+
+The `roomba` component allows you to control your [Roomba](http://www.irobot.com/For-the-Home/Vacuuming/Roomba.aspx).
+
+<p class='note'>
+This platform has only been tested with an iRobot Roomba 980, but should work find
+with any Wi-Fi enabled Roomba like the 690, 890 or the 960.
+</p>
+
+To add your roomba vacuum to your installation, add the following to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+vacuum:
+  - platform: roomba
+    name: My Roomba
+    host: IP_ADDRESS_OR_HOSTNAME
+    username: BLID
+    password: PASSWORD
+```
+
+Configuration variables:
+
+- **host** (*Required*): Hostname or IP address of the Roomba.
+- **username** (*Required*): Username (BLID).
+- **password** (*Required*): Password.
+- **certificate** (*Optional*): Path to your certificate store (Default: `/etc/ssl/certs/ca-certificates.crt`)
+- **continuous** (*Optional*): Whether to operate in continuous mode (Default: `True`).
+
+<p class='note'>
+The Roomba's MQTT server only allows a single connection. Enabling continuous
+mode will force the App to connect via the cloud to your Roomba. [More info here](https://github.com/NickWaterton/Roomba980-Python#firmware-2xx-notes)
