Do you mean Rebuilding? Cleanup is the term used in OF for refreshing the current view, for example, to hide completed items. Rebuilding is the term for coalescing a series of separate transaction into a single database state. I believe that OF 1.1 automatically rebuilds the database as all the clients synchronize to a series of transactions.

Or do you mean Archiving? Archiving moves completed items to a separate archive database that isn't sync'd to the phone. Archiving seems to be a work in progress currently.
