Check the exact model and use the app instructions intended for that robot. Wi-Fi iRobot lists 2.4 GHz only for i1–i5, and both 2.4 and 5 GHz for i6–i8, j7/j9 and s9. Security The cited setup guidance does not establish WPA3 support for each model. Check iRobot’s requirements for the exact robot. Setup network Some models activate an internal setup network. Its name varies; follow the app prompts. App iRobot HOME or Roomba Home app, depending on model Models Roomba i3, Roomba i7, Roomba j7, Roomba s9, Roomba Combo 10 Max **Checked 2 November 2026.** iRobot’s connected-robot setup and error guidance checked 2 November 2026. Newer robots can use a different Roomba Home app. ## Wi-Fi it needs iRobot’s setup chart lists the bands supported by each robot. Not every Roomba model supports Wi-Fi. - **2.4 GHz only:** iRobot lists the i1–i5, Combo i5, Combo i8 and Wi-Fi-connected 800 and 900 series in this group. - **2.4 and 5 GHz:** the chart lists i6, i7, i8, j7, j9, s9 and Combo 10 Max as dual band. - **Earlier models:** the same chart says models below the 670 do not have Wi-Fi. Check the exact robot before using app setup. - **Combined network names:** confirm that the router provides 2.4 GHz for a robot that needs it. A shared name alone does not reveal the band. - **Security:** check the manufacturer’s model-specific requirements before changing a router setting. Do not assume WPA3 compatibility from Wi-Fi band support. **Kilobat can help.** `kilobat scan` lists the networks around your Mac with their band and channel, so you can see whether yours is on 2.4 GHz at all, and `kilobat channels` names the least crowded channel.

It directs newer product families to separate Roomba Home instructions. 1. Put the robot on its powered charging base. 2. Install the app specified for your model and sign in. 3. Enable Bluetooth if the app requests it. 4. Connect the phone to the intended home network. 5. Select the robot in the app and follow its model-specific prompts. 6. Enter the Wi-Fi password when requested. 7. Wait for the app to confirm setup. If the robot supports only 2.4 GHz, iRobot asks for the phone to use that band during setup. Some models activate an internal network when prompted. ### Change networks later 1. Open the robot in its app. 2. Open **Product Settings › Reconnect or Change Wi-Fi** when available. 3. Follow the prompts for the new network. Labels and steps vary with the app and robot. Check iRobot’s current instructions for your model. **Kilobat can help.** Once it has joined, Kilobat’s **Tools › Devices** lists it with its address and maker, and [new-device alerts](https://kilobat.app/docs/home-network#new-devices) tell you whenever something new joins your home Wi-Fi. ## How much data it uses An online robot exchanges data with its app and service, but the amount depends on the model and features used. A Mac’s bandwidth monitor reports traffic on that Mac. Router counters, if available, can measure the robot’s own connection. The cited iRobot setup and troubleshooting pages do not publish a daily or monthly traffic figure. Do not use a streaming-camera estimate for a vacuum. **Kilobat can help.** Kilobat counts what your Mac sends and receives, app by app, not what other devices use. On a shared or capped connection, its [bandwidth monitor](https://kilobat.app/mac-bandwidth-monitor) and [hotspot data saving](https://kilobat.app/save-hotspot-data) look after the Mac’s share. ## Guest, hotel and dorm Wi-Fi iRobot says connected Roomba setup is designed for home Wi-Fi networks that support device discovery. A guest network can restrict communication between devices. Ask its administrator whether local discovery is allowed. The cited setup page does not promise that a robot can complete a hotel or campus sign-in page. Check with iRobot and the network operator first. If a shared network changes its password or expires access, the robot may need to be reconnected in the app. **Kilobat can help.** `kilobat devices --bonjour` lists the devices your Mac can reach and the services they advertise. If other devices do not appear, client isolation is one possible cause; sleeping devices and discovery settings can also affect results. ## When it won’t connect Check the robot has power and that the phone and home network are available before resetting anything. 1. Check the base is powered and the robot has charge. 2. Confirm the home network works on another device. 3. Check the robot model’s supported Wi-Fi band in iRobot’s chart. 4. Enable Bluetooth if the app asks for it. 5. Choose the correct home network and re-enter its password. 6. Follow the app’s model-specific button prompts. 7. If setup fails, note the app’s error and follow iRobot’s error guide. Some newer Roomba families use a separate setup guide. iRobot lists those models at the top of its HOME app article. **Kilobat can help.** Before you blame the device, Kilobat’s [Why can’t it connect?](https://kilobat.app/guides/recipes/why-cant-it-connect) and `kilobat diagnose` check the Wi-Fi, router, internet and DNS from your Mac. ## When it keeps going offline iRobot lists different checks for different connectivity errors. Start with the code shown in the app. 1. Check the robot is charged and properly seated on its base. 2. Check whether another device can use the same network. 3. Open the robot’s Wi-Fi settings in the app and check its network. 4. Reboot the robot using iRobot’s instructions for your model. 5. Allow about five minutes for it to reconnect. 6. If needed, use **Reconnect or Change Wi-Fi** in product settings. 7. Contact iRobot support if the error continues. A reboot and a factory reset are different. Consult the model instructions before a reset that can remove configuration. **Kilobat can help.** `kilobat health-history` shows whether the router or the internet dropped at the same time, and `kilobat devices --all` marks a device that stopped answering as away. To check the signal where it sits, take your Mac there and use Kilobat’s [radar](https://kilobat.app/guides/recipes/find-better-wifi-spot). ## Questions **Does every Roomba support 5 GHz?** No. iRobot lists i1–i5 as 2.4 GHz only, while i6–i8, j7/j9 and s9 support both bands. **What is the Roomba setup network?** Some robots activate an internal Wi-Fi network during setup. Follow the app’s instructions for the model. **How much data does a Roomba use each month?** The setup and error pages cited here do not publish a monthly total. ## Sources - [iRobot: Set up a Wi-Fi connected robot with iRobot HOME](https://homesupport.irobot.com/articles/en_US/Knowledge/17734) - [iRobot: Connectivity error codes](https://homesupport.irobot.com/articles/en_US/Knowledge/15431) - [iRobot: Change the Wi-Fi network](https://homesupport.irobot.com/articles/en_US/Knowledge/9005) - [iRobot: Setup guide for i and j series robots](https://homesupport.irobot.com/articles/en_US/Knowledge/32672) Checked on 2 November 2026. ## See your network from your Mac Kilobat is a Mac menu-bar app with a CLI and an MCP server for AI agents. It lists the devices on your Wi-Fi and says when a new one joins, keeps a history of the router’s and the internet’s health, scans nearby channels, and shows which app on your Mac is using the network.
