Clean Master clears junk files and surfaces unused apps quickly, which is why it still has a base on older Android devices. The trade-off is loud. Full-screen ads land between scans, the app keeps asking for permissions it doesn’t need to free up cache, and the categorization of “junk” is aggressive enough to delete things you wanted. Users on r/AndroidQuestions and XDA forums keep circling back to the same point: the cleanup works, the experience around it doesn’t.
If you’re looking for Clean Master alternatives that strip the ads, ship cleaner permissions, or just leave you in control of what gets deleted, the field has matured around two camps: clean free-tier apps from major vendors, and lean utilities that do one job well. We tested seven on storage cleanup, RAM management, app uninstall, and large-file discovery, then ranked them on what they actually do without nagging.

Why people leave Clean Master
Ads break every action. Tap “scan”, see an ad. Tap “clean”, see an ad. Tap “back to home”, see an ad. The free experience rewards uninstalls more than it rewards staying.
Permissions feel excessive. Clean Master historically asked for accessibility services, notification access, and device admin permissions for tasks that other cleaners do without them. The behavior keeps showing up in modern reviews on the Play Store.
Aggressive categorization. The “junk” bucket sometimes includes app caches you wanted (offline maps, podcast downloads, recently-viewed photos). Anyone who lost data once to an over-eager clean stops trusting it.
Reputation drag. The original Clean Master from Cheetah Mobile was pulled from the Play Store in 2020 for ad fraud. The brand on Play today is a different publisher, but the association lingers and users searching for safer cleaners look elsewhere.
The alternatives
Files by Google — best for built-in cleanup
Files by Google is the only cleaner Google ships natively, and it shows. The Clean tab surfaces large files, duplicates, screenshots, and unused apps with smart suggestions that don’t touch caches you might want. No ads, no upsell, no permission overreach. It also doubles as a Nearby Share file manager and a basic SD card mover.
Where it falls short: No real RAM management (Android handles that itself), the cleanup suggestions are conservative, and it won’t surface app-specific cache the way SD Maid does.
Pricing:
- Free: Everything
- Paid: Free
- vs Clean Master: Free with no ads, conservative cleanup
Migrating from Clean Master: Uninstall Clean Master, open Files by Google, tap Clean, work through the categories. Setup takes minutes.
Download: Aptoide · Google Play
Bottom line: Pick Files by Google for the cleanest cleanup with zero noise. Skip it only if you want deep cache control.
SD Maid 2 — best for power-user control
SD Maid 2 (also called SD Maid SE) is the cleaner built for people who want to see every file before they delete it. The CorpseFinder spots leftover folders from uninstalled apps, the AppCleaner surfaces cache by app with precise control, and the Storage Analyzer maps your storage like a treemap. The Pro tier adds scheduling and deep filtering.
Where it falls short: The interface is utilitarian and the learning curve is real, the Pro features actually do require Pro, and casual users will feel over their head.
Pricing:
- Free: Core cleanup tools
- Paid: $5.99 one-time Pro
- vs Clean Master: One-time payment, far more granular, no ads
Migrating from Clean Master: Install SD Maid 2, run the initial scans, review the suggestions before accepting. Allow an evening for the first deep clean.
Download: Aptoide · Google Play
Bottom line: Pick SD Maid 2 if you want to know exactly what’s being deleted. Skip it if you want a single-tap clean.
Droid Optimizer — best for all-in-one cleanup
Droid Optimizer by Ashampoo bundles cache cleanup, RAM management, battery optimization, and app management into one ranking-style interface. The daily auto-clean runs in the background and surfaces a points-based summary that gamifies the cleanup loop. For people who liked Clean Master’s all-in-one feel without the worst ads, this is the closest match.
Where it falls short: The free tier still has banner ads, the “RAM boost” feature does what Android already does on its own, and the gamification can feel infantilizing.
Pricing:
- Free: Everything with ads
- Paid: Free (ad-free variant via web download)
- vs Clean Master: Lighter ads, German-engineered, more transparent
Migrating from Clean Master: Install, grant the suggested permissions, run a full scan. About fifteen minutes.
Download: Aptoide · Google Play
Bottom line: Pick Droid Optimizer if you want Clean Master’s feel without Cheetah Mobile’s history. Skip it if ads still bother you.
1Tap Cleaner — best for lightweight cache clear
1Tap Cleaner does exactly what the name says: one tap clears app cache across every installed app, plus call logs, browser history, and clipboard. The install is sub-1MB, the interface is plain to the point of dated, and the Pro tier removes ads and adds automation.
