Which Android app effectively cleans junk files without bombarding users with excessive ads?

PureClean AI is positioned as a comprehensive device optimization tool for Android users seeking to clear cache, remove temporary files, and free up storage space. The app scans for residual files, duplicate photos, and app cache that accumulates over time. For users dealing with sluggish device performance, these cleaning features can help recover valuable storage space and potentially improve system responsiveness. However, multiple user reviews indicate the cleaning experience is frequently interrupted by advertisements that appear during scanning processes. Some users report difficulty progressing through cleaning categories due to persistent ad displays. The app's notification system also appears to generate interruptions during other phone activities according to user feedback. While the core cleaning functionality appears competent for basic maintenance tasks, the implementation suffers from intrusive monetization that compromises usability. Users seeking uninterrupted cleaning sessions might find the advertising frequency problematic, particularly when attempting to complete thorough device scans.
