Baidu Cleaner for Windows

Keep your PC running smoothly

If you use your computer a lot and rarely check what’s accumulating on it, temporary files, leftovers from uninstalled programs, and other clutter can slow things down. Baidu Cleaner helps you remove that buildup quickly and with minimal effort, so your machine stays responsive and organized.

One-click scans and a simple interface

Baidu Cleaner offers a clean, minimal interface that’s easy to use even if you’re not technical. For users who want a hassle-free cleanup, the main screen provides a Full Scan button that launches a comprehensive sweep of your system. When the scan finishes, the app lists discovered junk so you can decide which items to delete or keep.

Real-time maintenance (Clean Genius)

The Clean Genius feature runs continuously in the background, watching key areas of your system for accumulating junk. When it detects unnecessary files or cache building up, it can remove them automatically, keeping your PC optimized without regular manual intervention.
