How to properly open and clean the filter in the robot vacuum cleaner Xiaomi: instructions for all models

Xiaomi’s robot vacuum cleaners are smart assistants that require regular maintenance, especially when it comes to filtration systems. A clogged filter not only reduces cleaning efficiency, but can also cause the engine to overheat or the turbine to break, but many users face difficulties in first removing the filter: unobvious latches, a tight fit, or the fear of breaking fragile parts.

In this article, we will discuss how to safely open the filter in popular Mi Robot Vacuum, Viomi and Dreame models, avoiding the typical errors. You will learn where the filter element is located, how to remove it correctly (including in models with non-standard design), and what to do if it is “stuck” from dust, and also how often and how to clean the filter to prolong the life of the vacuum cleaner.

Importantly, the procedure may vary depending on the generation of the device. For example, in Xiaomi Mi Robot Vacuum-Mop 2 Lite, the filter is hidden under the garbage container, and in Dreame D9, behind a separate lid, we covered all the current options.

Where is the filter in Xiaomi’s robot vacuum cleaner?

In most Xiaomi models, the filter is located in a dust collector (a garbage container), but its exact location depends on the design:

• 🔹 Classical models (Mi Robot Vacuum) 1/1S/2, Viomi V2/V3): filter is built into the top of the dust collector, under the lid with a latch.
• 🔹 Hybrid models (Mi Robot Vacuum-Mop) P/2 Pro, Dreame D9/D10): The filter can be placed in a separate compartment near or below the container.
• 🔹 New flagships (Xiaomi Robot Vacuum) X10+/S10): filter hidden behind a removable panel on the body, requires pressing a hidden button.

To avoid guessing, inspect the dust collector: usually the filter is visible through translucent plastic or marked with an icon. 🌬️. In models with wet cleaning function (mop), the filter is often separated from the water tank.

Exception: in some budget models (for example, Mi Robot Vacuum-Mop 2 Lite), the filter is combined with a sponge-dust collector and not removable, in which case the cleaning is carried out without removal, washing the entire unit under running water.

Step-by-step: how to open the filter in different models

The process of filter extraction varies depending on the design, and here is a universal algorithm based on the features of popular lines.

1. Preparation of the robot vacuum cleaner

Turn off the vacuum cleaner (press the power button for 3 seconds)

Remove the dust collector from the case

Clean the container from large debris (hair, thread, paper)

Prepare a soft brush and napkin-->

Before opening the filter, be sure to disconnect the vacuum cleaner from the charging station and remove the battery (if the model allows), which will prevent the turbine from accidentally turning on during cleaning, and check if there are sharp objects in the container (clips, nails) that could damage the filter when removed.

Filter extraction in classical models (Mi Robot 1/1S/2, Viomi V2/V3)

In these vacuum cleaners, the filter is inside the vacuum collector.

1. Press the release button of the container (usually located on the back of the case).
2. Remove the dust collector and turn it down.
3. Find a latch on the lid (often marked with an arrow or PUSH) and press it before you click.
4. Lift the lid and you will see a filter (a gray or white cylinder with a grid) below it.
5. Pull the filter up behind the plastic handle (if any) or gently tuck it on the side with your nail.

In the Viomi V3, the filter can stick to the body because of the accumulation of fat and dust. If it does not respond, do not pull forcefully, soak the cotton swab in alcohol and wipe the joints, then try again.

3. Hybrid models (Mi Robot Vacuum-Mop, Dreame) D9/D10)

In vacuum cleaners with floor washing function, the filter is often hidden deeper. D9:

1. Remove the dust collector by pressing the side latches.
2. Inside the container, find a black or gray round lid with grooved edges.
3. Turn the lid counterclockwise before clicking (in some models you need to press and pull up).
4. Under the lid is a cylinder-shaped filter or a cube, and pull it out by pulling the top.

In Mi Robot Vacuum-Mop 2 Pro, the filter can be combined with the same filter. HEPA-So, in this case, it's removed along with the plastic case by pressing the locks on the sides.

4. Filter in new models (Xiaomi Robot Vacuum) X10+/S10)

In Xiaomi's flagship vacuum cleaners, the filter is hidden behind a removable panel on the case.

