How to remove a brush from a robot vacuum cleaner Xiaomi Vacuum Mop: instructions with photos and nuances

Xiaomi Vacuum Mop Robots (including models) S5/S6/Pro/P/E10/E12 And others require regular maintenance, and replacing or cleaning brushes becomes one of the most common procedures, but many users are faced with the problem of how to remove a brush without breaking the mounts and damaging the mechanism. Official instructions are often silent about the nuances, and incorrect actions can lead to failure of sensors or the engine.

In this article, we will discuss the step-by-step process of dismantling both the main rotating brush and the side brushes (in models where they are), take into account the features of different generations of Xiaomi Vacuum Mop, and warn against typical errors. You will also learn how often you need to clean your brushes, what tools you may need, and what to do if the mounting is “sour” from dust.

If you've never taken a robot vacuum cleaner apart or you're afraid of breaking something, don't worry. It's easier than it sounds if you know a few secrets. For example, post-2021 models like the Xiaomi Vacuum Mop 2 Pro use a quick-clamping brush mount that doesn't require a screwdriver, unlike older versions with screw-mounted locks.

Preparing for the removal of the brush: what to do before dismantling

Before you start removing your brush, follow a few mandatory steps, which will save you from unpleasant surprises and simplify the process:

• 🔌 Turn off the robot vacuum cleaner from the socket or remove the battery (if the model allows). Even when switched off, some components can be energized.
• 🧹 Clean the case of dust and debris, especially around the brush, this will prevent dirt from entering the mechanism during dismantling.
• 📸 Take a picture of the initial position of the brush and mounts, which will help to properly collect everything back if you are first engaged in maintenance.
• 🔧 Prepare tools: screwdriver with a cross tip (for old models), tweezers, napkins, alcohol for cleaning contacts.

Pay special attention to the type of brush installed in your model. Xiaomi Vacuum Mop has:

• 🌀 The main rotating brush (with bristles and rubber blades) - is attached to the axis with a retainer.
• 🔄 Side brushes (in models with sweep function) - are kept on plastic latches.
• 🧽 Mop nozzle (for wet cleaning) - removed differently than a dry brush.

If your robot vacuum cleaner doesn't turn on after brushing, chances are the problem isn't with the brush itself, but with the lock sensor, and we'll talk about that in the typical bug section.

Removal of the main brush: step-by-step instructions for all models

The main brush in Xiaomi Vacuum Mop is mounted on a special holder, which is fixed either by a latch (new models) or a screw (old versions).

Models 2021 and newer (fast-clamp mount)

In the robot vacuum cleaners Xiaomi Vacuum Mop 2 Pro, E12 and similar systems are used quick-release system, which allows you to remove the brush without tools:

1. Turn the robot vacuum cleaner upside down and find the brush holder.
2. On both sides of the brush are plastic latches (usually orange or red) press them simultaneously inward (to the center of the brush).
3. Pull the brush over yourself - it should easily come out of the grooves.
4. If the brush doesn't lend itself, check if the slots are full of garbage.

Models until 2021 (screw mounting)

In older versions (for example, Xiaomi Vacuum Mop) S5/S6) The brush is fixed by a screw to the cross screwdriver, so it's important not to overstretch the mount when you reassemble it:

1. Turn the robot over and find the screw in the center of the brush holder.
2. Carefully twist it counterclockwise. Don't put too much effort into it -- it's plastic.
3. After removing the screw, pull the brush upwards and onto yourself. It may sit tight because of the rubber seals.
4. If the brush is not removed, check whether the fixing pin is left inside (sometimes it falls out when the screw is twisted).

After removing the brush, examine the rotational axis for wear. If it is deformed or has a backlash, this may indicate wear of the bearings, in which case the entire brush module will need to be replaced.

💡

If the screw is "stiff" and does not twist, drop a few drops on it. WD-40 Or alcohol. 5-10 Just a minute and try again. Don't use force, it can break the attachment!

Removal of side brushes (for models with sweep function)

Side brushes are not available in all Xiaomi Vacuum Mop models, but if they are provided (for example, in the Xiaomi Vacuum Mop Pro), their dismantling is even easier than the main brush.

The side brushes are attached to plastic axles with latches, to remove them:

1. Find a small recess on the robot body next to the base of the brush (usually marked with an arrow or dot).
2. Insert a thin object (for example, a paper clip or tweezers) into this recess and lightly press down.
3. At the same time pull the brush on yourself - it should jump out of the groove.
4. Repeat the procedure for the second brush (if any).

