Care for Xiaomi robot vacuum cleaner: the complete guide

Operating smart machines requires not only the right initial setup, but also regular maintenance. Xiaomi’s vacuum cleaner robots, whether the Mijia Vacuum-Mop 2 Pro, Xiaomi Robot Vacuum S10 or earlier versions of the Roborock series, are complex electromechanical devices that combine precision sensors, battery packs and movable components that inevitably become contaminated as they work.

Ignoring the device's simple hygiene rules can lead to poor cleaning, noise, or even major nodes breaking down. Many users mistakenly believe that the robot can work forever without human intervention, but regular cleaning is key to a long life for the gadget. In this article, we'll look at all the steps in caring for your assistant.

The main task of the owner is to ensure the cleanliness of contact groups, navigation sensors and filtration systems. Dust, animal hair and small debris can clog the air channels, which will lead to overheating of the engine. Proper care allows you to maintain the suction power at the factory level even after years of use.

Cleaning of the filtration system and dust collector

The heart of any cleaning is a filtering system, which in Xiaomi robots usually consists of several stages: a prefilter, HEPA-The filter and the main garbage container, and that's where the bulk of the pollution accumulates. HEPA-The filter traps the smallest particles of dust, allergens and mold spores, preventing them from returning to the air.

The regularity of maintenance depends on the intensity of use: if there are pets or carpets in the house, the container should be cleaned after each cleaning.

⚠️ Warning: It is strictly forbidden to use wet dust collectors or wet filters, which can lead to water entering the engine and short circuit of the robot's electronics.

The process of cleaning the prefilter is simple: take it out, knock on the trash can to remove the large dust, and rinse under the tap without using detergents. Dry the filter elements naturally within 24 hours. Using a hair dryer or battery can deform the material's structure, after which it will no longer effectively trap dust.

To extend the service life of consumables, it is recommended to have a spare kit. HEPA-filter (once in) 2-3 The clogged filter creates resistance to air, causing the engine to run at its limits, leading to premature wear and tear.

• 🧹 Shake the main container over the trash can after each cleaning cycle.
• 💧 Wash the prefilter with water only after thorough dry cleaning of large dust.
• ⏳ Dry all filter elements for at least 24 hours before re-installation.
• 🔄 Change. HEPA-filter-in 2-3 month-long active operation.

Maintenance of the main brush and turboblock

The central element of mechanical cleaning is the main brush (turboblock). Xiaomi models have two types of designs: a classic brush with pile and a lilac-free brush with silicone lamellae. Foldy brushes effectively sweep dust out of carpets, but have one major drawback: they constantly wound hair and wool.

The hair that's wound up puts extra strain on the brush engine, and over time, it can cause the drive belt to stretch, or even break the gears of the gears, and you have to flip the robot over, remove the protective grille, and remove the brush shaft, and use the included hook knife or the usual hair removal tweezers.

Special attention should be paid to bearings on which the brush rotates, which often fills fine dust, which mixes with fat and turns into an abrasive paste, which causes creaking and makes it difficult to rotate, regular lubrication or just careful purging of these knots helps to avoid extraneous noise.

If you have a silicone brush, it's even easier to care for, but it requires attention to the ends of the shaft. It's where long hair gets stuck most often, blocking rotation. Don't try to force a blocked brush, which is a surefire way to break the plastic mounts.

• ✂️ Use a special knife from the kit to safely remove hair from the shaft.
• 👀 Check the condition of the bristles: if it is severely worn out, replace the brush.
• 🧼 Wipe the inner chamber of the brush with a wet wipe from the sticky dust.

Care for side brushes and wheels

The lateral brushes are responsible for sweeping debris out of corners and along walls under the main suction zone. They rotate at high speed and are the first to come into contact with large debris. Over time, the bristles wear off and the axles are wound up, and the side brushes are replaced, a consumable procedure that should be carried out as they wear out.

