How to remove the side brush from the robot vacuum cleaner Xiaomi: instructions for all models

Why remove the side brush and when it is necessary

Xiaomi’s robot vacuum cleaner side brushes are one of the most vulnerable design elements, collecting debris along walls, furniture and corners, but quickly wear out due to constant contact with obstacles.

First, to clean the hair, threads and wool. Even if you regularly clean the main container, the side brushes are often left unattended until they start creaking or slowing down the rotation. Second, to replace them with a new one, the manufacturer recommends updating them every 6-12 months depending on the intensity of use. Finally, dismantling may be necessary in the diagnosis of malfunctions, for example, if the robot has stopped snuggling against the walls or one of the brushes rotates.

It is important to understand that the design of brush attachment varies depending on the model. For example, Xiaomi Mi Robot Vacuum-Mop 2 Lite uses a plastic latch fixer, and Dreame D9 uses a metal axis with threads. Incorrect removal can lead to a break in the attachment or damage to the vacuum cleaner body. Next, we will discuss the universal methods suitable for most of the brand’s devices, as well as nuances for specific lines.

Preparation for dismantling: tools and security measures

Before you start removing the side brush, make sure the robot vacuum cleaner is off and off the charging station, which will prevent accidental switching on during work.

• ✅ Flat screwdriver (for models with screw fasteners)
• ✅ Tweezers or thin pliers (to remove latches)
• ✅ Wraps or cloth (to clean the dirt around the axis)
• ✅ Silicone-based lubricant (optional, for axis processing)

If the brush is heavily contaminated, it is recommended to pre-rinse it under warm water with soap and dry. Never use aggressive chemical solvents (acetone, gasoline) - they can damage plastic parts and rubber seals. For models with automatic lifting of brushes (for example, Xiaomi S10+) before dismantling, make sure that the mechanism is in the lower position - otherwise the mount may jam.

⚠️ Attention: Do not put excessive effort in removing the brush. If the mounting does not lend itself, check whether the accumulated debris or the deformed axis blocks it.

Universal way to remove the side brush (for most models)

Most Xiaomi robot vacuum cleaners are equipped with quick-removable side brushes. To remove it, follow the following steps:

1. Turn the vacuum cleaner upwards, placing it on a flat surface (for example, a table). Avoid soft coatings so as not to scratch the sensors.
2. Find a plastic fixture on the axis of the brush, which is usually located on the inside (closer to the body) and has a small protrusion for the finger.
3. Press the lock to the body and simultaneously pull the brush over you. It should come out of the slots without effort.

If the lock is not pressed or the brush is not moving, check if there is any accumulated dirt inside the axis. Sometimes hair or dust blocks the mechanism, in which case, gently clean the hole with tweezers or compressed air.

For threaded models (such as some versions of the Viomi) you will need to unscrew the brush counterclockwise. Use a flat screwdriver or coin to turn a plastic nut. Don't put too much effort into it - the threads can be plastic and easily break.

Features of removing brushes on popular models

Despite the general principles, some Xiaomi robot vacuum cleaners have unique mounting designs. Below is a table with features for popular lines:

For the metal-axis Dreame models, it is useful to apply a few drops of silicone lubricant to the thread before unscrewing, which will make it easier and prevent damage. If the brush still does not respond, try clamping the vacuum cleaner body between your knees and unscrewing with both hands.

⚠️ Attention: In the robot vacuum cleaners Xiaomi S10+ and S11 side brushes are integrated into the lifting mechanism. If you remove them for replacement, make sure that the new brushes are compatible with this system - universal counterparts may not be suitable.

Cleaning and maintenance of the side brush: extending the service life

Once you remove a brush, don't just replace it. Regular cleaning and lubrication can significantly extend the life of both the brush and the attachment mechanism.

