How to clean the vacuum cleaner Xiaomi Deerma: disassembly, washing and drying of all details

Why cleaning a Deerma vacuum cleaner is not just cleaning, but extending the life of the appliance

Xiaomi Deerma vacuum cleaners have gained popularity due to their combination of power, compactness and affordable price, but even the most reliable equipment requires regular maintenance – especially if it is a model with a cyclone filter and a removable dust container. Clogged filters reduce the suction capacity of the 40-60%, And the accumulated dirt in the turbine can lead to overheating of the engine, and in this article we will discuss how to clean Deerma correctly, so as not to damage the seals and not reduce the life of the equipment.

Many users limit themselves to emptying the container, but that's not enough. HEPA-Ignoring the cleaning of the turbine unit is the main cause of engine failure in 78% of Deerma vacuum cleaners older than 2 years (data from Xiaomi service centers for 2023). We have collected proven care methods that will help to avoid expensive repairs and maintain factory suction capacity.

What Deerma models require a special approach to cleaning

Xiaomi Deerma line includes both budget models for dry cleaning (VC20, VC15), and more advanced versions with aquafilter (CM19) or (VC30 Each modification has unique nodes that need to be cleaned differently:

• 🔹 Deerma VC20/VC15 — Classical cyclone vacuum cleaners with HEPA-They require a monthly flushing of all filters and lubrication of brush bearings.
• 🔹 Deerma CM19 — It is critical to monitor the condition of the water tank and membrane filter (they should not be washed with aggressive detergents!).
• 🔹 Deerma VC30 Pro is a flagship with wet cleaning function, and it has an additional water tank that needs to be disinfected every 3 months.
• 🔹 Deerma Mini (JD-01) — It's a compact hand vacuum cleaner, and it clogs up faster because it's a small container, so you'll have to clean it after every 5th use.

If you're not sure about your vacuum cleaner model, look at the labels on the bottom of your case or in your documents. Never use cleaning methods from one model to another, such as a washing vacuum cleaner. VC30 Pro cannot be disassembled as dry VC20, due to the risk of damaging the electronics of the wet unit.

Step-by-step: how to disassemble a vacuum cleaner for cleaning

Before you start cleaning, be sure to disconnect the vacuum cleaner from the mains and wait for the engine to cool down completely (if it worked).The disassembly of most Deerma models takes no more than 10 minutes, but requires care - many parts are attached to plastic latches that are easy to break.

Standard Disassembly Procedure (on the example of Deerma) VC20):

1. Remove the dust container by pressing the lock button on the side.
2. Extract. HEPA-filter (usually located behind the container or at the top of the housing).
3. Unscrew the turbine unit (if it is removable) - this may require a cross screwdriver.
4. Remove the main brush by pressing the locks on the sides.
5. To access the motor filter (if any), remove the back cover of the case.

Aquafilter models (CM19) extra:

• 💧 Disconnect the water tank and drain the remaining water.
• 🧼 Remove the membrane filter from the tank cover.
• ⚠️ Check the sealing ring on the tank - if it cracks, a replacement is required.

How to clean filters: HEPA, motor-cleaning

Filters are light vacuum cleaners, and their condition directly affects the suction power. Deerma models usually have:

• 🌀 Cyclone filter (plastic mesh in a container) – captures large debris.
• 🧹 HEPA-filter (usually) H11 or H12) — Detains microparticles and allergens.
• ⚙️ Motor filter (sponge or paper) – protects the engine from dust.

Cleaning instructions:

1. Cyclone filter: rinse under warm water (no detergents!), then dry for at least 12 hours. Don't rub with a hard brush - this will damage the microholes.
2. HEPA-filter: 🚿 Models. VC20/VC15: You can wash with water (maximum) 30°C) soft soap, dry 24 hour. 🔥 Models. CM19/VC30 Pro: only dry cleaning with a vacuum cleaner or soft brush!

Motor filter

⚠️ Attention: Never dry HEPA-The high temperature will warp the fibers, and the filter will lose up to 80 percent of its efficiency. The best way to do this is to leave it in the shade at room temperature.

💡

If after cleaning HEPA-filter vacuum cleaner became worse to suck, check its installation - even a slight distortion can violate the tightness of the system.

Cleaning the turbine unit and brushes: how not to break the bearings

The turbine unit and the brush are the dirtiest parts of the vacuum cleaner, where hair, thread and small debris accumulate, which winds on the shaft and blocks rotation, and ignoring the cleaning of the turbine is the main cause of engine overheating (statistically, 65% of Deerma breakdowns are associated with this).

