Owners of Xiaomi, Redmi and POCO smartphones often notice a system application with a broomstick icon on their desktop or in the tool folder, which is called Cleaner. This is a built-in optimization tool that is by default present in the shell of MIUI and the new HyperOS. Many users ignore it, considering it as unnecessary software, but a correct understanding of the operation of this module helps to significantly extend the life of the device.
The program’s primary goal is to free up RAM and internal memory, as well as remove junk files left over from other applications. Unlike third-party counterparts, which are often overloaded with advertising and require unnecessary permissions, Cleaner Xiaomi is integrated deep into the system, allowing it to safely remove cache without risking damaging important system files or disrupting critical services.
In this article, we will discuss the functionality of the cleaner in detail, explain the difference between fast and deep cleaning, and also consider hidden settings, which not everyone knows about. Understanding the principles of this tool will allow you to maintain high performance of the gadget without the need to install heavy third-party software.
Main functions and purpose of the annex
The Cleaner app in Xiaomi’s ecosystem is a comprehensive memory manager, which is designed to scan the file system for temporary files, residual debris from remote programs and duplicates, and analyzes the memory in the background, and the system itself prompts the user to clean when the amount of free space falls below a critical level.
It also works as a task manager, and it enforces the closure of background processes that consume CPU and battery resources, and this is especially true for budget models where RAM is limited, and unlike third-party solutions, the system cleaner has priority access to process closure, which makes it more efficient.
An important feature is the presence of a built-in antivirus, running on the basis of engines from Avast or AVL (Regular scanning allows you to identify potentially dangerous APK-files and block malware from accessing contacts or bank data.
- 🧹 Automatic deletion of cache and temporary advertising files.
- 🚀 Accelerating the system by closing the background applications.
- 🛡️ Scanning for viruses and malicious installers.
- 📦 Managing installed applications and removing unused software.
Interface Discussion: Quick and Deep Cleaning
When you start an app, you see two basic modes of operation that often raise questions: Quick Clean is a surface scan that takes a few seconds. It finds browser cache, gallery image sketches, and application installer packages, which is safe for daily use and does not require deep immersion in settings.
Deep Clean is a more powerful tool that requires user attention, which analyzes large files, rarely used apps, similar photos and screenshots, and it is important to be careful here, as the system can tag files that you forgot in the download folder, but still need to be deleted.
⚠️ Note: When using Deep Clean, carefully check the list of files marked for deletion. PDF or working presentations as “big files” not used in a long time.
The interface is divided into logical blocks, which makes navigation easier. You can separate clean music, videos, documents or other types of information. APK-This gives you flexibility: for example, you can remove old game installers, but save downloaded music for offline listening.

Application management and removal of duplicates
One of the hidden features of Cleaner is the management of application packages. Uninstall in this tool allows you to quickly remove several programs at once, which is more convenient than doing it through the standard Android settings menu. This is especially useful after buying a new phone when you need to remove preinstalled software that you do not plan to use.
Also worth noting is the function of searching for duplicate photos. Cameras of modern Xiaomi often take series of pictures or save photos in different resolutions. Cleaner finds identical images and suggests leaving only the original, removing copies. This frees up gigabytes of storage space without losing the quality of the albums.
For advanced users, the Battery feature is available, which shows power consumption statistics and allows you to close the “gluttonous” applications that drain the battery in the background. While this is not a full-fledged replacement for the battery menu, the tool is great for quickly diagnosing energy leaks.
- 📱 Massive removal of unnecessary apps with one touch.
- 📸 Finding and Deleting Same Photos and Screenshots.
- 🔋 Monitoring applications that consume battery power.
- 📂 Sorting files by type for easy management.
Setup of automation and exceptions
To avoid manual cleaning every time, you can activate automatic mode in Cleaner settings. To do this, go to the application menu (three dots or gear) and find AutoClean. Here you can set the frequency, for example, once every 3 days or when the memory is 80% full.
The critical step is to set exceptions, so if you're working with heavy files or using messengers to transfer documents, make sure to add those folders to the "Ignore" list, otherwise useful information can be deleted in the next automatic cleaning.
How to add an exception to Cleaner?
You can also turn off garbage notifications if they annoy you in the settings, but you can’t completely turn off monitoring, as you may miss the moment when the free space runs out, which will cause a big drop in the performance of the entire system.
| Parameter | Recommended value | Impact on the system |
|---|---|---|
| Autocleaning frequency | Once every 3 days | It supports stability, does not load the processor |
| Notifications | Included. | Timely warning of shortage of space |
| Antivirus | Auto-renewal of bases | Protection against new threats in real time |
| Memory (RAM) | Blocking important | Prevents the retrieval of the desired applications from memory |
Differences between MIUI and HyperOS
With the release of the new HyperOS operating system, Cleaner received a visual update and some functional changes. The interface became more minimalistic, and the scanning speed increased due to the optimization of file system algorithms.
In HyperOS, the cleaner is more integrated with security and device health, and it not only deletes files, but also analyzes the overall health of the smartphone, offering comprehensive optimization solutions. In the old MIUI, the functionality was more disparate and often required switching to different menus.
Older MIUI users may notice a difference in how the antivirus module works. Newer firmware updates the databases more frequently and runs faster. If you have an older model that doesn't get HyperOS, Cleaner's functionality will remain at the level of the latest available MIUI, which is still quite enough for basic tasks.
⚠️ Note: When updating with MIUI On HyperOS, exception settings in Cleaner may reset. be sure to check the list of ignored files after the system update so you don't lose important data on the first automatic clean.
Frequent questions and troubleshooting
Despite its simplicity, users often have questions regarding the application, one of the most common ones being, “Why doesn’t the space vacate after cleaning?” This can happen if the cache quickly accumulates again (for example, due to active use of Telegram or TikTok) or if deleted photos remain in the gallery basket.
Another problem is that the phone is constantly notified that it is “contaminated” right after cleaning, which can be a sign that a particular application is working aggressively creating temporary files, in which case it is worth checking the settings of the problematic application or limiting its background activity.
💡
If Cleaner shows that garbage is 0MB, but the phone is slow, try restarting the device.This will reset system processes and often solve the problem without deep cleaning.
It’s also worth remembering that a cleaner is not a panacea for all ills. If a smartphone is slow due to hardware wear or overcrowded memory (taken 98-99%), no software cleaning will drastically fix the situation, in which cases you need to manually delete heavy files or reset to factory settings.
💡
Xiaomi’s system cleaner is a safe and effective tool for keeping files in order, but it doesn’t replace manual storage management when there’s a critical shortage of space.
