+Vacuum send_command allows three parameters:
+
+- entity_id
+- command
+- params - optional
+
+If params are not provided it sends command as payload to MQTT send_command topic.
+If params are provided service sends json as payload with such structure:
+```
+{
+  'command': 'command',
+  'param1-key': 'param1-value'
+}
+```
+
+Service trigger example:
+```
+- alias: Push command based on sensor
+    trigger:
+      - platform: state
+        entity_id: sensor.sensor
+    action:
+      service: vacuum.send_command

 MQTT topic: `vacuum/send_command`
 
-MQTT payload for `send_command` can be an arbitrary value handled by the vacuum's MQTT-enabled firmware.
