Your iRobot will not connect to Wi-Fi, or it used to work and now shows offline in the app. Most Roomba, Roomba Combo, and Braava connection problems come from the app flow, the wrong Wi-Fi band, router security, phone permissions, or a stale network session. Start with the iRobot Home app, then move through the network fixes before using a reset.
Reconnect the robot in the iRobot app
Start here when your robot was already set up but now says it cannot connect, cannot connect right now, or appears offline after a router name or password change.
- 1.Open the official app store and update the iRobot Home app.
- 2.Open iRobot Home, then go to Product Settings and Wi-Fi Settings.
- 3.Tap Reconnect or Change Product Wi-Fi.
- 4.Enter your Wi-Fi password.
- 5.Keep the phone near the robot until the app finishes reconnecting.
Choose the right setup path for a new robot
Use this when you are adding a new Roomba, Roomba Combo, or Braava to the app. Current setup starts with either the QR code or the app's product menu.
Scan the QR Code on the box or Quick Start Card. iRobot prints setup QR codes for the 600 series, i series, j series, and s series. The code opens setup or sends you to the app download.
In the app, confirm the detected compatible Wi-Fi network. Follow the on-screen instructions, tap My robot is ready, tap Continue after charging-station setup, then tap Get started.
Check which app your robot uses first. Roomba Mini, Roomba 100/1000, Roomba 200/2000, Roomba Plus 400/500/600, and Roomba Max 700/800 set up in the Roomba Home app. Place the robot on the dock and confirm it is charging, turn on Bluetooth, Location Service, and network access, then select add a New Product and follow the app instructions to connect the robot to Wi-Fi.
Other Roomba, Roomba Combo, and Braava robots set up in the Classic iRobot Home app. When the QR code is missing or hard to scan, open the app menu with the 3 lines button in the upper right corner. Choose Add your product, select the robot model if no nearby product is found, then continue through the model-specific setup screens.
Use a supported phone for setup. iRobot no longer supports iPad or tablet devices during setup, and foldable phones are often classed as tablets.
Switch your phone to 2.4 GHz when your model needs it
A lot of iRobot Wi-Fi failures happen because the phone is connected to 5 GHz while the robot needs 2.4 GHz. Roomba Essential, Roomba i1 through i5 and Combo i5, Roomba Combo i8, Roomba Combo, Roomba 900, Wi-Fi Connected Roomba 800, and Roomba 670 or 690 need a 2.4 GHz setup path.
Open your phone's Wi-Fi settings before setup and choose the 2.4 GHz network. When similar network names appear, pick the one with 2G, 2GHz, or the name without an added 5G label.
If your phone keeps jumping back to 5 GHz during setup, forget the 5 GHz network temporarily. After the robot connects, join the 5 GHz network again on your phone.
If this method fails, move the dock closer to the router and make sure the router is broadcasting 2.4 GHz or a mixed 2.4/5 GHz network.
Fix router settings that block pairing
These router settings stop the app from discovering the robot or reaching iRobot's cloud service.
- 1.Open your router admin app and enable a 2.4 GHz or 2.4/5 GHz mixed network.
- 2.Open Wi-Fi security and change WPA3-only to WPA2 or mixed WPA2/WPA3.
- 3.Turn off VPN or Proxy Server on the phone or router while pairing.
- 4.Use the main home network, or disable Wi-Fi Isolation, AP Isolation, IP Isolation, or Network Isolation on guest or IoT Wi-Fi.
- 5.Open Wi-Fi channel settings and use channels 1-11 in North America or 1-13 outside North America.
Move the dock closer and confirm the robot has power
This applies when setup times out, the app loses the robot, or the robot never wakes up during pairing. A dead or fully discharged iRobot will not connect to Wi-Fi.
Place the dock on a level, obstacle-free surface as close to the router as possible, connect it to power, and set the robot on the dock. Confirm that it is charging before you retry setup.
