Xiaomi Mi Robot Vacuum Mop has become an indispensable cleaning assistant for thousands of users, but its effectiveness depends on regular maintenance. Many owners face a problem: the device begins to collect less dust, makes extraneous sounds or refuses to work at all. 90% of the time lies in the contamination of key nodes, from the main brush to sensors. This article will help to understand how to completely clean the robot vacuum cleaner without damaging fragile components, and return it to factory performance.
Unlike conventional vacuum cleaners, Xiaomi Mi Robot Vacuum Mop requires a comprehensive approach: here it is important not only to remove visible dirt, but also to clean the hidden cavities where dust and hair accumulate. We will cover all the steps from basic cleaning after each cleaning to deep disassembly with filter washing and bearing lubrication, which the manufacturer recommends every 3-6 months, with a focus on typical errors that reduce the life of the device by 30-40%.
1.Preparation for cleaning: what will be needed and safety measures
Before you start dismantling, prepare the workspace and tools.
- 🧼 Soap or dishwashing agent (without abrasives)
- 🧻 Soft microfiber tissue (2-3 pieces)
- 🔧 Plastic blade or blunt knife to remove caps
- 🧷 Toothpicks or cotton swabs for cleaning bottlenecks
- 💧 Distilled water (for filter washing)
- 🔋 Screwdriver cross (for some models)
Important: Xiaomi Mi Robot Vacuum Mop has sealed compartments with electronics. Under no circumstances do not immerse the body in water or use aggressive detergents. To clean electronic components (sensors, contacts) only dry microfibre or compressed air. If the vacuum cleaner has been in operation for more than a year, check the condition of the rubber seals - they may lose elasticity and require replacement.
⚠️ Warning: Before cleaning, be sure to remove the battery (if possible in your model), or at least disconnect the device from the charging station. Contacts on the bottom of the robot can be closed if moisture is ingested, which will cause the control board to fail.
2. Daily cleaning: what to do after each cleaning
Even if your Mi Robot Vacuum Mop looks clean, you need to perform minimal maintenance after each cleaning cycle, which will take no more than 5 minutes, but will extend the life of the device by 20-30%.
Mandatory action:
- Empty the dust collector -- press the latch on the back cover and shake the trash out of the urn. Don't knock on the tank so you don't damage the filter.
- Check the main brush for hair and threads that have wound, remove them with your hands or tweezers.
- Wipe the side brush with a wet wipe - it is most often clogged with dust.
- Inspect the mope module (if any): rinse the fabric nozzle under running water and squeeze.
Pay special attention to the impact sensor (located around the perimeter of the body), which is often covered with a thin layer of dust, which leads to false positives. Wipe it with a dry wipe. If the robot begins to "see" obstacles where there are none, this is a sure sign of sensor contamination.

3. Deep cleaning: disassembly and washing of key nodes
Every 1-2 months (or after 20-30 cleaning cycles), the Xiaomi Mi Robot Vacuum Mop requires a complete disassembly, which takes 30-40 minutes, but will remove accumulated dirt in hard-to-reach places.
Step-by-step:
- Removal of the upper cover: Turn the robot over and unscrew 4 screws (in some models, the cover is kept on the latches - put it with a plastic spatula).
- HEPA- filter extraction: It is located next to the motor. Carefully pull the tongue. If the filter is deformed or torn, a replacement is required.
- Turbine cleaning: Remove the protective grille of the fan (a screwdriver may be required). Remove the wound hair from the motor shaft with a toothpick.
- Wash the dust collector: Disassemble the tank into 2 parts (usually a case and a removable cover). Rinse with warm water and soap, then dry for 24 hours.
To clean the optical sensor (under the transparent lid at the front), use a cotton swab dipped in alcohol. Don't press hard, it's a fragile element. If the robot is still poorly oriented after cleaning, check the laser rangefinder (in LDS models) - its lens should be perfectly clean.
| Node. | Frequency of cleaning | Signs of pollution | Consequences of neglect |
|---|---|---|---|
| HEPA-filter | Every 1-2 months | Reduced suction, smell of dust | Overheating of the engine, failure |
| Main brush. | After every cleaning. | Wrapped hair, creaking | Bearing breakage, jamming |
| Sidebrush | Once a week. | Slow-motion rotation | Insufficient cleaning at the edges |
| Sensors. | Once a month | False positives | Incorrect navigation |
| Turbine | Every 3 months | Extraneous noise | Engine overload |
💡
If after washing the filter, it has lost its shape, put it overnight under a press (for example, a heavy book) – this will help restore the structure.
4.Brushing: hair removal and bearing lubrication
The brushes are the most vulnerable element in the Xiaomi Mi Robot Vacuum Mop. Hair and threads are wound onto the shaft, blocking rotation and putting additional stress on the engine, in advanced cases, this leads to winding burnout or gear failure.
How to Clean the Main Brush:
- Press the locks on the sides of the brush and remove it from the body.
- Remove visible hair with your hands, then rinse the brush under running water.
- To remove dirt from bearings, use WD-40 or silicone lubricant. Apply 1-2 drops on the axle and scroll through the brush.
