“Stop sending a card” in Xiaomi: what is this mistake and how to fix it

You saw a notification on your smartphone from the Mi Home or Mi Robot app saying “stop sending the map” — and now you don’t know what that means? — This error appears in Xiaomi robot vacuum cleaners (Mi Robot, Viomi, Dreame series) and is related to the mapping system. Most of the time, the problem is solved in 5 minutes, but sometimes requires a deeper setup.

In this article, we will discuss:

• 🔍 What does the “stop card sending” message mean and why does it appear?
• 📱 Step-by-step steps to fix the error in the Mi Home app
• ⚙️ Technical causes of failure and how to prevent them in the future
• ❌ What can not be done to avoid aggravating the problem

The error is not critical, as the vacuum cleaner will continue cleaning without saving a map of the room, which means that once it is done, the robot will forget the location of furniture, cleaning areas and virtual walls, and if you ignore the problem, you may have difficulty adjusting the schedule or zoning over time.

What does it mean to “stop sending a card” to Xiaomi?

The message “stop map upload” (or “stop map upload” in the English version) appears when the Xiaomi robot vacuum cleaner tries to transfer the data about the room map to the Mi Home cloud, but encounters an obstacle.This is not a vacuum cleaner error, but a failure in synchronization between the device and Xiaomi servers.

The map of the room is created using a laser rangefinder (LDS) or a camera (in models with visual navigation), and this data is processed by the vacuum cleaner processor, and then sent to the application for display, and if communication is interrupted, the system gives an alert.

• 🌐 Cloud sync – the card is stored on Xiaomi servers so you can control the vacuum cleaner from different devices.
• 📡 Local storage – some models store the card in the vacuum cleaner memory, but without the cloud it can not be edited through the application.
• ⚠️ Sending error – means that the data has not reached the server and the card is not updated.

It's important to understand that this message itself doesn't break the vacuum cleaner. It will continue cleaning, but without saving the changes in the map. For example, if you moved the sofa, the robot may encounter it on the next cleaning because it "does not remember" the new location.

💡

If the vacuum cleaner is working but the map is not updated, try manually resending data through the Settings menu → Map → Update the map in the app.

The main reasons for the error of “stop sending the card”

The problem arises from failures on one of three levels:

1. Network connection – weak Wi-Fi, traffic blocking, or router problems.
2. Xiaomi servers are temporary disruptions in the work of cloud services (especially relevant for users from regions with limited access).
3. Software is an outdated firmware vacuum cleaner or Mi Home application.

The most common reason is an unstable Internet connection: Xiaomi’s robot vacuum cleaner requires a constant connection to 2.4 GHz Wi-Fi at 5 GHz, which is not supported by most models. If the signal is weak or interrupted, the maps do not have time to sync.

⚠️ WARNING: If you use a guest network or Wi-Fi with customer isolation (AP Isolation, the vacuum cleaner will not be able to communicate with Xiaomi servers.

How to Fix an Error: Step-by-step Instruction

Start with the simplest of actions and move on to the more complex ones if the problem is not solved.

Check the connection of the vacuum cleaner to Wi-Fi|Reboot the router|Update the Mi Home app|Restart the vacuum cleaner (on button)|Check the status of Xiaomi servers (downdetector.com)-->

1. Checking the network connection

Make sure the vacuum cleaner is connected to a 2.4 GHz network (not 5 GHz!).

1. Open Mi Home → Select your vacuum cleaner → Settings → Wi-Fi.
2. If the status is "Disconnected", connect again.
3. Check the internet speed on your phone at the same point where the vacuum cleaner works (should be at least 2 Mbps).

2. Resetting network settings on vacuum cleaner

If the Wi-Fi connection is not synced:

1. Press the Wi-Fi button on the vacuum cleaner body (usually next to the power button) for 3-5 seconds until you hear an audible signal.
2. In the Mi Home app, select “Add device” and plug the vacuum cleaner again.

3. Firmware update

Outdated software can cause synchronization conflicts to update:

1. Open Mi Home → select vacuum cleaner → Settings → Update firmware.
2. If an update is available, install it (vacuum cleaner must be connected to charging).

⚠️ Warning: Do not interrupt the upgrade process! If the vacuum cleaner goes off the power during the firmware installation, it can lead to a breech (software breakage).

4. Card reset and re-scan

If the error persists, try to delete the current card and recreate it:

1. At Mi Home, go to the "Map" section.
2. Click Remove the card (or “Reset the card”).
3. Start the vacuum cleaner for cleaning - it will create a new map.

Common myths about the “stop card sending” error

There are many "advice" on the Internet that not only don't help, but can also hurt, and we'll look at some of the most popular misconceptions.

Myth 1: “You need to dump the vacuum cleaner to the factory settings”

This is an extreme measure that erases all settings, including cleaning schedules and areas, and 99% of the time, the error is resolved without being completely reset, and only apply it if other methods have failed.

Myth 2: “The problem in the laser rangefinder (LDS)”

LDS is responsible for building the map, but not sending it to the cloud. If the vacuum cleaner is able to navigate the space properly, the rangefinder is in good shape. The error is related to the network or the software, not the hardware.

Myth 3: “You should change the region in Mi Home to China”

This can lead to account locking if you are not using the Chinese version of the app. Region only affects the availability of certain features (like voice assistant), but not card sync.

How can we prevent the error from recurring?

To avoid problems in the future, follow these guidelines:

• 📶 Enhance Wi-Fi signal in cleaning areas. Use a repeater or Mesh system if the router is far away.
• 🔄 Regularly update the vacuum cleaner firmware and the Mi Home app.
• 🚫 Don't use it. VPN When working with Mi Home, this can block access to Xiaomi servers.
• 🔋 Keep an eye on the battery. If the level is below 20%, the vacuum cleaner may interrupt the synchronization.

If you encounter a frequent error, try turning off cloud sync (if your model supports local card storage).

1. Go to Settings → Map → Storage of the card.
2. Choose “Local” instead of “Cloud”.

The disadvantage of this method is that you will not be able to control the card from other devices.

💡

A stable connection to Wi-Fi at 2.4 GHz is the main condition for smooth mapping, and if the signal is weak, no settings will help.

What can't you do with that mistake?

Some actions may aggravate the problem or cause data loss.

• ❌ Interrupt firmware updates - this can "brick" the vacuum cleaner.
• ❌ Changing your account region without needing to be blocked.
• ❌ Reset router settings without saving configuration – lose all connected devices.
• ❌ Using unofficial firmware - it deprives of warranty and can disrupt the work LDS.

If the vacuum cleaner has stopped responding to commands after your manipulations, do not try to disassemble it yourself. Contact the Xiaomi service center with the model and a description of the actions that will lead to the failure.