Step-by-step:

1. Remove the brush from the body by pressing the side locks.
2. With scissors or tweezers, remove the hair from the shaft of the brush. Don't pull the threads with your hands, so you can damage the bristles.
3. To clean the turbine: 🔧 Models. VC20/VC15: unscrew 4 screw on the lower cover of the block, carefully remove the lid and remove the debris with a cotton swab. 🚫 Models. CM19/VC30 Pro: turbine unit indissoluble! Clean only outside with a soft brush.

Check the brush bearings – if they creak, apply 1 drop of silicone lubricant (not oil!).

⚠️ Warning: If you hear metal grinding from the turbine unit during the vacuum cleaner, stop using immediately! This is a sign that a solid object (such as a paper clip) has hit the blades.

For models with wet cleaning function (VC30 Pro) additionally:

• 💦 Wash the water tank with a warm acetic solution (1:10) to remove lime plaque.
• 🧴 Wipe the O-ring with silicone lubricant to prevent cracking.

How to Clean a Dust Container and Avoid Bad Smell

The dust container is a breeding ground for bacteria and a source of bad smell. Even if you regularly empty it, there's a sticky microparticle plaque on the walls that eventually starts to rot, and you have to wash the container after every 5th use, and if the vacuum cleaner is used to clean the animal's hair, after every 3rd.

Effective cleaning method:

1. Empty the container over the trash can, tapping it with your palm (do not shake it out! so the dust will fly around the room).
2. Soak the container in warm water with the addition: 🍋 Citric acid (2 tablespoons per 1 liter of water) – kills bacteria and eliminates the smell. 🧼 Means for washing dishes (without abrasives!) - removes greasy plaque.

Use a soft sponge or toothbrush to clean corners and cyclone channels.

Dry the container thoroughly before installing it back (humidity inside will lead to mold).

For disinfection and removal of persistent odor:

• 🧴 Wipe the walls of the container with a napkin moistened in a solution of chlorhexidine (0.05%).
• 🌿 Place a bag of baking soda or activated carbon inside for 12 hours.

💡

Never wash the container in the dishwasher! the high temperature will warp the plastic and it will lose its tightness.

Cleaning Mistakes That Kill Deerma Vacuum

Many users make critical errors that shorten the life of the vacuum cleaner in the 2-3 Here are the most common ones:

• 🚿 Washing HEPA-Hot water filter – temperature above 40°C destroys microfibers, and the filter stops trapping dust.
• 🧴 Use of aggressive detergents (such as Domestos) – they corrode seals and leave a chemical smell.
• 🔌 Cleaning the vacuum cleaner without disconnecting from the network - even in the off state, voltage may remain on the contacts.
• 🌬️ Drying filters on the battery or under the sun - leads to deformation and loss of filter properties.
• 🔧 Disassembly of the turbine unit without experience - the risk of damaging the blades or disrupting the shaft balancing.
• 🗑️ Using a vacuum cleaner without filters for a couple of days - dust will get into the engine and reduce its life by 5 times.

Another common problem is that you don't build properly after cleaning, like if you're not sealing a container or if you're crooked. HEPA-filter, vacuum cleaner will lose power and warm up:

• 🔒 Are all the locks on the container locked.
• 🌀 Is the cyclone filter correct (should be clicked).
• 🔄 Does the brush rotate freely (without jamming).

Care Tips: How to prolong the life of a Deerma vacuum cleaner

Regular cleaning is only part of the care. To ensure that the vacuum cleaner lasts longer, follow these recommendations:

• 📅 Keep a cleaning schedule: Container after each use. Filters 1 time per month (or more often if there are animals in the house); Turbine unit 1 time every 3 months; brush after every 10th use.
• 🔋 Watch the battery (in wireless models): Don't keep the vacuum cleaner discharged - charge up to 50% before long downtime. Avoid overheating the battery (don't leave it in the sun).
• 🧹 Use the brush correctly: Do not press the vacuum cleaner when cleaning - this increases the load on the bearings. For long hair, use a rubber roller nozzle (if you have it included).
• 🌡️ Control the temperature: If the vacuum cleaner case becomes hot, take a 30 minute break. Do not use the vacuum cleaner in rooms with temperatures above 35°C.

For models with aquafilter (CM19):

• 💧Always use distilled or filtered water to prevent scale buildup in the tank.
• 🧼After each use, rinse the water tank and leave it open to dry.

💡

If the vacuum cleaner is getting worse and all the filters are clean, check the tightness of the hose, and often the problem is microcracks or a loose connection.
