How to remove a brush from a robot vacuum cleaner Xiaomi Mi Robot Vacuum Mop

Maintenance of an automatic cleaning assistant is not just a recommendation, but a necessity to maintain its high performance. Over time, the pile of carpets, hair and pet hair are wound on a rotating shaft, creating a dense cocoon that blocks the engine. If you notice that the Xiaomi Mi Robot Vacuum has begun to make strange sounds or sucks up dust worse, it's time for maintenance.

Many users are afraid to disassemble the equipment for fear of damaging fragile latches or breaking the warranty. However, the design of Xiaomi robot vacuum cleaners is designed so that the owner can carry out basic cleaning without using a complex tool. In this article, we will discuss in detail how to safely remove the brush, clean it and install it back, returning your gadget to factory power.

Regular cleaning prevents the engine from overheating and extends the life of the bearings. A clogged brush is the first reason a robot can stop leaving the base or start moving around the room randomly. Let's take a look at the process in detail so you don't have any doubts about the correctness of the action.

Workplace preparation and necessary tools

Before you start dismantling, you need to have a safe environment to do the work, you need a smooth, well-lit surface, preferably a table covered with clean cloth or paper, which will prevent the loss of small parts and allow you to immediately see all the debris that will fall out of the mechanism during cleaning.

To service most models, such as the Xiaomi Vacuum Mop 2 Pro or Roborock S5 Max, a special tool is usually not required.The design of the main module cover is equipped with convenient notches for fingers. However, in some cases, if the pile is compressed very strongly, you may need a small flat screwdriver or a special knife that comes with the device.

• 🔧 Screwdriver with a flat sting (in case of severe contamination or for putting the lid on).
• ✂️ Manicure scissors or bokreases for cutting coiled hair.
• 🧹 Additional dry rags for cleaning the inner cavity.
• 📱 Smartphone with Mi Home app (to check error status after assembly).

⚠️ Warning: Never start disassembling while the robot is connected to the charging station or on. be sure to flip the device over and make sure the power indicators are turned off to avoid accidental start of the motors.

Prepare the garbage container in advance. When you open the compartment, you can get dust that has not been removed by the container, and having a vacuum cleaner on hand will also be a smart solution for the final cleaning of the workplace.

Access to the main cleaning module

The first step is to gain access to the shaft itself. Turn the Xiaomi robot vacuum cleaner upside down. On the bottom panel, you'll see a large rectangular or oval lid that covers the main turbobrush. Depending on the particular model, whether it's the classic Mi Robot Vacuum or the newer Xiaomi Vacuum Mop Essential, the fixing mechanism may be slightly different.

On current models, the lid is often held by two latches on the sides. You need to press them simultaneously or alternately, after which the lid will easily recline or be removed completely. On older models, you may need to unscrew several screws, but in the Mop line, screwless design prevails for the convenience of the user.

If the lid doesn't open, don't use excessive force, see if there's a big object stuck, like a sock or a wire that's blocking the mechanism, and the plastic latches are strong enough, but if you jerk them abruptly, they can break, which will require you to replace the entire bottom panel.

💡

If the latches are tight, try tapping your finger slightly on them in the direction of opening – this will help relieve the internal stress of the plastic.

When you remove the lid, you'll see the brush and the air intake grille, which is where the major contaminants accumulate most often. Visually assess the pollution: if the pile is tightly wrapped around the shaft, it needs to be carefully cut before being removed.

Technology of removing a brush from a seat

The extraction process requires care. The brush is inserted into the grooves on both sides and fixed by special holders. Xiaomi models often use a system where one end of the shaft has a hexagonal or square cross section to transmit rotation, and the other simply enters the bearing.

To pull the piece out, you first need to get rid of the debris. If you try to pull out a heavily contaminated brush, you can damage the plastic gears of the gearbox. Take the scissors and carefully cut the wound hair and threads, trying not to scratch the shaft itself and the inner surface of the case.

Once cleaned, grab the center of the brush or hold special knobs around the edges (if designed). Pull the shaft upwards in a smooth but steady motion. It should exit the seats without squeaking or jamming. If the shaft is sitting tight, swing it from side to side to loosen.

When removing the shaft, try not to drop the cut debris inside these holes, as it will be extremely difficult to get it out of there without a complete disassembly of the body.

Cleaning and maintenance of the cleaning element

Once you've managed to pull out the brush, you go through a deep cleaning phase, and it's not enough to just shake off the dust, you have to remove all the fibers that fit tightly into the bristles, and use the scissors to cut the fibers along the shaft, and then remove the rings that come out.

Notice the bearings at the edges of the shaft. This is where long hair is most often wound, and you have to clean it out, otherwise the shaft will rotate with difficulty, leading to an Error 6 error or a similar engine malfunction code in the app, and you can use a toothpick or a thin needle to clean it.

• 🌪️ Carefully remove all debris from the bristles by brushing it with your fingers.
• 🧼 If you have a lot of pollution, you can wash your brush with water, but only if it is allowed by the instructions for your model (usually plastic rollers can be washed).
• ⏳ Before you put it back in, the brush should dry completely (at least 24 hours) if you wash it.

⚠️ Warning: It is strictly forbidden to install a wet brush back into the robot vacuum cleaner. Getting water on the electronic contacts of the engine or inside the housing can cause short circuit and irreversible failure of the device.

While the brush is drying (if it was wet cleaning) or while you are cleaning it, wipe the inside of the compartment with a wet wipe. Remove dust from contacts and sensors. The cleanliness inside the case directly affects the quality of suction and the leakage of the filtration system.

Installation of the brush back and check the work

When the brush is cleaned and (if necessary) dried, it can be put in place. Notice the shape of the shaft ends: they're not symmetrical. One end has protrusions (slits) that should match the engine response, and manufacturers usually mark the correct end with color or shape.

Put one end of the shaft into the seat, then gently lower the other. The brush should lie flat, without skewing. If you feel resistance, don't push, check for orientation. Incorrect installation can cause the plastic gears of the drive to break when switched on.

Once the shaft is installed, close the module lid until the characteristic click. Make sure all latches fall into place and there are no gaps. Now turn the robot over, turn it on, and start a short cleaning or Charging mode to listen to the engine.

💡

If a properly installed brush rotates silently, if a hum or a grinding appears after assembly, immediately stop the device and check for the shaft to re-set.

Run the Mi Home app and check the status of the device. If the system has diagnosed an engine error before, after successful cleaning and restarting, it should reset. The robot is ready to work fully and will clean up with maximum efficiency.

Frequent problems and their solution

Sometimes users are faced with a situation where the brush is pulled, cleaned, installed, but the robot continues to give a mistake or is not working correctly, most often because the debris got deeper into the duct duct duct, or the brush itself was worn out.

The life of the main brush is about 6-12 months depending on the intensity of use and the type of flooring. If the bristles are worn, become too soft or deformed, no cleaning will return to its original properties, in which case it is necessary to replace the consumable with a new original or quality counterpart.

Also, the problem can be in the side brush, which is often overlooked. Check its condition: if it is broken or badly worn, the robot will be worse to clean along the walls, even if the main turbobrush works perfectly. Regular inspection of all moving parts is the key to the longevity of Xiaomi equipment.

• 🔍 Check the side brush at every second brushing of the main brush.
• 🗑️ Clean collision sensors and wheels from wound hair.
• 🔄 Change. HEPA-filter according to the schedule, so as not to reduce the thrust of the engine.

Compliance with these simple maintenance rules will allow your Xiaomi Mi Robot Vacuum Mop to last for years without losing suction power. Regular care of machinery pays off with stable operation and cleanliness in the house.
