A stuck brush in Xiaomi's robot vacuum cleaner is a problem that one in five owners face: Hair, thread or debris block rotation, and attempts to pull the brush by force often end in mounts breaking or wires breaking. In this article, we will analyze safe extraction methods for all popular models: from the budget Mi Robot Vacuum-Mop to the flagship DreameBot and Viomi. V3.
The main mistake users make is to ignore design features, such as in models with automatic brush lifting (for example, Xiaomi Mi Robot Vacuum-Mop 2 Pro), forced pulling can damage the servo drive, and in robots with side brushes on magnetic mounts (like Dreame). F9) We'll show you how to avoid these problems and keep the warranty.
In the article you will find:
- π§ Step-by-step instructions for 5+ Xiaomi models (with photos and videos)
- π οΈ List of tools that will help (and what you canβt use)
- β‘ Typical causes of jamming and how to prevent them
- π What to do if the brush is not removed even after the analysis
1.Preparation: What to do before removing the brush
Before you take up the brush, disconnect the robot from power - even when switched off, some models (for example, Viomi) V2 Pro) keep the voltage on the motor contacts. If the vacuum cleaner was on charge, wait 10-15 minutes: the capacitors could accumulate charge.
Next, look at the body for visible damage. Cracks near the brush compartment or traces of melting plastic indicate mechanical blockage (for example, hitting a metal object), in which case do not try to pull the brush out by force - first make sure that there are no foreign objects inside.

If your brush is stuck during cleaning, check:
- π§΅ Wrapped hair/threads - most often block the shaft of the motor. Try to gently tweez them with tweezers.
- πͺ¨ Foreign objects β coins, paper clips or stones can get stuck between the brush and the body.
- π Discharged battery - some models (Dreame) D9) lock the brush at low charge.
β οΈ Warning: Don't use a knife or scissors to lick a brush - it will damage sealing gums. S10+ and newer rubber bands are responsible for the tightness of the dust collector.
2. disassembly of the body: how to get to the mechanism of the brush
Most Xiaomi robot vacuum cleaners have a brush attached to the bottom cover, which is removed after spinning 4-6 screws.
- π© Models to 2020 (Mi Robot) 1S, Viomi V1): screws under the cross screwdriver, the lid is removed easily.
- π§ Models 2021-2023 (Dreame) W10, Mi Robot Vacuum-Mop 2 Lite: Torx screws T8 or Tri-wing, the latch cover.
- π οΈ Flagships of 2026 (DreameBot) X30 Ultra: screws hidden under plugs, require plastic mediator to disconnect latches.
When you take the lid off, you'll see the brush mechanism, and in most cases, it's attached to the shaft of the motor by:
| Type of attachment | Models. | How to take it off |
|---|---|---|
| Schlitz connection | Mi Robot 1C, Viomi V2 | Pull up with a slight sway |
| Bayonette castle | Dreame D9, Mi Robot Vacuum-Mop P | Turn counterclockwise at 15.Β° and pull |
| magnetic fixator | Dreame F9, Viomi SE | Put a screwdriver on the side (do not make an effort!) |
| Screw anchorage | DreameBot L10, Xiaomi S10 | Unscrew the Torx screw T6 middle-shaft |
If the brush doesn't lend itself, don't pull it -- first check if the shaft is blocking debris in the bearing. In Xiaomi models with Smart Dust Collection (such as Mi Robot Vacuum-Mop 2 Pro), dust can accumulate under the brush, forming a dense lump.
3. Step-by-step instructions for popular models
Each Xiaomi series of robot vacuum cleaners has unique design features, and below are detailed instructions for the most common models.
Xiaomi Mi Robot Vacuum-Mop 2 Pro / 2 Lite
1.Flip the robot and unscrew the 4 Torx screws T8 bottom-cover.
2. Carefully tuck the lid with a plastic card - it is held on 2 latches in the front.
3. The brush is attached with a bayonet lock: turn it counterclockwise before clicking, then pull it up.
4 If the brush does not turn, check whether the plastic locker (white) blocks it from the side.
Dreame D9 / D10
1. Remove the side brushes (they are on magnets) and the dust collector.
2. Unscrew 5 Tri-wing screws around the perimeter of the bottom cover.
3. Under the lid, you'll see a motor brush with a red lock -- press it with a screwdriver and pull the brush over you.
4. If the lock breaks, the brush can be removed by removing the belt of the drive (gently move it from the shaft of the motor).
Viomi V3 / SE
1. These models have a dual fixation system: the brush is held on both the bayonet and the magnet.
2. After removing the cover, turn the brush to 20.Β° left, then pull up with force. ~1 kg.
3. If the brush does not come out, check if the position sensor has jammed (a small black detail next to the shaft).

