Vacuum clean segment

The Vacuum clean segment action starts a Xiaomi robot vacuum cleaning one or more segments. A segment is a room that the vacuum has mapped, identified by a number. To find out which numbers map to which rooms, see Retrieving room numbers.

Using this action from the user interface

If you prefer building automations and scripts visually, Home Assistant walks you through this action step by step. You pick what to target, tweak a few options, and save. No YAML knowledge required.

To clean a segment from an automation or a script:

1. Go to Settings > Automations & scenes.
2. Open an existing automation or script, or select Create automation > Create new automation.
3. If you’re setting up a new automation, add a trigger in the When section. Scripts don’t need a trigger. They run when something else calls them.
4. In the Then do section, select Add action.
5. Select what you want to control. Under By target (see Targets), select the Xiaomi robot vacuum you want to control.
6. From the actions shown for that target, select Vacuum clean segment.
7. Enter the Segments to clean.
8. Select Save.

Using this action in YAML

If you work directly in YAML, or you want to know exactly what Home Assistant does under the hood, this section has the technical reference. It lists the field names you use in YAML, their types, and which ones are required.

In YAML, refer to this action as xiaomi_miio.vacuum_clean_segment. A basic example looks like this:

action: xiaomi_miio.vacuum_clean_segment
target:
  entity_id: vacuum.xiaomi_vacuum
data:
  segments: [1, 2]

This cleans segments 1 and 2 on vacuum.xiaomi_vacuum. To clean a single segment, pass a single number, such as segments: 1.

Options in YAML

Good to know

• To clean a room more than once, repeat its number in the list. For example, segments: [1, 1] cleans segment 1 twice.

Targets of the action

This action requires a target. The target is the object of the action. You can point the action at a single entityAn entity represents a sensor, actor, or function in Home Assistant. Entities are used to monitor physical properties or to control other entities. An entity is usually part of a device or a service. [Learn more], a device, an area, a floor, or a label, and Home Assistant will run the action on every matching vacuum entity behind that target.

• Entity: one specific vacuum entity, such as vacuum.living_room.
• Device: every vacuum entity that belongs to a device.
• Area: every vacuum entity in a room or area.
• Floor: every vacuum entity on a floor.
• Label: every vacuum entity that shares a label.

You can also select different target types in one action. For example, you can add a specific entity and an area as targets in the same action to run the action on both of them at once.
