Modern cleaning automation devices like Xiaomi and Roborock make life much easier, but they require regular maintenance to maintain high performance. Many owners mistakenly believe that the appliances can work for years without human intervention, but the accumulation of dust, wool and debris in the machinery inevitably leads to a decrease in suction power and a reduction in battery life. Regular cleaning is not just a hygienic procedure, but a necessary measure to prevent damage to expensive nodes.
In this detailed guide, we’ll take you through all the steps of your robot vacuum cleaner maintenance, from emptying the container to washing the sensors. You’ll learn what tools you’ll need, how often you need to maintain it, and what you can’t do to keep your electronics safe. The right approach to Roborock care ensures that the device will work on day one as efficiently as it did in the year it was released.
Before you start disassembling, you need to prepare the workplace. You need a dry, well-lit surface where you can put all the removed parts in order of priority, also stock up on dry soft cloth, a small brush (often included) and, if necessary, scissors to remove wound hair. Never use water or detergents to clean the electronic control board and charging contacts.
Preparation for maintenance and safety
The first step before any manipulation is to complete the current cleaning correctly. If the device is in the process of working, send it to base or press the pause button, and then turn off the power button on the case. This is necessary for the electronics to go to sleep and all active suction processes. Leaving the device on during cleaning can lead to accidental start of the motor, which is traumatic to the fingers.
Turn the robot vacuum cleaner upside down, placing it on a soft surface, such as a towel or mat, so as not to scratch the top plastic panel and sensors. Visually inspect the bottom of the device for large objects that may have been stuck in the wheels or under the main brush. Remove visible debris with your hands or tweezers, acting carefully so as not to damage the rubber elements of the wheels.
💡
Use a dry eraser to clean the contaminated contacts of the charging station and the robot itself – this will improve the quality of charging without the use of chemistry.
It is important to make sure you work in a low-humidity environment.Even a minimal amount of moisture entering the enclosure during maintenance can cause contacts to corrosion or short circuit the next time you turn on.If you have just finished a wet cleaning with a detergent module, make sure all surfaces are completely dry before starting to disassemble dry nodes.
Maintenance of the main brush and side brooms
The centerpiece of the cleaning system is the main brush, which is responsible for knocking out dust from carpets and raking up large debris. In Roborock and Xiaomi models, this knot is usually fixed by two latches or screws, depending on the generation of the device. Remove the protective grille, remove the brush shaft and carefully examine its ends: this is where the hair and threads are most often wound, blocking rotation.
Use scissors or a special scraper knife from the kit to gently cut and remove the wound fibers. Do not pull the hair by force, as this can damage the bearings of the shaft or the brush itself. After mechanical cleaning, wipe the shaft with a dry cloth. If the brush is badly worn out, the pile has become short or cracks on the plastic, it must be replaced, since the cleaning efficiency depends on the condition of the pile.
- 🧹 Regularly check the side blizzards for wear of the bristles - if it has worn to plastic, the blizzard needs to be replaced.
- ✂️ Clean the axis of rotation of the side blizzard from the hair, otherwise the motor may burn from overload.
- 🔄 Change the main brush every time 6-12 months depending on the intensity of use and type of coatings.
☑️ Monthly brush maintenance
The side blizzards also require attention. They attach themselves to a screw or a latch and spin at high speed, sweeping debris towards the center hole. Often the hairs get stuck in the mounting mechanism, creating a beat and noise. Carefully clean this knot with a small brush. If the broomstick is deformed or has lost its elasticity, it will stop reaching the corners, and the quality of cleaning around the perimeter of the room will fall.
Cleaning of the filtration system and dust collector
The filtration system is the lungs of your robot vacuum cleaner. The dust container usually has a fine cleaning HEPA filter that traps the smallest particles of dust and allergens. Take out the container, open the lid and pour the contents into the trash can. Don't knock the container out indoors so that the raised dust doesn't settle back on the furniture and get back into the device.
The filter. HEPA You can’t wash with water unless your specific Xiaomi model’s instructions say otherwise, usually tapping it gently on the wall of the trash can to remove the bulk dust, or using a dry soft brush. Water washing is allowed only for reusable filters-nets, which are installed in front of the main HEPA-After any cleaning, the filter must dry for at least 24 hours in a warm place.
| Type of filter | Cleaning method | Replacement frequency | Can I wash? |
|---|---|---|---|
| Primary grid | Water washing | Every 2-3 months | Yeah, with drying. |
| HEPA filter | Dry brushing | Every 6 months | No (usually) |
| Tank filter (E10) | Replacement | Once a year. | No. |
Notice the state of the mesh that closes the turbine entrance. If it's clogged with fine dust, the suction power drops dramatically, and the motor starts to work with overload, which reduces its lifespan. Blow this area with compressed air or carefully clean it with a dry brush. In models with an automatic self-cleaning station, you also need to check the corrugated hose and filter in the database for blockages.
