How to properly lubricate Xiaomi electric razor: instructions with photos and videos

Xiaomi electric shavers are a combination of affordable price and high quality, but even the most reliable technique requires maintenance. Knives lubrication is a key process that prolongs the life of the device, prevents overheating and ensures smooth slip of the blades. Many users ignore this procedure until the razor begins to "squeak", pull hairs or worse to cope with shaving. In fact, regular lubrication (every 3-6 months) can save you money on repairs or buying a new razor.

In this article you will find step-by-step instructions for lubricating popular models Xiaomi Mi Electric Shaver, Mijia Enchen and others, and also understand what lubricant to choose, how to avoid errors and what to do if the razor has already “buzzed” like a tractor. We will not limit ourselves to general tips – here only proven methods taking into account the features of Xiaomi equipment.

If you've never lubricated a razor yourself, don't worry: it's easier than it looks. The main thing is to take your time and follow the recommendations. And if your razor already requires "resuscitation," at the end of the article there's a section on how to bring it back to life even after a long period of untreated downtime.

Why should Xiaomi electric shavers be lubricated?

An electric shaver is a mechanism with moving parts that are subject to friction and wear. Without lubrication, metal knives and nets rub against each other, leading to several problems:

✅ Overheating of the engine. With dry friction, the engine has to work with increased load, which reduces its life, especially in low-end Xiaomi models, where the cooling system is simplified.

✅ Deterioration of shaving quality: blunt or jammed knives do not cut hairs, but pull them out, which causes discomfort and irritates the skin.

✅ Corrosion and oxidation. Wet environments, if you wash a razor under the tap, accelerate the rust of exposed surfaces. Lubrication creates a protective layer.

✅ Increased noise, a characteristic "squeal" or hum when working is a sure sign that the knife is lacking lubrication, and in advanced cases, the razor may even "jump" in the hand.

Xiaomi manufacturer in the instructions for most models (for example, Mi Electric Shaver) S500 or Mijia Enchen T500) indicates that lubrication is required every 6 months with regular use, however, if you shave daily or have a stiff stubble, the interval should be reduced to 3-4 months.

What kind of lubricant to choose for Xiaomi razor?

Not all lubricants are suitable for an electric shaver.

• 🔹 Specialized – should be designed specifically for razors (not to be confused with engine oil or WD-40!).
• 🔹 Smellless and colorless – aggressive additives can corrode plastic or cause allergies when in contact with skin.
• 🔹 Viscosity - too liquid lubricant quickly drains, thick - will make it difficult to move knives.
• 🔹 Anti-corrosion properties - protects against rust when washing a razor.

Here are the best options for Xiaomi razors (tested on models) S500, T500, Enchen T300):

Important: Never use sunflower oil, petroleum jelly or WD-40! These substances thicken, attract dust and can spoil the razor mechanism.

If you can't find a specialty lubricant, you can temporarily use silicone oil for sewing machines (sold in hardware stores), which is plastic- and metal-neutral, but does not offer the protection that professional formulations offer.

💡

Before buying, make sure the lubricant packs are labeled "Electric Shaver" or "Food-grade" to ensure that the composition does not harm the skin.

Preparing Xiaomi razor for lubrication: disassembly and cleaning

Before applying the lubricant, the razor must be thoroughly cleaned of hairs, dust and old lubricant. By skipping this stage, you risk "sealing" the dirt inside the mechanism, which will only worsen its operation.

Step-by-step training:

1. Turn off the razor and take out the battery (if the model is collapsible, for example, Xiaomi Mi Electric Shaver). 1S).
2. Remove the knife unit. Most Xiaomi models have it on the latches -- press the buttons on the sides and pull it up.
3. Remove visible hairs with a brush (comes with a kit) or compressed air (a canister for cleaning equipment).
4. Wash the knives and nets under warm water with soap (if the model is waterproof). Use alcohol wipes for non-waterproof razors.
5. Dry all the details in the air for 10-15 minutes or use a dryer (cold mode!).

⚠️ Note: If your Xiaomi razor doesn’t support wet cleaning (e.g., older Mi Electric Shaver models without labeling) IPX7), Don't wash it underwater! Moisture will get into the engine and it will knock the device out.

For deep cleaning, you can use an ultrasonic bath (if you have a home), pour water with a drop of dishwashing agent into it and place the knife unit for 2-3 minutes, then rinse the parts with clean water and dry.

Step-by-step: how to lubricate Xiaomi electric razor

Now, the key thing is to apply the lubricant, and the important thing is, don't rush and get too much quantity, and the excess oil is just as bad as the lack of oil, and it will spray when you're working and attract dust.

Algorithm of action:

1. Lubrication on knives: 🔧 If you use a spray, spray 1-2 short presses 5-10 cm from the knife unit! 💧 If the oil is in the bottle - drop 1-2 drops on each blade and on the places of fixing the net.
2. Lubrication Distribution: Manually twist the knives with a blunt object (such as a plastic stick) or turn on the razor for 5-10 seconds so that the oil is evenly distributed. Make sure that the lubricant covers all rubbing surfaces, but does not drain out in drops.
3. Assembly: Set the knife unit back before the click. wipe the razor body with a napkin to remove excess oil.

Verification

• Turn on the razor and let it work for 1-2 minutes. The noise should be quieter, the vibration should be smoother.
• If the razor sneezes or twitches, it means too much lubrication. Remove the excess with a napkin.

⚠️ Attention: If the razor becomes worse after lubrication (for example, the knives "slipped"), then you used the wrong composition or overdo it with the amount. In this case, disassemble the razor again and wipe the knives with alcohol, then apply the lubrication again - but more economically.

