How to clean the robot vacuum cleaner Xiaomi Mi Robot Vacuum Mop: expert guide

Modern smart home devices require regular maintenance, and Xiaomi Mi Robot Vacuum Mop is no exception. Over time, cleaning efficiency may decline not because of engine or battery failure, but simply because of clogged filters or tangled wool. Understanding how to properly maintain the equipment prolongs its life and ensures cleanliness in the apartment.

Many users are faced with a situation where the vacuum cleaner starts to make noise, loses suction power or even gives out an error that the application describes with incomprehensible code. Often the solution lies in basic cleaning of key nodes. Regular maintenance avoids expensive repairs in the service center.

In this article, we will discuss in detail all the steps of cleaning the Xiaomi robot vacuum cleaner, paying attention to the nuances that are often forgotten even by experienced gadget owners. You will learn how to properly wash the container, clean the side brush and maintain the wheel modules. The right approach to the hygiene of the device is the key to its long and smooth operation.

Dismantling and cleaning of the dust container

The first and most obvious step is cleaning up the main dust collector, and that's where most of the garbage, dust and allergens accumulate. HEPA-The filter inside is the heart of the filtration system and requires special attention. If it's clogged, the engine runs overloaded, and the cleaning quality drops.

First, you need to remove the container from the body of the device. On the top cover of the Xiaomi Mi Robot Vacuum Mop, there is a handy handle that you need to pull upwards. Don't put too much effort into it, the locking mechanism is designed to be easily removed. After that, open the garbage compartment lid above the trash can.

Inside, you'll see a primary filter and maybe a spongy prefilter, and you'll need to gently knock them out with a little tap on the bucket wall. HEPA-The filter is allowed only in extreme cases and requires a complete drying of at least 24 hours, otherwise moisture will enter the motor and cause a short circuit.

⚠️ Warning: It is strictly forbidden to operate a robot vacuum cleaner without a filter installed, which will lead to rapid engine failure and fine dust entering electronic components.

After cleaning the filter, wash the plastic container with warm water. Make sure there is no small debris left inside that could get stuck in the corners. Make sure that all parts are completely dry before assembly. A moist container can cause bacteria to grow and smell bad.

• 🗑️ Shake out the garbage after each cleaning to maintain suction power.
• 💧 Wash the container with water, but dry the filter only dry.
• 👃 Regularly check the sealing rubber for leakage.

Maintenance of the main and side brushes

The brushes are the working organ of your robot vacuum cleaner, and they are the ones most commonly affected by the wounding of animal hair, thread and fur. The main brush (turbobrush) is located at the bottom and is responsible for knocking dust out of the carpets. The side brush drives debris from under the boards to the central opening.

To clean the main brush, flip the device over and press the locks on the sides of the casing. Remove the protective cover and remove the shaft of the brush. Often, dense lumps of hair accumulate at the ends of the shaft that block rotation. Use scissors or a special knife from the kit to carefully cut the wound fibers.

The side brush is mounted on a screw or latch (depending on the revision of the model), it also needs to be removed and cleaned of dirt. If the brush is deformed or the bristles are worn, it should be replaced, because the cleaning efficiency at the edges of the walls will decrease dramatically. The wear of the bristles is a natural process that requires periodic replacement of consumables.

Notice the bearings that the main brush rotates on, if they're clogged with dirt, the brush will be hard to spin, putting extra strain on the engine. A drop of silicone lubricant (not WD-40!) will help restore ease of travel, but apply it very carefully, avoiding rubber parts.

• ✂️ Use scissors to remove hair from the shaft of the main brush.
• 🔄 Change your side brush every time 3-6 months of active use.
• 🧹 Check for no cracks on plastic brush blades.

Cleaning sensors and navigation systems

The Xiaomi Mi Robot Vacuum Mop is equipped with a whole system of sensors that allow it to navigate in space and not fall down stairs. Optical sensors located on the bottom and around the bumper, over time, become covered with a layer of dust, which can cause the robot to begin to “lose”, encounter obstacles or, worse, fall from the thresholds.

It's especially important to wipe the drop sensors that are on the bottom of the body, and they emit infrared light and analyze the reflection, and a layer of dust can scatter that light, and the robot will think there's a cliff ahead, even if it's standing on a flat floor, and wipe it with a soft, dry cloth without pile.

