The Xiaomi Mi Home and Roborock series of robot vacuum cleaners have become an integral part of the modern smart home, taking on the routine of daily cleaning. Many owners mistakenly believe that the device only needs attention when it starts making strange sounds or sucking up dust worse. However, regular maintenance is not just a way to extend the life of the gadget, but also a guarantee that the air in your home will remain clean.
Cleaning frequency is directly dependent on the intensity of operation and indoor conditions. If you have pets or long-pile carpets, the maintenance schedule will be significantly different from an apartment with smooth laminate and no molting pets. Ignoring the simple hygiene rules of the device can lead to engine overheating, electronics failure and unpleasant smell.
In this article, we will discuss a detailed maintenance schedule, explain why sensor cleaning should not be ignored, and explain how often to change consumables. Proper care of HEPA filters and side brushes will ensure stable navigation and powerful suction over the years.
Basic service schedule: daily and weekly procedures
The bulk of the maintenance work of Xiaomi’s robot vacuum cleaner falls on the user’s shoulders in the first days of use until the habit is developed. The minimum level of maintenance involves emptying the garbage container after each cleaning or every other day if the space is small. An overcrowded container is the first reason for the reduced efficiency of suction and overloading of the engine.
Once a week, attention should be paid not only to garbage collection, but also to the primary cleaning of filters. HEPA-The filter, which traps the smallest particles of dust and allergens, should not be washed with water more than once a month, but you need to knock out the accumulated dust from it regularly. Some models have washable filters, but they must be thoroughly dried for at least 24 hours before installing it back.
Also, weekly inspections require side brushes, which often wrap animal hair, threads and hair, which puts additional strain on the motor of rotation, and if you ignore this element, the brush can skew or stop rotating altogether, leaving dust at the boards.
⚠️ Warning: Never use a robot vacuum cleaner without a filter installed.Ingestion of fine dust inside the engine can cause permanent damage and loss of warranty.
Monthly maintenance: deep cleaning of major nodes
A more thorough review of the device should be carried out once a month, during which time it is recommended to completely remove the device. HEPA-filter and, if the design allows, gently wash it under cold water without the use of detergents.
Special attention during this period should be paid to the main brush (wall). Even if it appears to be clean, small fibers may be stuck between the bristles, which eventually compress. It is convenient to use scissors or a special blade, often complete with the device. Cleaning the end bearings of the brush from wound hair is also mandatory, as they are a frequent cause of jamming.
Remember to wipe the body of the device and the wheels. Dust deposited on sensors and wheels can impair the patency and accuracy of navigation. Use a slightly wet, well-pressed cloth to wipe. Use aggressive chemistry or abrasive materials is prohibited.
💡
For removal of contaminants from the plastic case, use a microfiber soaked in a weak soap solution, but avoid getting moisture into the sensor holes.
Quarterly cleaning: sensors, wheels and hard-to-reach places
Every three months, it's time for the cleaner to do the cleaning, and the focus shifts to sensors and wheels, and pollution sensors next to the suction hole and the perimeter obstruction sensors can be covered with a thin layer of dust that you can't see, which causes the robot to misjudge pollution or stop before imaginary obstacles.
The wheelbase is another critical node. Over time, the axis of the wheels will wind hair that penetrates deep into the mechanism. This can cause one of the wheels to stop spinning and the robot to start driving around or getting stuck.
During the same period, it is recommended to inspect charging contacts. Oxidation or contamination of contacts on the robot and the docking station can lead to problems with charging.

Replacement of consumables: terms and signs of wear
Even with perfect care, consumables tend to wear out. Filters lose bandwidth, brushes wear off, and sponge elements deform. Xiaomi and Roborock recommend replacing the main filters every 2-4 months, and side brushes and the main brush every 6-12 months depending on the intensity of use.
The main indicator of the need to replace is often the device itself or the application. Many modern models analyze the airflow resistance and tell the user to change the filter through the notification in the Mi Home application. Ignoring these signals leads to the engine running with overload, trying to compensate for the lack of traction.
Using non-original consumables can be cost-effective, but it is worth carefully monitoring the quality of the filtration. HEPA-filters can pass fine dust back into the air, negating all the benefits of cleaning.
| Component | Frequency of cleaning | Time of replacement | Signs of wear and tear |
|---|---|---|---|
| Dust container | After every cleaning. | When damaged | Cracks, chips. |
| HEPA-filter | Once a week (kick out) | 2-4 months | Darkening, deformation |
| The main brush | Once a week. | 6-12 months | Brushing snails, bearing wear |
| Side brush | Once a week. | 3-6 months | Curvature, lack of bristles |
| Sensors and wheels | Once a month | Not required | Pollution, hair coiling. |
Seasonal maintenance and preparation for long downtime
If you plan to not use a robot vacuum cleaner for a long time (for example, going on vacation or to the country), you need to properly preserve the device. The most important rule is that the dust container should be completely empty, and the filters should be thoroughly cleaned. The dust left inside can become clingy and difficult to remove, and also emit a smell.
The battery also requires attention. It is not recommended to leave the device in a dock with a fully charged or fully discharged battery for more than a month. The optimal charge level for storing lithium-ion batteries is 50-60%. If the robot will stand idle for several months, it is better to disconnect it from the network and put it on the shelf in a cool dry place.
Before you start again after a long period of idleness, be sure to check the condition of all moving parts. The wheels could "lay down", and the brushes could form dust. A few cycles of idle work will help develop mechanisms.

Common Mistakes in Maintenance of Xiaomi Robots
In an effort to make cleaning perfect, users often make mistakes that can cost the device life. One of the most common is to try to wash the filter or wipe the sensors with a wet cloth without further drying. Water trapped inside the case or in the motor causes a short circuit that is 99% warranty-free.
Another mistake is the use of aggressive cleaning products: Alcohol-containing liquids, solvents or abrasives can damage plastic, make it cloudy (critical for sensors), or eat rubber seals. Regular water and microfibers are enough to care for Xiaomi equipment.
Also, don’t ignore software updates, which often include algorithms for optimizing motor performance and navigation, but updates should only be made on stable charging and Wi-Fi connections.
⚠️ Warning: Do not lubricate the wheels and brush axles with oil or silicone lubrication. The lubricated surface will be filled with dust and wool, forming solid lumps that will block the mechanism.
How the Mi Home app helps with maintenance
Xiaomi’s ecosystem provides powerful tools to monitor the condition of the device. In the Mi Home or Roborock app, you can find detailed cleaning statistics and the residual life of filters and brushes. The app automatically calculates the approximate replacement time based on the actual operating time of the motors.
And you can also do diagnostics through the app, and if the robot starts to behave strangely, checking the error logs in the app will help you figure out which node you're looking for, and it can show wheel-stuck errors, laser sensor errors, or fan problems.
Regular synchronization and smart scripting allow you to automate cleaning reminders, so you can set up a script that will send a notification to your phone every two weeks reminding you to check the filters.
💡
Timely replacement of consumables and cleaning of sensors prolong the life of the robot vacuum cleaner 2-3 times, maintaining the suction power at the factory level.
