How to change the filter Xiaomi Vacuum: the complete guide

Xiaomi’s modern robot vacuum cleaners have proven to be reliable tools for keeping the house clean. However, even the most advanced filtration system requires regular maintenance to maintain suction efficiency. Many owners face a situation where the device starts to work noisier or worse collect dust, unaware that the problem lies in clogged filtration elements.

Timely replacement of consumables is not just a whim, but a necessity to extend the life of the engine. In this article, we will discuss in detail how to determine the need for replacement, what tools will be required, and how to install new components in Xiaomi Robot Vacuum and Roborock models.

Do not ignore the app signals or indicators on the case, as contaminated HEPA-The right air purification system care ensures that your gadget will delight you with a great job for many years to come.

Symptoms of pollution and the need for replacement

You can tell when it's time to change your consumables not only after the calendar deadline, but also by indirect signs of the device's operation. First of all, look at the status indicators, which often flash red or display a notification in the Mi Home mobile app, which is the most direct signal that the system's throughput has fallen to a critical level.

The second sign is the change in the sound of the work, and if the robot starts to hum louder than usual, it means that the engine has to put more effort into pumping air through the clogged membrane, and you can also notice that after cleaning the floor, there is little debris or dust left on the floor, even though the device previously handled this efficiently.

Visual inspection also gives you a lot, and if you take out the container and look at the filter, the white color of the material should alert you, and the gray, black or brown shade indicates that the pores are completely clogged with dust and microparticles.

• 🔴 The filter indicator burns red or flashes in the app.
• 🔊 There was a strange noise, hum or whistle when the turbine was working.
• 💨 Reduced suction force, the robot worse collects wool.
• 🌫️ From the exit hole, you smell dust or there is a small suspension.

⚠️ Warning: Operation of a robot with a critically clogged filter can lead to fine dust entering the engine, which will cause its failure and expensive repairs.

Types of filters in the Xiaomi system

Xiaomi's robot vacuum cleaners typically use a multi-stage cleaning system that has several key elements to it, and understanding their device will help maintain the equipment properly. HEPA-A filter that traps the smallest particles of dust, allergens and mold spores, is a corrugated material rolled up into a cylinder or folded into an accordion.

The second important component is the primary filter sponge, which is made of porous material and serves to trap large dust, hair and animal hair, protecting the more delicately. HEPA-In some models, such as the Xiaomi Mi Robot Vacuum 1S Roborock S5, These elements can be combined into a single module or divided into two separate parts.

Also worth mentioning is the side brush, which, although not a filter, directly affects the quality of the garbage supply to the main compartment. If the brush is worn out, the load on the filtration system increases, as more of the large fraction of dust enters the container.

Preparation for replacement of consumables

Before you start the replacement procedure, you need to prepare the workplace and new components. It is important to purchase original consumables or quality analogues, as cheap fakes can have the wrong density, which will violate the aerodynamics of suction. Make sure you have a new set of filters on hand that matches your robot model.

The process does not require a complicated tool. You will only need a dry soft cloth or a wipe to wipe the inner surfaces of the container. It is also recommended to prepare a small brush to remove dust from the sensors while you perform maintenance.

Be sure to turn off the robot vacuum cleaner before starting work, press and hold the power button or use the switch on the bottom panel if it is designed, this will prevent accidental start of the engine during maintenance.

Step-by-step instructions for replacing the filter

The replacement process is simple enough and takes only a few minutes: flip the robot vacuum cleaner bottom up to access the bottom panel. Find the dust collection container cover and tap the latching latches to remove it from the device body.

Open the dust collector lid. Inside, you'll see a mesh compartment that has a filter element installed. Depending on the model, it could be a single block or a separate sponge and HEPA. Carefully pull on the plastic tongue or the edge of the filter to extract it. Try to do this slowly so as not to raise the dust cloud.

Install the new element in the slots, making sure it fits tightly against the walls and doesn't hang. If your model has a pre-sponge, insert it first, then the main filter, close the container lid until the characteristic click and insert the container itself back into the robot body.

Sequence of action:


1. Extract the dust collector.




2. Open the top cover of the container.




3. Remove the old filter.




4. Insert a new filter (colored upside if marked).




5. Close the lid and install the container in the robot.

Once installed, start the device and check it to work. If the noise is gone and the suction force is restored, then you did everything right. Remember to reset the filter resource counter in the application, if this feature is available for your model.

⚠️ Warning: When removing an old filter, do not shake it over the floor or furniture.

💡

Wipe the container filling sensor (usually a small window on the case or lid) with a dry cotton swab every time you change the filter, and this will prevent false overflow signals.

Features of service of different models

Xiaomi’s lineup of devices and Roborock’s sub-brand are quite extensive, and designs may differ. For example, in the Xiaomi Vacuum Mop model, filter access can be done through the top cover without flipping the device, whereas classic circular models require bottom access.

Wet cleaning models often use a combined module where water and dust are separated. It is important not to mix the compartments and wet the electrical contacts when replaced. The Roborock S7 series and later uses a lifting platform, and the filter is located in a standard place, but has an increased filtration area.

Some advanced models are equipped with automatic self-cleaning stations, which use special bags and filters to finely clean the air coming out of the base, and they are replaced less often, about once every 2-3 months, but they can not be ignored, because it affects the environment in the house.

• 🤖 Classic models: filter inside a removable container.
• 💧 Models with detergent function: separate filter for dry garbage.
• 🏠 Self-cleaning bases: require replacement of the bag and HEPA-base-filter.

💡

Always check the model marking on the bottom sticker of the robot before buying new consumables, as the appearance of containers from different years of production can be deceptive.

Frequent errors in service

Robotic vacuum cleaners often make mistakes that negate the effectiveness of new filters, the most common being the attempt to wash a disposable vacuum cleaner. HEPA-The water breaks down the microscopic fibers, and once dry, the filter stops trapping fine dust, allowing it to enter the motor.

Another mistake is to use inappropriate analogues: Cheap filters can be too dense to overload the engine, or too rare to cause damage to cleaning quality. Always pay attention to the original article.

Also, users often forget to clean the container itself of fine dust that settles on the walls. Over time, this layer builds up and interferes with normal air circulation, even if the filter is new.

⚠️ Warning: Never install a wet or undrained filter back into the device.
