Cleaning the filter of the robot vacuum cleaner Xiaomi: a detailed guide with photos and tips

Xiaomi’s vacuum cleaner robots are smart assistants that save you time and keep your home clean. But even the most advanced technology requires regular maintenance, especially when it comes to filters. A dust-filled filter not only reduces cleaning efficiency, but can also cause your device to break. In this article, we’ll look at how to properly clean the filter in Mi Robot, Dreame, Viomi and other models of the brand to extend their life.

Many users make mistakes when cleaning filters, such as washing them under hot water, using aggressive detergents, or forgetting to dry the part before installing it, and we'll tell you how to avoid these problems and keep the robot vacuum cleaner in perfect condition, and how often you need to clean the filter depending on the intensity of the device's use.

Why it is important to clean the robot vacuum filter regularly

The filter in Xiaomi’s robot vacuum cleaner has two key functions: it traps fine dust and prevents it from getting back into the air.

• 🔴 Reduced suction power – vacuum cleaner worse collects garbage, leaving dirt on the floor.
• 🔴 Overheating of the engine - due to poor air circulation, the engine is running at its limit, which reduces its resource.
• 🔴 Deterioration of air quality – dust particles penetrate back into the room, which is dangerous for allergic people.
• 🔴 Errors in operation – some models (for example, Mi Robot Vacuum-Mop 2 Pro) can give a Filter Blocked error and stop cleaning.

Studies have shown that a polluted filter increases the power consumption of a robot vacuum cleaner by 20 to 30 percent, because the engine requires more effort to pump air, which means that with regular cleaning, you not only prolong the life of the device, but also save energy.

⚠️ Warning: If your robot vacuum cleaner starts to hum, make unusual noises, or stops frequently during cleaning, the first reason to check is a clogged filter!

What filters are used in Xiaomi robot vacuum cleaners

Depending on the model, Xiaomi robot vacuum cleaners can have different types of filters, and here are the main ones:

To find out which filter is installed in your model, check the instructions or look at the markings inside the dust collector. HEPA-filters are usually specified in the class (H11, H12 or H13).

Step-by-step: how to clean the filter of the robot vacuum cleaner Xiaomi

The filter cleaning process depends on the type of filter, but the overall scheme is the same for most models, and we'll look at a universal algorithm that will work for Mi Robot, Dreame and Viomi.

1. Filter extraction

Open the dust collector lid (usually with a latch or a button) and you'll see a filter inside, which can be:

• 🔹 Round (in models of Mi Robot Vacuum) 1S, Dreame D9).
• 🔹 Rectangular (in Viomi) V3, Mi Robot Vacuum-Mop 2 Pro).
• 🔹 Mesh (pre-filter in budget models).

Carefully pull out the filter by pulling it up or pressing the locks. Don't use force -- if it doesn't respond, check if there are any additional attachments.

2.Dry cleaning (for all types of filters)

If the filter is not heavily contaminated, it can be cleaned without water:

1. Use a soft brush (such as a toothbrush) or a vacuum cleaner with a furniture nozzle to remove dust from the surface.
2. For hard-to-reach places, a balloon with compressed air is suitable (as for cleaning the keyboard).
3. Wipe the filter with a dry microfiber wipe.

3. Wet cleaning (only for washable filters)

HEPA And you can't wash carbon filters with water, you can just sanitize them or replace them, but sponge filters and mesh filters are washed like this:

1. Wash the filter under running water at a temperature not higher than 40°C.
2. Use a soap solution (ordinary soap or dishware) to remove fatty contaminants.
3. Do not rub with hard brushes – this can damage the structure of the filter.
4. So, rinse and rinse carefully (not twisting!).

💡

If the filter is heavily contaminated with fat (for example, after cleaning the kitchen), soak it for 10-15 minutes in warm water with the addition of vinegar (1 tbsp. spoon per liter of water), this will help dissolve the sticky deposits.

