Cleaning the nozzle of the robot vacuum cleaner Xiaomi: restore the power of suction

Xiaomi’s robot vacuum cleaners are real cleaning assistants, but over time, even they get worse at the task, and one of the main reasons for the decline in efficiency is clogging of nozzles (air channels through which air flows). Dust, hair and small debris accumulate in narrow ducts, reducing the suction power by 30-50% after 6-12 months of active use. V3 it became worse to collect garbage, emits an uncharacteristic whistle or overheats - the problem is most likely in the nozzles.

In this article, you will find step-by-step instructions for cleaning nozzles without disassembling the body, and how to prevent their rapid contamination. We will examine the design features of different Xiaomi models, the appropriate tools and common errors that lead to a vacuum cleaner breakdown. No complex manipulations, only proven methods that will return your robot to its old appetite for dust.

Why do the nozzles get clogged and how it manifests itself

The nozzles (or air channels) in Xiaomi robot vacuum cleaners are narrow plastic or rubber tubes that move air through, creating suction. Their diameter rarely exceeds 5-8 mm, so even a small amount of dirt can seriously disrupt work.

• 🧹 Long hair and animal hair – wrapped around the turbine and pushed by the flow of air into the channels, forming dense “congestion).
• 🏚️ Construction dust and sand — small abrasive particles settle on the walls of the nozzles, narrowing the clearance.
• 🧼 Residues of detergents – if you use the wet cleaning function, soap plaque can crystallize inside the channels, forming sticky deposits.
• 🌿 Plant debris – leaves, needles or flower pollen when ingested into the suction tract swell from moisture and block the flow.

How do you know if the nozzles are clogged? Notice the following symptoms:

⚠️ Note: If the Xiaomi robot vacuum cleaner starts to shut down automatically after 5-10 minutes of operation, this may indicate a critical clogging of the nozzles, leading to overheating of the turbine.

What tools will be needed to clean

No professional tools are needed to clean the nozzles, just what you'll find in every home, but some tools will make it a lot easier.

• 🔧 Flat and cross screwdrivers (for models with a collapsible body, for example, Dreame Bot) Z10 Pro).
• 🧷 Tweezers with long sponges – will help to extract hair from deep canals.
• 🧼 Toothbrush with hard bristles or bottle brush - ideal for cleaning curved nozzles.
• 💨 A compressed air balloon (for example, to clean keyboards) – blows dust from hard-to-reach places.
• 🧴 Alcohol wipes or cotton swabs - to remove sticky deposits.
• 🔦 Lantern - illuminates the internal cavities during visual inspection.

For deep cleaning (if the nozzles have not been cleaned for more than a year), you can use:

• 🧪 Ultrasonic bath - for soaking removable plastic parts (only if they are not electronic!).
• 🧴 Special cleaners for vacuum cleaners (e.g, Kärcher or Thomas - dissolve fat deposits.
• 🔧 A set of plastic blades - for careful tweaking of covers without scratches.

⚠️ Warning: Never use metal objects (needles, knives, wire) to clean your nozzles! Risk of damaging plastic ducts or tearing rubber seals is extremely high. If the cork doesn't lend itself, it's best to disassemble the case according to the instructions for your model.

Step-by-step instructions: how to clean the nozzles without disassembling the body

If the clogging is not critical, you can do without completely disassembling the vacuum cleaner. This method is suitable for most models of Xiaomi Mi Robot, Dreame Bot and Viomi with a classic layout.

1. Turn off the vacuum cleaner and remove the battery (if possible indiscriminately) to prevent the turbine from accidentally turning on.
2. Take the dust collector and the filters off. Most models just press the latch or turn counterclockwise. Notice the sealing ring, and you have to clean it out of the dust.
3. Look at the visible nozzles. They're usually located: 🔍 Behind the dust collector (main air channel). 🔍 Under side brushes (channels for sucking garbage from the edges). 🔍 In the turbine area (if a plastic pipe is visible).

Remove visible debris

• 🧹 Hair and threads gently pick up with tweezers.
• 🧽 Wash the dust and sand with a pear soaked in a soapy solution.
• 💨 Blow the channels with compressed air (hold the balloon vertically so as not to freeze the plastic!).
• Check the side brushes. Their axes often become the hair collectors, which then enter the nozzles. Take off the brushes and clean the grooves.

Once you clean, collect the vacuum cleaner and run the test: turn on maximum power mode. If the whistle is gone and the suction is smooth, the task is completed successfully. If problems persist, you will need a deep cleaning and parsing.

💡

For models with a laser rangefinder (for example, Mi Robot Vacuum-Mop P) before cleaning, cover the lidar with a napkin - dust that gets on the lens can distort the map of the room.

Deep cleaning: disassembly of the body and access to hidden nozzles

If surface cleaning doesn't work, you'll have to disassemble the vacuum cleaner. This method requires precision, but allows you to get to deep blockages in the air channels. The instructions are universal for most Xiaomi models, but note that some parts (such as the location of the screws) may differ.

Step 1: Dismantling the upper cover

1. Turn over the vacuum cleaner and remove the side brushes.

2 Unscrew the screws on the bottom panel (usually 4-6 pieces, hidden under stickers or rubber legs). In Dreame Bot models, there may be additional latches - put the lid with a plastic blade.