1. Turn the vacuum cleaner upside down (on the back cover).
2. Find on the bottom of the case a rectangular panel with a filter icon.
3. Click on the hidden button (usually located on the right) and pull the panel over yourself.
4. Under the panel, you'll see a filter unit. Press the locks on the sides and take it out.

In these models, the filter is often equipped with a filling sensor. After removal, wait until the indicator on the vacuum cleaner case goes out (this will take 10-15 seconds).

How often and how often to clean the filter?

The manufacturer recommends cleaning the filter after every 3-5 cleanings (or every 1-2 weeks for daily use).

Use:

• 🧹 Soft brush (for example, toothbrush) for dry cleaning of dust.
• 💦 Warm water (not higher than 40)°C) for washing. Don't use detergents! They break down the filter fibres.
• 🌬️ Vacuum cleaner (in blowing mode) for drying after washing.
• ☀️ Ultraviolet lamp (optional) for disinfection for allergies.

⚠️ Attention: filters with HEPA-Coverage (for example, in Xiaomi) S10) You can't wash with water. You can only dry them or replace them with new ones. You can wash them with microscopic pores, and the filter stops holding up allergens.

Common errors in filter removal and cleaning

Even experienced users sometimes make mistakes that lead to breakdowns.

• 🚫 Pressing the dust collector hard can break the locks. Always check if there are any hidden latches.
• 🚫 Using sharp objects to tweak the filter, it scratches the body and breaks the leakage.
• 🚫 Drying the filter with a hair dryer at high temperature, the plastic can deform, and the filter will not fit tightly.
• 🚫 Install the inside out filter. It usually has a label on it. TOP or arrow indicating correct position.
• 🚫 Ignoring errors after cleaning. E3 or E5, filter installed incorrectly or damaged.

Another common problem is the loss of sealing gum when cleaning, and without it, dust will pass the filter, clogging the turbine, and always make sure that the gum is still there and not torn.

💡

If the vacuum cleaner starts to work louder after cleaning the filter, check if dust has entered the turbine. To do this, turn the robot over and blow the suction hole with compressed air (for example, a canister to clean the keyboard).

When should I change the filter to a new one?

The filter in Xiaomi’s robot vacuum cleaners is a consumable, and even with regular cleaning, it has to be replaced every 3-6 months (depending on the intensity of use), signs that the filter should be changed:

• 🔴 Smelling of dust even after cleaning.
• 🔴 Visible damage: ruptures, deformation, traces of mold.
• 🔴 Reduced suction force by more than 30% (checked by a sheet of paper test).
• 🔴 Mistakes. E5, E6 or E9 on display associated with the filtration system.
• 🔴 Black plaque on the filter that does not flush.

To replace, buy original filters for your model.

• For Mi Robot Vacuum 1/1S – art. ZNMS01WM.
• For Dreame D9 - Art. DM-FILTER-01.
• For Viomi V3 - art VIOMI-FIL-2021.

⚠️ Attention: cheap analogues often have a lower density of material and pass up to 40% of fine dust, which leads to accelerated wear of the turbine and engine.

What to do if the filter is lost or broken?

If the filter is damaged or lost, don't use the vacuum cleaner without it, it will cause dust to enter the engine and break down.

• 🛠️ Homemade filter: cut a circle out of a dense syntepon or nonwoven material (such as a medical mask) and insert it into the case. This will work for 1-2 cleanings, but will not replace the original.
• 📦 Ordering duplicate: original filters can be found on AliExpress, in Xiaomi branded stores or at official dealers.
• 🔧 Repair: If the filter just crumbles but the case is intact, try securing it inside the container with tape (temporary solution!).

The cost of the original filter is from 300 to 800 rubles depending on the model. For example, for Xiaomi Mi Robot Vacuum-Mop 2 Pro, a set of 2 filters will cost ~ 600 rubles.

💡

Never use a vacuum cleaner without a filter or with a damaged filter, which leads to dust entering the bearings of the turbine and its premature wear, the average cost of repairing the turbine is 3-5 thousand rubles, which is comparable to the price of a new vacuum cleaner.