If the brush "stick" to the shaft due to overheating, spray the connection site. WD-40 And wait 5 minutes. Don't use oils, they'll attract dust.
4 What to do if the brush is not removed
If the brush remains in place after all the manipulations, the problem may be in one of three nodes:
- Jammed bearing - more common in models with a metal shaft (DreameBot) X30). Try to scroll the brush with your hands: if it does not rotate, the bearing requires replacement.
- Drive cable break: In electronically lifted robots (Mi Robot Vacuum-Mop 2 Pro), the cable can break, blocking the mechanism, Sign: the brush does not rise when the moping mode is activated.
- The deformation of the motor shaft -- if the robot fell or fell under furniture, the shaft could bend, in which case the brush will "bit" as it rotates.
For diagnosis:
- π Examine the shaft of the motor for the presence of burrs or rust (especially if the robot was operated in wet rooms).
- π Check the backbone of the brush: if it staggers more than 2 mm, the bearing is worn out.
- π Connect the robot to charging and turn on cleaning mode: if the brush motor buzzes, but does not rotate, the problem is mechanical locking.
β οΈ Note: Xiaomi models with laser sensor (LDS) If the robot is spinning in place after disassembly, start calibration through the Mi Home app. β Sensor calibration).
5 Tools that will help (and not be used)
To safely remove the brush, you will need:
| Tool. | What do you need? | The alternative |
|---|---|---|
| Plastic mediator | Separation of the latch cover | Old bank card |
| Torx screwdriver set T6βT10 | Body screws and brush shaft | Phone repair kit |
| Tweezers with curved ends | Removal of hair from bearing | Toothbrush (for cleaning) |
| Silicone lubricant | Post-extraction shaft treatment | WD-40 (clean-up!) |
It is absolutely impossible to use:
- π¨ Hammer or pliers - this deforms the shaft and body.
- π₯ Heating with a hair dryer - melt plastic fixers.
- π§² Magnets β can damage Hall sensors in the engine.
- π§ Water or alcohol β corrosion of contacts guaranteed.

6.Prevention: How to avoid jamming the brush in the future
To prevent the brush from getting stuck, follow these rules:
- π§Ή Clean your brush after each cleaning β use hair removal scissors and vacuum cleaner to blow dust out of the bearing.
- π« Don't remove long-tail carpets, the threads cling to the brush and wind onto the shaft. Turn on vacuum cleaner only (without brush) for these coatings.
- π Change your brush every 6-12 months β worn bristles increase the load on the engine.
- π§ Dry the robot after wet cleaning - moisture oxidizes the shaft and retainers.
In models with a self-cleaning station (DreameBot) X30 Ultra is automatically washed, but even there you need to manually clean once a month. Pay attention to the state of the drive belt, if it stretches, the brush will slip and wear out faster.
π‘
Regular brushing extends the life of the robot vacuum cleaner motor by 2-3 times, and 80 percent of jammings are caused by hair and thread, not mechanical breakdowns.
7. Frequent mistakes and how to avoid them
Even experienced users make mistakes when removing a brush.
- π Energized disassembly β in Viomi models, capacitors can hold a charge for up to 30 minutes. Always wait 15 minutes after switching off.
- π© Loss of screws in Dreame D9 Take a picture of their position before disassembling.
- π§² Using force on magnetic fixtures breaks the attachments. Use a plastic transmitter.
- π§ Replacing the brush with an unoriginal one - cheap analogues may not fit in weight, which leads to vibrations and breakage of the bearing.
If after removing the brush, the robot gives an error E05 (a malfunction of the brush motor), try:
- Reboot the robot (hold the power button for 10 seconds).
- Check the connection of the motor connector (can depart during disassembly).
- Update your firmware through the Mi Home app β sometimes an error is caused by a software failure.
