Vacuum cleaners line Dreame V9 has proven to be reliable assistants in cleaning, but their performance depends on regular maintenance. Many owners face a drop in suction force or reduced battery life, unaware that the problem lies in the banal contamination of filter elements. Timely cleaning allows not only to return the device to factory capacity, but also significantly extend the life of an expensive engine.
In this article, we will discuss in detail the maintenance process of each component of a wireless vacuum cleaner. HEPA-filter, clear the cyclone block of fine dust and check the condition of the brush. Ignoring these procedures can lead to overheating of electronics, so it is important to devote time to the hygiene of your gadget.
Before you start disassembling, make sure the device is off and off the charger. The whole procedure takes no more than 15-20 minutes, but requires care, especially when working with porous filtration materials. Let's take a closer look at each step.
Preparation for cleaning and safety
The beginning of any maintenance process must be accompanied by compliance with the prescribed safety measures. Although the Xiaomi Dreame V9 is designed with the user in mind, there are electrical components inside the device that are sensitive to moisture. The first step is always to completely turn off the power and remove the battery if the design allows quick access, or simply ensure that the device does not turn on accidentally.
You'll need to prepare your workplace, and the best way to do this is to clean over a trash can or on a surface that's easy to clean, like the bathroom floor or the balcony floor, and you'll need to do this.
- 🧹 Soft brush to remove dust from hard-to-reach places
- 💧 Flowing water at room temperature
- 🧼 Neutral detergent (optional)
- 🧻 Dry lilaless napkins or towels
⚠️ Warning: It is strictly forbidden to use hot water (over 40).°C) for washing filters, as this may irreversibly damage the structure of the fibres.
You also need to release the dust container in advance. Press the unlock button on the case and pour out the contents. Don't try to push the garbage with your fingers into the duct, which can damage the sensors or the turbine impeller. If you notice large objects, carefully remove them with tweezers.
Cleaning of the dust and cyclone container
The main garbage tank in the Dreame V9 is made of durable plastic that is easy to clean, but it contains an important element of the filtration system, the cyclone, which creates a vortex flow that separates large dust from air, and over time, a layer of fine dust can stick on the walls of the cyclone and the protective net, which degrades the aerodynamics.
To clean the container effectively, remove the main unit. In some versions, the top of the filter can be detached from the dust bowl by pressing the appropriate latch. Rinse the plastic bowl with water. If there is a greasy coating on the walls (which is relevant for kitchen cleaning), use a drop of soft detergent.
Pay special attention to the cyclone's metal grid, which is often the bottleneck of the system, use a soft brush to sweep dust out of the mesh cells, and move from the inside out so as not to clog the debris deeper.
☑️ Cleaning the container
After washing, make sure all plastic cells are completely dry. Moisture entering the engine compartment during assembly can cause short circuits. Do not use a hair dryer to speed up the process, as high temperatures can warp the plastic.
Washing and maintenance HEPA-filter
The most important element in the air cleaning system is HEPA-In Dreame vacuum cleaners, it's responsible for delaying microscopic dust particles, allergens and bacteria, and it's this component that most often causes a decrease in traction when the user forgets to service it.
Remove the filter from the top compartment of the vacuum cleaner, which is usually cylindrical in shape and easily removed by light rotation or pulling, and visually assess its condition: if the gray surface has become dark gray or black, and the villi have stuck, the filtration is disrupted.
Wash the filter exclusively under a stream of cold running water. The direction of the water flow should be the opposite direction of the air flow when the vacuum cleaner is running (usually from the outside inwards, but it is better to pour water from top to bottom along the folds, not allowing a strong pressure to damage the structure).
⚠️ Attention: It is forbidden to wash HEPA-filter in the washing machine or use any chemical solvents and bleach.
After washing, thoroughly shake off the filter from excess water. Drying is the longest step. The filter must dry in a straightened form in a warm, well-ventilated place for at least 24 hours. Using a wet filter will cause water to enter the engine and the vacuum cleaner to fail.

Maintenance of motorized brush
The floor brush in the Dreame V9 kit often suffers from the hair, thread and fur of animals winding onto a rotating shaft.This creates additional resistance to the brush engine and can lead to a belt break or engine burnout. Regular brushing is mandatory for quality carpet cleaning.