Xiaomi's wheelbase is a complex mechanism with spring-wheeled wheels. Dust lumps, hair and small debris are often clogged between the wheel and the body. This prevents the wheels from rotating freely and springing back, which is critical to overcoming sills and carpets. If the wheels are blocked, the robot can start towing or get navigational errors.

⚠️ Warning: Do not allow water to enter the openings of the wheel modules. lubrication may enter or corrosion of the contacts may occur, which will lead to a failure of the driving system.

To clean the wheels, use a dry toothbrush or tweezers. Gently pull the wheel down (it's spring-loaded) and clear all the dirt around the circle. Also check the condition of the small front rotary wheel. It often gets stuck because of the wound threads, which causes the robot to drive in circles or lose orientation.

Regularly checking the chassis avoids situations where the robot gets stuck in the middle of the room. Mechanical obstacles in the form of coiled hair can block the wheels' spin sensors, and the robot will think that it is getting stuck in the air, stopping cleaning.

Cleaning of navigation sensors and sensors

Xiaomi’s modern robots are equipped with an arsenal of sensors: lidar (LDS), optical floor sensors, infrared obstacle sensors and elevation drop sensors, and pollution of these elements is the most common cause of the device’s “stupid” behavior when it crashes into walls or falls from stairs.

The optical sensors on the bottom panel and around the bumper perimeter need to be wiped with dry soft cloth, and the dust on them creates a fog effect, and the robot stops seeing obstacles. The top lidar also requires attention: dust on the protective glass can distort the map of the room.

Pay special attention to the elevation sensors (usually 4-6 at the bottom perimeter) If they are contaminated, the robot can think that it is on the edge of the cliff, and will constantly move back or spin in place. Clean sensors are the basis of correct navigation.

• 👁️ Clean all black sensor windows with a dry microfiber before each cleaning.
• 🌪️ Carefully remove dust from the lidar window without pressing hard.
• 🧹 Check the cleanliness of charging contacts on the docking station and robot.

If you notice that the robot is moving randomly or is constantly reporting that it's getting stuck, even though the floor is clean, 90 percent of the time, the problem is that it's dirty sensors, and 30 seconds is enough to wipe them, and the device will work perfectly again.

Comparison of models and features of service

Different generations of Xiaomi robots have their own design features that affect care. Older models with gyroscope navigation or chaotic movement require more frequent cleaning of the wheels, as they are more likely to fight against furniture. New models with laser navigation (LDS) are more sensitive to the purity of the upper sensors.

Models with wet cleaning function (for example, Xiaomi Vacuum-Mop) require additional attention to the water supply system, you need to monitor the purity of the nozzles and the state of the electronic pump. Stagnation of water in the tank can lead to scale and mold.

The table shows the average data, but in houses with animals, the frequency of procedures should be increased by 2-3 times, and the wool can clog even the most perfect filter for a couple of cleanings.

Caring for the battery and the charging base

The autonomy of the robot depends on the state of the battery. Lithium-ion cells used in Xiaomi do not like deep discharge and overheating. If you are away for a long time, it is recommended to charge the robot up to 60-80% and disconnect it from the network, although modern BMS (battery management systems) are able to maintain charge.

The charging base is not just a socket; the contacts on the robot and the base oxidize over time, especially in conditions of high humidity (if the robot is washing), periodically wipe the metal plates with a dry cloth or cotton swab dipped in alcohol.

💡

If the robot stopped charging or the charging is interrupted, wipe the contacts on the robot and base with an alcohol wipe. Contact oxidation is a common cause of charging problems.

Don't let the battery run completely to zero. If the robot writes a "Low Battery" error and shuts down, put it on the base right away. Deep discharge can irreversibly reduce battery capacity, and the robot can only clean half of the apartment instead of the whole one.

⚠️ Warning: Do not store the robot vacuum cleaner in an unheated room at temperatures below 0°C. This can lead to degradation of the electrolyte in the battery and its failure.

Also, keep the base clean. The base's junction with the floor often accumulates dust that can get inside the charger. Vacuum around the base regularly to ensure it is cooled and clean.
