Replacement of the nozzle on the toothbrush Xiaomi: instructions for all models

Xiaomi's electric toothbrushes are a popular choice among those who value technology and convenience. But even the most advanced device requires regular maintenance, and replacing the nozzle is one of the key procedures. Why is this so important? Over time, the bristles wear out, lose stiffness and stop cleaning teeth effectively. In fact, the nozzle accumulates bacteria that can adversely affect oral health.

In this article, we will discuss in detail how to remove the old one and install a new nozzle on different models of Xiaomi toothbrushes - from the budget Mi Electric Toothbrush T100/T300 You will also learn how often to change the nozzles, what kinds exist and how to avoid typical replacement errors.

Why is it important to change the sleeve in time?

Many users of electric toothbrushes underestimate the importance of replacing their nozzles in a timely manner, while dentists recommend updating them every time. 2-3 This is how long it takes to lose the hair. 50% And that's the key reason why it's critical:

• 🦠 Bacterial pollution: even with regular cleaning, microorganisms remain on the nozzle that can cause inflammation of the gums and caries.
• 🪥 Decreased cleaning efficiency: worn bristles penetrate the interdental spaces worse and do not remove plaque completely.
• 🩹 Risk of gum injuries: deformed bristles can scratch the mucous membrane, provoking bleeding.
• 💡 Worsening brush: on some Xiaomi models (e.g. Oclean) W10) worn-out nozzle can cause vibrations and noise.

Fun fact: Studies show that after 3 months of use, up to 10 million bacteria can accumulate on the nozzle, including Streptococcus mutans, the main culprit of tooth decay. That's equivalent to the number of microbes in the public toilet seat! So replacing the nozzle is not only hygiene, but also the prevention of dental problems.

⚠️ Note: if you have recently undergone dental surgery (such as tooth extraction or implantation), the nozzle should be replaced immediately after recovery.

What are the best tips for Xiaomi toothbrushes?

Xiaomi has several lines of electric toothbrushes, and each one has compatible nozzles. It is important to understand that not all consumables are universal - for example, the Mi Electric Toothbrush nozzle. T100 It is not suitable for Oclean X Pro. Below we will discuss the main types and their features.

Apart from the original nozzles, there are compatible third-party nozzles on the market (like Fairywill or Colgate) which are cheaper, but the quality may vary. Xiaomi's original nozzles are usually labeled with the MJSTQxWM or OC-Mx code - pay attention to this when buying.

Step-by-step: how to remove the old nozzle

The process of removing the nozzle may vary slightly depending on the brush model, but the general principle is the same. The main thing is not to make excessive efforts to avoid damaging the mount.

1. Turn off the brush. If it's on, press the power button and wait for a full stop. On some models (e.g. Oclean). W10) When you try to remove the nozzle during operation, a lock can work.
2. Hold the brush body with one hand and the other gently pull the nozzle upwards (for straight-mount models) or counterclockwise (for threaded-connect models like the Mi). T700).
3. If you need to use a tool, if the nozzle is "stiff" (this happens with prolonged use), you can use pliers with soft sponges or a special removable (company with some models), hold the nozzle at the base and scroll carefully.

On magnetically attached models (such as the Oclean X Pro), just pull the nozzle upwards, the magnets will weaken the fixation. If you feel resistance, don't pull sharply: try to sway the nozzle slightly from side to side.

⚠️ Warning: Never use metal tools (screwdrivers, knives) to remove the nozzle - this can damage the thread or magnetic attachment. If the nozzle does not lend itself, it may have deformed due to overheating (for example, if the brush has been lying for a long time in direct sunlight).

How to install a new nozzle: nuances for different models

Installing a new nozzle is usually easier than removing the old one, but there are also some subtleties.

1. Directly fastened brushes (Mi) T100/T300)

And these models are fixed by a tight pin landing, to get a new one.

1. Combine the nozzle hole with the pin on the brush.
2. Press down to a characteristic click (effort should be moderate).
3. Check the fixation by slightly pulling the nozzle up.

Folded brushes (Mi) T700, Soyee S1)

Here the nozzle is wound up on the base:

1. Put the nozzle on the thread and press slightly.
2. Turn the clockwise hand to the point (do not pull!).
3. Make sure the nozzle sits flat and doesn't hang around.

3. Magnetic fastening brushes (Oclean) X/X Pro/W10)

The magnetic mount is the simplest:

1. Hold the nozzle to the base - the magnets will attract it themselves.
2. Then, with a light tap, lock it before you click.
3. Check that the nozzle does not scroll around the axis.

Important: After you install the new nozzle, turn on the brush and check if there is any extraneous vibration or noise, if they appear, then the nozzle is installed incorrectly or defective.

💡

Before the first cleaning with a new nozzle, wash it under warm water with soap - this will remove factory lubrication and possible microcontamination.

Frequent Mistakes When Replacing a Nozzle and How to Avoid Them

Even a simple procedure like replacing a nozzle can go wrong, unless you take into account some nuances. Here are the most common mistakes and ways to prevent them:

• 🔧 Tug the threaded joint: this can cause the mount to break. Twisting the nozzle to the point, but without fanaticism - a tight enough fixation.
• 🧲 Incomplete magnetic attachment: If there is no click, the nozzle may fly off during cleaning. Always check the fixation before using.
• 🚿 Ignoring fastening brushing: The thread or pin accumulates plaque over time, which prevents a tight fit. Periodically clean the fastening with a cotton swab dipped in alcohol.
• 🔄 Using nozzles from other brands without compatibility checks: for example, nozzles from Oral-B will not suit Xiaomi - they have a different mount diameter.

Another common problem is when you get backlash after you change the nozzle, and it can be because of:

• The stain on the sleeves (often found after the 2-3 years);
• defect of the new nozzle (for example, a mismatch in the diameter of the hole);
• Incomplete fixation (especially relevant for magnetic models).

If the backlash appears immediately after replacement, try reinstalling the nozzle. If the problem persists, check if the warranty period for the brush has expired (usually). 12-24 In some cases, Xiaomi replaces the mount for free under warranty.

How do you care for the stains so they last longer?

The life of the nozzle depends not only on the frequency of use, but also on the proper care. Here are some tips to help extend the life of consumables:

• 💧 Wash after each use: rinse the nozzle under running water to remove paste residues and plaque. 3% hydrogen peroxide can be used to disinfect (soak for 5 minutes 1 time per week).
• 🌬️ Dry properly: do not store the brush in a closed case - moisture promotes the reproduction of bacteria.
• 🔥 Avoid high temperatures: Do not leave your brush under direct sunlight or near heating appliances – this can deform bristles.
• 🧴 Do not use abrasives: a soft toothbrush and soap solution are enough to clean the nozzle. Hard brushes or powders will damage the bristles.

Interesting life hack: if you use an ultraviolet sterilizer for toothbrushes (for example, Xiaomi Viomi) UV Sterilizer, it is enough to process the nozzle in it 1 time every 3 days - it kills up to 99.9% of bacteria and allows you to change consumables less often.

⚠️ Warning: Never boil disinfection nozzles, which breaks down the bristles and can deform plastic. The maximum permissible temperature for most models is 60.°C.
