| Property | Description | Type | Filling example | Mandatory field |
| Parameters |
| Collection | The collection from which to remove elements with duplicate values. All changes will be saved to the same collection. | Robin.Collection |

Special conditions of use
The original collection is checked for elements with repeating values and returns the same collection but without these elements.
- The comparison may take a register into account - depends on the value of the corresponding input parameter.
- If the element values are the same, but it is an element of a different type, it is not considered a take.
- Empty elements (elements with empty value) of the same type will be considered as doubles and deleted. Empty elements of different types are not considered doubles, so the action will not compare and delete them.
- If the collection has no takes, the action returns the collection unchanged.
- Duplicates are checked only for elements with type "Boolean", "String", "Numeric", "Data-time", "Point coordinates", "Folder path", "File path". Elements with other type are ignored when searching for duplicates
- The modified collection is saved to the original collection.
