Very easy to use, no set up guide needed. It finds unnecessary files every time Reclaim is clicked and scanned, which I love. Washing Machine does a very in-depth search into the caches each time I scan and it gets rid of that junk so my Mac runs faster and better. It’s nice to choose what you want to clean or scan when you choose Reclaim, Duplicates, or Organize and finally.. I love the look, the design, and the performance of the 2014 Washing Machine!