3. Carefully remove the upper part of the body, do not pull the wires!

Step 2: Access to turbine and nozzles

1. disconnect the turbine power connectors (remember their location or take a picture).

2. Unscrew the turbine mounts and remove it, and underneath that, you'll see the main air channel, and you'll need to clean it first.

3. Blow the channel with compressed air and wipe the walls with a napkin soaked in alcohol.

Step 3: Cleaning the side nozzles

Side channels are often clogged by debris from the edges, to clean them up.

1. Remove the plastic guide brushes - under them are hidden the entrances to the nozzles.

2. Blow the channels with a brush or compressed air. If the cork is dense, use tweezers.

3. Check the airflow sensor (if any) – it may be covered in dust, causing the robot to show false errors.

Step 4: Assembly and testing

1.Make sure all nozzles are clean and dry.

2. Collect the vacuum cleaner in reverse order, checking the density of the seals.

3. Turn on the vacuum cleaner and test on different surfaces.

• 🔊 Absence of extraneous sounds (whistling, creaking).
• 💨 Uniformity of suction (can be checked with a sheet of paper).
• ⚡ Battery life (must return to original).

⚠️ Note: In models with automatic vacuuming (for example, Xiaomi Mi Robot Vacuum-Mop 2 Ultra) there is an additional pneumatic channel connecting the vacuum cleaner to the docking station. It also needs to be cleaned every 3-4 months, otherwise the robot will not be able to dump garbage into the container.

Features of cleaning nozzles in popular Xiaomi models

The design of the nozzles may vary depending on the model, and consider the nuances for the most common robot vacuum cleaners Xiaomi:

For models with laser navigator (LDS) Be careful when disassembling the head, so don't touch it or send compressed air to it. Dust on the lidar lens causes the map to be incorrectly constructed.

Self-emptying robots (e.g. Xiaomi Mi Robot Vacuum-Mop 2 Ultra) have an additional pneumatic hose connecting the vacuum cleaner to the docking station, which must be cleaned every 3 months, otherwise the debris will get stuck halfway.

💡

If your model is equipped HEPA-It also needs to be cleaned or replaced every 6 months, and a clogged filter creates additional resistance to air, accelerating the clogging of the nozzles.

What not to clean the nozzles: common mistakes

Not only can the cleaning fail, but it can also disable the vacuum cleaner.

• 🚫 Use sharp metal objects (knives, needles, screwdrivers) - they scratch the plastic and tear rubber seals, which leads to loss of tightness.
• 🚫 Wash the nozzles under running water - moisture can get into the turbine or on the control board, causing a short circuit. L10).
• 🚫 Use harsh chemicals (acetone, gasoline, solvents) - they corrode plastic and rubber. Only alcohol solutions or specialized cleaners are allowed.
• 🚫 Dry the nozzles with a hair dryer or on a battery - high temperatures deform the plastic.
• 🚫 Ignore errors after assembly – if the vacuum cleaner beeps or flashes red, then you forgot to connect the sensor or installed the turbine incorrectly.

Another common mistake is to clean only visible areas, and many users limit themselves to removing debris from the dust collector and filter, unaware that the main blockages are hidden deeper, such as the Mi Robot Vacuum, which has an additional channel behind the turbine, which clogs up 80 percent of long-term use.

Also not worth it:

• 🔌 Turning on the vacuum cleaner with the removed turbine - this can burn the control board.
• 🧲 Use magnets to extract metal particles – they can damage Hall sensors in motors.
• 🔥 Clean the nozzles with an open flame (lighter) – even short-term heating deforms the plastic.

⚠️ Warning: If the vacuum cleaner becomes more vibrating or squeezing, you probably damaged the turbine blades, in which case it needs to be replaced, and further operation will lead to engine failure.

Prevention of clogging: how to prolong the life of nozzles

Regular prevention reduces the frequency of cleaning by 2-3 times.

• 📅 Clean the dust collector and filters after each cleaning – this prevents fine dust from entering the nozzles.
• 🧵 Remove hair from side brushes once a week – they are the main source of blockages.
• 🚫 Avoid cleaning construction debris (gypsum, cement, sand) – these materials quickly clog the channels.
• 💧 Do not use too much detergent when wet cleaning – its residues crystallize in nozzles.
• 🔄 Periodically turn on the maximum power mode for 1-2 minutes - this helps to "blown" channels from fine dust.

For self-emptying models (e.g. Xiaomi Mi Robot Vacuum-Mop 2 Ultra):

• 🏠 Clean the docking station once a month - garbage in the container can clog the pneumatic hose.
• 🔌 Check the sealing ring at the junction of the vacuum cleaner and the station - if it is worn out, some of the debris will return to the nozzles.

If you live in a house with animals, it is recommended to:

• 🐕 Use the wool collection nozzles (if they are included in the kit).
• 🧴 Treat brushes with antistatic - this reduces the adhesion of the coat.
• 📅 Clean the nozzles once every 1-2 months (instead of the standard 3-6).

💡

Store the robot vacuum cleaner in a dry place, away from the heating appliances. High humidity contributes to the formation of mold in the nozzles, and overheating - deformation of plastic parts.
