Operating a robot vacuum cleaner inevitably faces maintenance needs, and most often owners are faced with the problem of winding hair, animal hair or threads on the axis of the drive wheel. If the Xiaomi Mi Robot vacuum cleaner makes an extraneous noise, gets stuck on the carpet or reports an error through the application, the mechanism is likely blocked by a foreign object.
Timely cleaning of moving elements prolongs the life of the engine and maintains the efficiency of cleaning. In this article, we will discuss in detail how to remove the Xiaomi Mi Robot wheel without damaging the body and plastic latches. You will learn about the necessary tools, nuances of disassembly of different generations of robots and precautions.
The dismantling procedure may seem complicated for a beginner, but with the right approach, it takes no more than 15-20 minutes. The main thing is to act carefully and consistently. The design feature of most models involves the use of special fasteners that require careful removal.
Before any electronic manipulation begins, a clean, well-lit workplace should be prepared, a flat-surfaced table covered with soft cloth or mat should be used to avoid scratching the glossy body of the device. The absence of dust in the work area is also critical, since the robot's open mechanisms should not be clogged during the repair process.
To successfully dismantle the wheel, you'll need a minimal set of tools, a cross screwdriver that's the size of the screws on the bottom of the robot, and some models, especially newer ones, may use hidden-head screws or special fasteners that require a specific tool.
It is not superfluous to prepare the screw folding tank in advance, as they tend to get lost. Also prepare tweezers and a dry brush to clean the insides of the mechanism from the accumulated dust immediately after removing the wheel. If you plan to lubricate the mechanism in the future, make sure that you have the right lubricant, although this is usually not required for initial cleaning.
Features of the design of the wheel module Xiaomi
Xiaomi’s robot vacuum cleaners and their sub-brands (Roborock, Viomi) feature two main drive wheels on the sides of the body. Each wheel is a separate module that is attached to the base with multiple screws and plastic fixtures. Inside the module is an electric motor and a gearbox that transmits torque.
The wheel is designed to provide maximum grip and the ability to overcome small thresholds. However, it is the complex shape of the tread and the gaps between the rubber tire and the plastic disc that become a garbage trap. Wrapping hair on the axle leads to increased engine load and eventual failure of the gears.
Why are the wheels locked?
The main reason why Xiaomi robots lock their wheels is because they have long hair and pet hair. When they wind on the axle, they form a dense cocoon that gradually hardens as it mixes with dust. This creates mechanical resistance that current sensors perceive as an obstacle or a breakdown, causing the cleaning to stop. It's important to understand that the wheel is not removed entirely with the rubber tire, but as a knot assembled with the engine. Disassembly of the wheel itself (separation of rubber from plastic) is usually not required and can lead to a violation of balance. Your task is to remove the entire module for cleaning the upper wheel, as a free-clearing process begins to remove the device. For safety, it's recommended that you remove the battery if your model's design allows you to do it quickly, or just make sure the robot isn't on charge and isn't performing the task. On the bottom panel, you'll see a few screws holding the plastic wheel casing. The number of these varies from two to four depending on the model (Xiaomi Vacuum Mop Essential, Roborock). S5, Xiaomi S10). Carefully unscrew all visible screws using a prepared screwdriver. Do not use excessive effort to avoid breaking the thread. After removing the screws, do not pull the module sharply. It can be held on plastic latches or connected by a plume (in rare cases, if the wheel sensor is made separately, but more often the module is self-contained). Carefully tuck the edge of the module with a flat screwdriver or mediator and swing it from side to side. ⚠️ Note: Do not use force to remove the module. If the wheel is not removed after the screws are twisted, check if there is another hidden screw left under the sticker or rubber leg, or if the wires inside the body are not interfering. When the module is freed from the mounts, smoothly remove it from the seat. Pay attention to the state of contacts and the purity of the cavity where the wheel is installed. Often it is in this recess that the main layer of dust accumulates, which also needs to be removed. Clean and maintain the mechanism Once you manage to remove the Xiaomi Mi Robot wheel, the maintenance stage comes. Visually inspect it from the landing place, and not to easily squerelate the wheels, and use them freely to remove them from the axis, so that it does not s, and use them. If the wheel is rotated tightly after cleaning the mechanical obstacles, it may be a problem with the bearing wear or moisture getting inside the motor. 📊 Long hair Strands and pile carpet Small debris and dust Do not forget to clean the niche in the body of the robot. Dust that has accumulated there can again fall on the axle immediately after installing the wheel. Blow the hole with compressed air or gently walk through with a dry brush.Make sure that the contact areas (if any) are clean and not oxidized. For comparison, below is a table showing the differences in the mounting of wheels in popular models: Robot model Number of screws Type of mounting Complexity of removing Xiaomi Robot Vacuum S10 3 screws Screw + latch Low Roborock S5 Max 2 screws Rotor Low Xiaomi Vacuum Mop Essential 4 screws Rotor Rotor E10 2 screws Rotor 2 screws Rotor + grooves Assembly is done in reverse order. Make sure that the wheels are oriented screws without twisting, they can be easily controlled by the mounting of the hulls to the base. 💡The correct installation of the wheel is characterized by the absence of backlash and free rotation of the wheel when scrolling with your hand. If the wheel wobbles or snags, remove the module and check the landing again. After installing all the elements, turn the robot over and turn it on. Run a test cleaning or just send the robot forward with a joystick in the app. Listen to the sound of the motors: it should be smooth, without humming or crackling, which could indicate skewed or debris. Typical errors and precautions One common mistake is to try to remove the wheel without twisting all the screws. In some models, a single screw can be hidden under a decorative pad or side brush. Always carefully inspect the perimeter of the module before using force. Another mistake is using harsh chemicals or water to clean the removed wheel. Water can get inside the motor, causing corrosion or short circuit. Use only dry cleaning methods or slightly moist fabric for the outer part of the rubber. ⚠️ Attention: It is strictly forbidden to lubricate the wheel axle with ordinary engine oil or WD-40. These substances attract dust, which turns into abrasive porridge, killing the mechanism in a matter of weeks.Use only dry cleaning or specialized lubricants for plastic, if this is explicitly indicated in the manual. If the robot continues to produce wheel error after cleaning and installation, check the sensors. Sometimes the problem is not the mechanics, but the contamination of the optical sensor or the malfunction of the motor-wheel itself, which requires its complete replacement. Frequently asked questions (FAQ) Can I wash the removed wheel under water? The rubber wheel itself can be washed, but you can't wet the metal axis and the plastic body of the module where the engine is located. The water inside the motor will cause it to fail. Only wipe the outside surface. How often do you remove and clean the wheels? The recommended frequency of preventive cleaning is once every 1-2 months. If you have pets with long hair, it costs you to check the wheels every 2-3 weeks. Regular inspection of the side brushes will also help prevent the hair from winding on the main wheels. What if the wheel screw is torn or lost? If the robot is in a larger diameter, if it is removed from a new carving, or if it is equivalent to the cartridge in the cartridge, then it is taken out of a new cartridge in the cartridge in the cartridge, or if it is taken out of the cartridge. The error can persist if the wheel is curved, if there is debris deep in the mechanism, or if the rotation sensor/motor itself is faulty. Try reinstalling the module. If persists error, you may need to replace the motor-wheel.
