How to clean the filter of the vacuum cleaner Xiaomi: step-by-step instructions with photos and tips

Why cleaning Xiaomi filters is not just a recommendation, but a necessity

Xiaomi vacuum cleaners are some of the most popular cleaning assistants, thanks to their combination of power, compactness and smart features. But even the most advanced technology requires maintenance, and filters play a key role here. HEPA-A filter or dirty motor filter not only reduces the suction efficiency by 30-50% (according to Xiaomi Lab tests), but also forcedly increases the load on the engine, reducing the life of the vacuum cleaner by 1.5-2 times.

In this article, you will find detailed instructions for cleaning all types of filters for Mi Robot Vacuum, Mi Handheld Vacuum, Dreame and other brands, from classic vertical vacuum cleaners to robot vacuum cleaners, we will analyze which filters can be washed, which ones can be soaked, how often to do it, and what will happen if you ignore the care.

What filters are in the vacuum cleaners Xiaomi and why they need

Depending on the model, Xiaomi vacuum cleaners are equipped with 1-3 types of filters, each performs its function, and all require regular maintenance:

• 🔹 HEPA-filter - captures the smallest particles (up to 0.3 microns), including pollen, bacteria and allergens. G10 or dreame V12.
• 🔹 Motor (pre-motor) filter - protects the engine from large debris and hair, usually a foam or synthetic sponge.
• 🔹 Cyclone filter – separates dust from air in cyclone-enabled systems (e.g. Mi Vacuum Cleaner) 1C). Often made in the form of a plastic container with a grid.
• 🔹 Coal filter – neutralizes odors (less common, for example, in some versions of Dreame Bot).

It's important to understand that replacing and cleaning these filters is not a marketing move, but a technical necessity. HEPA-The filter can cause an error. E3 (overheating of the engine) in Xiaomi robot vacuum cleaners, and a dirty motor filter - to lose suction power by 40% or more.

When and how often to clean filters: signs and schedule

Xiaomi recommends cleaning filters every 1-3 months depending on the intensity of use, but in practice this interval can be reduced to 2-3 weeks if:

• 🐕 There are pets in the house (wool and dandruff clog filters 2 times faster).
• 🏗️ Repairs or often removes construction dust.
• 🌿 You live in a region with high humidity or dusty roads.
• 🚗 The vacuum cleaner is used to clean the interior of the car (mud and oil particles clog pores faster).

The fact that the filters require urgent cleaning, the following signs indicate:

If you use a Xiaomi vacuum cleaner daily, keep a cleaning calendar. For example, you can set reminders in the Mi Home app. For robot vacuum cleaners like Mi Robot Vacuum-Mop 2, the manufacturer even added a filter pollution alert feature — watch for notifications in the app.

💡

After cleaning up (for example, before the holidays), be sure to check the filters - even if the cleaning schedule was not planned.

Step-by-step instructions: how to clean HEPA-filter in Xiaomi vacuum cleaners

HEPA-The filter is the most delicate part of the vacuum cleaner, and you can't clean it with aggressive means or dry it with a hair dryer, or it will lose its properties:

1. Disconnect the vacuum cleaner from the mains. In handheld models (e.g. Mi Handheld Vacuum), the filter is usually behind the removable lid on the handle. In robot vacuum cleaners (Mi Robot Vacuum) - under the top panel, next to the vacuum collector. Carefully pull the filter on yourself, it should come out effortlessly.
2. Shake off large dust particles over the trash can. Don't use a brush, it can damage microfibers. Use a vacuum cleaner with a soft nozzle at minimum power for hard-to-reach areas.
3. Washing fill the basin with warm water (not higher than 40)°C) and add a neutral detergent (e.g., dishwashing liquid) and immerse the filter in water and massage your fingers gently for 1-2 minutes — HEPA-The filter consists of thin fibers that are easily damaged.
4. Gargle and dry thoroughly rinse the filter under running water until traces of the detergent disappear. Then shake off the water and leave to dry for 24 to 48 hours in a well-ventilated place. HEPA-filter will lead to mold growth and breakage of the vacuum cleaner.