Note that some models have different bristles lengths (one shorter, one longer) and remember or mark which one was standing so as not to confuse the installation.

⚠️ Warning: Don't pull side brushes just "forcefully" - this can break the plastic lock inside the case. Always use the opening to unlock!

Cleaning and Replacement of Brushes: When It Is Needed

The brushes in Xiaomi Vacuum Mop are consumables that require regular maintenance, and here are signs that it’s time to clean or change them:

To clean the brush, use:

• 🧼 Warm water with soap – to remove fat and dust.
• ✂️ Scissors or tweezers – to remove coiled hair.
• 🧴 Alcohol or wet wipes - for degreasing the axis.
• 🔥 Fen (cold mode) - to dry after washing.

Never use abrasives or metal brushes - they will damage plastic and rubber, and avoid hot water, which can deform bristles.

Common mistakes when removing a brush and how to avoid them

Even experienced users sometimes make mistakes that lead to breakdowns, and here are the most common ones and ways to prevent them:

1. Too much effort when removing can break plastic latches or axles. Always check first if there are additional latches.
2. Loss of screw or pin – if you unscrew the mount, immediately put the parts in a safe place (for example, in a bag with a fastener).
3. Incorrectly placing the brush back -- if the brush is crooked, it will cause vibrations and engine wear. Always check for symmetry.
4. Ignoring errors after assembly – if the robot beeps or shows error 02 (brush blocked), then something is assembled incorrectly.

If after removing the brush you notice that the axis of rotation luftites or emits creaking, this may indicate:

• 🔧 Wearing of bearings – the entire brush module needs to be replaced.
• 💧 Moisture intake (if the robot is used for wet cleaning) - you need to dry and lubricate the axis.
• 🧲 Metal particles hit – clean magnetic sensors.

⚠️ Note: If after cleaning the brush, the robot vacuum cleaner Xiaomi Vacuum Mop issues an error 02 ("Brush is blocked"), check: - Is the brush installed correctly (should be heard clicking locks). - Are there any foreign objects in the grooves of the holder. - Are the rotation sensors contaminated (wipe them with alcohol).

Replacing a brush with a new one: how to choose and install

If the brush is worn out and cannot be rebuilt, it should be replaced.

• 🆔 Compatible with the model – brushes for Xiaomi Vacuum Mop S5 Not suitable for the Mop 2 Pro due to different mounting.
• 🔄 Type of bristles - for carpets you need hard bristles, for laminate - soft with rubber blades.
• 📏 Size - Standard length of the main brush 25-30 See, but in compact models may be less.
• 🛡️ Material quality – cheap brushes break quickly and scratch the floor.

The original Xiaomi brushes have articles:

• ZNMS13WM — model S5/S6.
• ZNMS16WM — foreground Pro/P E10.
• ZNMS18WM — foreground 2/2 Pro.

Installation of the new brush takes place in reverse order:

1. Put the brush in the grooves to the end.
2. For models with latches: press the locks before clicking.
3. For models with a screw: twist the mount without excessive effort (up to light resistance).
4. Check the rotation of the brush manually - it should be smooth, without jamming.

💡

When buying a brush, check not only the model of the robot vacuum cleaner, but also the revision (for example, the Xiaomi Vacuum Mop Pro 2020 and 2022 may have different mounts).

Post-replacement maintenance: calibration and testing

After installing the new brush, the Xiaomi Vacuum Mop robot vacuum cleaner may require calibration.

• 📊 Correct operation of rotation sensors.
• 🎛️ Optimizing the speed of rotation under the new weight of the brush.
• 🚨 Preventing false errors (e.g., 02).

For calibration:

1. Turn on the robot vacuum cleaner.
2. Turn it over and manually spin the brush back and forth. 5-6 once.
3. Start cleaning in test mode (for example, around the perimeter of the room).
4. If the robot gives an error, turn it off, remove it and re-install the brush.

Also after replacing the brush is recommended:

• 🧹 Conduct a test cleaning on a small area with different types of coating (carpet, laminate, tiles).
• 🔊 Listen to the robot for extraneous noise (screaking, knocking).
• 📱 Update firmware through the Mi Home app – sometimes brush errors are fixed software.