Features of lubrication for popular Xiaomi models

Not all Xiaomi razors are the same, they have different knife designs and moisture protection levels.

1. Xiaomi Mi Electric Shaver S500 / S501

• 🔹 The knife unit is removed by pressing two side buttons.
• 🔹 Supports wet cleaning (IPX7), So you can wash it underwater.
• 🔹 Lubrication is applied to three moving blades and guide nets.

2. Mijia Enchen T500 / T300

• 🔹 The block is attached to one central latch (pull up).
• 🔹 There is no protection from water – cleaning is dry only!
• 🔹 Requires lubrication once every 3 months due to the high speed of rotation of the knives.

3. Xiaomi Mi Electric Shaver 1S (budgetary model)

• 🔹 Knives are fixed by a magnet - removed easily, but carefully.
• 🔹 The engine is weaker than that of flagships, so overheating due to dry friction comes faster.
• 🔹 It is better to use liquid oil rather than spray (less risk of getting on the engine).

4. Xiaomi Mijia Smart Electric Shaver (with Bluetooth)

• 🔹 Has a sensor of wear of knives - if necessary, lubricants can notify through the Mi Home app.
• 🔹 Knife block is indissoluble - lubricate only through the upper holes.

If you are not sure about your razor model, check its name on the box or in the settings of the Mi Home app (for smart models), and you can also enter the serial number on the Xiaomi website to clarify the characteristics.

💡

For models with IPX7 (Water protection, you can use a silicone-based lubricant that doesn't flush when you wash it, and only dry lubricant (e.g. Teflon) is suitable for non-water-resistant razors).

Frequent Lubrication Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes that instead of benefit harm the razor.-5 Failures and how not to repeat them:

🚫 Too much lubrication

Excess oil drains onto the engine, attracts dust and can cause a circuit. Normal: 1-2 drops per knife unit (no more!).

🚫 Use of inappropriate compositions

WD-40, Vaseline or vegetable oil thickens and spoils the mechanism. Solution: buy only specialized lubricants (see table above).

🚫 Lubrication of a dirty razor

Applying oil to unpeeled knives is like pouring gasoline into a clogged filter. Right: cleaning first, then lubricating.

🚫 The hit of lubrication on the contacts of the battery

This can cause oxidation or poor contact, and avoid it by removing the battery before lubricating it or by tapering the contacts.

🚫 Ignoring Test Launching

After lubrication, be sure to turn on the razor for 1-2 minutes so that the oil is distributed. If not, the grease may splash on the first shave.

⚠️ Warning: If the razor becomes worse shaving after lubrication or the smell of burning appears, immediately disassemble it and remove all the lubrication with alcohol.

How to care for Xiaomi razor after lubrication?

Lubrication is only part of the care. To make the razor last longer, follow these recommendations:

🔋 Charging the battery

• 🔌 Do not keep the razor constantly on charge - this reduces the battery life.
• 🔋 Optimally charge up to 80% and discharge up to 20% (like smartphones).

🚿 Cleaning after every shave

• 🧹 Remove the hairs with a brush from the kit.
• 💦 If the model is waterproof, rinse under the tap once a week.

🔄 Replacement of knives

• ✂️ Knives wear out even when well maintained.For Xiaomi models, the recommended replacement time is 18-24 months.
• 🛒 Original knives for Mi Electric Shaver can be ordered on AliExpress or in Xiaomi branded stores.

🌡️ Storage

• 🏠 Keep your razor in a dry place, away from direct sunlight.
• 📦 If you do not use for a long time (for example, on vacation), lubricate the knives and store them in a case.

📱 For smart models (with Bluetooth)

• 📲 Regularly update the firmware through the Mi Home app – this improves engine performance.
• 🔍 Watch out for alerts about knives wear or lubrication need.

If you follow these rules, your Xiaomi razor will last 5 years or more without serious damage, and if something goes wrong, in the next section we will tell you how to "resuscitate" a buzzing or jammed razor.

What to do if Xiaomi razor is already “screaking” or not shaving?

If you haven't been lubricating a razor for a long time and it's now intermittent, don't throw it away. In most cases, the device can be brought back to life. Here's the plan:

🔧 1. Deep cleaning

• Disassemble the knife block and soak it in a solution of vinegar and water (1:1) for 10 minutes - this will remove rust and old lubricant.
• Use a toothpick to clean hard-to-reach places.

🛠️ 2. Knives wear check

• If the blades have serrated or severe corrosion, it is better to replace them.
• For models Xiaomi Mi Electric Shaver suitable knives from Philips (for example, series). 3000/5000) — They're compatible.

⚡ Engine inspection

• If the razor doesn't turn on or if it's jerking, the problem may be the battery contacts.
• If the engine is buzzing, but the knives are not rotating, the gear may have broken, in which case you need to change the mechanism (call the service).

🔄 4. Re-lubrication

• After cleaning, apply the lubricant (as described above) and let the razor work for 5 minutes idling.
• If the noise is not gone, repeat the procedure every other day (maybe the oil has not yet been distributed).

⚠️ Attention: If after all the manipulations the razor still does not shave or makes a grin, do not try to disassemble it further - contact the service center.

💡 Tip: If your Xiaomi model is still under warranty, do not disassemble it yourself - this will void the warranty. Better take it to an authorized service (the list is available on the Xiaomi Russia website).

💡

In 80% of cases, Xiaomi’s dying razors can be restored with deep cleaning and proper lubrication. Don’t rush to buy a new one – try resuscitating the old one!
