Robot vacuum cleaner Xiaomi Mi Robot Vacuum (or newer models of the series Xiaomi Robot Vacuum-Mop) has become an indispensable tool in cleaning for thousands of users. But even the most advanced technique requires regular maintenance – clogged filters, worn-out side brushes or contaminated sensors can lead to a drop in suction power, navigation errors and even breakdowns. In this article, we will analyze how to clean the Xiaomi vacuum cleaner yourself, without contacting the service center, and extend its service life by 30-50%.

Many owners make a critical mistake: they limit themselves to emptying the garbage container, forgetting about the main filter. HEPA, Meanwhile, according to service centers, 68% of Xiaomi robot vacuum cleaner breakdowns are due to late cleaning of internal components. 1S Xiaomi Robot Vacuum-Mop 2 Ultra, including nuances for devices with wet cleaning function.

Cleaning won't take much longer. 20-30 It takes a minute, but it's going to take care, especially when you're working with electronic sensors and movable machinery. If you've never taken a vacuum cleaner apart, start by getting the tools ready and learning the diagram of your model (you can find it in the Mi Home app in the Device section). → User manual).

1.Preparation for cleaning: what will be needed and safety measures

Before disassembling, make sure the vacuum cleaner is completely off and disconnected from the charging station. Do not clean the device under running water - most components (except the garbage container) are not designed to come into direct contact with the liquid.

• 🧴 Soft brush (a tooth or brush for makeup is suitable) - for cleaning filters and hard-to-reach places.
• 🧽 Microfibre wipe - for cleaning the case and sensors.
• 🔧 Flat screwdriver (for models with screw brush attachment).
• 💧 Alcohol wipes or isopropyl alcohol (70%+) — sensor-degreasing.
• 🧼 Warm water with soap (non-aggressive detergents!).

If your model supports wet cleaning (e.g. Xiaomi Robot Vacuum-Mop P), prepare an additional clean water tank to flush the spray system.Never use abrasive sponges or metal objects - they will damage the anti-reflective coating of the sensors and plastic parts.

⚠️ Note: Some models (e.g. Xiaomi Mi Robot Vacuum) 2) They have a lithium battery that you can't overheat. If you clean the vacuum cleaner after a long time, let it cool down. 15-20 minute.

2. Cleaning of the garbage container and the main filter

The garbage container is the first item that needs attention after every cleaning, but what few people know is that the main filter is hidden inside it. HEPA, It's clogged with the smallest dust and hair, and here's how to clean it:

1. Click on the opening button of the container lid (usually located on the top panel of the vacuum cleaner).
2. Remove the container and empty it over the trash can. Don't knock on it, it could damage the sealing gums.
3. Disconnect the filter HEPA (It's mounted on latches or threads. In Xiaomi Robot Vacuum-Mop 2 Ultra, the filter can be hidden under a removable lid.
4. Wash the filter under warm (not hot!) water with mild soap. Use a brush to remove persistent contaminants.
5. Dry the filter thoroughly for at least 12 hours before re-installing it, and installing a wet filter will cause mold growth and unpleasant smell.

If the filter is damaged (torn, deformed) or not cleaned even after washing, it must be replaced.

In models with wet cleaning function (Xiaomi Robot Vacuum-Mop), additionally check the water tank for plaque. 1-2 weekly (1:10 water, but do not forget to rinse thoroughly!

3. Turbine and side brush cleaning: remove hair and thread

The brushes are the most vulnerable part of the robot vacuum cleaner. The turbine brush (main) and the side brushes are in constant contact with debris, hair and threads that wind on the axle and block rotation. If the vacuum cleaner starts sweeping worse or makes grinding, first check the brushes.

To clean the turbine brush:

1. Turn the vacuum cleaner over and find the brush mount (usually fixed with latches or a single screw).
2. Take off your brush and remove the wound hair with a knife or tweezers. Be careful not to damage the bristles!
3. Wash the brush underwater if it's heavily polluted. Dry away from direct sunlight.
4. Check the bearings for backlash. If the brush is hanging, it's time to replace it.

