How to get a filter from a robot vacuum cleaner Xiaomi: instructions for all models

The filters in Xiaomi’s robot vacuum cleaners are a critical element that not only determines the quality of the cleaning, but also the life of the device. A dust-filled filter reduces suction power, increases engine load and can cause engine failure. However, many users have difficulty trying to remove it: the latches break, the covers don’t open, and instructions often lack details.

In this article, we will discuss the step-by-step process of filter extraction for all popular Xiaomi models (including Mi Robot Vacuum, Viomi and Dreame), talk about the types of filters and their resource, and also warn against typical errors that shorten the life of technology. If your vacuum cleaner begins to collect garbage worse or emits uncharacteristic noise, most likely, the problem is in the filter.

The frequency of filter cleaning depends on the intensity of the vacuum cleaner use, and on average, manufacturers recommend washing it every 2-4 weeks and replacing it every 3-6 months. However, in homes with animals or allergies, this interval is reduced by half, neglect of care leads to the vacuum cleaner spitting dust back into the air, negating the benefits of cleaning.

It is important to understand that the design of filters in different models of Xiaomi can be different. For example, in the Mi Robot Vacuum-Mop 2 Lite filter is hidden under the removable cover of the dust container, and in the Dreame Bot Z10 Pro it has to be pulled through the bottom panel, we will consider all options so that you can quickly navigate.

Types of filters in Xiaomi robot vacuum cleaners: what do you have?

Before you start extracting, determine what type of filter is installed in your model, and it depends on the algorithm of actions and the frequency of maintenance. There are three main types:

1. HEPA-filters (most common) - capture up to 99.97% of particles up to 0.3 microns in size, installed in most Mi Robot and Viomi models, require regular washing and replacement every six months.

2. Coal filters, which further neutralize odors, are found in premium models, such as the Dreame Bot W10. They can not be washed, only replaced every 2-3 months.

3. Mesh filters (in budget models) - only trap large dust. They can be washed under running water, but they are less efficient.

To find out the exact type, check the labeling on the filter itself or in the device documentation, for example, the words "HEPA 12" indicate a high-performance filter, and "Activated Carbon" - coal.

Step-by-step: how to get a filter from a Xiaomi vacuum cleaner

The process of filter extraction varies from model to model, but the overall algorithm is similar. Below we will discuss a universal method that is suitable for 90% of Xiaomi devices. If your model has a unique design, see the section on specific series.

Step 1. Turn the vacuum cleaner off the power supply

Before any manipulation of the internal components, be sure to remove the battery or disconnect the device from the charging station.This will prevent accidental switching on during disassembly and protect the electronics from short circuit.

Step 2. Remove the dust collector.

In most models, the filter is located inside the garbage container.

1. Turn the vacuum cleaner (day up).
2. Press a button or latch (usually marked with an arrow or PUSH).
3. Pull the container over yourself - it should come out effortlessly.

Step 3. Remove the filter

Inside the dust collector, you'll see a filter element, and it may have different attachments.

• 🔹 Latches on the sides – press them at the same time and pull the filter up.
• 🔹 Threaded mount - Turn counterclockwise (found in Dreame Bot) L10).
• 🔹 Magnetic fastening – just pull with effort (typical for Viomi) V3).

Step 4: Cleaning or Replacement

If the filter is reusable (HEPA or mesh), rinse it under warm water without detergents. Dry for at least 24 hours in a ventilated place. Coal filters can not be washed - they are only replaced.

⚠️ Warning: Never use a hair dryer or microwave to dry the filter! high temperatures destroy fibres HEPA, reducing the efficiency of filtration.

Features of filter extraction in popular models

Some Xiaomi robot vacuum cleaners have a unique design, and below are details for the most common series.

For the Viomi and Dreame models with dual filtration system (coal + HEPA), it is important not to confuse the installation order: the carbon filter is always placed first along the air (closer to the fan), and HEPA - second.

Frequent errors in filter removal and care

Even experienced users sometimes make mistakes that lead to breakdowns.

1. Use of sharp objects

Do not try to tamper with a knife or a metal screwdriver, this will damage the plastic case or the filter element itself. Use only plastic blades or special devices.

Incomplete drying before installation

The wet filter becomes a breeding ground for bacteria and mold. HEPA-filter, dry it for at least a day in a well-ventilated place.

3. Filter setup backwards

Most filters have an arrow that indicates the direction of the airflow (usually AIR FLOW), and if you put it wrong, the filtration efficiency will drop by 30 to 50 percent.

4. Ignoring the replacement of the carbon filter

Carbon filters are not refurbishable, they last 2-3 months, after which they stop absorbing odors and begin to emit an unpleasant odor.

⚠️ Warning: If the vacuum cleaner is louder after cleaning the filter, check if dust has entered the fan, which can lead to engine overheating and expensive repairs.

💡

To extend life HEPA-before washing carefully vacuum it with a conventional vacuum cleaner at minimum power, this will remove large particles of dust and facilitate further cleaning.

How often should the filter be cleaned or changed?

Xiaomi manufacturers give general recommendations, but the real interval depends on the operating conditions.

• 🏡 Standard conditions (1-2 cleanings per week): cleaning every 3-4 weeks, replacement every 6 months.
• 🐶 Homes with animals: cleaning every 1-2 weeks, replacing every 3 months.
• 🌿 Allergy/asthmatics: Clean weekly, replaced every 2 months.
• 🏗️ Repair/construction work: cleaning after each cleaning, replacement as pollution.

It is possible to understand that the filter needs replacement by the following signs:

• The vacuum cleaner has become worse at sucking up garbage.
• There was an unpleasant smell during work.
• Increased cleaning time (vacuum cleaner longer "thinks" and more often gets stuck).
• The filter shows traces of mold or it has lost shape.

💡

Regularly replacing the filter is cheaper than engine repair. HEPA-filter for Xiaomi – 300-800 rubles, while the replacement of the engine will cost 3-400 rubles.

Where to buy original filters for Xiaomi?

Using non-original filters can lead to a decrease in productivity or even breakage of the vacuum cleaner.

• 🛒 Xiaomi’s official store is a guarantee of originality, but prices are above average.

When buying, pay attention to:

Article (for example, for Mi Robot Vacuum 1S, it is ZNMS17AM).

Type of filter (HEPA, coal or combined).

Compatibility with the model (check in the description).

The cost of the original filters varies from 250 to 1500 rubles depending on the model. For example, the filter for Dreame Bot Z10 Pro will cost 800-1200 rubles, and for Mi Robot Vacuum-Mop 2 Lite - 300-500 rubles.

What to do if the filter is damaged or lost?

If the filter is broken, deformed or lost, don't try to operate the vacuum cleaner without it!

• The entry of dust into the engine and its premature wear.
• Deterioration of air quality in the room (dust will blow back out).
• Possible fire due to overheating.

An interim solution could be:

1. A homemade filter made of dense tissue (e.g. microfibers) folded in several layers, but this will reduce the efficiency of cleaning by 40-60%.

2. Filter from another vacuum cleaner (if the dimensions are the same) Filters from Roborock or Ecovacs will do, but check compatibility.

3.Order 3D-printing – some workshops make filters to order according to the template.

Once you have the opportunity, install the original filter, which will cost you more to repair.

💡

If you are temporarily using a vacuum cleaner without a filter, reduce the cleaning time to 10-15 minutes and avoid long-pile carpets.
