Specifications of Xiaomi Mi Electric Toothbrush X3U: What you need to know before using

Before you start cleaning, it's important to understand the capabilities of your device. - Xiaomi X3U It's equipped with a brushless magnetic levitation motor that can go up to 31,000 vibrations per minute, which is 20 percent higher than most low-end models, and it's more efficient at removing plaque, but it requires caution when it comes to sensitive gums.

Key parameters of the model:

• 🔋 Battery: Lithium-ion, capacity 800 mAh, the charge is enough to 25 days with double cleaning 2 minutes (real tests show) 18-20 days with intensive use).
• 💧 Waterproof: standard IPX7 — brush can be completely immersed in water to a depth of 1 meter (but it is not recommended to leave in water for a long time).
• ⚙️ 3 pre-installed modes (Standard, Soft, Clean) + The ability to adjust the intensity through the Mi Home app.
• 🔄 Timer: built-in smart timer with intervals of 30 seconds for uniform cleaning of all areas of the oral cavity.

Feature X3U — A pressure sensor that alerts you to flash if you press your brush too hard against your teeth, which protects enamel from microcracks and gums from recession. However, the sensor only works if the threshold of 200 grams is exceeded, which is higher than the recommended 150 grams by dentists - this is worth remembering for users with sensitive gums.

Preparation for cleaning: choice of nozzle, toothpaste and additional accessories

The quality of cleaning is 40% dependent on the right nozzle. - Xiaomi X3U complete with a standard nozzle W1 with soft bristles, but there are other options in the lineup:

Important: Xiaomi nozzles are only compatible with the brand's original models. Using analogs can lead to uneven engine wear due to differences in weight and balancing. When buying, check the labeling - fakes often have duller plastic and coarse bristles.

For toothpaste: for electric brushes, only low-abrasive pastes with RDA higher 50-70 (for example, SPLAT Biocalcium or PresiDENT Sensitive, whitening pastes (RDA >100) can damage enamel with intense brush fluctuations. Also avoid pastes with large particles (for example, with salt or activated carbon) - they get clogged between the bristles and shorten the life of the nozzles.

💡

Before the first cleaning, wash the nozzle in warm water with soap - this will remove the factory lubricant, which can give an unpleasant taste.

Step-by-step: how to properly brush your teeth with Xiaomi brush X3U

The electric brush is fundamentally different from the manual brush, and the rule is, you don't have to make circular movements, you have to do up to 31,000 microvibrations per minute, and your job is to position the nozzle properly and move it slowly from tooth to tooth.

The algorithm for proper cleaning:

Prepare the brush (charge, install the nozzle, apply the paste)|Include a brush before applying to your teeth (to avoid splashes)|Start with the upper jaw, the outer surface of the teeth|Hold the brush at an angle of 45° gum-to-mum|Move in quadrants (30 seconds each)|Do not forget about the inside of the teeth and the chewing surface.|Complete your tongue cleaning (if there is a special nozzle)|Wash the brush and nozzle under running water-->

More information on the key stages:

1. Inclination angle: hold the brush at an angle of 45° This allows the bristles to enter the gum gutter and remove plaque at the base of the teeth.
2. Pressure: Don't press the brush -- a light touch is enough. If the indicator on the brush flashes red, ease the pressure.
3. Move your brush slowly from one tooth to the other, lingering on each tooth 2-3 No need to scrape or rub -- vibration will do the work for you.
4. Cleaning order: Dentists recommend starting with the upper jaw, the outer surface, then the inner, then the lower jaw, and chewing surfaces are cleaned last.

Pay special attention to the bass cleaning technique, which is ideal for electric brushes:

1. Place the bristles so that they partially capture the gums.
2. Turn on the brush and hold it still. 5-10 seconds.
3. Smoothly move to the next tooth without tearing the bristles from the surface.

This method removes plaque from under the gums and improves microcirculation, but requires skill.

Xiaomi modes of operation X3U: which to choose and when

The brush offers 3 main modes, which differ in intensity of vibrations and are designed for different tasks:

1. Standard (Standard)

• 🔄 31,000 oscillations / min - the optimal balance of efficiency and care.
• ⏱️ Cleaning time: 2 minutes at intervals of 30 seconds.
• 🦷 Suitable for daily use with healthy teeth and gums.

2. Soft (Soft)

• 🔄 24,000 oscillations/min - reduced intensity.
• 🩹 Recommended for bleeding gums, after dental procedures (such as whitening), and for children over 6 years of age.
• ⚠️ Not suitable for removing old plaque in smokers.

3. Clean (Intensive)

• 🔄 33,000 vibrations/min - maximum power.
• ☕ Ideal for removing plaque from coffee, tea, red wine.
• ⚠️ Not to use more than 2 times a week - can cause increased tooth sensitivity.

Hidden function: if you hold the switch on 3 seconds, the brush will go into "User" mode, where you can manually adjust the intensity from 18,000 to 33,000 vibrations / min. This is useful for adapting to a new brush or temporary discomfort in the gums.

💡

For maximum effect, alternate regimens: use Clean 1 time a week for deep cleaning, and on the other days - Standard. This prevents bacteria from getting used to one type of exposure.

Common Mistakes When Using Xiaomi X3U and how to avoid them

Even experienced electric brush users often make mistakes that negate the benefits of the device.

⚠️ Warning: Never turn on the brush when it is already in your mouth. A sudden onset of vibration can cause mucosa injury (cuts or abrasions) or chipping of the filling. Always run the brush outside the mouth and only then bring it to your teeth.

Mistake 1: Excessive pressure

Many people mistakenly believe that the harder you press a brush, the better it cleans.

• 🦷 Pressure. >200 g leads to the erasure of enamel in the cervical region (at the base of the tooth).
• 🩸 Can cause a gum recession - baring the root of the tooth, which increases sensitivity.
• ⚡ Reduces the life of the engine due to increased load.

How to avoid: Watch the pressure indicator. If it flashes red, relax the grip.

Mistake 2: Wrong position of the brush

Many people hold the brush parallel to their teeth, which reduces the cleaning efficiency by 40 percent.

• 📐 Corner 45° to the surface of the tooth (bristles should partially capture the gums).
• 🔄 For chewing teeth – the position of the brush vertically, with an emphasis on fissures (deepening).

Mistake 3: Ignoring the timer

The built-in timer is divided into 30-second intervals, and that's not accidental. Each quadrant of the jaw (upper right, upper left, etc.) needs a separate attention, and by skipping the timer, you leave up to 30 percent of the surface of your teeth uncleaned.

⚠️ Note: Don’t use Xiaomi X3U For dentures or braces, without any special attachment, vibration can weaken the fixation of structures or damage silicone elements. S1.

• 🧼 Once a week, disinfect the nozzle in a solution of hydrogen peroxide (3%) or a special cleaner for toothbrushes.
• 🌬️ Dry the nozzle vertically in a glass with vents. Closed cases provoke bacterial reproduction.

2.The maintenance of the hull

• 🔍 The hairs have lost their shape and are “swelled".
• 🦠 It smelled like a smell even after washing.
• 🩸 The gums began to bleed when brushing (a sign of blunt bristles).

Tip: In the Mi Home app, you can include a reminder to replace the nozzle.The algorithm tracks the time of use and sends a notification when the deadline is right.