What happens if you don't change the filter?
Caring for wheels and navigation sensors
The wheels of the robot vacuum cleaner are in constant contact with the floor, collecting dust, wool and hairs. Over time, tight windings form on the axis of the wheels that can block the wheel or cause the drive belt to slip inside the body. Lift the device and check each wheel: it should rotate freely and with a characteristic click when pressed. If the wheel is tight, it should be removed (if the design allows) or carefully cleaned with a brush and tweezers.
Special attention should be paid to sensors. In models with a laser rangefinder (LDS), you need to wipe dry soft cloth transparent window on the top cover and the laser unit itself underneath. Dust on the laser lens distorts the map of the room, the robot can "lose" or create artifacts on the map. Fall sensors (located at the bottom along the perimeter) and the collision sensor (bumper at the front) also require regular wipe.
- 👁️ Rub the laser rangefinder lens with a soft microfiber without pressing so as not to scratch the optics.
- 🧱 Clean the fall sensors of dust, otherwise the robot may consider the presence of a step where there is none, and stop.
- 🚗 Check the spring-loaded charging contact on the bumper - it should not stick in a depressed state.
Charging contacts on the bottom of the device and at the docking station are often oxidized or covered with a layer of dust, leading to poor contact and intermittent charging. Wipe them with a dry cloth or cotton swab lightly moistened with alcohol (only metal areas, avoiding plastic). Contact oxidation is a common reason why the robot can't charge to 100% or constantly interrupts charging.
Maintenance of the wet cleaning module (if any)
If you use a wet cleaning robot, proper water tank care is critical to preventing mold and bad smell. After each cleaning, be sure to drain the remaining water from the tank. Even if you use distilled water, the closed-loop moisture stagnation promotes bacterial reproduction.
Once a month, a preventive cleaning of the tank is recommended, pour warm water with a little citric acid or a special decalcination agent, leave it for 30 minutes, then rinse thoroughly, which will help remove scale that forms on the walls and can fill microholes in the pump or water supply valve.
A wet cleaning rag also requires attention. Wash it after 2-3 uses so that it does not become a source of dirt on the floor. If the rag has lost its absorbent properties or pile, replace it with a new one. Using too wet or, conversely, a dried cloth reduces the efficiency of cleaning and can leave divorces.
⚠️ Warning: Never leave water in the tank for storage unless the robot is used for several days.Stagnant water can lead to corrosion of the internal elements of the pump and the appearance of a persistent smell of dampness in the apartment.
Cleaning of turbines and vents
The turbine (an impeller motor) is the heart of the suction system. Over time, fine dust can penetrate the filters and settle on the blades of the impeller, creating imbalances and noise. You can get to the turbine by removing the bottom cover of the case (usually a cross screwdriver). If you hear an extraneous whistle or a hum, check the turbine camera.
Carefully remove dust lumps from the blades with a dry brush or cotton swab. Try not to make any effort to the shaft of the motor so as not to damage the bearings. Also check the vents on the robot body through which hot air escapes from the battery and motor.
💡
Regular cleaning of the vents and turbines prevents overheating of the electronics and prolongs the life of the battery by 20-30%.
When assembled after cleaning the turbine, make sure that all screws are tightly twisted but without stretching, and the rubber seals fall into place.Distressing the suction chamber will result in a loss of power, as air will be sucked through the cracks, bypassing the garbage collector.
Frequent cleaning errors and their consequences
One of the most common mistakes is to use aggressive chemicals or large amounts of water when cleaning plastic parts, especially those that come into contact with electronics. Aggressive solvents can corrode plastic, making it brittle, or flush factory lubrication from moving machinery. Water caught on the control board often causes corrosion, which does not appear immediately, but after a few weeks.
Another mistake is ignoring replacement consumables, and many users have been using the same thing for years. HEPA-The filter just shakes it out, and over time, the filter pores get clogged with fine dust that can't be cleaned out with a dry brush, and the robot keeps running, but the engine is struggling tremendously, and the air quality at the outlet is low.
⚠️ Warning: Don't lubricate the wheels and brush axles with oil or silicone lubricant just in case. The sticky lubricant base will attract dust and wool, creating an abrasive gruel that will accelerate the wear of parts.
Also, don't use a vacuum cleaner to clean the robot vacuum cleaner itself unless your vacuum cleaner has a power-adjusted blowout mode. The powerful airflow can drive dust deeper into electronic components or damage the thin membranes of microphones and sensors.
