Replacement of the filter in the robot vacuum cleaner Xiaomi: when, how and which to choose

Xiaomi’s robot vacuum cleaners are smart assistants that save you time and keep your home clean. However, like any appliance, they require regular maintenance. One of the key elements affecting cleaning quality and household health is the HEPA- filter. Over time, it gets clogged with dust, loses bandwidth, and stops trapping small particles, allergens, and bacteria.

In this article, we will learn how to change the filter in the Xiaomi Mi Robot Vacuum, Viomi, Dreame and other models based on the Mi Home platform. You will learn when it is time to replace, which filters are suitable for your model, and how to avoid errors that reduce the life of the equipment.

Why it is important to change the filter in the robot vacuum cleaner

Many users underestimate the role of the filter in the robot vacuum cleaner, believing that the brushes and the turbine are the main thing, but the HEPA- filter has several critical functions:

• 🧹 Detains up to 99.97% of particles up to 0.3 μm in size, which are pollen, mold spores, animal hair, and even viruses.
• 🌀 Prevents turbine clogging – if the filter is clogged, the engine is overloaded, leading to overheating and breakdowns.
• 🚫 Blocks the spread of dust back into the air – without a filter, the vacuum cleaner simply “drives” debris around the room.
• 📉 Reduces power consumption – a clean filter provides optimal airflow, saving battery life.

Studies have shown that a clogged filter increases the load on a robot vacuum cleaner’s engine by 30-40%, which reduces its life by 15-20%, and if you or your loved ones suffer from allergies or asthma, untimely replacement of the filter can worsen symptoms.

⚠️ Warning: If a specific dusty smell appears after cleaning the room, it's a sure sign that the filter has been around for a long time and has become a breeding ground for bacteria, and in such cases, the replacement should be done immediately, even if the deadline is not yet right.

How often to change the filter: Xiaomi recommendations

Xiaomi manufacturer in official instructions indicates that the HEPA- filter in robot vacuum cleaners should be replaced every 2-ZXZ-3 month under intensive use (daily cleaning) or once in 4-6 months in moderate mode. However, these figures are conditional - the real term depends on several factors:

• 🏡 Room area and pollution levels – in homes with animals, carpets or building dust, the filter clogs faster.
• 🌿 Type of debris – fine dust (such as from drywall) clogs the filter more than large debris.
• 🔋 Cleaning mode – at maximum suction power, the filter wears out faster.
• 🌡️ Indoor humidity – In humid climates, the filter may be covered with mold, which requires more frequent replacement.

To determine if it is time to change the filter, pay attention to the following signs:

What filters are suitable for Xiaomi robot vacuum cleaners

Not all filters are the same, they differ in material, filtering class and model compatibility. Xiaomi’s robot vacuum cleaners use two main types:

1. The original HEPA filters from Xiaomi (ZMJGJ01YM, ZMJGJ02YM, etc.) guarantee maximum efficiency, but are more expensive.
2. Universal filters from third-party manufacturers (for example, Roborock, Ecovacs) are cheaper, but may yield as a filter.

The table below provides a list of compatible filters for popular models:

When choosing a filter, pay attention to the filtering class:

• 🔹 HEPA H11 — retains 95% of particles of 0.3 μm size (standard for most robot vacuum cleaners).
• 🔹 HEPA H12/H13 is the efficiency of 99,5–99,95% (used in premium models, for example, the Roborock S8 Pro Ultra).

💡

Before buying a filter, check its compatibility with your model in the official Mi Home app ("Accessions").Some universal filters may not fit in size or shape, even if listed as compatible.

Step-by-step: how to change the filter in the robot vacuum cleaner Xiaomi

Replacing the filter is a simple procedure that takes no more than 5 minutes, but there are a few nuances that can help avoid errors.

1. Preparation of the robot vacuum cleaner

Before replacing the filter:

• ⚡ Disconnect the vacuum cleaner from the charging station and turn it off with the power button.
• 🧹 Make sure the trash container is empty - take it out and clean it.
• 🧼 Wipe the vacuum cleaner body with a wet wipe to avoid getting dust into the new filter.

2. Removal of the old filter

In most Xiaomi models, the filter is inside the dust collector.

1. Click on the latch (usually located on the top or side of the container).
2. Take the filter out carefully by pulling it up. Don't use force -- if it doesn't respond, check if there are any additional locks.
3. Check the filter: if it is gray or black, covered with a layer of dust or deformed – it is time to change it.

Installation of a new filter

When installing a new filter, be sure to:

• 🔄 Correct orientation – the filter usually has a label (arrow or TOP) that should look upwards.
• 🔇 Adjacent density – the filter must enter without gaps, otherwise dust will seep past.
• 🧼 Clean seat - wipe it with a dry napkin before installation.

4. Test run

After the filter has been replaced:

1. Turn on the vacuum cleaner and put it on the charger.
2. Run a test cleaning in Spot Cleaning mode.
3. Check if there is any extraneous noise or vibration, which may indicate that the filter is not installed correctly.

⚠️ Warning: If the vacuum cleaner is getting worse after the filter is replaced, check if the air channel is blocked. In some models (e.g. Xiaomi Mi Robot Vacuum-Mop 2 Pro), the filter can block the air flow sensor if installed incorrectly.

Common Filter Replacement Mistakes and How to Avoid Them

Even a simple procedure like changing a filter can go wrong if you don't take into account some of the details, and here are the most common mistakes and their consequences:

• 🔄 Upside-down filter installation → reduced filtration efficiency, dust penetrates the motor.
• 🧴 The use of detergents in filter cleaning → the structure of the HEPA- material is destroyed, the filter stops trapping small particles.
• 🗑️ Replace the filter without cleaning the dust collector → the new filter will quickly become clogged with debris.
• ⏳ Ignoring replacement time → increased engine wear, deterioration of cleaning quality.

One of the most dangerous mistakes is to try to flush the HEPA- filter with water. Unlike the net filters in conventional vacuum cleaners, the HEPA- filters are made of a special fibrous material that loses its properties when wet. If the filter is heavily contaminated before the replacement period, it can be neatly cleaned with a vacuum cleaner at minimum power or a soft brush, but not with water!

💡

The HEPA- filter is a consumable, not a reusable part, and any "savings" on replacing it lead to accelerated wear and tear of the robot vacuum cleaner and deteriorating air quality in the home.

How to extend the life of the filter and save on expenses

Although a filter is a consumable, there are several ways to reduce the frequency of its replacement and save:

• 🧹 Clean the dust collector regularly - after each cleaning, shake it out and wipe it with a wet wipe.
• 🌬️ Use a prefilter – some models (e.g. Roborock S7) support the installation of an additional grid that traps large debris.
• 📅 Plan cleaning – avoid running the vacuum cleaner at maximum power every day if not necessary.
• 🛒 Buying filter sets in bulk is cheaper than buying one at a time, for example, a set of 5 filters for Xiaomi Mi Robot costs 30-40% less.

Another way to save money is to use third-party rechargeable filters (e.g., iClebo or Neato) that cost more than one-time filters, but can be washed and reused up to 5-10 times, but their effectiveness after washing is reduced by 10-15%, so this option is not suitable for allergic people.

💡

If you often remove building dust or animal wool, install a reminder to check the filter every 1.5 months in the Mi Home app to help avoid sudden breakdowns.
