Modern cleaning devices require regular maintenance to maintain high suction and navigation efficiency. Many smart appliance owners face a problem of reduced productivity after a few months of active use, often due to the banal contamination of internal machinery, filters and sensors that accumulate dust, wool and fine debris.
Regular cleaning of Xiaomi robot vacuum not only prolongs its life, but also prevents the appearance of unpleasant odors in the room. In this article, we will discuss in detail the process of maintenance of all key components, from the main container to hard-to-reach sensors. The correct approach to hygiene of the gadget ensures its stable operation for years.
Preparation for cleaning and precautions
Before any electronic manipulation begins, turn the device off completely, and then turn the robot vacuum cleaner over and find a mechanical power switch, usually located on the bottom panel next to the charging contacts, and move the switch to the OFF position to eliminate the risk of short circuit or accidental engine start during disassembly.
Prepare your workspace: you'll need a dry, clean surface with good lighting. Stock up on the necessary tools in advance: a soft microfiber, a dry toothbrush, hair removal tweezers and possibly a cross screwdriver to access the sidebrush. Don't use aggressive chemicals or abrasive materials that can damage the plastic of the case.
⚠️ Warning: It is strictly forbidden to wash the body of the robot, the main turbobrush and electronic blocks with water or a wet cloth.
It is important to understand that different Xiaomi models may have design features. For example, in the Roborock S5 or Viomi series, filter access may differ from the classic Mi Robot Vacuum models. Always check with the visual inspection of the device before using force.
☑️ Preparation for maintenance
Dust collector and filtration system maintenance
The central element that needs attention is the dust container, and that's where the bulk of the dirt settles, remove the dust collector from the robot body by opening the top cover, pour it into the trash can, tapping it neatly on the walls to remove the stuck dust from the corners.
The container itself can be washed under running water, but this should be done without the use of detergents that leave a slippery film. After washing, thoroughly wipe the container with a dry cloth and leave it to dry for at least 24 hours. A wet container installed back into the robot will instantly clog the filter and can damage the engine.
Special attention is required HEPA-This is a consumable that traps the smallest particles of dust and allergens. In most Xiaomi models, the filter is reusable and allows for careful dry brushing. Manufacturers do not recommend washing it with water, since the fibers of the material can deform and lose their properties.
- 🧹 Carefully knock the filter over the trash can to remove the large dust.
- 🌬️ Blow the filter on the back (from the clean air side) to remove fine dust.
- 🔍 Inspect the mesh for tears or severe contaminants that are not removed mechanically.
If the filter has a persistent odor or visible damage, it must be replaced. HEPA-The filter is usually 2 to 6 months depending on the intensity of use and the presence of pets.The use of a damaged filter will lead to dust entering the engine, which is a critical malfunction.
How often do I change the filter?
Cleaning the main turbo brush
The main brush is the heart of your robot's mechanical cleaning, and flip the device over and remove the protective grille by snapping the locks off, remove the brush shaft, and it's used to wield hair, wool and threads that create resistance and can burn the motor.
Use scissors or a special blade (often included) to cut the tangled hair along the shaft. After that, remove the wound material with your hands. Pay special attention to the ends of the brush where the bearings are located: this is where the dirt that blocks the rotation most often accumulates.
The plastic shaft of the brush can be wiped with a wet but well-pressed napkin. Make sure there are no foreign objects left on the bristles. If the brush has rubber petals (as in Xiaomi Vacuum-Mop models), check their integrity and elasticity.
| Brush element | Type of pollution | Cleaning method | Frequency |
|---|---|---|---|
| Worse and bristles | Hair, thread, wool. | Mechanical removal with a knife/scissors | Every 1-2 weeks |
| Bearings (ends) | Dust, fine rubbish | Blowing and brushing with a toothbrush | Once a month |
| Brush body | Sticky dust | Washing with a dry or slightly wet cloth | As pollution progresses |
After cleaning, set the brush back, observing the color markings (usually gray and yellow on the ends correspond to the response parts in the case).
💡
To make it easier to clean your brush, keep an old toothbrush on hand.E stiff bristles are ideal for combing fine dust from bearings where tweezers can't get.
Care for side brush and wheels
The side brush is responsible for sweeping debris from the corners under the main turbine, it is attached to a screw or latch. Remove it by unscrewing the central screw (usually a cross screwdriver is required), clean the bristles of the wound hair and wipe the attachment mechanism.
The wheels of a robot vacuum cleaner are often overlooked, even though they carry the device throughout the apartment. The hair around the axis of the wheels is constantly wound, which eventually blocks the course. If the robot starts to "stupidize," get stuck on the doorsteps or make strange noises when moving, the problem is almost always the wheels.
To clean the wheels, use tweezers or a thin screwdriver sting. Gently dent and remove the wound threads. Wipe the wheels with dry cloth to improve floor grip. Check if they are loosely scrolled and spring-loaded (should be slightly recessed when pressed).
- 🛑 Check the small front wheel: it is also prone to debris fouling.
- 🔄 Scroll the main wheels manually to make sure there is no jamming.
- 🧼 Wipe the charging contacts on the bottom of the robot with a dry cotton swab.
⚠️ Warning: Don't try to lubricate the wheels with oil or silicone lubrication.The sticky surface will start collecting dust even faster, turning into abrasive porridge that will destroy the mechanism.
Once all the moving elements are cleaned, assemble the device in reverse order, make sure all the lids are snapped to a characteristic click, and a loosely closed brush compartment can result in a loss of suction power.
Cleaning sensors and navigation systems
Modern Xiaomi robots are equipped with a complex system of sensors: the fall sensors (located around the perimeter of the bottom), the collision sensors (bumper) and the laser rangefinder (LDS) on the top cover should be perfectly clean.
Wipe all the black windows of the sensors with a soft microfiber. Dust on the fall sensors can make the robot think it's hanging in the air and it will refuse to go. Mud on the laser rangefinder will lead to an incorrect map and chaotic movement.
Pay special attention to the window of the laser rangefinder, if you notice a stain or a layer of dust on it, gently wipe it with a dry cloth. Do not use alcohol or wipers, they can damage the transparency of the plastic or anti-reflective coating.
Check the charging contacts on the robot itself and at the docking station, and oxidation or dust plaque on them leads to poor contact: the robot may not charge or permanently lose connection when leaving the base.
Disinfection and elimination of odors
Over time, mold or bacteria can settle inside the dust collector and ducts, especially if you have removed wet debris or spilled liquids. You can use special sprays for equipment to disinfect, or simply thoroughly wash and dry the container.
Some users put a cotton pad moistened with essential oil in a container (not in the engine bay!), but Xiaomi manufacturers do not recommend this, as pairs of oils can break down plastic and rubber seals.
If the robot smells of burning, stop operating immediately, which may indicate that the engine overheats or a foreign object enters the turbine, in which case professional diagnostics is required.
💡
Cleaning sensors and charging contacts regularly is key to proper navigation and battery life, and dirty sensors make the robot idle, using up battery power.