Turn over the brush and look around the shaft. You'll see debris piling up around the edges and in the center. Use scissors or a special blade (often included) to gently cut the entangled hair. Try not to damage the bristles and the surface of the shaft.
After removing the windings, wipe the shaft with a wet cloth. Also check the side bearings of the shaft - they should rotate freely. If the shaft is jammed, you may need to take a deeper dismantling or replace the bearings, but in 90% of cases, just remove the winding.
- ✂️ Carefully cut the wound hair along the shaft
- 🧹 Clean out the debris from under the bristles
- 🔄 Check the free rotation of the shaft with your hand
- 🔌 Make sure the charging contacts on the brush are dry and clean.
Remember to clean the duct connecting the main pipe and the brush, and often there are dust lumps that block the flow of air, you can clean it with a long brush or just blow it at one end.
Diagnostics and cleaning of the engine compartment
The engine unit in the Xiaomi Dreame V9 contains the engine and electronics system. Unlike the container, this unit cannot be washed with water. However, the inlet where the container is inserted requires attention, and this is where fine dust can get in, bypassing the filters if they were installed loosely or damaged.
Carefully inspect the netting at the entrance to the engine compartment. If you see a gray plaque there, carefully remove it with a dry soft brush. You can use a long-nozzle vacuum cleaner to suck dust from the surface of the grille, but do not touch the interior with foreign objects.
| Element | Type of cleaning | Frequency | We can wet. |
|---|---|---|---|
| Dust container | Water washing | After every cleaning. | Yes. |
| HEPA-filter | Washing and drying | Every 1-2 months | Yeah (dry 24h) |
| Motorized brush | Mechanical cleaning | Once every 2 weeks | No (only the shaft) |
| Engine bay. | Dry brushing | Every 3-6 months | No. |
If you notice a strange smell of burning or sparkling, immediately stop using the device, this may indicate that moisture or a large object enters the engine turbine, in which case self-cleaning can be dangerous, and it is better to contact the service center.
💡
To remove the persistent odor from the vacuum cleaner, you can wipe the inner surfaces of the container with a weak solution of vinegar, but only after careful check of the instructions for material compatibility.
Assembly and seal check
Once all the components have been dried and cleaned, the assembly stage begins. HEPA-Make sure it's locked and locked, and a loose fit is the most common cause of engine failure, because the untreated air goes directly into the turbine.
Put the structure in reverse order: container on the engine unit, pipe, brush. Before turning on, check all the docking units. They should snap with a characteristic click. If any element dangles or does not fit into place, then the assembly is not done correctly.
Turn on the vacuum cleaner at minimum power. Put your hand on the outlet (back of the device). The air flow should be uniform and strong. If you hear a whistle, it means that the tightness of the connections is broken somewhere. If the hum is quieter than usual, maybe the filter is still wet or crooked.
⚠️ Warning: Do not leave the vacuum cleaner on charge immediately after cleaning if it is too hot.Let it cool at room temperature for 30 minutes. 💡Proper drying HEPA-24 hours of filtering is the key to a long life of your vacuum cleaner engine. Never ignore this stage. Frequently asked questions (FAQ) How often should I change HEPA-filter V9? With regular cleaning and drying, quality HEPA-The filter lasts 6 to 12 months. However, if you clean very often or there are animals in the house, the resource can run out faster. Change the filter when it physically collapses or stops being cleaned with water. Can you wash the container in the dishwasher? The manufacturer does not recommend dishwashers, high water temperature and aggressive detergents can deform plastic or damage sealing gums, which will violate the tightness of the system. Why did the vacuum cleaner become quieter after cleaning? Most likely, the filter did not have time to completely dry. Wet fibers stick together and do not let air through. Also check if you forgot to remove the safety net from the new filter when you installed it, if you were replacing it. What to do if water got into the engine compartment? Immediately turn it off. Do not try to "dry" the vacuum cleaner as completely as possible, remove the battery (if possible) and leave to dry in a warm dry place for at least 2-3 days. Turning on the wetty devices will lead to the original manufacturers of the electricians from the electric grids. When buying, pay attention to the packaging and availability of holograms, as the market is flooded with cheap copies with low filtration efficiency.
