Xiaomi’s robot vacuum cleaners and the Mijia ecosystem are well-deservedly considered market leaders due to their clever design and intelligent navigation algorithms. However, even the most advanced technology requires regular and proper maintenance to maintain peak performance. Many owners mistakenly believe that the device works autonomously and requires no human attention, except to empty the container.
In reality, ignoring basic hygiene rules leads to rapid engine wear, battery capacity drops and, as a result, reduced cleaning quality. Dust, pet hair and small debris can block critical nodes in just a few months of operation. In this article, we will detail how to care for a robot vacuum cleaner shaomi to serve you for many years.
Regular cleaning of the dust collector and filter system
The heart of any filtration system is HEPA-A filter that traps the smallest particles of dust and allergens, which in Xiaomi models is usually located at the top of the garbage container. 2-3 cleaning, especially if there are animals in the house, washing with water is allowed, but only after careful drying during the period of time. 24 or the moisture will get into the engine.
The garbage container itself also requires attention. Small dust often accumulates inside, which sticks to the walls due to static electricity. It is recommended to wipe the inner cavities with a wet cloth without using aggressive chemistry. Pay special attention to the inlet through which air is sucked in, which often forms dense plugs of dust.
⚠️ Note: It is strictly forbidden to operate a robot without an installed HEPA-Fine dust will enter the engine turbine, causing it to overheat and fail.
To wash the filter, use only cold water. Hot water can deform synthetic fibers, and the filter will lose its properties. If the filter is greyed or blackened and does not wash, it must be replaced with a new original or quality counterpart.
💡
Use a soft brush to remove dust from the surface HEPA-filter before each wet cleaning - this will prolong its service life.
Maintenance of main and side brushes
The main brush (wall) is the main working element that sweeps debris from carpet villi and smooth floors. Over time, its ends and central axis are wound with hair and wool, creating a tight cocoon. This puts additional stress on the motor of the brush and can lead to a break in the belt or break the gears.
Side brushes also require inspection, they are attached to plastic holders that can deform over time, and if the pile of the side brush is severely erased or broken, the cleaning efficiency along the walls and in the corners drops dramatically, in which case the side brushes are replaced because they are consumables.
It is important to check the bearings on which the main roller rotates. If they are clogged with dirt, the brush will rotate unevenly or with a characteristic hum. Use tweezers or scissors to clean, carefully removing all the threads. Remember to lubricate the axes of the roller with a drop of silicone lubricant every six months for silent operation.
☑️ Weekly brush maintenance
Caring for wheelbase and navigation sensors
The wheels of a robot vacuum cleaner are its legs, and they take the load when moving around the apartment. The treads of the wheels are constantly stuffed with dust, wool and small debris, which can lead to slippage and navigational errors. The robot can start towing on site or build the wrong map of the room.
Special attention should be paid to optical sensors and lidar (if the model is equipped with a turret at the top), fall sensors (located at the bottom along the perimeter) and collision sensors should be perfectly clean. Dust on the sensor lenses leads the robot to "think" that there is a wall ahead, or, conversely, may not notice the step and fall from it.
The lidar rotating on the top panel is very sensitive to contamination. Rub it with a soft microfiber without pile. If the laser rangefinder has a layer of dust, the map of the room will be distorted, and virtual walls may not work correctly. Also check the charging contacts on the bottom panel of the robot and on the base - oxidation or dirt on them will lead to problems with charging.
What to do if the robot is stuck?
Hygiene of the wet cleaning module
Xiaomi’s wet cleaning module is a water tank and an electronic pump (or a flowing system) that must be drained after every wet cleaning. Stagnant water is the perfect environment for bacteria to multiply and mold to appear, which will cause a bad musty smell on the next cleaning.
The wet cleaning cloth needs not only to be washed, but also periodically disinfected or replaced. Over time, the fabric loses its absorbent properties and wears off. Only use special microfiber wipes designed for your model, as too fuzzy fabrics can clog the water supply system.
Once a month, it is recommended to wash the water tank itself with a weak solution of vinegar or citric acid to remove scale, especially if you have hard water.This will prevent clogging of the micro-holes through which water is supplied to the floor. After washing, be sure to dry the tank in the open.
⚠️ Warning: Never add conventional liquid detergents, foaming compounds or chlorine to the water tank. The foam can damage the pump, and aggressive chemicals can eat the rubber seals and plastic parts of the tank.
Comparison of models and their features of service
Different generations of Xiaomi and Roborock robot vacuum cleaners have design differences that affect their care. For example, models with laser lidar require a more careful attitude to the top panel, while models with a camera (vSLAM) need perfect lens cleanliness. Understanding these nuances will help avoid typical errors.
The table below shows a comparison of the main nodes and the frequency of their maintenance for popular series of robots.
| Component | Series S (S50, S55) | Max Series (Mijia 1C, Vacuum-Mop) | Pro/V Series (LDS with camera) |
|---|---|---|---|
| Filter | HEPA E11, washing once every 2 weeks | HEPA E11, wash once a week | HEPA E12, washing once every 2 weeks |
| The main brush | Removable, cleaning once a week | Removable, cleaning once a week | Removable, cleaning once every 5 days |
| Sensors. | Laser lidar (wiping) | Optical camera (wiping) | Lidar + Camera (double cleaning) |
| Water tank | Electronic pump | Self-flowing system | Adjustable electronic pump |
As you can see from the table, having a pump requires more attention to water quality and the absence of foreign impurities. Self-fleshing systems are easier to maintain, but can provide uneven moisture when clogging the outlet holes.
Charging station and battery care
The charging base is your robot's home, and it needs care too. The base and robot contacts need to be clean and dry. If you notice a black coating on the contacts, gently wipe them with a dry cotton swab or an alcohol wipe. Poor contact leads to intermittent charging and rapid battery discharge during operation.
There should always be a free zone around the base. The robot needs space to maneuver when leaving and entering the dock. If the area is crowded with things, the robot may not find the base or hit an obstacle when parking, and also make sure that the dust under the base does not accumulate, which the robot will carry around the apartment every time it leaves.
A battery is the most expensive consumable. To extend its life, don't let it run completely deep. If you're away for a long time, you'd better leave the robot on the base (modern models turn off the current when fully charged) or turn it off by charging 60-80%.
The optimal temperature for operation and storage of lithium-ion batteries is from +10 ° C to +25 ° C. Overheating in the sun or working on a cold balcony dramatically reduces the battery life.
Software and firmware updates
Robot care is not just about physical cleaning, it's also about keeping the software up to date. Xiaomi engineers are constantly releasing updates that improve map-building algorithms, optimize battery consumption and correct navigation errors. Ignoring updates can lead to the robot working less efficiently.
You can check for updates via the Mi Home or Xiaomi Home app. Usually, if you have a new version of the software, a notification appears in the device card. Before upgrading, make sure that the robot is charged at least 20% and is located next to the Wi-Fi router for a stable connection.
You can also reset the map of the room in the app settings if the robot starts to "glut" or you have rearranged the furniture. Regular calibration of the gyroscope (if this is provided in the service menu) also helps to improve the accuracy of movement in a straight line.
💡
Regular firmware updates and sensor cleaning are the key to the intellectual work of your robot vacuum cleaner.
