How to Clean the Xiaomi Vacuum Cleaner Robot Cleaner 1S: step-by-step instructions with photos and tips

Xiaomi Vacuum Cleaner Robot 1S It has become an indispensable cleaning aid for thousands of users, but its effectiveness depends on regular maintenance, and many owners face the problem of reducing suction power, navigation errors, or unpleasant odor after a few months of use. The reason most often lies not in the breakdown, but in the contamination of key nodes that require systematic cleaning.

In this article, we will discuss all the steps of cleaning - from the basic processing of the garbage container to deep cleaning of sensors and brushes, which the manufacturer recommends to carry out at least 1 time every 2 weeks. HEPA-What to do if the robot starts to "glut" after cleaning, and we will focus on hidden areas of dust accumulation, which are not mentioned in the official instructions, but which directly affect the life of the device.

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

Before you start the dismantling of Xiaomi 1S, Get the workspace and the tools ready:

• 🧴 Soft brush (dental or dust brush) - for cleaning cracks and sensors.
• 🧼 Wet wipes without alcohol (or microfibre) - for cleaning the case and sensors.
• 🔧 Flat screwdriver or plastic mediator - for careful removal of covers.
• 🧲 Vacuum cleaner with a narrow nozzle - to remove dust from hard-to-reach places.
• 💧 Warm water (not hot!) – for washing containers and filters.

Important: Xiaomi Vacuum Cleaner 1S It has some fragile elements that are easily damaged by careless cleaning, such as side brushes attached to plastic axles, and drop sensors (cliff sensors) are covered with a thin film. Never use abrasive materials (sandpaper, hard sponges) or aggressive detergents (acetone, gasoline).

⚠️ Warning: Before cleaning, be sure to remove the battery (if you plan to wash the container underwater) or at least disconnect the robot from the charging station. 1S removable battery - to extract it, you will need to unscrew 4 screws on the bottom cover.

Cleaning of the garbage container and the main filter

A garbage container is the "heart" of a vacuum cleaner that accumulates up to 90% of all dirt. 1S It consists of two parts: the main compartment (where the garbage gets into). HEPA-If the container is not cleaned in time, the dust begins to penetrate back into the air, and the filter loses its throughput.

Step-by-step:

1. Press the Release button on the back of the robot and remove the container.
2. Holding the container over the trash can, tap the orange latch at the bottom to open the lid.
3. Remove the large debris manually, then shake out the fine dust. Use a narrow-fixed vacuum cleaner for thorough cleaning.
4. Wash the container with warm water (not higher than 40).°C) with a soft detergent. Do not use hard bristles, they scratch the plastic.
5. Extract. HEPA-filter (gray rectangle inside the container) and vacuum or rinse it under a weak stream of water!

Tip: If the robot makes a whistling sound after cleaning, it's likely that the filter is installed incorrectly or that it hasn't completely dried out. 1S HEPA-filter has the direction of installation (indicated by the arrow on the body) - ignoring this will lead to a decrease in suction power by 30-40%.

3. Cleaning of side and main brushes

Brushes are the fastest wearable robot element. 1S There are three of them: one main (a roller with bristles and rubber blades) and two side ones (a rotating whisker), and if they are not cleaned, the hair, thread and fur of the animals are wound on the axle, blocking rotation, which leads to an error Error 10 ("jamming the brush") and premature wear of the engine.

How to Clean the Main Brush:

• 🔄 Unscrew the two screws on the bottom cover of the robot (use Phillips screwdriver #1).
• 🧹 Remove the brush by pressing the red fixtures on the sides.
• ✂️ With scissors or a knife, carefully cut the wound hair and threads. Do not pull them with your hands - this can damage the bristles.
• 💦 Wipe the axis of the brush with a wet wipe. If it's too polluted, rinse underwater and dry it.

The side brushes are easier to clean:

• 🔧 Press the black lock on the side of the brush and pull it on yourself.
• 🧼 Wash under water by removing dirt from under plastic blades.
• ⚠️ Check the plastic pin for wear and tear. If it cracks, the brush needs to be replaced.