• 🧹 Hair and thread removal. Use scissors or tweezers to cut the coiled hair at the base of the bristles. Don't pull them - this can damage the roots of the bristles.
• 💧 Wash. Soak the brush in warm soapy water for 10 to 15 minutes, then rinse under a stream of water. Avoid hot water - it can warp the plastic.
• 🛠️ Axis lubricant. After drying, apply 1-2 drops of silicone lubricant to the metal or plastic axis. This will reduce friction and prevent creaking.
• 🔍 If the bristles are more than 50% gone or have lost their elasticity, it's better to replace the brush, it will no longer collect garbage efficiently.

For models with rubber tips on bristles (for example, Dreame D10 Plus), avoid long soaking - the rubber is enough to wipe with a wet wipe. Also do not use abrasive detergents that can damage the coating.

💡

If the brush is still hard to rotate after cleaning, check if the axis has not deformed. In some cases, it can be straightened with pliers, but if the bending is strong, it is better to replace the whole brush.

Typical errors in removing and installing a brush

Even experienced users sometimes make mistakes that lead to breakages or deterioration of the vacuum cleaner, the most common of which are:

1. The force is not in the right direction, like trying to unscrew the Mi Robot Vacuum-Mop 2 counterclockwise, even though it has a latch. It can break the lock.
2. Ignoring debris in the axis. If you don't clean the hole before you install the new brush, it can rotate unevenly or jam.
3. Incorrect installation. The brush must enter the slots before the characteristic click. If the lock does not snap, it will fall out during cleaning.
4. Use of non-original brushes: Cheap analogues can have a different axis diameter or bristle length, which will lead to imbalance.

Another common problem is tug-of-twisting the thread mount when installed, and this is especially true for Dreame models where the metal axis is used. Excessive force can lead to the strain of the thread and the inability to remove the brush in the future.

⚠️ Warning: After replacing your brush, always check it manually before running the vacuum cleaner automatically. Turn on the robot and manually press it against the wall - the brush should rotate smoothly, without jerking or extraneous sounds.

When it’s time to change the side brush: signs of wear

Side brushes are consumables and need to be replaced periodically, and here are key signs that it’s time to upgrade:

• 🔄 Uneven rotation. The brush scrolls in jerks or stops during cleaning.
• 🧵 Constant hair wounding, if hair accumulates around the axis more often than usual, it indicates the wear of the bristles.
• 🔊 Extraneous sounds: Screaming, knocking or rustling while working - a sign of deformation of the axis or bristles.
• 📏 Visible wear. The bristles have become shorter by 30 percent or more or have lost their elasticity.
• 🚫 Decreased cleaning efficiency: Robot picks up garbage worse along walls, leaves dust lanes.

The manufacturer recommends that brushes be changed every 6-12 months, but the actual duration depends on the intensity of use. For example, in homes with animals or long-haired residents, brushes wear out 2-3 times faster. To check the condition, it is enough to visually compare a new and old brush - the difference in the length of the bristles will be obvious.

💡

Regular replacement of side brushes not only improves the quality of cleaning, but also reduces the load on the robot vacuum cleaner engine, prolonging the life of the device as a whole.

Where to buy spare parts and how to choose a compatible brush

The original side brushes for Xiaomi robot vacuum cleaners can be purchased in several places:

• 🛒 Official Xiaomi Store.Guaranteed original parts, but the price may be higher than that of third-party sellers.
• 🌍 AliExpress, Amazon, eBay. Wide selection of analogues and originals, but check seller's rating and reviews.
• 🏬 Local appliance stores. Sometimes there are generic brushes that are suitable for several models.
• 🔧 Service centers, you can order parts through authorized workshops.

When choosing a brush, pay attention to the following parameters:

1. A robot vacuum cleaner model. Even within a single ruler (like the Mi Robot) there can be differences in mountings.
2. The bristles are too short, the bristles are worse at collecting garbage in the corners, the bristles are too long, they wind their hair faster.
3. Axis material: Plastic axles are cheaper, but less durable than metal axles.
4. There are rubber tips, which reduce noise and protect furniture from scratches.

Original brushes typically cost 300-800 rubles per pair, depending on the model. Analogs can be cheaper, but their quality is often worse - bristles are more quickly tracked and plastic breaks when installed. If you buy a non-original brush, look for options marked "100% compatible" and verified reviews.
