Code Cleanup provides two default cleanup profiles - Reformat Code and Full Cleanup - for performing common tasks. They provide the advantage of using Code Cleanup right away, but you cannot edit them. If you need custom cleanup, you can create your own custom profiles for performing specific tasks. See Creating Custom Profiles for guidelines.
The Reformat Code profile only modifies code formatting according to settings configurable in Code Editing | [Language] | Formatting Style pages of ReSharper options. That is, Reformat Code affects blank lines, layout of braces, line breaks, wrapping, spaces, indentation, aligning multiline constructs, and a number of other formatting options.
Full Cleanup is a lot more powerful profile as it complements code reformatting with additional actions. Specifically, it removes code redundancies, converts properties with backing fields to auto-properties, makes fields read-only if possible, arranges 'this' qualifier, and performs a number of other tasks (see table below).
