All banks usually offer auto-sweep, but these are generally account-specific. Hence one needs to confirm with your bank whether this option is available for your savings or current account or whether you can transfer to an account with a sweep-in facility. For instance, HDFC is a bank with auto sweep facility and the Super Saver account qualifies for the sweep-in feature; as a result, if you currently have a regular savings account, you must switch to the Super Saver account to take advantage of this feature.
