Robot vacuum cleaners from Xiaomi and Dreame have become an integral part of the modern smart home, making it much easier to keep clean. However, like any complex technique, they require regular maintenance to maintain high performance. Ignoring the device's hygiene can lead to reduced suction force, extraneous noises and even engine failure.
In this article, we will discuss how to properly maintain your assistant’s various nodes so that it will last for many years, what tools you will need, how often you need to perform the procedure and what to pay special attention to.
Many users forget that a robot is not just a motor box, but a machine with many sensors and filters, and that a clogged filter or hair wound on a brush can put a critical strain on the system, and let's figure out how to avoid these problems and keep the device in perfect condition.
Preparation for maintenance and necessary tools
Before you start disassembling and cleaning, you need to prepare a workplace and a minimum set of tools, you don't need a complex professional tool, you will need what is in every house, the main rule is that all manipulations are carried out only on the device that is turned off.
Be sure to remove the battery or make sure the robot is switched off with a button if the design permits.This will prevent the motors from accidentally starting during cleaning, which can cause injury to the fingers or damage to the machinery, and it is also worth preparing a dry, well-lit surface where you will fold the removed parts.
☑️ Tools for cleaning a robot vacuum cleaner
For effective cleaning, you will need the following items:
- ✂️ Scissors or a special cleaning knife (often included) to remove hair from the roller.
- 🧹 Small brush for brushing dust from hard-to-reach places and sensors.
- 🧶 Dry microfibre or lilaless fabric for cleaning the case and sensors.
- 🔦 Lantern for inspection of internal cavities and detection of minor contaminants.
- 💨 A compressed air cylinder for blowing dust out of speaker grilles and sensors.
The use of water or wet wipes is only allowed on external plastic surfaces and the dust container (after the filter is removed). Electronic components, motors and filters must remain completely dry. Moisture inside the housing is a sure way to short circuit.
Cleaning the main dust container
The dust container is the first element that needs attention after every 2-3 cleanings, and this is where most of the garbage, wool and dust accumulates, and if you don't empty it in time, the suction efficiency drops, and the dust starts to seep back into the air through the motor.
To extract the container, you usually need to press a special button on the robot body or simply pull the handle, depending on the Xiaomi Vacuum or Dreame Bot model. Open the garbage compartment cover above the trash can. It is recommended to slightly tap on the walls of the container to shake off the fine dust stuck to the inner walls.
⚠️ Warning: Never wash the container with water unless the instructions for your particular model indicate otherwise.Moisture residues can mix with new dust, forming a dense lump that will block the airflow and damage the engine.
Pay special attention to the inlet through which air enters the container. There often form "jams" of dust and wool. Use a dry brush to clear this channel. Also check the filter net (if any in your model), which protects the main main part of the system. HEPA-large-faction filter.
💡
Wipe the dust collector with a dry cotton swab, and if the sensor is contaminated, the robot may misreport a full tank or fail to notice overflow.
Regular cleaning of the container prevents the appearance of unpleasant odor in the room, organic residues, such as hair or food particles, eventually begin to decompose, so at least once a week, wipe the insides of the container with a dry cloth.
Service HEPA-filtering and filtration systems
The filtration system is the lungs of your robot vacuum cleaner. Xiaomi and Dreame models most often use a bundle of prefilter and a bundle of prefilters. HEPA-It's the condition of the filter that determines how clean the air is when it leaves the device.
HEPA-filters are generally not washed with water unless the manufacturer has explicitly stated that they are washable; in most cases, they can only be gently knocked out or vacuumed from the outside. Frequently replacing or cleaning the filters is key to a long engine life.
| Type of filter | Frequency of cleaning | Can I wash? | Time of replacement |
|---|---|---|---|
| Prefilter (grid) | Once a week. | Yeah (with drying) | 6-12 months |
| HEPA-filter | Once every 2 weeks | No (usually) | 6-12 months |
| Engine filter | Once a month | No. | 12 months |
| Side brush | Once a month | No (wipe) | 6-12 months |
For cleaning. HEPA-Take it out of the container carefully, knock the end of the filter on the bottom of the trash can to dislodge the bulk of the dust, then use a dry brush to walk through the folds, if the filter is gray or black and not mechanically cleaned, it needs to be replaced. HEPA-filter is strictly prohibited, as water destroys the structure of the fibers, and the filter ceases to retain fine dust.
