Cleaning the vacuum cleaner Xiaomi Dreame V11: disassembly, filter washing and brush care

Xiaomi Dreame V11

30–50%

90% of breakdowns

Many users are afraid to disassemble the equipment on their own, for fear of breaking fragile plastic latches or disrupting the tightness of the system. V11 All removable parts are designed for manual cleaning — the manufacturer even mentions this in the official instructions, but does not disclose the nuances. In this article, you will find a detailed analysis of each step: from washing to washing. HEPA-filter before cleaning the ducts, as well as a list of errors that lead to the breakdown of the vacuum cleaner after cleaning".

We tested all the methods on three Dreame copies. V11 (And they've also included the automatic cord winder version, and they've identified key things that even service centers ignore, like why you can't dry filters with a hair dryer or how to properly lubricate the turbine bearings so you don't overheat the engine. If your vacuum cleaner becomes worse sucking garbage or makes an uncharacteristic whistle - most likely, the problem is solved by a 20-minute cleaning without buying spare parts.

Preparation for cleaning: what you need and safety measures

Before you start disassembling, make sure the vacuum cleaner is completely offline and the battery is fully off (if you have a wireless version of Dreame). V11 Pro) removed. Even when switched off, the capacitors can retain charge, which will result in an electric shock when in contact with the control board.

You will need:

• 🧼 Warm water (not above 40)°C) and soft detergent (e.g. for baby bottles) - aggressive chemistry destroys micropores HEPA-filter.
• 🧽 Toothbrush with soft bristles for cleaning turbines and ducts.
• 🔧 Flat screwdriver or plastic mediator – to fit the latches of the case (metal tools scratch plastic).
• 🧴 Silicone lubricant (e.g, WD-40 Specialist) for turbine bearings.
• 📦 Vacuum cleaner or compressed air balloon - for blowing dust out of hard-to-reach places.

Pay attention to three critical points:

⚠️ Warning: Never wash a motor unit under running water - even if it seems airtight.In Dreame V11 sealing gums lose elasticity over time, and moisture penetrates to the electronics, causing corrosion of contacts.

If you're cleaning the vacuum cleaner for the first time, take a picture of all the parts before disassembling, especially the gaskets and seals, which cause the suction power to be lost if installed incorrectly. Also check if the main filter has expired: Dreame. V11 It is designed for 150 hours of work (about 6-8 months with cleaning 2 times a week).

💡

If you lose your fasteners or latches, don't use screws of a different diameter, because it can damage the thread in the plastic case. You can order original parts from the articles in the vacuum cleaner manual.

Disassembly of the vacuum cleaner: step-by-step instructions with a photo

Let's start with the removal of removable elements. V11 All key nodes are attached to latches, but some models (for example, V11 Absolute) have additional screws under rubber plugs.

Disassembly order:

1. Take the dust container off, press the hold button on the handle and pull the container up, and inside it is a cyclone filter, which you have to remove.
2. Disconnect the pipe, turn it counterclockwise and pull it out of the case, and the junction often accumulates debris.
3. Remove the brush: press the red button on the head and remove the nozzle. V11 a turbine brush with lighting is used - we will consider its cleaning separately.
4. Remove the back cover: put a screwdriver in the joint (usually there is a small notch) under the cover is hidden. HEPA-filter and engine compartment.

Now we turn to a deep discussion:

• 🔍 Motor unit: unscrew 4 screws (usually under a cross screwdriver) and gently lift the top of the body. Don't pull too much - wires are connected to the control board.
• 🌀 Turbine: In models with automatic cord winding, the turbine is mounted on two latches. In manual versions, it must be scrolled counterclockwise.
• 🔋 Battery (for wireless versions): unplug the power connector before removing. Don't touch the contacts with your bare hands - static electricity can damage the controller.

If you notice black traces of carbon monoxide on the motor contacts or the board, it's a sign of overheating, and then you can't do it, you'll need a diagnostic service.

Cleaning filters: HEPA, cyclone

Filters are light vacuum cleaners, and their condition directly affects the suction power. V11 A three-stage filtration system is used:

1. Cyclone filter (separator) - captures large debris.
2. HEPA-filter - retains particles up to 0.3 μm (dust, allergens).
3. Motor filter (sponge) - protects the engine from fine dust.

How to clean each type:

Pay special attention HEPA-Unlike cheap vacuum cleaners, Dreame. V11 class filter H12, which can be washed, but with reservations:

• 🚫 Don’t rub it with a hard brush – it disrupts the structure of microfibers.
• 🌡️ Dry only naturally (not on a battery or under the sun) – high temperature deforms the frame.
• 🕒 Drying time: at least 24 hours. Wet filter allows dust to pass through and can become a breeding ground for mold.

⚠️ Note: If after cleaning HEPA-The vacuum cleaner smells damp, so you didn't dry it enough or you used an aggressive detergent, so rinse the filter with clean water and dry it again.

