Cleaner Toolbox does the cleaner-app standard set: a junk-cache scan, an app uninstaller, a background-process viewer, and a battery info panel. The Play Store listing shows 13 million installs, which is real reach, but the feature set is shallow compared to the names below and the developer page does not link to a parent company or jurisdiction.
The seven Cleaner Toolbox alternatives below cover the same maintenance jobs with deeper scans or recognised vendors. Most are free, the standout is by Google, and the most technical is the open-development SD Maid 2.

Why people switch from Cleaner Toolbox
- Feature set is the floor. Cache scan and process viewer are baseline. The alternatives below add duplicate photo dedup, residual file removal, scheduled scans, and battery savers.
- Generic developer page. No parent company, jurisdiction, or about details. For a tool that needs broad permissions, that matters.
- Background process viewer is largely cosmetic. Android manages process lifecycle automatically. Killing processes from a list typically saves no battery and can briefly slow down apps when they relaunch.
- Frequent ads. Free users see interstitials after most scan completions, which feels heavy for a utility opened in 30-second sessions.
Which Cleaner Toolbox alternative should you pick?
- Files by Google for the lightest cleaner with no ads.
- SD Maid 2 for deep cleaning.
- CCleaner for the classic one-button experience.
- AVG Cleaner for photo dedup and battery saver.
- Avast Cleanup for all-in-one maintenance.
- Norton Clean for trusted-brand free cleaning.
- Phone Master for cleaner-plus-antivirus.
1. Files by Google, lightest cleaner with no ads
Files by Google is the cleanup app Google ships on Pixel and on Android Go. It scans junk, unused apps, duplicate photos, and large videos, and surfaces them in a clean "free up space" view. The whole app is under 15 MB, ad-free, and offloads to Google Drive in one tap.
Where it falls short: no battery info panel or process manager.
Pricing: Free.
Migrating from Cleaner Toolbox: install, grant storage permission, run the cleanup tab.
Download: Google Play
Bottom line: the zero-cost, zero-ad replacement for most Cleaner Toolbox jobs.
2. SD Maid 2, deep cleaning for enthusiasts
SD Maid 2 is the deepest cleaner on Android. CorpseFinder removes orphan files from uninstalled apps, AppCleaner clears caches selectively, Storage Analyzer maps your full filesystem, and Duplicates finds repeat photos.
Where it falls short: dense interface with technical vocabulary. Schedules require Pro.
Pricing: Free for core scans. Pro is a one-time around $10.
Migrating from Cleaner Toolbox: install, grant permissions, run a CorpseFinder scan.
Download: Google Play
Bottom line: the right pick for users who want real control.
3. CCleaner, classic one-button cleaner
CCleaner has been a household name in PC cleanup for two decades. The Android app covers junk scan, residual files, app analyzer, and system info, maintained by Gen Digital.
Where it falls short: free tier shows ads and pushes the Pro upgrade.
Pricing: Free, ad-supported. Pro from around $2 per month.
Migrating from Cleaner Toolbox: install, run scan.
Download: Google Play
Bottom line: the familiar brand swap if name recognition matters.
4. AVG Cleaner, photo dedup and battery saver
AVG Cleaner adds two features other cleaners often gate behind Pro: a smart photo deduper that distinguishes near-identical shots and an app hibernation mode that freezes background activity. Run by Gen Digital.
Where it falls short: ads in the free tier and partial dedup behind Pro on some plans.
Pricing: Free with ads. Pro from around $2 per month.
Migrating from Cleaner Toolbox: install, grant storage and battery permissions.
Download: Google Play
Bottom line: good when photo dedup and battery savers are both on your list.
5. Avast Cleanup, all-in-one maintenance
Avast Cleanup is the broader sibling of AVG Cleaner. The two share an engine, but Avast layers a photo backup, storage analyzer, and battery saver on top.
Where it falls short: limited free trial, frequent upsells.
Pricing: Trial. Pro from around $2 per month.
Migrating from Cleaner Toolbox: install, grant permissions.
Download: Google Play
Bottom line: the all-in-one pick if you accept the upsells.
6. Norton Clean, trusted-brand free cleaner
Norton Clean is the rare cleaner from a major security vendor that is fully free with no ads. It scans junk, finds duplicates, and exposes an app manager. Light, fast, no upsell screens.
Where it falls short: no scheduled scans or deep file analysis. Updates are infrequent.
Pricing: Free.
Migrating from Cleaner Toolbox: install, run scan.
Download: Google Play
Bottom line: the best brand-name free cleaner with zero ads.
7. Phone Master, cleaner with antivirus
Phone Master is the maintenance app shipped by Transsion (the company behind Tecno, Infinix, and itel phones). It includes a junk cleaner, a process killer, a battery saver, and a basic antivirus scanner. It is widely installed in emerging markets thanks to OEM presence.
Where it falls short: ad density is high and some scans push paid upgrades. Antivirus is basic compared to dedicated security apps.
Pricing: Free with ads. Pro from around $2 per month.
Migrating from Cleaner Toolbox: install, grant permissions, run a scan.
Download: Google Play
Bottom line: pick this only if you want cleanup plus a light antivirus in one app.

FAQ
What is the best free cleaner app for Android?
Files by Google is the strongest free pick: zero ads, made by Google, light on resources, and covers the essentials. For deeper control, SD Maid 2 is the enthusiast choice.
Does killing background apps save battery?
Usually not. Android manages process lifecycle automatically. Force-stopping apps can briefly slow down their next launch and very rarely improves battery life. Use scans and deletion of large files for real wins.
Are phone cleaner apps safe?
Cleaners from Google, Norton, Avast, AVG, and CCleaner are generally safe but request broad permissions. Read what each permission unlocks. Generic small-developer cleaners with no parent company and no privacy policy should be approached with caution.
Will a cleaner app really free up space?
The most reliable wins come from deleting duplicate photos, large unused videos, and residue from uninstalled apps. App cache, by contrast, gets rebuilt within hours. Files by Google and SD Maid 2 both do the deeper scans where space actually appears.
