Mac does not need any application like "CleanMyMac".
Install all system,applications and security updates released by Apple.
Restart the computer once in a while.

OS X requires no periodic "maintenance."
Caches rarely, if ever, need to be "cleaned." Cleaning them periodically will slow your Mac. If you ever get a corrupt cache, just manually remove it from the caches folder or use something like OnyX. I have OnyX on my system, but haven't opened it since Snow Leopard. No need.
Deleting the unnecessary languages from an app may disable the app. Yes, it is poor programming, but it does happen. The space saved is almost meaningless.
Logs are "rotated" periodically by the OS. No need to do it yourself. In very rare cases a log file will run away, but I haven't seen that since Snow Leopard. If you see that (due to continuous loss of disk space), just find the log and delete it. The Console will show a near infinite number of repeating messages generated by some program or process. Fix the process and delete the log file.

Barney-15E said everything in detail.
Ignore all ads that pop up when you visit any website.
Some of these apps are trouble makers.
Keep a backup and install updates when Apple releases updates.

CleanMyMac isn't a totally useless program but it doesn't make my must have list or even my good to have list. Its functions break down into three categories: those already done by the OS automatically (clean caches and log files), those that have some benefit but can be dangerous too (remove unnecessary languages and universal binaries), and useful and not dangerous but not necessarily needed (delete applications).
An applicatioin that deletes applications can be had for much less than CleanMyMac.

I see. So I will just ignore their ads.
Broadly speaking you should ignore all ads for such junk. The more ad placements you see, the more you should ignore them. They are selling snake oil. Don't buy it, even if it's "free". Recovering from the potential damage they can cause will cost you in lost time at best, lost money and data at worst.
There is no program with the intelligence to automatically identify and eradicate extraneous files safely. There is no way for them to discriminate between superfluous files that may be safely deleted and required system components that must not be deleted.
It is nearly impossible for a user to inflict such damage using normal methods.
