If you just want to delete the app, drag the. You also don't need such apps for app removal, since no such app does a thorough job of finding and removing files/folders related to deleted apps. Among other things, it has its own maintenance scripts that run silently in the background on a daily, weekly and monthly basis, without user intervention.
macOS does a good job of taking care of itself, without the need for 3rd party software. Many of these tasks should only be done selectively to troubleshoot specific problems, not en masse as routine maintenance. In fact, deleting some caches can hurt performance, rather than help it, since more system resources are used and performance suffers while each cache is being rebuilt. These apps will not make your Mac run faster or more efficiently, since having stuff stored on a drive does not impact performance, unless you're almost out of drive space.

Most only remove files/folders or unused languages or architectures, which does nothing more than free up some drive space, with the risk of deleting something important in the process. You don't need "cleaner" or "maintenance" apps to keep your Mac running well, and some of these apps can do more harm than good. Whether is spyware or not (I may be mistaken about the spyware part), I would not recommend using CleanMyMac or any similar apps.