Press the robot's buttons and check that it lights up or runs manually. If setup activation makes no sound, unplug the dock, plug it back in, place the robot on the dock again, and wait for the brief dock light or robot beep.
For charging-related connection errors, align the metal charging contacts on the robot and charging station before starting Wi-Fi setup again.
Restart everything in the right order
This fixes stale app, robot, router, and cloud connection sessions.
Force close the iRobot Home app, then reopen it.
For cloud connection errors, wait 30 seconds after reopening before trying again.
Restart your phone, open iRobot Home, and retry the connection.
Unplug your router for 10 seconds, plug it back in, and wait 2 minutes.
For mesh Wi-Fi, restart the main router first, then unplug and reconnect each secondary node.
Reboot the robot from the app when it is reachable. In the New Roomba Home app, go to Robots, tap the three dots, choose Reboot Roomba, then tap Reboot Roomba again.
In the Classic iRobot Home app, go to Product Settings, choose Reboot Roomba, then tap Reboot Roomba again.
Allow the phone permissions the app needs
The most common phone-side cause is the app missing the permissions it needs during Bluetooth and Wi-Fi setup.
On Android, allow Wi-Fi Connection, Bluetooth Connection, Location, and Media permission when the app asks.
On iPhone, allow Location, turn Bluetooth on when prompted, and enable Precise Location during Bluetooth setup.
If permissions are already correct, uninstall and reinstall iRobot Home from the official app store, then sign in and try setup again. This also puts you on the latest app version.
When one phone still will not complete setup, try another supported phone. If the app works on the second phone, something on the original device is blocking the setup signal.
Clear account and lock problems before pairing
If the app says the robot is already registered to another account, choose Change ownership. Follow the on-screen steps, wait for the robot to boot up, then register it again.
When your account has reached its product limit, remove a robot you no longer use from iRobot Home by going to Product Settings, About my robot, and Remove Device from Account.
If setup fails with Child Lock or Child & Pet Lock errors, turn off Child & Pet Lock in the app or device setting and run setup again.
Older Android setup errors WF030C, WR030C, and WF02D0 were addressed by iRobot app version 7.17.6, released on January 28, 2026. The current fix is to update the app and use a supported phone.
Use a factory reset as the last resort
A factory reset is the final move when reconnecting, router fixes, permissions, and reboots do not bring the robot back online. The app reset removes the robot from the app and account and disassociates saved cloud data.
In the Classic iRobot Home app, go to Product Settings, then About, then Remove Device from Account. In the New Roomba Home app, select the robot, open Robot Settings, then About Roomba, then Factory Reset and Remove Robot.
On robots with Imprint Smart Map, turn on Save maps during factory reset on the reset screen before resetting. Robots without Imprint Smart Map do not show that option.
If this method fails, try setup on a separate supported network or a two-phone hotspot to isolate a router problem, then contact iRobot support if the robot still cannot connect.
Frequently Asked Questions
Why does my iRobot only fail on my home Wi-Fi?
Your router can block setup with WPA3-only security, guest network isolation, unsupported channels, disabled DHCP, or a 5 GHz-only setup path. Use WPA2 or mixed WPA2/WPA3, the main home network, and a 2.4 GHz or mixed network.
Can I connect a Roomba to 5 GHz Wi-Fi?
Some models support 5 GHz, including Roomba Combo 10 Max, Combo j7+/j9+, Combo j5, j7/j9, s9, i6/i7/i8, and Braava jet m6. Roomba Essential, i1-i5, Combo i5, Combo i8, Combo, 900, Wi-Fi Connected 800, and 670/690 need 2.4 GHz during setup.
Does rebooting my Roomba delete maps or schedules?
No. A normal reboot does not delete maps, schedules, or preferences. A factory reset is different and should be saved for last.
Why is my older Roomba 900 series still not connecting?
For cloud errors such as c181, c182, or c510, check the manufacturing date. iRobot says some 900 series robots manufactured between 2015 and 2018 may no longer be supported.
