Clean Sweep Master
Overview
Clean Sweep Master is a device maintenance utility designed to clean local storage and monitor system battery health. The application targets standard temp directories and app caches to reclaim storage. However, because modern versions of Android isolate app caches, third-party utilities cannot easily clear these directories without using the system's Accessibility Services to automate manual menu navigation. The application also features a battery diagnostic module that uses Android's BatteryManager API to pull real-time hardware metrics, including battery temperature, voltage, design capacity, and charging status.
One of the application's unique features is its physical speaker cleaning tool. This tool generates high-volume, low-frequency acoustic signals, typically around to , to create physical resonance within the device's speaker chamber. This physical vibration helps push dust and moisture out of the speaker grill. This physical mechanism helps clear debris and restore volume levels.
However, the app's overall utility is significantly degraded by its aggressive monetization model. Clean Sweep Master displays frequent, sequential full-screen video ads that interrupt basic navigation and push users to download companion apps. The developer has acknowledged this heavy ad load, noting that ad revenue is necessary to keep the app free. The app's process management tool can also negatively impact performance. By terminating background processes, it can trigger a cycle of automatic restarts by Android's system scheduler, which actually increases CPU wake-locks and drains the battery. In terms of privacy, the app shares user locations, application activity metrics, and unique device IDs with outside advertising partners without giving users a way to request data deletion.

How does the speaker cleaning acoustic tool work?
The tool plays low-frequency sound waves that vibrate the physical speaker membrane to help displace dust and water.
What battery diagnostic data does the app display?
The diagnostic dashboard displays real-time statistics including battery temperature, voltage levels, current capacity, and estimated remaining run-time.
Why does this utility app require location permissions?
The app collects and shares location data with third-party ad networks to deliver targeted local ads.
Is there an option to remove advertisements?
No, the standard version does not offer a setting to disable ads, as it relies on ad revenue to fund its free operations.
How does the large file cleanup tool categorize files?
The large file tool scans and lists photos, videos, music, and document files larger than, sorting them by size for easy review.
Hot Reviews
Users report that the application is saturated with constant, back-to-back ads that disrupt the cleaning process and feel invasive.
Some reviews note that while they were initially skeptical, the speaker clean feature's loud acoustic frequency successfully cleared dust from their phone's speaker.
Users criticize the app's unclear pricing model, noting that it should be more transparent about which features require additional payments.
Reviews highlight that the app's heavy background processes and ad loading cause the phone to warm up and drain the battery quickly.
