Xiaomi vacuum cleaner replacement: instructions for all models (2026)

Why it is important to change your brush on time

The brush is the heart of Xiaomi's robot vacuum cleaner, which not only affects the quality of the cleaning, but also the life of the engine, battery, and even the electronics of the device, and a worn brush not only collects dust worse, but also overloads the engine, forcing it to run at power limits. This leads to overheating, accelerated battery discharge and risk of breakdown, such as in Mi Robot Vacuum-Mop 2 Pro or Dreame models. D9 A clogged brush can cause an Error 10 (wheel lock) or Error 12 (engine overload) error).

The manufacturer recommends checking the condition of the brush every 3-6 months (depending on the intensity of use).However, in the realities of Russian apartments with their abundant carpet pile, pet hair and construction dust, this period is often reduced to 2-3 months. If the vacuum cleaner begins to buzz louder than usual, collects garbage at the edges worse or leaves behind a “path” of dust – this is a sure sign that it is time to clean or change the brush.

In this article you will find:

• 🔧 Step-by-step instructions for all popular Xiaomi models (including Mi Home, Dreame, Deebot).
• 🛒 How to choose the original brush and not run into a fake (from the comparison photo).
• ⚠️ Common errors that cause the vacuum cleaner to break after replacement.
• 📹 Video guides and 3D-Disassembly schemes (for visuals).

Despite the apparent simplicity of the procedure, in 30% of cases, users damage the brush mounts or break the sensor wires due to improper disassembly (Xiaomi service centers data for 2023). To avoid this, follow our recommendations - they are based on official manuals and the experience of the masters.

What brushes are in vacuum cleaners Xiaomi

Xiaomi vacuum cleaners come with three main brush types, each requiring a different approach to replacement:

1. The main rotating brush is responsible for collecting garbage at the edges and corners, it's shaped like a spiral or a nylon/silicone tree: 🌀 Mi Robot Vacuum 1S/2/2 Pro - brush with hard nylon villi. 🌀 Dreame D9/F9 — nylon + silicone blades). 🌀 Deebot T8/T9 — double-brush.

Wet cleaning brush

The most common problem is the wear of the side brush, and its villi eventually become bald, lose their elasticity, and begin to smear the dust instead of sweeping, and the turbobrush is less common, but it is more difficult to replace it, requiring a complete disassembly of the bottom panel of the vacuum cleaner.

⚠️ Note: Xiaomi Mi Robot Vacuum-Mop 2 Lite and Dreame D10 Plus, the sidebrush has a magnetic attachment. If you hear a click when you replace it, that's okay, but if the brush isn't fixed, check the integrity of the magnets in the socket.

Preparing for replacement: tools and safety

Before you start replacing, make sure you have everything you need. For most Xiaomi models, a minimum set is enough:

• 🔧 Cross screwdriver (usually) PH0 or PH1).
• 🧲 Tweezers – to extract small parts (for example, locking rings in a turbobrush).
• 📸 Smartphone – to photograph the location of wires and mounts before disassembly.
• 🧴 Alcohol wipes - to clean the contacts of sensors.
• 🔋 Spare brush (original or certified analogue).

⚠️ Warning: Never disassemble a vacuum cleaner if it was turned on less than 10 minutes ago. The capacitors in the power supply can hold a charge of up to 300 V, which is life-threatening.

Also prepare the workplace:

• 🪑 Place soft cloth (towel, fleece) on the table so as not to scratch the body of the vacuum cleaner.
• 💡 Use a bright lamp – many mounts and latches are poorly visible in low light.
• 📦 Fold the screws into separate packages with signatures (for example, “bottom panel”, “brush”), so as not to confuse them when assembling.

Disconnect the vacuum cleaner from the mains and remove the battery (if possible)

Step-by-step: Replacement of the side brush

The easiest way to change a sidebrush is to not have to disassemble a vacuum cleaner, and let's look at the process in popular models.

For Xiaomi Mi Robot Vacuum 1S/2/2 Pro

1. Turn the vacuum cleaner upwards and find a side brush (usually on the right).

2. Press the lock (the little button at the base of the brush) and pull the brush over you. It should come out effortlessly.

3. Clean the nest of dust and pile with a toothpick or compressed air.

4. Set a new brush by aligning the groove on the base with the guide in the nest. Press until you click.

For Dreame. D9/F9/D10

In these models, the brush is attached to a magnetic holder:

1. Take the base of the brush and pull it sideways (left or right, it doesn't matter), the magnet will weaken, and the brush will be removed.

2. Check the magnet contacts for rust. If you have any, wipe them with an alcohol napkin.

3. Set the new brush, press it against the magnet before you click. Make sure it rotates freely.

For Deebot. T8/T9/T10

Here, the brush is fixed by a latch on the side:

1.Push the plastic latch (usually red or orange) and pull the brush up.

