I'd be cautious about choosing such an app though. SD Maid is ok, though when using it you should think about which of its suggestions you actually want to clear: it's a powerful app, and you know what Spiderman's Uncle Ben said about great power...
But a lot of these "system cleaner" apps contain actively undesirable features: task killing/ram cleaning (different names for the same thing) which are not only not needed since about Android 2 but are often actively counter-productive. And of course some of these come from companies whose business model is to steal data from your phone and sell it to whoever will pay (Cheetah Mobile are thost infamous, but far from the only guilty parties).