Turbine and brush cleaning: why they clog and how to fix it

Turbine brush with lighting - pride Dreame V11, But it's also the most vulnerable element, and the hair, the threads and the fur of the animals are wound onto the shaft, blocking the rotation, and if you don't brush regularly, it leads to the fact that you don't brush regularly:

• 🔥 Overheating of the engine (the turbine creates additional load).
• 🔊 Increased noise (squeaking or vibration when working).
• 🐌 Reduced suction power by 40-60%.

How to clean and clean your brush:

1. Remove the brush from the vacuum cleaner by pressing the red button.
2. Turn it over and unscrew the 3 screws on the bottom cover (use a cross screwdriver).
3. Remove the blade shaft. Wrap your hair and threads on your finger, then rinse the parts in soapy water.
4. Lubricate the bearings of the shaft with silicone lubrication (1-2 drops for each).
5. Collect the brush in reverse order, making sure the blades rotate freely.

For a turbine in a vacuum handle (if your model is equipped with one), use compressed air or a soft brush. Don't try to disassemble the turbine yourself - its blades are balanced in the factory, and improper assembly will lead to vibration.

If the brush is still rotating with difficulty after cleaning, check:

• 🔍 Condition of the drive belt (in mechanically transmitted models).
• 🛠️ Luft shaft - if it dangles, bearings are worn out.
• 💡 Backlight contacts – oxidation can block power.

💡

Cleaning brush and turbines should be carried out at least 1 time a month if there are pets in the house. the coat of cats and dogs is wound on the shaft 5 times faster than human hair.

Cleaning of ducts and engine compartment

Even if the filters are clean, clogged ducts can reduce vacuum power by 25 to 30 percent. V11 The three most vulnerable areas:

1. Pipe - dust and small debris accumulate in the bends.
2. The connecting hose (between the container and the motor).
3. Ventilation holes on the body (they are closed by a motor filter).

How to clean:

• 🌀 Pipe: Use a long brush or a flexible cable, and in extreme cases, you can run a rope with a knot at the end through it.
• 🔍 Hose: disconnect it from the engine unit and rinse it under a stream of water. If the clog is heavy, soak the hose in warm water with vinegar (1:1) for 30 minutes.
• 💨 Vent openings: blow them with compressed air or vacuum in blow mode. Do not use sharp objects - this will damage the fan blades.

For the engine compartment, act carefully:

1. Remove the top cover (as described in the "Shootdown" section).
2. Remove dust from the fan blades with a soft brush.
3. Blow the compartment with compressed air, holding the balloon at a distance of 10-15 cm.
4. Check the contacts of the control board - if they are oxidized, wipe with alcohol.

⚠️ Warning: If you notice oily spots in the engine compartment, it's a sign of wear on the shaft bearings, and you can't do that, you need to replace the parts.

After cleaning the ducts, check the vacuum cleaner for leakage. Put your hand to the suction hole at maximum power - if you feel the air flow from the side, the sealing gums are worn out and need to be replaced.

Vacuum assembly and test inspection

To assemble Dreame V11 You need to be in reverse order, following the three rules:

1. Check the seals: the gums on the container and the filters should fit tightly. If they are deformed, replace them.
2. Hold all the latches to the click, and the unpressed mounts will cause vibrations when you're working.
3. Connect the battery last (for wireless models).

Test after assembly:

• 🔋 Charging: If the vacuum cleaner does not turn on, check the contacts of the battery.
• 🌀 Suction power: bring your hand to the slit - the airflow should be smooth, without pulsations.
• 🔊 Noise: Normal level for Dreame V11 — 70–75 dB Whistling or grinding indicates a turbine malfunction.
• 💡 Brush lighting: if it doesn't work, check the wire connection.

If after cleaning the vacuum cleaner began to work worse, the probable reasons:

💡

After the first cleaning, mark the date on the vacuum cleaner case with a marker, which will help track service intervals and prevent blockages.

Frequent Mistakes and How to Avoid Them

Even experienced users make mistakes when cleaning Dreame V11, And that's what causes breakdowns. TOP-5 most dangerous:

1. Use of aggressive detergents

Many people wash filters with Domestos or White, thinking it would kill bacteria. HEPA-It's a filter and it leaves toxic fumes that then get into the air when cleaning:

• 🧼 Baby soap or dishware.
• 🍋 Citric acid (1 tsp per liter of water) – kills bacteria and eliminates odors.

2. drying of filters with a hair dryer or on a battery

High temperature deforms the plastic frame HEPA-The right way to do this is to dry it at room temperature for 24 hours, turning it over periodically.

3. Cleaning of the turbine with sharp objects

Attempting to remove hair with a knife or scissors scratches the shaft and blades, which leads to imbalance.

• 🪥 Plastic knife (for example, for oil).
• 🧵 String or line - put it under the coiled hair and pull.

Ignoring the motor filter

Many people just clean. HEPA, Forgetting the sponge under the motor: a clogged motor filter causes the heat protection to overheat and go off (the vacuum cleaner shuts down after 5-10 minutes of operation).

5. Incorrect assembly of ducts

If you don't plug the pipe or the hose in, you get leaks of air that cause the vacuum cleaner to lose up to 40 percent of its power. Always check the connections for leaks.
