About housekeeper processing

[newzabbix]

It is a recognition that housekeeper processing can not reduce physical disk usage, but is it correct?
Is there special processing (such as explicit execution of VACUUM etc), and can you reduce disk usage?
Also, housekeeper will issue DELETE, but will you issue DROP and so on?

The housekeeper process does not execute VACUUM, DROP, etc.

Thank you for your response.
In other words, housekeeper only executes DELETE to the DB, and there is no operation that affects disk usage.