2. Notice the spring mechanism, it has to stay in the nest. If the spring falls out, carefully insert it back in.

3. The new brush is mounted at an angle of 45.°, then twists to fixation.

💡 If the new brush doesn't rotate or it touches the body, check the polarity of the magnets (for Dreame models) and sometimes they are attracted by the wrong side that blocks the rotation.

Replacement of the central turbobrush: disassembly of the vacuum cleaner

The turbobrush is located under the bottom panel of the vacuum cleaner, so replacing it requires partial disassembly, which is more complicated, but if you act carefully, even a beginner can cope.

Step 1: Remove the bottom cover

1. Turn over the vacuum cleaner and unscrew all the screws on the bottom panel (usually 4-6 pieces). D9 screws can be hidden under stickers - gently put them under the knife.

2. Disconnect the sensor connectors (usually orange or red) and remember their location or take a picture.

3. Remove the lid by pulling it upwards and a little over yourself. Be careful, there may be wires glued to the body inside.

Step 2: Removing the turbobrush

1. Find the shaft of the turbobrush, which is in the middle and is secured by two plastic clips.

2.Push the clips at the same time (you can use two screwdrivers) and pull the shaft.

3. Remove the lock ring with tweezers. In some models (for example, Mi Robot Vacuum-Mop P) instead of the ring, a screw is used - unscrew it.

Step 3: Install a new brush

1. Put a new brush on the shaft, aligning the grooves.

2. Secure it with a locking ring or screw.

3. Set the shaft back into the grooves and snap the clips.

⚠️ Note: In models with a speed sensor (for example, Dreame) F9) After you replace the brush, you may need to calibrate:

1. Turn on the vacuum cleaner.
2. Press the Spot Cleaning and Home buttons for 5 seconds.
3. Wait for the sound signal (2 short squeaks).

1. Correct installation of the locking ring (it should sit in the groove without backlash).

2. Absence of foreign objects in the mechanism (hair, thread).

3. Shaft coaxiality - it must rotate without beating.-->

How to choose the original brush and not run into a fake

Xiaomi’s vacuum cleaner parts market is flooded with fakes that are seemingly indistinguishable from the originals, but serve 2-3 times less.

Signs of the original brush

• 🏷️ The package must be made of dense cardboard with a hologram Xiaomi or Dreame. QR-check-in.
• 🔍 Villi -- the original has uniform lengths, no barbs. Counterfeiting often has irregular cuts.
• 🧲 The magnet (for Dreame models) must be pulled with force.
• 📏 Dimensions -- measure the diameter of the shaft with a rod. For example, for the Mi Robot 2 Pro, it should be exactly 6 mm.

Where to buy

💡 Tip: Before buying, check compatibility by the vacuum cleaner model, not just the appearance of the brush. 1S Not suitable for Dreame D9, visually similar.

💡

The most reliable way to avoid counterfeiting is to buy brushes labeled “Original Xiaomi Part” and check the serial number on the manufacturer’s website.

Frequent Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes when replacing a brush that leads to breakages.

• ⚡ Undisconnected battery -- if you forget to take out the battery, a short circuit in disassembly can burn the control board!
• 🔧 Twisted screws -- plastic threads in the vacuum cleaner body easily break. Tighten the screws without effort until first resistance.
• 🧲 Improper magnet polarity (in Dreame) – if the brush is pulled by the wrong side, it will cling to the body as it rotates.
• 📱 Resetting after replacement – in some models (e.g. Deebot) T9) Replace the brush resets the sensor calibration. After assembly, run the cleaning test cycle.
• 🧹 Ignoring cleaning the nest – if you do not remove the pile and dust from the grooves, the new brush will rotate with difficulty.

⚠️ Warning: If the vacuum cleaner produces an Error 5 (engine problem) or Error 9 (brush lock) error after replacing the brush, turn it off immediately and check it:

• Correct installation of the locking ring on the turbobrush.
• Absence of foreign objects in the mechanism.
• Integrity of the speed sensor wires (they can be disconnected during disassembly).

If the error persists, return the old brush and check if the vacuum cleaner works with it, and if so, the problem is with the new brush (possibly unoriginal or defective).

Caring for a brush: how to extend its service life

Replacing a brush is a last resort, and if you care for it properly, it will last 1.5 to 2 times longer.

Weekly service

• 🧼 Pile cleaning – remove the wound hair and threads after each cleaning. use scissors or a special cleaning hook (comes complete with some models).
• 💦 Washing – the side brush can be washed with warm water and soap (do not use aggressive detergents.
• 🌬️ Purge – once a month, clean the brush slots with compressed air (for example, a canister for the keyboard).

What is absolutely not to be done

• 🔥 Dry the brush with a hair dryer - high temperatures deform plastic and pile.
• ⚗️ Use solvents (acetone, gasoline) - they destroy nylon villi.
• 🪛 Cut the pile with scissors - this disrupts the balance of the brush and leads to vibrations.

💡 Useful Lifehack: To keep the pile of the sidebrush firmer for longer, treat it once a month with silicone lubricant (sold in auto parts stores). Put a few drops on the napkin and wipe the villi. This will prevent them from brittle.
