Why cleaning Xiaomi vacuum cleaner is not just cleaning, but the key to its long work
Xiaomi’s wireless vertical vacuum cleaners (Mi Handheld Vacuum, Dreame, Deerma, and others) have become indispensable household cleaners because of their compactness and power, but what few people know is that 80 percent of these devices are due to improper maintenance — clogged filters, overheating engines, and worn-out brushes. Regular cleaning not only maintains suction power, but also prevents costly repairs.
In this article, we will analyze all the critical areas of the vacuum cleaner that require attention: from a removable dust container to a vacuum cleaner. HEPA-You will learn what errors in cleaning lead to loss of power on the 30-50% through 3 months of operation, and how to avoid typical problems - for example, when the vacuum cleaner begins to "spit" back with dust or makes a whistling sound.
Important: The manual is suitable for most Xiaomi models (including the Mi Vacuum Cleaner G10, Dreame V11, Deerma T20 and its counterparts), but some nuances may differ.
1.Preparation for cleaning: what you need and how to avoid mistakes
Before you disassemble the vacuum cleaner, prepare the workspace and tools, which will speed up the process and protect the equipment from damage.
- 🧹 Soft brush (a tooth or brush for makeup is suitable) - for cleaning filters and hard-to-reach places.
- 💦 Warm water (not hot!) and neutral detergent (e.g. dishwashing liquid).
- 🧻 Microfiber wipe or paper towels for drying.
- 🔧 Screwdriver (if you need disassembly of nozzles) - usually a cross or hexagon.
- 🧲 Vacuum cleaner or hair dryer (at minimum power) – to remove dust from the cracks.
Critical error: many users start cleaning without turning off the battery. This is dangerous! Even when the contacts are off, they can close when moisture enters. Always remove the battery (if the model allows), or at least turn off the vacuum cleaner from charging 2 hours before cleaning.
⚠️ Warning: Never use harsh chemicals (acetone, gasoline, alcohol) to clean filters. HEPA-filter and reduce its service life in 2-3 once.
2. Cleaning of the container for dust and garbage: step-by-step instructions
The container is the heart of the vacuum cleaner that clogs the fastest, and if you don't clean it, the suction power drops by 40 percent, and the engine runs overloaded. Here's how to do it right:
- Unplug the container: Press the unlock button (usually located on the handle or case) and remove the container.
- Remove the garbage: shake the contents into the urn. For fine dust, use a second vacuum cleaner brush (if any) or a soft brush.
- Rinse the container: fill it with warm water with a drop of detergent, cover it and shake it. Use a cotton swab for persistent contaminants.
- Dry: Leave the container to dry in air for at least 12 hours (humidity inside leads to mold).
Pay special attention to the sealing gum on the container lid. If it is contaminated, the vacuum cleaner will lose its tightness and "blow" the dust back, wipe the gum with a wet wipe and lubricate it with silicone lubrication (for example, WD-40 Specialist).
☑️ Cleaning the dust container
The secret from the service centers is that if the container makes a whistling sound when operating, it is a sign of a blockage in the duct, blow the vacuum cleaner tube with a hairdryer (cold mode!) or clean it with a flexible cable.
3. Cleaning of filters: HEPA, motor and pre-filtration
Filters in Xiaomi vacuum cleaners are the most vulnerable element.clogged HEPA-The filter not only reduces power, but also increases the load on the engine, which leads to overheating. Most models have 3 types of filters:
| Type of filter | Location. | Frequency of cleaning | Signs of pollution |
|---|---|---|---|
| Preliminary (spongy) | In front of the engine, in the container. | After every 3-5 cleaning | Visible dust, power reduction |
| HEPA-filter | Behind the engine, under the lid. | Every 1-2 months | Smell of fire, dust on the way out |
| Motor (metal mesh) | Next to the engine | Every 6 months | Overheating, automatic shutdown |
How to clean HEPA-filter (the most important step):
- Remove the filter (usually it is attached to latches or screws).
- Tap them carefully on a hard surface to remove the large dust.
- Rinse under running water (temperature no higher than 40°C!) without detergents. Direct the jet from the back (where the air comes from).
- Dry for at least 24 hours in an upright position (not on the battery!).
⚠️ Note: If after cleaning HEPA-The filter has deformed or broken, and it needs to be replaced, and the filter that's damaged causes the microparticles of dust to enter the engine, which reduces the engine's lifespan. 30-50%.
💡
To extend life HEPA-before each cleaning, shake out the dust container - this reduces the load on the filtration.
4. Cleaning of turbine nozzle and main brush
The turbine nozzle (also known as the motor brush) is the dirtiest part of the vacuum cleaner, and the animal's hair, thread and fur are wound onto the shaft, blocking rotation. If you don't clean it regularly, the nozzle motor will burn through the shaft. 6-12 months.
Cleaning instructions:
- Remove the nozzle from the vacuum cleaner tube (usually there is a lock button).
- Open the lid (a screwdriver or coin may be required to crack the clamps).
- Remove the wound hair: 🧶 For short hair: Use scissors or pliers. 🐕 For the wool of animals: will help sticky roller or scotch.
Rinse the blades.
Grease the bearings

For models with laser illumination (for example, Dreame V12), additionally wipe the lens with a dry napkin - the dust on it reduces the brightness of the beam.

5. Battery care: how to extend battery life
Lithium-ion batteries in Xiaomi vacuum cleaners lose up to 20% of their capacity per year if they do not comply with the rules of operation.
- 🔋 Constantly being on charge (overcharging accelerates degradation).
- 🌡️ Storage at temperatures above 30°C or below 0°C.
- 🔌 Use of non-original chargers.
How to charge correctly:
- Charge the battery to 80-90% for everyday use (a full charge is required every 2-3 months for calibration).
- Do not leave the vacuum cleaner on charging for more than 4 hours after reaching 100%.
- Store the battery at 40-60% charge if you do not use the vacuum cleaner for more than a month.
If the vacuum cleaner is running out quickly, check the battery status through the Mi Home app (for supported models). For example, Dreame V11 has a Battery Health feature that shows wear and tear as a percentage.
⚠️ Warning: If the battery is swelling or deformed, you can't keep using it! This is a risk of fire. Immediately remove the battery and dispose of it at the point of reception.
6. Prevention and storage: how to avoid breakdowns
Even the most careful care will not save the vacuum cleaner if you violate the rules of storage and operation. Here are 5 key recommendations from service engineers:
- 🏠 Keep the vacuum cleaner in a dry place with a temperature 10-25°C. Higher humidity 60% corrosion of contacts.
- 🔌 Don't twist the charging cord - it damages the veins. Use the original coil or hang it loosely.
- 🚫 Do not suck up liquids, sand or construction debris – it instantly kills the engine and filters.
- 🔄 Alternate nozzles: the constant use of one brush leads to its premature wear.
- 📅 Keep a cleaning diary: Write down the dates of filter cleaning and consumable replacement (e.g., in phone notes).
A hidden problem: many users are unaware that Xiaomi vacuum cleaners have overload protection. If the engine overheats (for example, due to a clogged filter), the equipment automatically shuts down. But frequent protections reduce the engine life. To avoid this, watch the blockage indicator (if your model has one) or listen to the change in the sound of the work.
💡
Regular cleaning of filters and brushes increases the life of the Xiaomi vacuum cleaner by 2-3 times and retains 90% of the suction power throughout the entire period of operation.