And don't forget the engine protection filter, which is often located separately, at the outlet of the robot body, which protects the engine itself from fine dust, and it's mandatory to clean it, otherwise the engine may overheat and burn.
Cleaning the main brush and side brooms
The main turbobrush is the working organ that comes in direct contact with the floor, and it's used to wrap animal hair, thread and hair, and over time, it creates a dense layer that blocks the roller from rotating and can cause the belt to break or break the bearings.
To clean, flip the robot over and remove the protective cover of the brush knot. It is usually attached to latches or screws (often a screw under the cross screwdriver). Take out the roller. Using scissors or a special tool from the kit, cut the wound hair along the groove and remove it. Clean the dust residue with a brush.
- 🌀 Check the bearings on both sides of the roller – they should rotate freely, without crunch.
- 🧶 Remove all wound fibers from the roller axis inside the robot body.
- 🔩 If the brush is completely removable, make sure that the teeth or bristles are not worn to a critical level.
Side brushes also require attention, remove them by pulling upwards and clear the hair at the base, check the bristles: if they are severely deformed or broken, the broomstick should be replaced, as it will no longer effectively drive debris to the main brush.
⚠️ Warning: When installing the main brush, be sure to position correctly. If you insert it backwards or not to the end, the robot will give an engine error or will work with strong noise and vibration.
Importantly, some new Dreame and Xiaomi models use stubbleless rollers (silicon or rubber) that are less susceptible to hair wounding, but they also need to be cleaned by removing dust and fine particles stuck in the rubber texture.
Care for sensors, wheels and contacts
The robot vacuum cleaner's navigation depends on a lot of sensors around the body's perimeter: the drop sensors (usually 4-6 pieces on the robot's skirt), the collision sensors and lidar (if any) must be clean, and the dust on them causes the robot to "go blind," it begins to beat obstacles or fall down stairs.
Wipe all the black sensor windows with dry soft cloth. Pay special attention to the sensors on the bottom panel — they often get clogged with dust the fastest. Also check the charging contacts on both the robot and the base. Oxidation or a layer of dust on the contacts will cause the robot to stop charging.
What to do if the robot loses the map?
Robot wheels are another important element. Over time, the axis of the wheels will wind hair, which can block their rotation. The robot will start to report a wheel error or just stand in place. Turn the device and spin the wheels with your hand. If they walk tight or crunch is heard, remove the wheel (if the design allows), or carefully clean the gap between the wheel and the body with a knife or tweezers.
To clean hard-to-reach areas around wheels and sensors, a compressed air canister is ideal. Short blowouts will help to knock dust out of the depths of the machinery without disassembling them completely. This is especially true for models with a laser rangefinder (LDS), where dust can get into the rotating unit.
Frequent errors and prevention of breakdowns
Many users make common mistakes that shorten the life of the device, the most common being trying to wash the entire body with a wet cloth, including the top with electronics, and water trapped in the speaker, buttons or panel joints causes contacts to corrosion and the control board to fail.
Another mistake is ignoring small objects on the floor. Large debris, socks, wires and bags can jam the brush dead, the robot will try to turn around by burning the engine, always do minimal preparation before starting: remove wires and large objects.
Do not use aggressive chemicals to wash the container or case. Alkaline or acidic products can eat up plastic, make it brittle or change color. Disinfection is better to use special household appliances or just water with a small amount of neutral soap (only for removable plastic parts, thoroughly drying them after).
💡
Regular prevention takes 10-15 minutes a month, but extends the life of a robot vacuum cleaner by 2-3 times, saving money on repairs or buying a new device.
Keep an eye out for software updates through the Mi Home or Dreamehome app. Manufacturers often release patches that improve the algorithms for bypassing obstacles and controlling suction power, which indirectly affects the degree of filter contamination.
Remember, cleanliness is the key to cleanliness in your home. Spending a little time maintaining Xiaomi or Dreame, you ensure you are comfortable and have no problems with the technology for many years. Regularity is the main secret of success.
💡
If you use a robot vacuum cleaner to clean animal hair, increase the brushing frequency to 2-3 times a week, and the wool tends to compact quickly and create traffic jams.
