We look at all the possible causes of Roborock offline errors and how to fix them.
To fix the Roborock device offline error, you will have to reset your Wifi on the device. To do this, press the Wifi button on your Roborock robot until you hear a notification sound.
You will then have to set up Wifi from scratch on your phone. If this still does not work, change Wifi from 5GHz to 2.4GHz. As long as your Roborock device is offline, you can’t do any tasks.
You must find an appropriate solution to continue enjoying your robot services.
Reasons Why Roborock Won’t Connect to Wifi
If your Roborock device is consistently going offline, there must be a big problem underneath.
While different issues could cause this problem, there are common ones.
Below are the main causes of the device offline Roborock error.
- Poor Wifi Signal due to the location of the robot in relation to the Wifi router
- Using an Inappropriate mobile phone Application to connect Wifi to your device
- You have disabled Location Services on your phone or you have chosen the incorrect location for your robot
- You are using the inappropriate router settings
How to Fix Roborock Device Offline Problems
The above issues can all be resolved by changing how you set up your robot.
You will have to change your Wifi and location settings and place the robot in the right place to get a signal.
Below are the main solutions to the problem.
Solution #1 Move Robot Closer to Wifi Router
The first step you want to take is to adjust your Robot’s positioning.
The Roborock device can only detect your signal when it is a few meters from the router.
If you have set up the robot in a room that is some distance from the router, you won’t be successful.
Solutions to router location problem
- Move the Docking station for the Roborock robot close to your router
- If you are working in areas that are some distance from your router, get a Wifi Extender
- Avoid working with the robot in dead zones
Solution #2 Download the Appropriate Application for Roborock Device
Most people assume that all Roborock devices run on the same application. This is not true.
The application you need to set up your robot depends on the type of Roborock robot you are using.
There are two applications that can be used to run Roborock robots. You can either use the Roboroc App or the Mi Home app.
The application you use depends primarily on your type of robot.
How to resolve application problem
- If you are using the Roborock app but Wifi won’t connect, try changing to the Mi Home app
- Check the Roborock robot series to know which application it should use
- For Roborock S4, S5 Max, S6, S6 Pure and S6 MaxV only use the Roborock application from app store
- For Roborock Xiaowa E2/3, E4, and S5 you should only use the Mi Home app
Note: Both apps have similar interfaces and features but are tailored to work for specific devices.
If you use an application on the wrong device, it may work for a while but you will run into issues.
Solution #3 Enable Location Permission and Choose Location
The location of your robot determines how it functions. All Roborock devices are designed to work based on locality.
In other words, make sure you set your accurate location on the Roborock application when setting up the robot.
Besides selecting the right location, make sure you also issue location permission for your app on the phone.
This way, the app will be able to detect your robot.
How to allow location permission on Android
- Swipe down the quick-access menu from the top of your screen
- Tap and hold on Location
- Tap on App Location Permissions
- Find the Roborock app you are using
- Change its permission to “Allowed All The Time”
Give location permission on iPhone
- Go to Settings
- Tap on Privacy
- Select Location Services
- Toggle the button to Turn it On
Note: This action will turn on location permission for all applications.
If there is a specific app that you do not want to have permission access to, find it and turn the location off.
Solution #4 Connect Your Robot to 2.4GHz Wifi
The most common cause of the problem with the robot not detecting Wifi is based on the type of Wifi you are using. The Roborock robot can only use 2.4GHz Wifi.
This is actually the case with all other robots in the market. This is because the 2.4GHz Wifi extends to a wider range.
The problem is that most modern routers offer both 2.4GHz and 5GHz. If your Wifi offers 5GHz alone, it may not work with the Roborock router.
How to connect to the appropriate Wifi frequency
- Check on the sticker behind your router to determine if it offers 2.4GHz or not
- If the router offers 2.4GHz only, you do not have to do anything
- If the router offers both 2.4GHz and 5GHz frequencies, you will have to assign each frequency a unique SSID
- Login to your router portal using the details at the back of your router
- Tap on Wireless Menu options
- Tap on SSID and allocate different names to the 2.4GHz and 5GHz bands
- When you connect your robot and phone, make sure they are both connected to the 2.4GHz band
Note: Do not use special characters in your password since the Roborock robot may fail to recognize them.
Solution #5 Reset Your Roborock Device Wifi Connection
After making all the above changes, you may now want to reset your Roborock robot connection. This step should help set up your robot to the Wifi in the most appropriate manner.
What you have to do here is completely disconnect it from Wifi and start the setup fresh.
Steps to reset Roborock device Wifi connection
- Open your top panel on the Roborock robot to access the Wifi indicator light
- Press the Power and Home buttons simultaneously for a few seconds or until you hear a voice prompt
- The Wifi indicator light will slowly Flash, an indication that the Wifi connection has been reset
- On your phone go to Wifi and select the home Wifi you want to set your Roborock
- Go to your Roborock application of choice and tap on the +Button in the upper right corner
- Select your Generically Named Roborock device and tap on reload
- You will reload everything including maps to complete setting up your device to Wifi
Solution #6 Factory Reset Your Device
If all the above options do not change the situation, your only hope will be to factory reset your device.
This is where you set back the device to factory mode.
This will erase all your settings and programming. However, it is the most ideal solution to your Roborock device offline error.
Steps to reset the Roborock robot
- Press and Hold the Home button for about 3 to 5 seconds
- Using a pin, press the Reset Button which is just next to Wifi LED once
- The Power button, Spot Cleaning button, and Home button lights will go off
- Do not release the Home button even after the lights go off keep holding it for about 5 more seconds
- When you hear a ton stating “Restoring the initial version” let go of the home button and wait for the system to reboot
There are many solutions to the Roborock device offline error. The solution you take will depend on the nature of your problem.
If your device has never connected to Wifi, you should probably consider location. If your device has been working and suddenly stopped, you should consider resetting the connection.