- Check the rubber nozzles at the ends of the brush – if they are worn, replacement is required.
The side brush is easier to clean: remove it by pulling it down, then rinse it underwater. Pay attention to the drive gear — if it's covered in dust, wipe it with a cotton swab. In models with a mop module, additionally check the water pump (located next to the water tank). Its membrane can be clogged with lime plaque — for cleaning use a solution of citric acid.
⚠️ Warning: Never use vegetable oil or petroleum petroleum to lubricate bearings. These substances attract dust and thicken over time, leading to jamming of the machinery. Only specialized silicone lubricants!
Cleaning of sensors and electronic components
If your Mi Robot Vacuum Mop is starting to behave in an unpredictable way -- beating up furniture, skipping lots, or getting lost in space -- the problem is that the sensors are contaminated, and there are several types of sensors in the device, and each one requires a different approach.
Types of sensors and methods of cleaning them:
- 🔴 Infrared sensors (located around the perimeter of the body) - wipe them with a dry microfiber. Don't use alcohol!
- 🟢 Optical sensor (under a transparent cover) - Clean the lens with a cotton swab soaked in isopropyl alcohol.
- 🔵 Laser rangefinder (LDS) - remove the top cover and gently blow with compressed air. Don't touch the rotating mirror!
- ⚫ Fall sensor (bottom of the case) - wipe it with a napkin soaked in soapy solution, then dry.
Pay special attention to the contacts of the charging station (both on the robot and at the docking station). Oxidation or contamination of the contacts leads to poor battery charge. Use an eraser to clean, which effectively removes oxides without damaging the coating. After cleaning, wipe the contacts with alcohol.
What if the robot doesn’t return to base?
Caring for the battery and contacts
The battery is the most expensive part of the Xiaomi Mi Robot Vacuum Mop, and its improper operation reduces the lifespan from 3-5 years to 1-2.
What can and cannot be done:
- ✅ Store the robot at a charging station (optimal charge level is 40-80%).
- ❌ Leave discharged for a long time (deep discharge kills Li-ion batteries).
- ✅ Clean contacts every 3 months (see previous section).
- ❌ Use non-original chargers (they may not match the charge current).
If the robot is rapidly discharged, check the battery life in the Mi Home app. The normal value for a new battery is 90-120 minutes. If the time has dropped to 40-60 minutes, the battery requires replacement. To calibrate the battery completely discharge the robot (before turning off), then charge to 100% without interruptions.
Important: Some Xiaomi Mi Robot Vacuum Mop models have a non-removable battery, which requires replacing the case and soldering off the old battery. If you're not sure about your skills, you should contact a service center - soldering errors can lead to fire.
💡
Regular cleaning of the charging station and robot contacts increases the battery life by 20-30%.
7 Frequent cleaning errors and how to avoid them
Many users make mistakes that lead to the breakdown of Xiaomi Mi Robot Vacuum Mop.
Top.-5 errors and their consequences:
- Using a vacuum cleaner to clean the filter → Destroys the fibers of the HEPA- filter, reducing its efficiency.
- Drying the filter with a hairdryer → Deforms the material, leads to cracks.
- Clean sensors with a wet napkin → Short circuit on the sensor board.
- Ignoring the creak of the brushes → Breakage of the gearbox and replacing the brush assembled.
- Storage of the robot in a wet room → Corrosion of contacts and boards.
Another common problem is that you don't build properly after cleaning, for example, if you don't fix the dust collector tightly, the robot will lose suction power.
- 🔹 The dust collector cap is snapped.
- 🔹 The filter is mounted on the correct side (it has a label "UP").
- 🔹 The brushes rotate freely, without backlash.
If the robot gets worse after cleaning, check the suction settings in the Mi Home app. Sometimes calibrations get lost after disassembly, and the power has to be adjusted again.
8.Prevention: How to prolong the life of a robot vacuum cleaner
Regular cleaning is only part of the care.To make Xiaomi Mi Robot Vacuum Mop last longer, follow these guidelines:
Operational tips:
- 📅 Plan cleaning for a time when no one is home, which will reduce the risk of collisions with furniture.
- 🧹 Remove small objects (socks, wires, toys) from the floor, which can be wrapped on brushes.
- 🔋 Do not interrupt the charging cycle - wait for full charge (100%).
- 🌡️ Avoid cleaning in rooms with temperatures above 30°C — overheating reduces battery life.
- 📱 Regularly update your firmware through the Mi Home app – new versions optimize your cleaning algorithms.
For models with wet cleaning function (Mop), it is important to use only special wipes. Conventional rags leave a pile that clogs the pump. Also watch for the hardness of the water - if the water in your region is hard, add antinakipin (1 teaspoon per 1 liter).
If you use a robot to clean animal hair, clean it every day. Cats and dogs quickly accumulate in the filter and brushes, creating the perfect environment for bacteria. You can use a UV lamp to disinfect (after cleaning, direct light to the filter and dust collector for 10-15 minutes).
💡
The use of original consumables (filters, brushes, wipes) increases the life of the robot by 40% compared to non-original spare parts.