4. Drying and installation

This is the most important step, because you can't install a wet filter, because it's going to cause mold and bad smell.

• 🌞 Place the filter in a well-ventilated area (for example, on a balcony or windowsill).
• ⏳ Drying time: at least 24 hours HEPA and carbon filters, 12 hours for spongy.
• 🚫 Do not dry with a hair dryer or battery – high temperatures destroy the filter material.

After drying completely, install the filter back into the dust collector, making sure it sits tightly in place. Close the lid before you click.

💡

Even if the filter looks clean after drying, check for the smell. If there is a musty aroma, repeat the drying or replace the filter - this is a sign of the mold process that has begun.

How often to clean the filter: recommendations for different conditions

The frequency of filter cleaning depends on several factors: the intensity of the vacuum cleaner, the presence of pets, the type of coating in the house.

Note the signs that the filter needs urgent cleaning:

• 🔍 Robot vacuum cleaner became worse to collect garbage the first time.
• 🔊 Increased noise during operation (the engine is running at the limit).
• 🚨 Check Filter notification appears on the screen or in the application.
• 👃 There was an unpleasant smell after cleaning.

Common Filter Cleaning Mistakes and How to Avoid Them

Many users make the same mistakes that cause a filter or a robot vacuum to break, and the most common ones are:

⚠️ Note: If you use Mi Home or Dreamehome to control the vacuum cleaner, after cleaning the filter, reset the errors in the application. → Reset errors or restart the device.

• 🚿 Washing HEPA-The filter is water-damaged, and the filters can only be vacuumed or replaced.
• 🔥 Drying on a battery or under direct sunlight - leads to deformation of the material.
• 🧴 Use of aggressive detergents (domestos, chlorine) - they corrode the filter layer.
• 🔄 Installing a wet filter is the main cause of mold.
• 🛠️ Metal brushing – scratches the surface, reducing the efficiency of filtration.

Another common mistake is ignoring the prefilter, in many models (like Dreame). F9) In addition to the main filter, there is a mesh prefilter, which also needs to be cleaned at least 1 time a week. It traps large debris and protects the main filter from premature wear.

When it’s time to change the filter: signs of wear

Even with regular cleaning, the filter loses its properties over time, and here are signs that it should be replaced:

• 🔴 The filter has deformed, torn or lost its shape.
• 🔴 After cleaning, there is a persistent unpleasant smell.
• 🔴 Robot vacuum cleaner becomes worse collecting dust, despite clean filter.
• 🔴 Dark spots appeared on the filter (mold or fat deposits that are not washed off).

The service life of filters in Xiaomi robot vacuum cleaners:

• 🔹 HEPA-filters: 6-12 months (depending on the model).
• 🔹 Carbon filters: 3-6 months.
• 🔹 Mesh prefilters: 12+ months (with regular cleaning).

Replace the filter is simple: buy an original part (such as the Xiaomi Mi Robot Vacuum Filter for your model) or a compatible counterpart. Insert a new filter in the place of the old one, making sure it fits tightly.

💡

If you can't find the original filter, look for size- and class-compatible filters. For example, Mi Robot Vacuum-Mop 2 Pro is fine. HEPA-filter H12 from other brands, if its dimensions are the same.

Tips for caring for the robot vacuum cleaner Xiaomi: how to extend the life of the filter

To make the filter last longer, follow these guidelines:

• 🧹 Clean the dust collector after each cleaning – this will reduce the load on the filter.
• 🐾 Use special wool nozzles if there are animals in the house.
• 🚫 Don’t remove dust and sand – they clog the filter quickly.
• 🔋 Store the robot vacuum cleaner in a dry place – humidity reduces the life of the filter.
• 📱 Watch out for notifications in the app – modern models remind you of the need to clean.

If you use a wet-cleaning robot vacuum cleaner (such as Mi Robot Vacuum-Mop 2 Ultra), pay attention to cleaning your water tank and wipe. Wet cleaning without regular maintenance can lead to mold that then gets onto the filter.
