The best and most obvious trait CleanMyPC embodies is to keep your computer secure and safe, especially in an era where viruses and other malware are plaguing PC owners everywhere.
Though it's been a while since I've used CleanMyPC, the biggest dislike I have is the price. You can use different free services (though not as secure) to clean your computer, and there's even a built-in client that will allow you to clean hard drives and etc. without having to shell out the money for something like CleanMyPC.
Understand when using CleanMyPC that like most platforms, you'll need to make a purchase before having complete access to all of its capabilities. As my experience was only a trial portion of the platform, I can't speak to how well it might serve a company that implements after making the purchase. Of course, that purchase will help meet the needs of the organization better than a trial. All of this is to say that it seems like a solid platform for needing to clean your PC. What more than likely makes this platform stand out over others is its ability to keep your information secure, which may be worth the price of admission alone.
Back when the pricing wasn't as steep, CleanMyPC kept everything clean and secure. However, I'm not currently using CleanMyPC due to the pricing, and the availability of other clients that can solve the same problems for free or a fraction of the price of CleanMyPC.
