How to quickly and safely clean the brush of the robot vacuum cleaner Xiaomi hair: a guide with photos and tips

Xiaomi’s robot vacuum cleaners are indispensable cleaning aids, but their main problem is getting hair and wool tangled in brushes. Even the most advanced Mi Robot Vacuum-Mop 2 Pro or DreameBot D9 models are not immune to the accumulation of debris on rollers. If you don’t clean your brushes on time, it leads to reduced cleaning efficiency, overheating of the engine and even breakage.

Why does hair cling to brushes so much? It's design: rubber and nylon villi create friction, and rotational motion literally drives hair into the mechanism. A particularly pressing problem for owners of long-haired pets or people with thick hair. In this article, proven cleaning methods that will prolong the life of your robot vacuum cleaner and keep it productive.

Why it is important to clean robot vacuum cleaners regularly

A running brush is not only a reduction in cleaning quality, but the hair wound on the axis of the roller puts additional stress on the engine.

• 🔋 Increased battery consumption – the robot spends more energy scrolling through a clogged brush, reducing the running time from a single charge.
• 🔥 Overheating of the engine - constant resistance leads to wear of bearings and can cause a malfunction in operation.
• 🚫 Blocking rotation – if the hair gets into the gears of the drive, the brush stops spinning altogether.
• 🦠 Bacteria Reproduction – Wet wool and dust create an ideal environment for mold and microbes.

Xiaomi manufacturers recommend cleaning brushes after every 3-5 cleaning, but in practice, the frequency depends on the intensity of use. For example, in a house with two cats, cleaning may be necessary after each cycle. Ignoring the problem for 2-3 months in 80% of cases leads to the need to replace the brush or even repair the drive mechanism.

What tools will be needed for cleaning

You don't need expensive tools to clean the house, and most of the tools are in every home.

⚠️ Warning: Never use metal objects (screwdrivers, knives) to clean plastic brush parts. They leave scratches that later catch even more hair. Also avoid aggressive solvents - they can damage rubber seals.

💡

If you have a self-cleaning model (such as the Xiaomi Mi Robot Vacuum-Mop 2 Ultra), still check the mechanism manually periodically - the automatic system only removes surface debris.

Step-by-step: how to remove hair from the brush

The cleaning process depends on the type of brush. Xiaomi's robot vacuum cleaners use two main types:

1. The main rotating brush (roller with villi) - located in the center, is responsible for collecting garbage from carpets.
2. Side brushes (small “blades”) sweep garbage to the main brush, are often clogged with hair.

Let’s start with the main brush – the most problematic area:

1. Remove the brush. Most models (Mi Robot Vacuum, Viomi V2) just press the locks on the sides and pull the roller on yourself. In some versions (DreameBot Z10 Pro) you will need to unscrew the screws with a cross screwdriver.
2. Remove visible hair lumps. Carefully pull at loose ends to pull out the bulk. Don't pull sharply, that's how you can tear the villi.
3. Cut the entangled hair. With sharp-ended scissors, cut the hair at the base of the brush, trying not to touch the plastic. Keep the blades parallel to the roller.
4. Clean the axle and bearings. With a pince or a toothpick, remove the hair wound onto the metal rod. This is where the most garbage accumulates!
5. Wash and dry. If the brush is heavily contaminated, rinse it under warm water with soap (do not use detergents with abrasives!). Dry thoroughly before installing the back - moisture can cause bearings to corrosion.

⚠️ Note: In electric brush models (e.g. Xiaomi Mi Robot Vacuum-Mop P), don't try to disassemble the mechanism yourself - this will void the warranty.

How to Clean Your Brush Without Removal (Emergency Method)

If the robot vacuum cleaner suddenly stopped collecting garbage normally, and there is no time to disassemble it right now, you can try cleaning the brush without completely dismantling:

1. Turn the robot over and turn it on in cleaning mode (for example, click the Spot Cleaning button on the case).
2. When you rotate your brush, gently hold the scissors and cut the visible hair lumps. Keep the blades at a 45° angle to the roller so you don't hit the villi.
3. After pruning, turn off the vacuum cleaner and manually remove the remaining hair with a toothpick.

This method is only suitable for minor contaminants. If the brush is completely wrapped in hair or not rotating, you can not do without disassembly. Also remember that working with the device on requires caution - do not touch the rotating parts with your fingers!

How to clean a brush: allowed and prohibited means

Not all detergents are equally useful for a robot vacuum cleaner, and here's what you can and can't use:

To disinfect the brush after cleaning, you can use chlorhexidine (0.05% solution) or hydrogen peroxide (3%), which kills bacteria, but does not spoil the material of the brush, just wipe the villi with a moistened napkin and let it dry for 10-15 minutes.

How to prevent rapid contamination of brushes: 7 work tips

It is impossible to completely avoid hair coiling, but you can significantly reduce the frequency of cleaning:

• 🧹 Regularly sweep floors manually — the less hair on the floor, the less it will get into the robot.
• ✂️ Shorten the pile on the carpets -- the long pile clings to the brush and pulls out along with the hair. Use a carpet trimmer.
• 🔄 Set up a cleaning schedule – frequent short cleaning (a daily 20 minutes) is more effective than one long cleaning week.
• 🚫 Eliminate areas with more hair – use virtual walls or no-go zones in the Mi Home app for the bathroom or bedroom.
• 🛁 Wash your brush after every 5th cleaning – even if it is visually clean, fat and dust accumulate on the villi.
• 🔧 Check your side brushes weekly – they clog faster than the main brush and can break when blocked.
• 🔋 Watch the battery charge - a discharged robot can "twist" on carpets, strengthening the hair winding.

If your robot vacuum cleaner supports high-power mode (for example, Max Mode in Xiaomi Mi Robot Vacuum-Mop 2 Pro), use it only on smooth surfaces. On carpets, the high speed of the brush rotation increases hair entanglement.

💡

The most effective way to extend the life of a brush is a combination of mechanical cleaning (scissors + tweezers) and preventive washing (water + alcohol) every 2 weeks.

When it’s time to change your brush: 5 signs of wear

Even with regular cleaning, the robot vacuum cleaner brush wears out over time, and here are the signals that it's time to consider replacing it:

• 🔄 The villi are stuck or broken off - the brush loses the ability to capture debris.
• 🔊 There was a creak or knock when rotating - a sign of wear bearings.
• 🌀 The brush rotates in jerks or stops - the hair could damage the drive mechanism.
• 🧹 Robot worse picks up garbage from carpets - even after cleaning, efficiency fell.
• 🚨 The app shows the error "Brush blocked" - most often means critical wear.

The service life of the brush depends on the intensity of use:

• The main brush is 12-18 months with regular cleaning.

In models with rubber rollers (for example, DreameBot L10 Pro) the service life is longer – up to 24 months, but they are worse cope with long hair.

The original brushes for Xiaomi can be bought at the official Mi Store or on AliExpress (see the code of the robot model).

• Side brush - 300-500 ₽ paired.
• Main brush - 800-1500 ₽.

Analogs from third-party manufacturers (such as Baseus or Remax) are cheaper, but may be worse at collecting garbage.
