What is the most recommended Mac cleaner software?

For completeness sake

Never install any app that claims to "tune up", "speed up" or "clean up" your Mac. These apps exist for one reason: to separate the unwary and inexperienced user from their hard-earned money. At best they do very little, at worst, they can damage your OS installation and cause far more problems than they "solve".

Any Third Party Applications that will interfere with the normal operation of the OS, alter, modify, remove or delete or attempt to do so is an invitation for disaster and may require a Reinstallation of the OS.

This includes AntiVirus, Disk Cleaners, Disk Optimizes, UnInstaller etc.

And this will include one by the acronym name CMM - as a Testament to the issue this specific Application can do - read some of the first 600 Posting here https://discussions.apple.com/search?q=cleanmymac

The The Built in Security  is all that is required.

Do not use any third party app that claims to clean, manage, protect, etc.

Such apps are not needed and they may cause problems.

Why do you think you need a third party software "cleaner"?

The most recommended cleaner app is your 🧠 and "None."
