The automation is facilitated through a smart-contract on the blockchain. Users can deposit their assets into the smart-contract/vault and it will automatically start earning on a weekly basis. Apart from the obvious advantage of automatization, another advantage is the saving of gas. Once the assets are deposited, there is no further action required from the user, until he wants to redeem his returns. Transactions from all users of the vault are pooled together, saving a lot of gasfees.