⚠️ Warning: Do not use wet wipes with alcohol or aggressive chemicals to wipe the sensors. The liquid can leak in and damage the electronics, and the chemistry can cloud the optics.

Also check the laser rangefinder (LDS) if your model is equipped with a turret on top. The rotating mechanism should not have backlashes, and the laser window should be clean. Dust on the laser emitter lens distorts the map of the room, leading to incorrect cleaning routes. Gently blow the hole or wipe it with a dry cotton swab.

Regularly checking the cleanness of sensors is a prevention of logical errors: a robot that "sees" the world clearly, works faster and consumes battery power more efficiently, because it does not make unnecessary movements and repeat trips in the same area.

Care of wheels and chassis

The wheel module is the basis of the mobility of the device, and in the process of operation, dust, wool and small debris are stuffed in and around the wheels, which creates resistance to rotation, which causes the motor wheel to run at its limits, symptoms of pollution can be creaking, difficulty overcoming thresholds or a "robot stuck" error.

To clean the wheels, flip the robot vacuum cleaner. Try to spin each wheel with your hand, the stroke should be free and springy. If the wheel is curling with difficulty or you hear a crunch, you need to remove the wound threads. Use tweezers or toothpick to extract dirt from the gaps between the wheel and the body.

Special attention should be paid to the charging contacts. On the bottom of the body and on the base are metal plates or pins. Oxidation or contamination of these contacts leads to the fact that the robot can not charge or constantly interrupts charging. Wipe the contacts with a dry cloth or cotton swab, slightly soaked in alcohol (make sure that the alcohol does not flow).

If the wheels are removed (in some models they are fixed by screws), they can be removed for a deeper cleaning of the axle. However, in most Xiaomi models, the wheels are not removable without full disassembly, so proceed carefully, not trying to pull them out by force.

• 🚲 Check the free running of all wheels manually at each cleaning.
• ⚡ Wipe the charging contacts every time you return to base.
• 🧵 Remove the wound hair with the wheel axles with tweezers.

Water problems: cleaning the tank and rags

In models with wet cleaning function (Mop), the condition of the water tank is critical. Using tap water leads to the formation of scale, which clogs the pores in the membrane and the water supply holes, the lime plaque can completely block the water supply, and the floor will remain dry.

It is recommended to use distilled or filtered water to fill the tank. If you still use tap water, periodically wash the tank with a solution of citric acid. This will help dissolve the resulting deposits.

The dirty, stagnant rag is a source of unpleasant odor and bacteria that the robot will smear across the floor. Also, the tough, dried rag collects dust worse and can scratch sensitive floor coverings. Use only soft microfibre wipes designed for robotic sinks.

💡

Use distilled water for the tank to prevent scale formation and prolong the life of the pump.

Notice the electric water supply valve (if you have one in your model) that is located on the tank or in the place where the tank is attached to the body. Make sure there is no dried dirt around the valve that can prevent it from closing tightly. Leaking water can damage the robot's electronics.

Frequent errors and ways to fix them

Even with regular cleaning, there may be situations where the Xiaomi Mi Robot Vacuum Mop reports an error, often due to contamination that surface cleaning failed to eliminate, such as the "Main brush blocked" error, which can occur if the hairs are stuck deep in the shaft bearings.

The "Wheel suspended" or "Wheel not rotating" error often signals that a large fraction of debris or a lump of dust has entered the mechanism, in which cases deeper disassembly or intense blowing of compressed air may be required. Don't ignore the sound signals - they help diagnose the problem at an early stage.

⚠️ Warning: If after thorough cleaning of all nodes error persists, do not disassemble the case yourself, if the device is warranty.

Sometimes the problem is not the robot itself, but the environment, where too dark carpets can blind the fall sensors, and black floors can disorient the optical sensors, and in such cases cleaning won't help, you'll need to adjust the virtual walls or change the cleaning parameters in the application.

Rebooting the device allows the system to re-interview all sensors and calibrate their readings, a simple but effective step before going to the service.

• 🔊 Listen to the error codes – they point to a specific node.
• 🔄 Reboot the system after a deep cleaning.
• 🌑 Consider the impact of color coatings on the work of sensors.
