The Xiaomi Mi Robot Vacuum series of robotic vacuum cleaners have proven to be reliable cleaners, but even the most advanced technology requires regular maintenance. Xiaomi C1 is no exception: over time, the pile of the side brush wears off, and plastic blades can crack from hitting hard objects. Owners often face the need to quickly replace this consumable to avoid reducing the efficiency of cleaning or the appearance of extraneous noise.
The dismantling process seems trivial, but careless actions can damage the landing site or the drive engine itself. In this article, we will discuss in detail how to remove the side brush from the Xiaomi C1 robot vacuum cleaner safely and quickly. You will learn about the intricacies of the mounting design and understand the nuances worth paying special attention to when maintaining.
Regularly checking the condition of the side blades is not just a recommendation, but a necessity to extend the life of the entire device. A hair-filled axle or broken blade creates an imbalance that increases the load on the motor, which is why it is important to know the correct algorithm of actions so that the replacement goes smoothly and does not require the call of a service engineer.
Diagnosis of the condition of the side cleaning unit
Before you start physical intervention, you need to conduct a visual inspection of the current state of the site. Often users rush to replace the part, although the problem may be in the banal contamination. Carefully examine the side brush for wound hair, thread or fur of pets that may have blocked the rotation.
Look at the plastic blades: if you notice chipped, cracked, or severely worn pile to the base, a replacement is necessary. Ignoring these signs causes the Xiaomi C1 robot to stop sweeping debris from corners and along the walls, leaving dirty stripes. In addition, the deformed brush can scratch the floor or beat against the body, emitting an unpleasant crack.
⚠️ Warning: If the brush makes a loud squeak or screech when working, immediately stop cleaning. Continuing to operate in this mode can cause the drive motor to burn out, the replacement of which costs much more than a new brush.
It's also worth checking the central hub where the engine shaft is inserted, and if the plastic around the hole is crumbled or has traces of melting, simply replacing the brush won't help, it'll require more deep repairs. In normal condition, the sleeve should be intact, without backlashes or gaps.
Tools and workplace preparation required
One of the main features of Xiaomi's robot design is minimal maintenance. You don't need any sophisticated tools to perform the replacement procedure. In most cases, your hands are enough and perhaps a simple tweezer to remove debris from the pallet.
Prepare a flat surface with good lighting, it could be a table or a floor covered with clean cloth, it's important that there are no small objects on the surface that could accidentally get inside the body of the robot when you flip, and it's also recommended to have a dry soft cloth on hand to wipe the freed surfaces.
A list of what you may need in the process:
- 🧹 New side brush compatible with Xiaomi Robot Vacuum C1 (original).
- 🧷 Tweezers or a thin spoke (to clean the axis of hair).
- 🧼 Dry rag or microfiber napkin.
- ✂️ Small scissors (in case you have to cut tightly wound threads).
Do not use aggressive chemicals or water directly in the removal process unless urgently needed.Moisture entering the engine compartment may cause contacts to corrosion or short circuit the next time you turn on.
💡
Buy side brushes immediately with a set of 2-3 pieces. This is more profitable for the price and ensures that you always have a spare part at hand in case of sudden breakage.
Step-by-step: how to remove an old brush
The dismantling process is designed by Xiaomi engineers to be intuitive. You don't have to unscrew the screws or disassemble the entire vacuum cleaner body. All the actions are done on the bottom of the device.
Turn the Xiaomi C1 robot vacuum cleaner upside down. Make sure the device is off or in sleep mode so that random button presses don't activate the engines during the procedure. Find the side brush; it's on the right side (when viewed from above) or on the left side (when viewed from below, depending on orientation, but usually it's on the starboard side).
Follow the algorithm further:
- Take your fingers on the central plastic disk of the brush.
- Pull the part strictly upwards, perpendicular to the surface of the case.
- Apply a moderate force. The brush is held on the friction joint and the slits, so it should be removed with a characteristic click.
- If the brush does not lend itself, sway it slightly from side to side, while pulling it up.
☑️ The brush removal algorithm
Sometimes, if the brush has been in use for a long time without maintenance, it can "stook" due to compressed dust, in which case you can carefully tuck the edge of the central disk with a flat screwdriver protected by a fabric so as not to scratch the plastic, but you need to do this extremely carefully.
Cleaning of the seat and engine shaft
Once you remove the consumable, you'll see a landing place, a critical step that many people ignore, and the hole often accumulates large amounts of dust, hair and small debris that thickens over time.
In the center, you'll see the drive shaft, which is a metal or plastic pin with faces, and if you have hair wrapped around the shaft, you have to remove it, use tweezers or the tip of scissors, and clean the shaft, so that the new brush is centered properly and the load is evenly distributed.
Wipe the inside of the niche with a dry wipe, make sure there are no large debris particles left that could get into the rotational mechanism, and inspect the niche itself for cracks or deformities of the plastic.
| Element | Status of the norm | It needs attention. | Action. |
|---|---|---|---|
| shaft | Pure, sharp granules | Hair wound, oxidation | Clean with tweezers |
| Planting niche | Dry, no trash. | Dust, lumps of dirt | Wash with a napkin. |
| Fastening slats | Whole, no chipping. | Erased, damaged. | Replace the brush/repair |
| Plastic of the case | Smooth, no cracks. | Cracks around the hole | Control during installation |
If you find that the engine shaft is too easy to scroll or, conversely, jammed, this may indicate a malfunction of the engine. In normal mode, the shaft should have an easy ride, but not dangle.

Installation of a new side brush on Xiaomi C1
Installation of the new part is in the reverse order, but has its own nuances. Take a new side brush and make sure it is designed for your model. While many brushes are universal to the Xiaomi ecosystem, the shape of the mounting hole may differ.
You can combine the hole in the center of the brush with the engine shaft. You can see the shape of the slits -- they should match. You don't have to put too much effort into it. If you get the shape right, the brush will fit in easily.
Press the center of the brush until you have a characteristic click or feel like you're in a tight position. The gap between the body of the brush and the body of the robot should be minimal, but the brush should not rub against the plastic of the body when you rotate with your hand.
⚠️ Warning: Never turn on the robot vacuum cleaner if the side brush is not fully installed or skewed.This can lead to instant breakage of fasteners or damage to the motor gearbox.
Once installed, spin the brush in different directions, it should rotate freely, without jamming or extraneous sounds. If you feel resistance, remove the brush again, check the purity of the shaft and try to install again.
Typical errors and operating tips
Even a simple replacement procedure can go wrong if you make common mistakes. One of the most common problems is using incompatible brushes. Cheap copies can have a shaft too large in diameter, which puts excessive pressure on the engine bearing.
Another mistake is ignoring regular cleaning, and many users only change their brush when it falls apart, but replacing or even cleaning the hair every 2-3 months can significantly extend the life of the entire node.
Tips for long service:
- 🧶 Regularly trim long hair and thread wound on the axle, without waiting for a full replacement.
- 🚫 Avoid cleaning large pieces of cloth or ropes that can wind up on the brush and jam it.
- 🔄 Change brushes in pairs or sets to make wear uniform (if you change more than one).
Also, remember that the life of the side brush depends on the type of flooring. On carpets with high pile wear occurs faster than on laminate or tile, so owners of carpets should check the condition of the brush more often.
💡
High-quality installation and regular cleaning of the side brush is the key to the quiet operation of the robot and effective cleaning along the walls and in the corners of the room.
