How to reconnect Roborock after changing routers
If you upgraded your home network, replaced your ISP modem, or moved to a mesh system, your Roborock may stop appearing in the app.
This guide explains how to reconnect Roborock after changing routers and covers the Wi-Fi settings, app steps, and troubleshooting checks that usually fix the issue fast.
Why your Roborock disconnects after a router change
Roborock vacuums connect to your home Wi-Fi using the network name, password, and radio settings that were active when you first paired the device.
When you switch routers, one or more of those details often change, so the robot can no longer authenticate to the network.
Common causes include a new SSID, a different Wi-Fi password, 5 GHz-only settings, band steering, hidden SSIDs, or router security modes that are incompatible with older smart-home devices.
In many cases, the vacuum itself is fine; it simply needs to be added to the new network again.
Before you start: what you need
Have these items ready before re-pairing your Roborock:
- Your new Wi-Fi network name and password
- A smartphone with the Roborock app installed
- Bluetooth and location permissions enabled on the phone
- The vacuum, docked and powered on
- Access to the router admin page if troubleshooting is needed
If your robot supports both 2.4 GHz and 5 GHz, remember that many Roborock models still pair more reliably on 2.4 GHz during setup.
How to reconnect Roborock after changing routers
The exact menu names vary slightly by app version, but the process is similar across Roborock and Mi Home environments.
- Open the Roborock app and sign in to the same account you used before.
- Make sure your phone is connected to the new home Wi-Fi.
- Check that Bluetooth and location access are turned on for the app.
- Tap the option to add a new device or reconnect a robot.
- On the Roborock, press and hold the Wi-Fi reset buttons until the indicator starts blinking as instructed by your model.
- Follow the on-screen setup steps and enter the new Wi-Fi password.
- Wait for the vacuum to confirm the connection, then name the device if prompted.
Once the pairing succeeds, the robot should appear online in the app and resume map access, schedules, and cleaning history if the model supports cloud sync.
What if your old map disappears?
Changing routers usually does not erase the map stored on the robot, but the app may temporarily show it as unavailable if the device is offline for too long.
After the robot reconnects, the map may reappear automatically.
If the map is still missing, check whether the vacuum was added as a new device instead of reconnected to the existing one.
In some cases, logging back into the original Roborock account restores access to saved rooms, no-go zones, and custom routines.
Router settings that can block Roborock
If pairing fails repeatedly, the router configuration is often the real issue.
Roborock devices can be sensitive to certain Wi-Fi settings, especially on newer routers and mesh systems.
1. Use a 2.4 GHz network for setup
Most Roborock vacuums pair best on 2.4 GHz.
If your router combines 2.4 GHz and 5 GHz under one SSID, temporarily separating them can make setup easier.
2. Check WPA2 or mixed security
Many smart-home devices work best with WPA2-PSK or WPA2/WPA3 mixed mode.
Pure WPA3 mode can cause connection failures on some robot vacuum models.
3. Disable hidden SSID during pairing
If your network is hidden, make it visible during setup.
Hidden SSIDs often create discovery problems because the app must detect the network quickly and reliably.
4. Avoid special characters in the Wi-Fi name or password
Roborock usually handles normal Wi-Fi credentials well, but certain symbols or overly long passwords can cause setup errors.
If nothing else works, test with a simpler network name and password.
5. Keep the robot close to the router
Weak signal strength can interrupt the pairing process.
Place the robot within a few feet of the router during setup, then move it back to the dock afterward.
Troubleshooting when Roborock will not reconnect
If you still cannot get the vacuum back online, work through these checks one by one.
- Restart the robot by powering it off and back on.
- Restart the router and wait until Wi-Fi is fully stable.
- Confirm your phone is on the same 2.4 GHz network used for pairing.
- Turn off mobile data temporarily so the app does not switch networks mid-setup.
- Remove any VPN or private DNS settings on the phone.
- Reset the Roborock Wi-Fi settings and try the pairing process again.
Mesh networks can also cause problems if the robot tries to connect to a weak node or if band steering forces it onto the wrong band.
If your router app offers a pause or split-band option, test that during initial setup.
How to reconnect without deleting everything
In many homes, you do not need to factory reset the Roborock just because the router changed.
A Wi-Fi reset is usually enough because it preserves maps and cleaning preferences on the device or in the cloud account.
Use a full factory reset only if the robot refuses to pair after multiple attempts, or if the app specifically instructs you to reinitialize the device.
Before doing that, confirm that your maps are backed up in the app and that you are logged into the correct account.
Best practices for future router changes
To reduce downtime the next time you upgrade networking gear, keep your smart-home setup consistent.
- Reuse the same SSID and password if possible.
- Keep a dedicated 2.4 GHz network available for IoT devices.
- Document your current Wi-Fi security mode and router settings.
- Update the Roborock app and firmware before major network changes.
- Test the robot immediately after installing a new router or mesh system.
If you plan to move to a new ISP router, transferring the old Wi-Fi name and password can sometimes let Roborock reconnect automatically without a new pairing session.
When to contact support
If the vacuum still cannot connect after you verify Wi-Fi band, security mode, credentials, and app permissions, the issue may involve firmware or hardware.
At that point, contact Roborock support with your model number, app version, router model, and a short description of the error message.
Support can often tell you whether your specific model has a known compatibility issue with certain mesh systems, routers, or WPA3 configurations.