Where it falls short: No file management, no duplicate finder, the UI shows its age, and the Pro upgrade nags users.
Pricing:
- Free: Core cleanup with ads
- Paid: $1.99 one-time Pro
- vs Clean Master: Far smaller install, one-time price, narrower scope
Migrating from Clean Master: Install, tap the clear-cache button, done.
Download: Aptoide · Google Play
Bottom line: Pick 1Tap Cleaner for the smallest cache cleaner you can install. Skip it if you want broader cleanup features.
AVG Cleaner — best for photo deduplication
AVG Cleaner is the strongest in this group at finding duplicate and low-quality photos. The Photo Optimizer flags blurry shots, duplicates, and screenshots from the gallery and offers cleanup in batches. The junk cleaner is competitive with Clean Master, and the AVG brand carries goodwill from its antivirus work.
Where it falls short: The free tier pushes AVG Antivirus installs, the Pro upgrade is annual rather than one-time, and the app is heavier than 1Tap or SD Maid.
Pricing:
- Free: Cleanup with ads
- Paid: $19.99/yr Pro
- vs Clean Master: Pricier on annual, sharper photo cleanup
Migrating from Clean Master: Install, run the photo scan first, then junk and app cleanup. About 20 minutes for a phone with a full gallery.
Download: Aptoide · Google Play
Bottom line: Pick AVG Cleaner if your gallery is the problem. Skip it if you mainly want app-cache cleanup.
Norton Clean — best for no-frills cleanup
Norton Clean is the rare cleaner from a major security vendor that ships completely free with no ads. It clears app cache, residual files, and obvious junk on a single tap, and the interface is the closest thing in this category to a Google-quality app. Brand trust is the main selling point.
Where it falls short: The feature set is narrower than SD Maid, no duplicate finder, no scheduling, and Norton’s mobile presence is shrinking so updates ship slowly.
Pricing:
- Free: Everything
- Paid: Free
- vs Clean Master: Free with no ads, narrower feature set
Migrating from Clean Master: Install, tap Clean. Instant.
Download: Aptoide · Google Play
Bottom line: Pick Norton Clean for a no-ad cleaner with a trusted name. Skip it for advanced cleanup features.
CCleaner — best for the familiar desktop interface
CCleaner brings the same interface millions used on Windows desktops to Android. App manager, junk cleaner, RAM analyzer, and system info sit in one consolidated layout. For users moving from desktop CCleaner who want the same workflow on mobile, the familiarity is the draw.
Where it falls short: The free tier shows banner and interstitial ads, the Premium tier is annual, and the 2024 ownership change to Gen Digital has slowed feature releases.
Pricing:
- Free: Everything with ads
- Paid: $24.99/yr Premium
- vs Clean Master: Pricier paid tier, similar feature set, more consistent UI
Migrating from Clean Master: Install, run the initial analyze step, review and clean. About ten minutes.
Download: Aptoide · Google Play
Bottom line: Pick CCleaner if the desktop CCleaner workflow is what you want on phone. Skip it if ads or the annual price put you off.

FAQ
Do Android phones actually need a cleaner app?
Modern Android handles cache, RAM, and background processes automatically. Cleaner apps mainly help with duplicate photos, leftover files from uninstalled apps, and surfacing unused apps. For new phones with plenty of storage, you usually don’t need one. For older or low-storage devices, a clean utility like Files by Google or SD Maid helps.
What is the best free Clean Master alternative?
Files by Google is the most-recommended free alternative. It has no ads, no upsells, comes from Google, and handles the same cleanup categories. For power users, SD Maid 2’s free tier is the strongest.
Are phone cleaner apps safe?
Cleaners from major vendors (Google, Norton, AVG, Ashampoo) and audited open-source projects (SD Maid 2) are safe. Apps from unknown publishers that ask for accessibility, device admin, or notification access for basic cleanup are red flags. Check permissions before installing.
Does Clean Master drain the battery?
The original Clean Master ran background services that could affect battery on older Android versions. Modern Android limits background activity for non-foreground apps, so the impact is smaller. Files by Google and Norton Clean have no persistent background services.
What’s the difference between SD Maid and SD Maid 2?
SD Maid 2 (SE) is the actively maintained successor. The original SD Maid is in maintenance mode. Use SD Maid 2 for new installs.
Can these cleaners free up space without rooting?
Yes. None of the alternatives in this list require root for standard cleanup. SD Maid 2’s deepest features (system cache cleanup) benefit from root but work without it.
