Xiaomi's robot vacuum cleaner has become an indispensable cleaning tool, but its effectiveness has declined over time. One of the main reasons is clogging of the nozzles that blow air through to collect dust. If the device has begun to cope with garbage, makes unusual sounds or leaves behind dirt, it's time to clean. In this article, we'll discuss how to safely clean the nozzles on Mi Robot Vacuum, Viomi, Dreame and other robot vacuum cleaners of the brand without damaging the mechanism.
Many users are afraid to disassemble the equipment for fear of breaking it, but the procedure for cleaning the nozzles is easier than it seems, the main thing is to know the key nuances and use the appropriate tools, we will describe each step in detail, warn against typical errors and give tips for care so that your vacuum cleaner lasts longer.

Why do the nozzles get clogged and how it manifests itself
The nozzles (or air channels) of Xiaomi’s robot vacuum cleaner get clogged over time for several reasons:
- 🌫️ Fine dust and wool are the main enemies of the system, and they penetrate into narrow holes and compact to form traffic jams.
- 🧹 Large debris (hair, thread, paper) can wrap around the turbine and block the airflow.
- 💧 Wet cleaning (for models with the function of washing floors) leaves a plaque that sticks to the walls of the channels.
- ⏳ Long-term use without maintenance – even if the vacuum cleaner works “like new”, dirt accumulates inside.
The signs that the nozzles have clogged are as follows:
- 🔊 Increased noise during operation (the turbine is working for wear and tear).
- 🌀 Reduced suction force - vacuum cleaner worse picks up garbage from carpets.
- 🚫 Error stops (e.g. code) 02-03 The display indicates an airflow problem).
- 🌪️ Blowing dust back - instead of suction, garbage flies from under the vacuum cleaner.
If these symptoms are ignored, the consequences can be serious, from engine overheating to turbine failure, which will cost half the cost of a new vacuum cleaner. Z10 Pros are particularly sensitive to clogging due to compact air channels.
⚠️ Warning: If the vacuum cleaner starts to make a whistling sound when working, this is a sure sign of critical clogging of the nozzles!

Before starting work, disconnect the vacuum cleaner from the charging station and remove the battery (if possible without disassembly).
Step 1 Removing the bottom cover
- Turn the Xiaomi vacuum cleaner upside down.
- Unscrew all the screws around the perimeter (usually 4-6 pieces). L10) The lid is attached to the latches - carefully put it with a plastic card.
- Remove the lid and put it aside.
Step 2. Access to nozzles
- The nozzles are located next to the turbine (a round plastic block with blades).
- In some models, they are closed with an additional protective net - it must be carefully removed.
Step 3. Clean the nozzles.
Remove large rubbish with tweezers|
Clean the holes with a needle or toothpick|
Wash removable parts in a soapy solution|
Rub the plastic with a microfiber wipe|
Blow the channels with a vacuum cleaner (at minimum power)-->
For deep cleaning:
- Wet your toothbrush in soapy solution and gently clean the inner walls of the nozzles.
- If the clog is severe, soak the removable parts in warm water for 10-15 minutes.
- For models with wet cleaning function (Viomi) V3, Xiaomi Mop 2 Pro) wash the water tank and tubes with acetic solution.
Step 4.
- Before installing the cover, make sure all parts are dry.
- Twisting the screws cross-cross to avoid distortion.
💡
If after cleaning the vacuum cleaner still poorly sucks, check the filter HEPA — It should also be washed or replaced every 3-6 months.

Features of cleaning for popular Xiaomi models
The design of the injectors may vary depending on the model, and let's look at the nuances for the most common robot vacuum cleaners:
| Model | Design features | Cleaning recommendations |
|---|---|---|
| Xiaomi Mi Robot Vacuum-Mop 2 Pro | The nozzles are integrated into a single unit with a turbine, a removable protective grille. | Clean the grille separately, blow the turbine with a vacuum cleaner at minimum power. |
| Dreame Bot Z10 Pro | Two side nozzles for increased suction at the edges, sensitive to hair. | Pay special attention to the side channels - they clog faster. |
| Viomi V3 | Wet cleaning system with separate tank, nozzles are located closer to the back. | After cleaning, be sure to wash the water tubes with citric acid. |
| Xiaomi Mi Robot Vacuum 1S | Simple design, but narrow air channels. No removable grille. | Use the needle for cleaning, avoid strong mechanical impact. |
For models with a laser rangefinder (such as the Xiaomi Mi Robot Vacuum-Mop P), be careful when disassembling – do not touch the lens or expose it to moisture.
How to Clean Your Nozzles in Dreame Bot L10:
⚠️ Note: In Xiaomi models with container auto-emptying (e.g. DreameBot) X30) The nozzles are connected to the pneumatic system. Don't use water to clean them, just dry cleaning!

Frequent Mistakes and How to Avoid Them
Even experienced users sometimes make mistakes when cleaning injectors that lead to breakdowns.
1. Use of sharp objects
Many try to clean the holes with a knife or scissors, resulting in scratches on plastic or damage to sealing gums.Solution: only use wooden toothpicks or plastic tools.
2. Washing of non-removable parts
Some parts (such as a turbine or sensors) can't be wetted, and if water gets on the board, it will cause a short circuit, solution: Clean the non-removable parts only dry (brush or vacuum).
3. Wrong assembly
If you forget to install a protective grille or twist the screws loosely, the vacuum cleaner will give an airflow error (02-03 or 05-01). Solution: Take photos of the disassembly process or take a video.
4. Cleaning without power outage
If you start disassembling the vacuum cleaner without taking the battery out, accidentally pressing a button can turn on the turbine, which will cause injury or breakage of the blades, so you can always remove the battery or at least press the power button for 10 seconds to completely shut down.
5. Ignoring filters
Many people only clean the nozzles, forgetting about the filter. HEPA This leads to rapid re-clogging, so you can change the filters every 3 to 6 months (depending on the intensity of use).

Prevention: how to prolong the life of nozzles
To avoid having to clean the nozzles often, follow these tips:
- 📅 Regular maintenance – clean the vacuum cleaner every 1-2 months, even if there are no visible problems.
- 🧹 Pre-cleaning – remove large debris (wires, toys) from the floor that can clog channels.
- 🔄 Use the right nozzles - for carpets, turn on Max mode, for smooth surfaces - Standard.
- 🚫 Avoid wet cleaning on carpets - this leads to dirt sticking on the nozzles.
- 🔋 Watch the charge – a discharged battery makes the turbine work at its limit, accelerating clogging.
For models with auto-emptying (DreameBot) X30, Viomi Alpha):
- 🗑️ Empty the main container every 3-5 times, even if it is not full.
- 🧼 Wash the dust collector with water only - detergents can damage sensors.
How often to change the consumption:
| Detail | Recommended frequency of replacement | Signs of wear and tear |
|---|---|---|
| HEPA filter | Every 6 months | Reduced absorption, unpleasant smell |
| Pre-filter | Every 3 months | Visible dirt, obstructed airflow |
| Side brushes | Every 6-12 months | Brushed bristles, creaking when rotating |
| Main brush. | Every 12 months. | Loss of elasticity, cracks on rubber nozzles |
💡
Regular cleaning of nozzles and replacement of filters increases the life of the robot vacuum cleaner Xiaomi by 30-50%.
