Keeping the house clean is a smart assistant’s job, but who will take care of the device itself? Regularly preventing the internal mechanisms of Xiaomi’s robotic cleaner is essential to keep it suction-intensive and prevent breakdowns. Ignoring simple hygiene rules can cause the motor to overheat or cause the battery to fail quickly.
In this article, we will take a look at the maintenance of the popular Mi Robot Vacuum and Roborock series, learn how to properly remove and wash filters, clean the main brush of wound hair and handle sensors, and help you avoid the typical mistakes that beginners often make when first servicing equipment.
Timely cleaning is not just an aesthetic, but a technical necessity for the stable operation of the navigation system.
Owners often underestimate the importance of removing fine dust from side compartments, which eventually leads to wheels jamming.
We will disassemble each node separately so that you can conduct the full TO of your gadget in 15-20 minutes.
Preparation for maintenance and security measures
Before any manipulations start, you must completely stop the current cleaning and send the device to the base.
It is important to disconnect the robot vacuum cleaner from the network if it is in a docking station to eliminate the risk of short circuits when wet parts come into contact with electronics. Safety is the number one priority when working with electrical appliances.
⚠️ Warning: Never immerse the main body of the robot, containing electronics and battery, in water or under a stream of water from the tap.
To work, you'll need a dry soft cloth, perhaps a small brush to clean (often included) and a water tank to flush consumables. Make sure you have free space on the table or floor to disassemble components.
☑️ Ready to clean
Some models have a removable container, others are integrated into the case, so the approach may vary slightly depending on the specific modification of the Xiaomi Vacuum.
Dismantling and cleaning of the dust collector
The first step is always to remove the dust container, which is usually fixed by latches and removed by moving up or sideways, depending on the design of the model.
Empty the container over the trash can. Tap lightly on the walls to remove fine dust that may have settled in the corners. Filtration hygiene starts at this point.
- 🗑️ Shake off the bulk of the trash with light taps.
- 💨 Blow the inner walls with a dry jet of air or use a soft brush.
- 🚿 Wash the plastic tank with water if the instructions for your model allow it.
- 🌬️ Leave the container dry for at least 24 hours before installing it back.
If your model uses cyclone dust system, look for the rough cleaning mesh filters inside the bunker, which also need to be gently knocked out or washed.
Can I wash the container with soap?
Service HEPA-filter and motor protection
The most critical element of the filtering system is HEPA-It's the filter that traps the smallest particles of dust, allergens and bacteria, preventing them from returning to the air of the apartment.
In most Xiaomi Robot Vacuum models, the filter is located at the top of the container or in a separate compartment above the engine, and must be removed before each wet cleaning or at least once a week during active use.
| Type of filter | Cleaning method | Frequency | Time of replacement |
|---|---|---|---|
| Prefilter grid | Water washing | Once a week. | 6–12 months |
| HEPA E11/E12 | Dry brushing | Once every 2 weeks | 2-3 months |
| Protective sponge | Replacement | As we wear it out | 1 month |
It is strictly forbidden to wash HEPA-water filter, unless the package or body has a special "Washable" badge, soaked paper or synthetic filter loses its properties, deforms and can cause engine turbine failure due to increased air resistance.
Carefully tap the filter on the edge of the sink to knock out deep dust. Use a dry toothbrush to clean the folds of the material. If the filter is blackened or damaged, it should be replaced with an original or compatible counterpart.
💡
Wet HEPA-filter is the main cause of the drop in suction power and overheating of the engine.
Cleaning the main turbo brush
The central brush is the working organ that sweeps out the debris from the carpet villi, and over time, it accumulates hair, animal hair and thread, which puts additional stress on the engine.
Turn the robot vacuum cleaner upside down. Open the main brush compartment cover, which is usually held on two latches. Remove the brush shaft by pulling one of the ends.
- ✂️ Cut the tightly wound hair in the center of the shaft with scissors (be careful not to damage the bristles).
- 🧶 Remove the coiled tangles of wool from both ends of the brush.
- 🧼 Wash the shaft itself under running water if it is heavily contaminated with sticky dirt.
- 🔍 Check the bearings on the ends of the shaft for foreign objects.
Pay special attention to the ends of the brush where the bearings are located. Often that's where small debris gets stuck, which causes creaking or difficulty rotating. Bearings should rotate freely and silently.
After washing, be sure to wait for the shaft to dry completely before installing. Moisture inside the mechanism can lead to oxidation of contacts or mold.
Care for side brushes and wheels
The side blades are responsible for sweeping debris out of corners and along the boards to the central air intake hole, and they experience constant friction against the floor.
To remove the side brush, it is usually enough to simply pull it upwards. Clean the pile of dust and hair. If the brush is worn out, the villi become short or have lost shape, it is better to replace it, since the efficiency of cleaning the corners decreases dramatically.
⚠️ Attention: When you put the side brush back in, make sure it's in the grooves before the characteristic click. A loosely secured brush can fly off while working and get stuck under the robot.
Don't forget to look at the main wheels. Lift the robot above the floor and spin it with your hand. If you notice the hair wound on the wheel axis, carefully remove it with tweezers or a knife. Clogged wheels are a common cause of navigation errors and device jams.
Wipe the wheels and sensors underneath with dry cloth. Dirt on the height sensors (fall sensors) can cause the robot to falsely detect obstacles or, conversely, fall down stairs.
Processing of sensors and charging contacts
And on the bottom panel and around the bumper, there are different sensors -- collision sensors, floor sensors, infrared receivers to communicate with the base -- and the contamination of these elements leads to chaotic behavior.
Wipe all black sensor windows with a soft dry wipe.Do not use aggressive chemicals or alcohol that can leave stains or damage plastic.
Special attention is required metal contacts on the bottom of the robot and on the charging base, oxidation or dust plaque on them lead to poor charge.
Recommended: Dry microfiber or cotton swab, slightly moistened with alcohol (only for metal contacts!).Make sure that the base is also free of dust in the area of the contact areas.
💡
Clean the sensors and contacts every time you clean the wet, when the robot has been driving through wet areas of the floor, and this will prevent lime plaque from forming.