The side brushes are easier to clean:

• 🔄 Remove the brush by pulling it to the side (in most models, mounting on latches).
• 🧹 Remove hair and debris from the axle. Use a toothpick for hard-to-reach places.
• 🔍 If the bristles have decreased by more than 30 percent, the brush should be replaced.

Xiaomi Robot Vacuum-Mop 2 The Ultra turbine brush can be equipped with a self-cleaning mechanism, but this does not eliminate the need for manual cleaning once in a while. 1-2 If the brush doesn't rotate even after cleaning, check the drive belt, it could have jumped or broken.

⚠️ Warning: Do not lubricate the brush axles with oils or silicone sprays! This will cause dust to stick and wear the bearings faster. For lubrication (if required), use only special robotics formulations.

💡

If the hair is badly wound on the axis of the turbine brush, try to remove them with a stationery knife, pre-moistened the knot with alcohol - this will facilitate the process.

Cleaning sensors and sensors: why the vacuum cleaner is “blind”

Sensors are responsible for navigation, obstacle detection and altitude control, and if the vacuum cleaner is moving into furniture, skipping sections, or moving randomly, the problem is the contaminated sensors, and Xiaomi models are the most vulnerable.

• 👁️ Lidars and cameras (in models with LDS or ToF sensors).
• 📏 Collision sensors (bumper with micro-switches).
• 📉 Height sensors (prevent falling from stairs).
• 🔋 Contacts of the charging station.

For cleaning:

1. Wipe the lidar (the rotating "turret" on the top panel) with a dry microfiber wipe. In camera models (Xiaomi Robot Vacuum-Mop 2 Pro), additionally wipe the lens.
2. Clean the bumper of dust and check the progress of the micro-switches (they should be easily pressed).
3. Wipe the height sensors (located on the bottom panel) with an alcohol napkin.
4. Clean the contacts of the charging station and vacuum cleaner from oxidation (use an eraser or alcohol).

If after cleaning the vacuum cleaner still does not see an obstacle, check the settings in the Mi Home application:

The device → Settings → Navigation → Sensor sensitivity

For models with LDS (laser sensors can be calibrated:

Device → Settings → Additional → Calibration of LDS

5. Battery care: how to extend the operating time

Lithium-ion batteries in vacuum cleaners Xiaomi designed for 300-500 They're charging cycles, but if they're not used properly, they drop in capacity after a year, to extend the battery life:

• 🔌 Do not keep the vacuum cleaner on charge all the time. Optimal mode: charge to 80-90% discharge 20-30%.
• 🌡️ Avoid overheating (do not put the vacuum cleaner under direct sunlight or near heating batteries).
• 🔄 Once every 3 months, complete a full discharge-charging cycle (discharge to 0%, then charge to 100%).
• ⚡ If the vacuum cleaner is not used for more than a month, store it with a charge. 40-50%.

If the work time has been reduced to 20-30 minutes (at initial) 90-120), The battery needs to be replaced. Original batteries for popular models:

Replacing the battery can be done on your own, but care is required when disconnecting the old battery (risk of damage to the plumes).

💡

Regular cleaning of battery contacts (once in a week) 6 months) prevents oxidation and improves charging on 15-20%.

Prevention and frequency of cleaning: maintenance schedule

To make Xiaomi vacuum cleaner work like new, stick to the following maintenance schedule:

For models with wet cleaning function (Xiaomi Robot Vacuum-Mop) additionally:

• 💦 Wash the water tank and tubes after each use.
• 🧽 Change the water in the self-cleaning database (if any) once in a while. 3-5 days.
• 🧴 Use only original detergents – third-party cleaners can damage the pump.

If you live in a house with animals or often remove long hair, increase the frequency of brushing and filters in your home. 1.5-2 For automatic service reminder, set up notifications in the Mi Home app:
