Disassembling the brush Xiaomi T100: a complete guide with expert advice

Why to disassemble the Xiaomi T100 brush and when it is necessary

The Xiaomi T100 electric brush is a popular device for the care of shoes, clothes and furniture, but even the most reliable equipment requires maintenance. Disassembly can be necessary in several cases: for deep cleaning of internal mechanisms from accumulated dust, replacing worn brush nozzles or repairing the electric motor when power is lost. Most often, users are faced with the fact that the brush begins to work in jerks, makes extraneous sounds or refuses to turn on altogether – all these are signals that it is time to look inside.

It is important to understand that the Xiaomi T100 is not a β€œdisassembly” technology, but its design is not the easiest. The manufacturer does not provide official instructions for disassembly, so you will have to act at your own risk. However, with the right approach and the presence of a minimum set of tools, the process will not take more than 30-40 minutes.

If you’ve never been to a household appliance before, we recommend that you first review the frequent questions at the end of this article, and here we’ve collected answers to common novice mistakes, such as how to avoid damaging plastic latches or what to do if the brush doesn’t turn on after assembly.

Preparation for disassembly: tools and security measures

Before you start disassembling, make sure you have everything you need on hand, and without the right tools, you risk damaging the body or the interiors, and here's the minimum set you'll need:

  • βœ… Plastic mediators or shoulder blades (to separate the latches of the body without scratches).
  • βœ… Cross screwdriver (usually suitable size) PH0 or PH1).
  • βœ… Tweezers (to extract small parts, such as springs or contacts).
  • βœ… Multimeter (if you plan to check the circuits or engine).
  • βœ… Silicone mat or soft fabric (so as not to scratch the body and lose screws).

Also, prepare the workplace: it should be well lit and spacious. Decompose tools in order of use, and fold the brush parts into separate containers (for example, bags with stickers) – this will help not to confuse them when you reassemble.

⚠️ Warning: Never disassemble a brush if it's connected to the grid or the battery isn't removed! Even when it's off, there may be residual charges on the board that lead to a short circuit.

Step-by-step: how to disassemble the body of the Xiaomi T100

The body of the brush consists of two main parts: the upper (with the power button) and the lower (with the engine and the brush unit), disassembly begins with the separation of these parts.

  1. Take the brush nozzle off. Pull it on you, it's mounted on the guides, and it should be easy to separate. If the nozzle is boiling, gently swing it left and right.
  2. Remove the battery. In the T100, the battery is removable: press the lock at the bottom of the handle and pull out the battery pack.
  3. Unscrew the screws. Turn over the brush and unscrew the 4 screws on the bottom cover (they can be hidden under the rubber legs - gently tuck them in).
  4. Separate the case. Put the plastic mediator in the gap between the top and bottom of the case and guide them gently around the perimeter, snapping the clamps. Start from the side opposite the switch.

If the body doesn't lend itself, don't use excessive force! You may have missed one of the screws or latch. Notice the area around the power button -- there's often an extra lock hidden there.

Make sure the brush is off the network

Remove the brush nozzle

Remove the battery

Unscrew all screws (including those hidden under the legs)

Prepare a plastic mediator for latches-->

Once the body is disassembled, carefully put the top to the side, and now you will see the inner "stuffing" of the brush: the control board, the engine and the mechanism for transferring rotation to the brush.

Diagnostics and cleaning of internal components

One of the main reasons for the disassembly of the Xiaomi T100 is the contamination of the internal mechanisms, and dust, hair and small debris eventually penetrate the body, settling on the engine and gears, which leads to overheating, loss of power and unstable operation.

  • πŸ”§ Engine: Blow it with compressed air (like a can of cleaning equipment) or gently remove the dust with a soft brush!
  • βš™οΈ The gears and gearbox, check if they're not wearing dried dirt or chipped, and if they're worn out, they might need to be replaced.
  • πŸ”Œ Contacts of the board: Oxidized or contaminated contacts can cause unstable nutrition.
  • 🧲 Magnets in the brush block. Make sure they don't shift or lose their gravity (this affects the quality of garbage collection).

If the brush was jerking or not working at all, check the condition of the engine brushes (graphite contacts). Over time, they wear off and have to be replaced.

  1. Remove the rear cover of the engine (usually it is attached to 2-3 screws).
  2. Remove the rotor and inspect the brushes. If they are less than 5 mm long, replacement is required.
  3. Install new brushes (you can order by art. XMT-005 for Xiaomi T100).

⚠️ Warning: When cleaning the engine, do not use metal objects (screwdrivers, knives) - they can damage the winding. Also avoid moisture on the board: even drops of alcohol can cause corrosion of contacts.

πŸ’‘

If the engine is still unstable after cleaning, check the condition of the bearings. When worn, they start to "buzz" at high speeds, grease them with silicone lubrication or replace them with strong backlash.

Replacement of the brush unit and other consumables

The brush unit is a waste product that wears out over time. In the Xiaomi T100, it consists of two parts: a rotating brush (with a pile) and a magnetic drum (for collecting garbage). Replacing the unit does not require a complete disassembly of the body, but if you have already reached the insides of the brush, it makes sense to check other consumables:

DetailSigns of wear and tearHow to replaceOrder article
Brush blockWorth stuck, brush doesn't rotate, picks up garbage badlyRemove the old block, install the new one before clickingXMT-BRUSH-100
HEPA filterIt's clogged with dust, the air is not good.Remove from the compartment, install a new oneXMT-FILTER-100
BatteryIt discharges quickly, does not hold the charge.Disconnect the connector, connect a new oneXMT-BAT-18650
Rubber sealsCracked, dusted, cracked.Remove old ones, install new ones on glueXMT-SEAL-KIT

When you replace your brush, look for magnetic stripes that should fit tightly into the drum. If the magnets are weakened, the brush will not be able to collect garbage, and in this case, you can try to remagnetize them with a neodymium magnet (sold in radio parts stores).

If you notice that after the brush has been replaced, it has become louder, check the balance of the drum. Sometimes the new unit can be set curve, which leads to vibrations. Carefully twist the drum with your hand - it should rotate smoothly, without jamming.

What to do if the new brush unit is not suitable?
Sometimes users are faced with the fact that the purchased unit does not sit down. The reason is usually due to different brush revisions. Xiaomi T100 was released in several versions, and the brush blocks for them may differ in the length of the shaft. Solution: 1. Check the marking on the old block (for example, "V2.1"). 2. Check with art. XMT-BRUSH-100 - the description should indicate which revision it is suitable. 3. If the block is still not suitable, contact the seller for a replacement or buy a universal analogue (for example, from Baseus).

Assembly of the brush after repair or cleaning

Building the Xiaomi T100 is as important as disassembling, and the rule of thumb is to reverse and check every step.

  1. Set the control board. Make sure all the connectors (power, motor, buttons) are tightly connected. Check if the wires are twisted.
  2. Hold the engine. It should sit in the slots without backlash. Tighten the screws cross-to-cross to avoid distortion.
  3. Set up a brush unit. Scroll it manually, it should rotate freely.
  4. Start by snapping the top, then twist the screws. Don't drag them over!

After assembly, be sure to check the brush idling (without a nozzle) before installing it back. If you hear foreign sounds (squeaking, knocking), disassemble the device again - most likely, somewhere skewed the part or forgot to connect the connector.

If the brush does not turn on after assembly, check:

  • πŸ”‹ Battery condition (possibly discharged or in poor contact).
  • πŸ”Œ Connecting the power button (often the connector leaves when assembled).
  • πŸ› οΈ Integrity of the fuse on the board (with a short circuit it could burn out).

πŸ’‘

The most common build error is that the power button connector is not connected correctly, and it must enter the socket on the board before the characteristic click, and if the contact is weak, the brush may turn on once or not respond to the press.

Frequent breakages Xiaomi T100 and how to avoid them

Even with careful operation Xiaomi T100 It can go down over time.-5 Disruptions faced by owners and ways to prevent them:

  1. Reason: Wearing gears of the gearbox or breaking the drive belt. Prevention: Clean the gearbox regularly from dust and avoid pressing the brush hard while you're working.
  2. Poor suction power. Cause: Clogged filter or loss of magnetic properties of the drum. Prevention: Change the filter every 3-6 months, check the magnets once a year.
  3. The brush spontaneously turns off. Cause: Bad battery contact or malfunction of the control board. Prevention: Periodically clean the contacts of the battery with alcohol.
  4. Cause: Wearing of engine bearings or getting debris into the gearbox. Prevention: Lubricate the bearings with silicone lubrication once every 1-2 years.
  5. The battery doesn't charge. Cause: The battery or the charging controller fails. Prevention: Don't leave your brush charging for more than 8 hours, use the original adapter.

If your brush is in this statistic, do not rush to carry it to the service. Most breakdowns are repaired by yourself with spare parts. For example, the gear gear gear gear gear gear gear gear gear gear gear gear gear for Xiaomi T100 costs about 500-700 rubles, and its replacement takes no more than 20 minutes.

FAQ: Answers to Frequent Questions About Xiaomi T100 Disassembly

Can I remove a brush without special tools?
Theoretically, yes, but the risk of damage to the case or latches increases significantly. For example, instead of a plastic mediator, you can use an old bank card, but it is less flexible and can leave scratches. The screws can be unscrewed with a knife, but this can cause a slime to break. If you do not have tools, you better buy an inexpensive phone repair kit (costs from 300 rubles).
The brush works after assembly, but it warms up a lot.
Overheating is usually associated with poor bearing lubrication or engine contamination. Disassemble the brush again and: Blow the engine with compressed air. Apply 1-2 drops of silicone lubrication to the bearings (don't use WD-40!). Check if the rotor is touching the body (this also causes heating). If the problem remains, the circuit board's rev controller may be faulty, in which case a replacement fee will be required.
Where to buy spare parts for Xiaomi T100?
Original spare parts can be ordered: πŸ›’ On AliExpress (art search. XMT-BRUSH-100, XMT-FILTER-100 etc.). πŸ›’ In Russian stores like Beru!, Yandex Market or Wildberries (look for the model brushes). πŸ›’ In Xiaomi service centers (but there are prices higher than those of Chinese sellers). Average prices for spare parts (2026): Brush unit - 600-900 rubles. HEPA β€” 200-400 rubles Battery - 800-1200 rubles Reductor - 500-700 rubles.
How often should I clean the brush from the inside?
Cleaning frequency depends on the intensity of use: 🏠 Home use (1–2 times a week) – cleaning once every 6 months is enough. πŸš— Car or furniture (daily use) – clean every 3 months. πŸ• Animal hair removal -- you need to clean and lubricate every 1-2 months -- Signs that you need to clean your brush: Less suction power, bad smell (organic dust builds up), louder brushing.
Can I wash the brush block with water?
No! Water will damage the magnetic drum and can cause metal parts to corrosion. Clean: Remove the block from the brush. Remove the pile and debris with a dry brush or vacuum cleaner. Wipe the plastic parts with a wet (not wet!) wipe. Dry the block in air for 1-2 hours before installation. You can use alcohol wipes to disinfect, but do not spray the alcohol directly onto the block.
