Baidu Cleaner claims to improve computer performance in a new unique way by utilizing large-scale cloud computing. Baidu Cloud stores huge amounts of information from web pages with the intent of allowing Baidu users access to only the necessary data for each page at an efficient pace. By using Baidu's own proprietary data, baidu cleaner identifies unwanted files and removes them from the user's computer. Once removed, the old data is automatically placed back into the baidu cloud to allow the file to be retrieved at a later time.
The startup items in your computer also contribute to making it slow. Baidu Cleaner takes a similar approach in minimizing startup items in optimizing your computer performance by identifying unwanted apps that take up a lot of space during start-up. After identifying these unwanted programs, the baidu cleaner goes ahead and deletes it or replaces it with a better application. This ensures that when you need the program, it is readily available and you don't have to hunt around endlessly for the program.
