Replacement of the filter in the robot vacuum cleaner Xiaomi: instructions for all models

Xiaomi’s robot vacuum cleaners have become an integral part of the smart home, but their effectiveness depends on the condition of the filters. A dust-filled filter not only reduces suction power, but can also lead to engine overheating or sensor breakdowns. In this article, we will discuss how to replace the filter in popular models, from the budget Mi Robot Vacuum-Mop to the flagship DreameBot and Viomi V3.

The replacement procedure seems simple, but there are nuances, from choosing the original or analog filter to installing it correctly to avoid errors like Error 10 (clogging system).

What filters are used in Xiaomi robot vacuum cleaners

In the line of Xiaomi there are three types of filters, differing in design and materials:

• 🔹 HEPA- filters — installed in most models (e.g., Mi Robot Vacuum-Mop 2 Lite) — trap up to 99.97% of particles up to 0.3 μm, including pollen and bacteria, typically with a plastic case with sealing gum.
• 🔹 Coal filters are found in premium series (DreameBot D9, Viomi V2 Pro) and absorb odors from activated charcoal in addition to dust.
• 🔹 Grid filters are the simplest option for low-end models (Mi Robot Vacuum 1S) to protect the engine from large debris, but do not filter fine dust.

Important: filters from different models are not interchangeable. For example, the filter from Xiaomi Mi Robot Vacuum-Mop P will not be suitable for the DreameBot Z10 Pro, even if they look similar. Always check compatibility with the model of the robot and the filter article (indicated on the package or in the documentation).

The manufacturer recommends using original filters, but there are quality analogues on the market from brands Bakeey, Baseus or Xiaomi Eco-System. The main thing is to avoid cheap fakes without certification, which can pass dust or poorly fixed in the case.

When and how often to change the filter

The service life of the filter depends on several factors:

The critical sign of wear is the appearance of Error 10 (system lock due to clogging), in which case the filter must be replaced immediately, otherwise the robot may fail.

Xiaomi's instructions indicate the average filter life is 6 months, but this value is only relevant for ideal conditions. In practice, when used actively, the filter loses its effectiveness after 2-3 months. To check its condition, take out the filter and illuminate with a flashlight: if the light does not pass through the material, it is time to change.

💡

If the robot has started to return to base more often with an Error 5 error (low charge), check the filter - a clogged system increases the load on the engine and consumes the battery faster.

Step-by-step instructions for replacing the filter

The filter replacement process is the same for most Xiaomi models, but there are nuances depending on the design. We will look at the universal algorithm with the example of Mi Robot Vacuum-Mop 2 Pro.

Step 1: Remove the old filter

1. Turn the robot vacuum cleaner lid down on a flat surface. Make sure there are no small parts nearby that can fall inwards.

2. Press the latch of the dust container (usually located on the side or top) and remove it. In some models (for example, DreameBot D9), the container is fixed by a magnet - pull it on yourself with force.

3 Open the filter lid. Most of the time, it's attached to plastic latches. Carefully put your nail or plastic card on it so you don't break it.

Step 2: Clean and install a new filter

1. Take out the old filter and inspect it. If there is dust or debris on the container case, remove them with a soft brush or vacuum cleaner at minimum power.

2. Insert a new filter by matching it with the slots in the container. Make sure that the sealing gum (if any) fits tightly to the edges. Don't press the filter by force - it should come in easily.

3. Close the container lid before you click. Make sure the latches are fixed evenly throughout the perimeter.

Step 3: Checking the performance

1. Install the container back into the robot and turn it on. Run a test cleaning in Spot Cleaning mode.

2. Check if there are any extraneous noises or errors on the screen. If the robot gives you an Error 10, then the filter is installed incorrectly or does not fit the model.

In models with a LDS- sensor (laser scanner), after changing the filter, calibration may be required. To do this, restart the robot by holding the power button 10 for seconds.

Mistakes in Replacing the Filter and How to Avoid Them

Even experienced users sometimes make mistakes that lead to breakdowns.

