apt clean β cleans the packages and install script in /var/cache/apt/archives/ (removes all stored archives in your cache)
apt autoclean β cleans obsolete deb-packages, less than clean (removes all stored archives in your cache for packages that can not be downloaded anymore (thus packages that are no longer in the repo or that have a newer version in the repo))
apt autoremove β removes orphaned packages which are not longer needed from the system, but not purges them, use the --purge option together with the command for that.
apt --purge autoremove β remove config files and (more important as it cleans dead subdirectories from the documentation tree) entries from /usr/share/doc.
