Knockout rosebushes are what is known as "self-cleaning" rosebushes. It is not required to dead head them to get them to bloom again. It is actually discouraged to dead head them as doing so might well prune off the next bloom head growth that has already begun. This is also true of the Homerun series of roses by Weeks Roses. You can certainly pull off all the old dry petals to keep things looking tidy but that is all that is needed. Keep them watered and fed and they should be good to go.
