Only the iRobot® Roomba® 900 Series Robot Vacuums, which can capture mapping and navigation information via VSLAM, can produce Wi-Fi® Coverage Maps.
What is Wi-Fi® Coverage Mapping Feature?
Wi-Fi Coverage Mapping is a feature that can detect wireless signal strength throughout a user's home to highlight areas that may have poor connectivity. Based on this information, users can take steps to improve wireless signals in their homes where coverage might be poor, potentially resulting in improved customer experience when using connected devices within the home.
As with other Wi-Fi connected devices, Roomba 900 Series Robot Vacuums detect wireless signal strength during normal operation.
With the Wi-Fi Coverage Map feature, Roomba 900 Series Robot Vacuums can highlight areas that may have poor connectivity on the Wi-Fi® Coverage Map.
How a Wi-Fi® Coverage Map is created and viewed?
- Users simply start a Roomba® cleaning job and the robot will methodically collect Wi-Fi signal information as it cleans
- Upon completion of the cleaning job, the app will present a Wi-Fi Coverage Map for the area cleaned that corresponds to the familiar Clean Map
- Users will receive a notification the first time a Wi-Fi Coverage Map is generated
To view the Wi-Fi Coverage Map ➔ navigate to the Clean Map™ Report screen and toggle to the Wi-Fi Coverage Map. 
How Roomba® 900 Series detects Wi-Fi network?
Your Roomba® will only detect the wireless signal strength of the Wi-Fi network with the SSID (a.k.a
Network ID/ Service Set Identifier ID) it is connected to. So, if you have more than one wireless SSID in your home, your Roomba® will not map the signal strength of the wireless networks it is not connected to. If you have multiple Wi-Fi repeaters or access points in your home all sharing a single SSID, your Roomba® will likely show the aggregate signal strength from these devices. However, this may vary depending on how your Wi-Fi® devices are configured, where they are located, and the layout of your home.
The service displays Wi-Fi signal strength. In many cases, the location(s) of the access points can be inferred from the signal strength on the map, but iRobot® is not displaying an icon with the access point location(s).
The Wi-Fi Coverage Map will reflect only the signal strength for the single network for which your robot is configured. Your Roomba® does not roam between independent networks. It is provisioned to a specific Wi-Fi network by you as part of its setup process.
Note: The service alert when your outside wireless signals detects signal strength only and does not interfere or compete with your signal.
