I knew that you would ask this question - that's why I did not describe those features

You will probably be amazed, but CleanMyMac has quite a lot of unique things up its sleeve. It has absolutely new device cleanup capabilities, that allow you to remove any service files from any external devices.
You will probably ask: Why do I need that?
Aha
For example, my in-car mp3 with USB-support treats ALL the service files as corrupted media files, which causes a lot of confusion in tracks. There is usually a huge number of resource fork files and .DS_Stores in all the folders with your music. Secondly, you will never make your Windows-friend 'faint' when he uses your USB-Stick, because lots of people think that they have a virus when they see Mac OS service files on Windows. Well, it is just a couple of cases where this feature is useful.
Now, Application Removal. Yes, there are some solutions that also do that, but, after an extensive research, we have found out that there were no apps that could analyze packages. This is why CleanMyMac has a very exquisite package analyzer. Most of our users don't even know about that, because it is just a part of Application Uninstaller, but this is what makes this feature MUCH better than in any other apps.
The same story repeats when we deal with leftovers. CleanMyMac does a great job of locating files that are related to the apps you have already trashed before.
Well, I won't comment on some really useful usability features that are not available in other solutions, but if you give CleanMyMac a proper test, you will know what I am on about
That is related to trash status monitor, automatic device cleanup, etc.
Even with all that said, I am sure that our dev-guys would be able to continue the list a lot further. In general, CleanMyMac does a lot of new things and it does a bunch of 'old' things better and safer.