For fixed-models HEPA-filter (e.g. some versions of Dreame) V11) Use a spray filter cleaner, spray it on the surface, let it soak for 5-10 minutes, then remove the excess with a napkin.

⚠️ Attention: Never dry HEPA-filter in the microwave, oven or direct sunlight, high temperature will deform the fibers, and the filter will lose its properties, and avoid products with chlorine or bleach, they destroy the material.

Cleaning motor and cyclone filters: what can and can not be done

The motor filter is usually a foam sponge or synthetic sponge, which is cleaned differently than HEPA:

• 🧽 Washing: Use warm water with soap or dishware, and you can gently press the sponge, but not twist it, it will damage the structure.
• 🧼 Deep cleaning: to remove greasy spots (relevant for vacuum cleaners used in the kitchen), soak the filter in a solution of water and soda (1 tbsp. spoon per 1 l) for 15-20 minutes.
• 🔄 Drying: 4-6 hours outdoors is enough, you can use a fan to speed up the process, but do not direct the airflow too close.

The cyclone filter (if you have one in your model) is cleaned as follows:

1. Disconnect the dust collector from the hull.
2. Remove the cyclone filter – it’s usually a plastic container with a mesh.
3. Wash the netting under running water using a soft brush to remove the adhesive dust.
4. Dry all the parts before assembly. The moisture in the cyclone filter can cause E2 (sensor closure) error in robot vacuum cleaners.

For carbon filter models (such as Dreame Bot W10), there is no cleaning, it can only be replaced, and the carbon filter life is 6-12 months, depending on the intensity of use.

Errors in cleaning filters that shorten the life of the vacuum cleaner

Even experienced users sometimes make mistakes that lead to breakdowns.

• 🚫 Using hot water — HEPA-filters deform at temperatures above 40°C, and foam filters may "sit down".
• 🚫 Drying with a hair dryer or on a battery - this leads to shrinkage of materials and loss of filter properties.
• 🚫 Cleaning with hard brushes or metal sponges – scratches the surface of the filters, creating microcracks, through which the dust then passes.
• 🚫 Use of aggressive chemistry (acetone, gasoline, concentrated acids) – destroys adhesive compounds and filter materials.
• 🚫 Installing a wet filter – leads to short circuit (in robot vacuum cleaners) or mold growth.

Another common mistake is that you build the wrong thing after cleaning, like if you install it in a tight way. HEPA-filter in Mi Handheld Vacuum, vacuum cleaner will lose power due to air suction. Always check that the filter is in place before clicking, and sealing gums are not twisted.

⚠️ Attention: In vacuum cleaners Xiaomi Dreame V12 And then you have to reset the resource counter in the Mi Home app after cleaning the filters, otherwise the vacuum cleaner may show false errors. → Resetting the filter counter.

How to extend the life of filters: tips from Xiaomi service centers

Employees of authorized Xiaomi service centers share practical tips that help to clean filters less often and keep them working longer:

• 🌬️ Clean the dust collector regularly after each cleaning.A full container increases the load on the filters.
• 🧹 Use a nozzle with a brush for pre-cleaning large debris (hair, thread) - they most quickly clog the motor filter.
• 🚿 Wash filters in cool water (20–25)°C) – it damages materials less than warm.
• 📅 Keep a cleaning log – mark dates on the Mi Home calendar or app to avoid missing scheduled maintenance.
• 🛒 Buy original filters – non-original filters may not fit in size or material, which will lead to breakdown.

For owners of robot vacuum cleaners, Xiaomi has an additional life hack: set the cleaning area away from long-pile carpets. Pile fibers quickly clog filters, especially if the vacuum cleaner is used daily. In the Mi Home app, this is done through the Map → Cleaning Zones → Add a no-go area.

💡

Xiaomi’s original filters last 2-3 times longer than the non-original ones, even at the same cleaning frequency.