💡

If the brushes are worn out, do not expect breakage – order original spare parts for Xiaomi 1S (articular ZNMS02WM for the main brush and ZNMS03WM for side) on AliExpress or in official Xiaomi stores. ~500-800 rubles.

⚠️ Attention: Once you have the brushes installed, check their rotation manually, and if the brush is clinging to the body or is rotating with difficulty, it is crooked or the hair is wound on the axis. 1S This causes an Error 12 error ("overloading of the brush motor»).

Cleaning sensors and sensors: why the robot is “blind”

If you want to use Xiaomi Vacuum Cleaner 1S He started to flock to furniture, "not see" the charging station or randomly move around the room, the problem is that the sensors are contaminated:

Pay special attention to laser lidar – this is the most vulnerable place in Xiaomi 1S. Dust on the lidar glass leads to distortion of the room map and Error 2 error ("navigation problem:

1. Turn off the robot.
2. Carefully scroll the lidar “tower” with your hand to open the glass.
3. Wash it with a dry lilaless napkin (do not use wet wipes!).
4. Blow the gap around the lidar with compressed air (for example, a canister to clean the keyboard).

5. Deep cleaning: fan, motors and hidden cavities

If the robot is still poorly sucking or humming louder than usual after surface cleaning, the problem lies in the fan or motors. 1S access to them is difficult, but with accuracy you can cope without disassembly.

Fan cleaning:

• 🔧 Remove the bottom cover (4 screws).
• 🌀 Under the cover you will see a black plastic fan casing.
• 🧹 With a narrow nozzle, remove dust from the holes of the casing (do not disassemble it!).
• 🔄 Manually scroll the fan - it should rotate without jamming.

If the fan is jammed, it's likely to have been hit by a large piece of debris (hair, thread).

1. Disconnect the fan power connector (take care of the plastic fixture).
2. Unscrew 2 screws holding the casing.
3. Remove the trash with tweezers or a toothpick.
4. Collect in reverse order, making sure that the fan blades do not touch the body.

⚠️ Warning: When cleaning the fan, do not touch the motor contacts - static electricity can damage the control board. If after assembly, the robot emits an Error 5 error ("fan problem"), check that the connectors are connected correctly.

💡

Regular fan cleaning extends the life of the engine by 30-50%.In service centers, replacing the fan motor for Xiaomi 1S It costs 2–3 thousand rubles, while self-prevention takes 10–15 minutes.

Smell removal and disinfection

Over time, the robot vacuum cleaner has a bad smell, which is especially noticeable when turned on.

• 🦠 Bacteria in a dumpster (especially if you remove wet garbage).
• 🐾 Animal hair stuck in brushes.
• 🌿 Mold on HEPA-filter (if it is not properly dried).

How to eliminate the smell:

1. Wash the container with an antibacterial agent (for example, Miramstin or Chlorhexidine, diluted with 1: 1 water).
2. Dry the filter in the sun for 6-8 hours (UV light kills bacteria).
3. Treat your brushes with a disinfectant spray (such as Lysol).
4. Put in the container a bag with silica gel (absorbs moisture) or activated carbon (elimines odors).

If the smell is still there, check the rubber seals on the container - over time they absorb the smells. They can be washed in soapy solution or replaced (article). ZNMS05WM).

7. Frequent mistakes and how to avoid them

Many users of Xiaomi 1S They're going to have a problem after cleaning, and here's how to prevent it:

• 💧 Make sure there is no moisture left anywhere (especially on the control board).
• 🔌 Connect the robot to charge for 10-15 minutes – sometimes a discharged battery blocks the switch on.

Mistake 2: Suction power decreased

• 🌀 Check if the duct is clogged (the tube from the container to the fan).
• 🔍 Make sure that HEPA-filter is installed on the correct side (the shooter must look upwards).
• 🛠️ If the filter is torn or deformed, replace it (original article) ZNMS04WM).

Mistake 3: Robot 'can't see' charging station