• ❌ Using non-original filters without certification, cheap ones can not fit tightly, allowing dust to enter the engine, which leads to an error Error 9 (fan clogging).
• ❌ Up-foot filter setting. Most filters have a tag TOP or an arrow indicating the correct position, and if you ignore it, the filtering efficiency drops by 30 to 40 percent.
• ❌ A container cleaning skip, if you don't remove the dust from the case before you install the new filter, it will immediately clog it, reducing the lifespan to 1-2 weeks.
• ❌ Using a filter after wet cleaning. In models with floorwashing (e.g., Viomi V3), the filter can become damp, and it needs to be dried 24 hours before reuse.

Pay special attention to carbon filter models, which you can't wash with water, which destroys the carbon layer, and if the filter is wet, it needs to be replaced, even if it looks clean.

⚠️ Warning: In the DreameBot D9/D10 series, the filter is integrated with the fan, and if installed improperly, the blade can break, requiring expensive repairs. Always watch for grooves to fit!

How to prolong the life of the filter: tips for care

The average filter life can be increased by 20-30% if you follow the following simple recommendations:

• 🧹 Clean the garbage container after each cleaning. Use a soft brush or vacuum. Don't wash the container under running water, it warps the plastic.
• 🌬️ Blow the filter with compressed air 1 time every 2 weeks, this will be suitable for a can of cleaning equipment or compressor at minimum power. Keep the cylinder at a distance of 10 cm so as not to damage the material.
• 🚫 Avoid cleaning construction dust or sand. Large particles quickly clog the filter. Use low-suction modes for this.
• ☀️ Store spare filters in a dry place. Humidity greater than 60% can warp the coal or HEPA- layer.

For models with wet cleaning function (Viomi V3, DreameBot W10), after each cleaning, wipe the filter body with a dry wipe.

💡

Cleaning the container regularly and purging the filter with compressed air increase its life by 25-30%, saving you money on replacement.

If you use a robot vacuum cleaner in a house with animals, consider buying a washable filter (e.g. from Bakeey) that can be washed with water 1 time per month, but after each wash requires drying within 24 hours.

Comparison of original and analog filters

Many users are wondering whether to overpay for the original filters Xiaomi, or the analogues are not inferior?

Our verdict: original filters justify their price if you use a robot vacuum cleaner intensively (daily or in the house with animals). For rare cleaning, high-quality analogues from Bakeey or Baseus are also suitable. Cheap no-name filters are not recommended to buy - they not only filter worse, but can damage the engine due to poor fixation.

When buying an analogue, pay attention to:

• 🔍 Availability of a HEPA certificate (to be indicated on the package).
• 📏 A precise match of size and shape to the original.
• 🧲 The quality of the sealing gum (it must be elastic, without cracks).

Where to buy filters for the robot vacuum cleaner Xiaomi

Original filters and proven analogues can be purchased in the following places:

• 🛒 Official Xiaomi Store (mi.com/ru) – guaranteed original parts, but often more expensive by 20–30%.
• 🛒 Marketplace (Wildberries, Ozon, Yandex Market) — a large selection of peers with reviews. Look for sellers with a rating above 4.8.
• 🛒 AliExpress is cheaper, but it's a risk of getting faked. Check reviews and photos of real customers.
• 🛒 Xiaomi Service Centers – sometimes sell discounted filters when replaced under warranty.

When buying on AliExpress, pay attention to the following points:

• 📦 The description should indicate compatibility with your model (e.g., "For Xiaomi Mi Robot Vacuum-Mop 2 Pro").
• 📸 The seller must post a photo of the real product, not stock pictures.
• ⭐ Store rating is not lower than 95% positive reviews.

Average price of filters (July 2026):

• Original HEPA- filter: 800–1200 ₽.
• Analogue from Bakeey/Baseus: 300–600 ₽.
• Coal filter for DreameBot: 1200–1800 ₽.

⚠️ Warning: AliExpress often sells "universal" filters that supposedly fit all models. That's a hoax -- filters like this don't provide tightness and can damage the robot. Always check for article compatibility!
