router restart Reason: Dynamic IP-address or change Wi-Fi channel. Solution: In router settings, fix MAC-vacuum address behind static IP or set the mode "AP Isolation" (if it was turned off).
• 🔄 The device is constantly "hanging" during cleaning Reason: Weak Wi-Fi signal or interference from other devices Solution: Move the router closer to the center of the house or install a Wi-Fi repeater.
• 🗺️ Map of the room is built incorrectly Cause: Dirty sensors LDS Solution: Wipe the sensors with a soft napkin (no alcohol!) and check if the sensor on the top panel of the vacuum cleaner is closed.
• 🔋 Fast battery discharge Cause: Battery wear or maximum power operation Solution: Replace the battery (the original has a capacity of 5200 mAh) or reduce the suction level.

If the vacuum cleaner produces an error of "Error 10" (the problem with the main brush), remove it and clean it of the wound hair or thread.

1. Turn the vacuum cleaner over.
2. Press the latches on the sides of the main brush and remove it.
3. Remove the debris from the axis and set the brush back, making sure it rotates freely.

💡

If the vacuum cleaner has stopped responding to commands from the app, first check the Wi-Fi connection and then restart it (holding the Power for 10 seconds). 90% of the time, this solves the problem.
