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

Xiaomi's robot vacuum cleaners are some of the most popular cleaning assistants, but their effectiveness depends on the condition of the filters. HEPA-The filter and pre-cleaning filter are clogged with dust, animal hair and small debris, which leads to a decrease in suction power, the appearance of an unpleasant smell and even turbine failure. In this article, we will analyze how to replace filters in the robot vacuum cleaners Xiaomi Mi Robot, Viomi, Dreame and other lines, so that the device lasts longer.

You will learn what tools you need, how often you need to change filters (and whether you can wash them), and you will receive step-by-step instructions with photos and videos. D9), If your vacuum cleaner is getting worse at collecting dust or making an uncharacteristic noise, it's probably the filters that are the problem.

What filters are used in Xiaomi robot vacuum cleaners

Most Xiaomi models have two types of filters:

• 🔹 Pre-cleaning filter (net or sponge) - traps large debris (hair, wool, threads). HEPA-filter.
• 🔹 HEPA-filter (fine cleaning) - captures fine dust, allergens and bacteria. It can be removable (for example, in Mi Robot Vacuum). 1S) or built into a dust collector (as in Viomi) V3).

Some models (e.g. DreameBot) D10 Plus) equipped with a three-level filtration system: in addition to HEPA, It has a carbon filter to neutralize the odors, and it's important not to confuse them when you replace them, because each type of filter has a different function and requires separate maintenance.

The manufacturer recommends that the change HEPA-The filter is used every 2-3 months (daily cleaning) and can be washed once every 1-2 weeks, but if it breaks or deforms, it should be replaced:

⚠️ Note: In models with automatic dust collector (for example, Xiaomi Mi Robot Vacuum) X10+) HEPA-The filter may not be located in the robot itself, but in the docking station, and replacing it requires a decomposition of the base, which we will discuss separately.

Signs that the filter needs to be replaced

It's not always easy to know if the filter is clogged, especially if the vacuum cleaner is working normally.

• 🌀 Reduced suction power – the robot worse collects garbage, leaves dust on carpets.
• 🔊 Increased noise – the turbine is running louder due to air resistance.
• 🤢 Unpleasant smell – the organic matter accumulated in the filter begins to rot.
• 🚨 Errors in the app – some models (like DreameBot) show a notification “Replace the filter".
• 🔋 Fast battery discharge – clogged filter makes the motor run at its limit, consuming more energy.

If you notice at least 2-3 features on the list, check the condition of the filters. In some cases, it is enough to wash them (if authorized by the manufacturer), but more often a complete replacement is required.

⚠️ Note: In models with a laser sensor (for example, Xiaomi Mi Robot Vacuum-Mop P), a clogged filter can lead to navigational malfunctions. Dust enters the sensor lenses, causing the robot to "get lost" or build incorrect maps of the premises.

Preparing for replacement: security tools and measures

Before you start the replacement, prepare everything you need:

• 🛠️ New filter – make sure it is suitable for your model (part number is usually listed in the manual or on the filter itself).
• 🧴 Soft brush or vacuum cleaner - to clean the vacuum collector from debris.
• 💧 Warm water and soap – if you plan to flush the pre-cleaning filter (if permitted).
• 🧻 Dry cloth or wipes - for cleaning internal surfaces.
• ⚡ Screwdriver (cross or flat) – may be needed for models with screw mounts (for example, Viomi) SE).

✅ Checklist before replacement:

⚠️ Warning: Never replace the filter immediately after cleaning - let the vacuum cleaner cool for 15-20 minutes. Z10 Pro) plastic latches may be deformed by heat, making disassembly more difficult.

If you use non-original filters, pay attention to their density. Cheap counterparts often let dust through, which negates all filtering, it is better to buy certified parts or filters from proven brands (for example, 360 or Ecovas).

Step-by-step instructions for replacing the filter

The replacement process differs depending on the model, but the overall scheme looks like this:

1. Dust collector recovery

Open the top cover of the robot (usually fixed by a latch or magnet) in vertically loaded models (e.g. Xiaomi Mi Robot Vacuum). 1S) The dust collector is removed by moving upwards in robots with a horizontal container (like in Viomi). V3) He needs to be pulled over.

📌 Important: In some models (e.g. Dreame) D9) The dust collector is blocked with a button – press it to release the container.

Access to filters

Inside the dust collector you will see:

• 🔄 Pre-cleaning filter - usually attached to latches or Velcros.
• 🌀 HEPA-filter - can be inserted into the groove or screwed.

Xiaomi Mi Robot Vacuum-Mop 2 Pro HEPA-The filter is hidden under the dust collector cover, and you need to carefully screw it up with a screwdriver. V3 The filter is removed with the plastic holder.

Removal of the old filter

Carefully pull the filter up or down (depending on the mounting). If it's stuck with dust, don't pull force, soak the edge with water and wait 1-2 minutes. In screw-mounted models (e.g., Roborock). S7) first unscrew the screw.

⚠️ In robots with automatic emptying (series Xiaomi) X10) HEPA-filter can be connected to the dust collector tube - do not pull it, so as not to tear it off.

Installation of a new filter

Before installing, check if the new filter is the same as the old one. Plug it into the groove before clicking or tighten the screw (if required). Make sure the filter sits tightly - if there are gaps left, dust will seep past.

In dual-filtered models (e.g. DreameBot) D10 Plus) the carbon filter is first installed, then HEPA. Don't confuse the order!

5. Assembly and inspection

Put the vacuum cleaner back together, make sure all the latches are fixed, turn on the vacuum cleaner and run the test cleaning, and if the robot is quieter and sucks up dust better, the replacement is successful.

🔍 How to check for leaks: Put your hand in the robot's exhaust hole (usually on the back) if you feel a heavy flow of air with dust, the filter is installed incorrectly or damaged.

Features of replacement in popular models

Some Xiaomi robot vacuum cleaners have unique filter designs, and let's look at the nuances for the most common series:

Xiaomi Mi Robot Vacuum 1/1S

In these models HEPA-The filter is rectangular and it's mounted on the latches inside the dust collector, and the main difficulty is the plastic guides, which are easy to break when you're not getting it properly, and we recommend that you press the top of the filter first to loosen the lock.

💡 Useful advice:

💡

Can I wash the filters instead of replacing them?

Xiaomi manufacturer does not officially recommend washing HEPA-filters, as water destroys microfibers, and the filter loses its properties. However, the pre-cleaning filter (net or sponge) can be washed with warm water and soap no more than 1 time every 2 weeks.

If you've decided to wash it, HEPA-filter:

1. Use cool water (hot water deforms the material).
2. Do not rub the filter with a hard brush - only a soft sponge.
3. Dry for at least 24 hours in a well-ventilated place (not on a battery!).
4. Do not use a dryer or other heating appliances.

⚠️ Attention: Washed HEPA-The filter loses up to 30-40% of its effectiveness after the first wash. If there are allergies or pets in the house, it is better not to take risks and put a new one.

🔬 How to check if the filter is damaged: Bring it to the light. If there are large pores through the material, the filter no longer performs its function and must be replaced.

Frequent Filter Replacement Mistakes and How to Avoid Them

Even experienced users sometimes make mistakes that lead to a vacuum cleaner breakdown.

• 🔧 Use of force in filter removal → Solution: If the filter doesn't come out, moisten the edge with water or use a plastic pickup.
• 🌀 Incorrect installation of the filter (not in the direction of the air flow) → Solution: the filter usually has an arrow pointing the direction.
• 💦 Washing HEPA-detergent → Solution: use only water.
• 🔌 Forget to turn off the vacuum cleaner from the socket → Solution: always turn off power before disassembly.
