Modern automatic cleaning assistants require regular maintenance, and one of the key steps in this process is to replace the filter elements in a timely manner. If you are wondering how to change the Xiaomi filter in a robot vacuum cleaner, then the device has begun to suck up dust or make extraneous sounds. Ignoring this procedure can lead to engine overheating and reduce the quality of air cleaning in the room.
In this article, we will discuss the replacement process in detail. HEPA-We're going to talk about the differences between the consumable models and explain why you can't just wash an old piece with water.
You have to understand that the filtration system in Xiaomi and Roborock is designed to trap the smallest particles of dust, allergens and animal hair. Over time, the pores of the material get clogged, the airflow resistance grows, and the motor is running at increased load, which is why it's important to monitor the condition of the filter unit.
Types of filters and their differences in Xiaomi models
Before you start replacing, you need to make sure you get the right type of consumable. The Chinese giant's robot vacuum cleaners use different cleaning systems depending on the batch and year of release. HEPA-filters that trap up to 99% of microparticles and prefilters made of spongy material.
The main difference lies in the design of the body and the landing dimensions. For example, the S50 and S5 Max series use rectangular filters with a plastic frame, while newer versions, such as the Xiaomi Vacuum Mop 2 Pro, can be changed to increase the filtration area. There are also washable versions, but their resource is much lower than that of disposable counterparts.
⚠️ Note: Using filters of inadequate size or design can cause fine dust to enter the engine turbine directly, causing rapid wear or breakage.
When choosing a new item, pay attention to the marking. Original components usually have a hologram or QR-Chinese counterparts may cost less, but the quality of the paper in them often leaves much to be desired, which reduces the efficiency of cleaning.
⚠️ Note: Do not try to use filters from other brands (e.g. iRobot or Ecovacs) without adapting, as the geometry of their mounting is radically different.
When to replace: signs and timing
The manufacturer recommends changing the main filter element every 6 months in normal use, but the actual life of the room depends on the area of the cleaned room, the presence of pets and the dustiness of the apartment. If you have a cat or dog, the interval should be reduced to 3-4 months.
The robot may start returning to base early, reporting an error, or simply stop collecting garbage from the carpet effectively. Mi Home can also send maintenance notifications if your model has such a feature in the algorithm.
Visual inspection is the most reliable way to diagnose, because if the white filter material has become gray or black, and the structure of the paper has become dense, then the pores are clogged, and in this case, water washing will not help restore the permeability, because the microscopic dust clogs the fibers.
Tools and preparation for maintenance
The replacement procedure does not require any complex tools or special skills. You will only need a new set of filters and possibly a small brush to pre-clean the compartment. Before starting work, make sure the robot vacuum cleaner is off or in sleep mode.
It is best to maintain on a flat surface with good lighting so that small details do not get lost. Prepare the trash can in advance for recycling the old consumable, as the accumulated dust can pour out when extracted.
☑️ Preparation for filter replacement
Some users prefer to swap over the sink or in the bathroom to wash away the dust that has fallen outside immediately, but be careful not to let water get inside the robot body, especially in the area of charging contacts or sensors.
Step-by-step: how to change the filter in the robot Xiaomi
First, turn the robot vacuum cleaner upside down. Find the cover of the main dust collection container. In most models, such as the Xiaomi Mi Robot Vacuum or the Roborock S5, it opens by pressing the locks on the sides or back. Carefully remove the container.
Open the lid of the dust collector itself, and you'll see inside the compartment where the filter is located, and depending on the design, the filter can be installed vertically or horizontally, grab a plastic handle or a filter tongue and smoothly pull it over.
⚠️ Warning: Avoid sudden movements when removing the old filter so as not to spill accumulated dust back into the compartment or onto the floor.
Install the new filter into the slots until the characteristic click or tight fit. Make sure it sits flat and is not skewed. Then close the container lid and insert it back into the robot body until it is fixed.
Do I need to reset the filter timer?
After assembly, turn on the device and start a short cleaning to make sure that there is no extraneous noise and the suction system is working properly. If the robot is quiet and confident, then the replacement was successful.
Comparison of filter characteristics of different series
To make it easier for you to navigate the variety of models, we have prepared a table with the main characteristics of filter elements for popular robot lines, which will help avoid mistakes when buying consumables.
| Model robot. | Type of filter | Resource (mo) | Can I wash? |
|---|---|---|---|
| Xiaomi Mi Robot 1S / S5 | HEPA E11 | 6-12 | No. |
| Roborock S5 Max | HEPA E11 (reinforced) | 6 | No. |
| Xiaomi Mop Essential | HEPA + sponge | 3-6 | Just a sponge. |
| Roborock S7 / S8 | HEPA E12 (washable) | 6 | Yeah (careful) |
As you can see from the table, even within the same brand, there can be different types of materials, and models with washable filters have appeared relatively recently, but even their manufacturers recommend changing them every six months to maintain efficiency.
If you use a robot in a room with high humidity or a lot of fine building dust, the filter life can be reduced by half, and in such conditions, you should have a spare kit.
Frequent errors in replacement and operation
One of the most common mistakes is to try washing disposables. HEPA-The paper that they're made of swells up from the water, loses its structure, and stops trapping small particles, and when it's drying, it turns into a useless cloth that lets dust into the engine.
💡
If you do decide to wash the filter (only if the instructions allow it), do so under a weak stream of cold water without detergents and dry for at least 24 hours in a horizontal position.
Another mistake is to install a filter with a damaged sealing gum, so if the seal is torn or crumpled, air will pass the filter element, taking the dust with it, and always check the integrity of the seals before installing.
Users also often forget to clean the container compartment itself of dust before installing a new element, and the residue of dirt on the walls can quickly clog a new filter or enter the turbine.
