How to Reset the Xiaomi 1S Vacuum Card: 3 Working Ways (2026)

Xiaomi Mi Robot Vacuum 1S is one of the most popular cleaning assistants, but even it sometimes starts to “glut”: loses a stored map of the room, wrongly builds a route or refuses to navigate the space. Most often, the problem is solved by resetting the cleaning map, but not all owners know how to do it correctly.

In this article, you will find three proven ways to reset the map (via the app, physical buttons, and full reset), and also analyze the typical errors that occur when working with the navigation of the vacuum cleaner. We will not tell the obvious things like “don’t turn off the vacuum cleaner during the process” – instead, focus on specific steps and nuances that the manufacturer does not mention in the official instructions, for example, why after resetting the card, the vacuum cleaner can begin to “forget” the cleaning area and how to avoid this.

Why Xiaomi 1S is losing or building a map wrong?

Before you reset the card, you need to understand the cause of the failure, and in 80% of cases, the problem is not the vacuum cleaner itself, but external factors:

• 🔄 Frequent movement of furniture – vacuum cleaner orients itself by static objects (walls, large appliances). If you move the sofa or cabinet, it can become "confused».
• 📶 Weak Wi-Fi Signal – Xiaomi 1S synchronizes the map with the cloud over the Internet, and if you break the connection, the data can be damaged.
• 🔋 Discharged battery during card saving – if the vacuum cleaner is turned off during route construction, the map will be saved with errors.
• 🛠️ Update firmware – after the software update, user settings are sometimes reset, including cleaning zones.

If the vacuum cleaner has started to wander around the room, ignore virtual walls, or even stop saving the map, try rebooting it first (hold the power button for 10 seconds).

Method 1: Reset the card through the Mi Home app

The easiest and safest method is to use the official Mi Home app (or Xiaomi Home for newer versions), which does not affect other vacuum cleaner settings, so after a reset, you do not have to adjust the schedule or voice assistant again.

Step-by-step:

1. Open the Mi Home app and select your Xiaomi 1S vacuum cleaner on the home screen.
2. Go to Settings → Map (or Clean → Map in new versions of the application).
3. Slap the icon «⋮»** (three points) in the upper right corner of the map.
4. In the drop-down menu, select Reset the card (or Clear the card).
5. Confirm the action - the vacuum cleaner will emit an audible signal and begin the reset process.

And then the robot automatically reboots, and the next time it's turned on, it starts building the map again, and notice that if you have cleanup zones or no-go zones set up, you have to configuring them again, and they're tied to the old map.

Make sure the vacuum cleaner is connected to Wi-Fi|Close all background apps on your phone|Check the battery charge of the vacuum cleaner (minimum 30%)|Shut down. VPN (It can block synchronization with the cloud)-->

⚠️ Note: If the card is not rebuilt after resetting, check Settings → General. → Navigation mode. Sometimes resets to Basic instead of Laser (LDS).

Method 2: Hardware reset through buttons on the body

If the Mi Home app doesn’t work (e.g., the vacuum cleaner is untied or there’s no internet access), you can physically reset the card using buttons on the case, a slightly more complicated method, but doesn’t require a phone connection.

Instructions:

1. Turn off the vacuum cleaner with a long press on the power button (3-5 seconds).
2. Hold the power button and the home button for 10-15 seconds.

This method doesn’t erase other settings (like cleaning schedules or voice commands), but if you’ve held the buttons for longer than 20 seconds, the vacuum cleaner can perform a full factory reset – be careful!

⚠️ Warning: If after a hardware reset, the vacuum cleaner began to “stutter” or make non-standard sounds, check the Settings → System sounds – sometimes reset user tunes.

Method 3: Complete reset to factory settings

If the first two methods didn't work, or if the vacuum cleaner is unstable (e.g., constantly losing contact with the application), the last resort is a complete factory reset, which erases all data, including:

• 🗺️ Preserved maps of premises
• ⏰ Cleaning schedule
• 🔊 Voice commands and assistant settings
• 📶 Wi-Fi connection data

How to perform a complete reset:

1. Turn on the vacuum cleaner and wait until it loads (the indicator should burn blue).
2. Hold the Home button for 20 to 25 seconds until you hear three beeps and the orange light flashes.

After a complete reset, the Xiaomi 1S will be like new – you’ll have to reconnect it to the Mi Home, set up Wi-Fi, and update the firmware (if a new version is available).

Common Mistakes After Resetting Your Card and How to Avoid Them

Even after a successful card reset, Xiaomi 1S owners are facing new challenges, and here are the most common ways to solve them:

If the vacuum cleaner starts to get stuck or “lost” in spacious rooms more often after reset, check Settings → Additional → Sensitivity of sensors. Sometimes the reset resets this parameter to a minimum value.

💡

Before the first mapping after reset, make sure there are no moving objects (people, animals) in the room – this will help the vacuum cleaner build a more accurate map.

How to speed up the construction of a new map?

Once reset, Xiaomi 1S will build the map again, and the process can take anywhere from 10 minutes to an hour, depending on the area of the room.

• 🚀 Start with the largest room – the vacuum cleaner remembers the route and then quickly navigates in the rest of the rooms.
• 🔦 Use bright but not blinding lighting – laser sensor works better in diffuse light.
• 🚪 Close the doors to other rooms – so the vacuum cleaner will not “spray” into unnecessary areas.
• 📱 Follow the process in the app – if the map is being built curved, interrupt cleaning and start over.

If you need to restore the vacuum cleaner as quickly as possible, use the manual mapping mode:

1. In the Mi Home app, select Cleanup → Map → Manual Control.
2. Direct the vacuum cleaner around the perimeter of the room, holding your finger on the screen.
3. After you walk around all the walls, click Save the map.

This method takes 3-5 minutes and is suitable for small apartments, but remember: a hand map is less accurate than an automatic one, so for accurate navigation, it is better to let the vacuum cleaner walk by itself.
