+
+```yaml

+data:
+  command: reset_waste_drawer
+```
+
+### set_sleep_mode
+

+| enabled    | bool   | yes                                             | Set to true to enable and false to disable.                                                                                                                                                                                                                                                                                                              |
+| sleep_time | string | Required if the param `enabled` is set to true. | Time at which the unit will enter sleep mode and prevent an automatic clean cycle for 8 hours. This param uses the 24-hour format string `%H:%M:%S`, with seconds being optional, and is based on the timezone configured for your Home Assistant installation. As such, `10:30:00` would indicate 10:30 AM, whereas `22:30:00` would indicate 10:30 PM. |
+
+Example of setting the sleep mode to begin at 10:30 PM.
+
+```yaml
+service: vacuum.send_command
+target:
+  entity_id: vacuum.litter_robot_litter_box
+data:
+  command: set_sleep_mode
+  params:
+    enabled: true
+    sleep_time: "22:30:00"
