Xiaomi Deerma vacuum cleaners are well-deservedly popular for their excellent value for money, but even the most reliable equipment requires regular maintenance. Over time, users notice that the suction force drops and the engine starts to work louder or warmer than usual. Most often, these problems are not caused by engine failure, but by the banal contamination of the filtration system, which simply needs to be cleaned.
Many owners face difficulties in initial disassembly for fear of damaging fragile plastic latches or impairing the tightness of the structure. In this article, we will discuss in detail the process of extracting, cleaning and correctly installing filter elements for various models of vertical and wired vacuum cleaners of this line.
Regular maintenance will not only restore the device to its former power, but also significantly extend the life of an expensive electric motor. Understanding the design of your Deerma will allow you to carry out prevention quickly and without risk to the gadget.
Design of the Deerma filtration system
The air purification system in vacuum cleaners Xiaomi Deerma is usually built on a multi-stage principle, which ensures the retention of the smallest particles of dust. HEPA-A filter that is responsible for finishing the vent air, preventing allergens from being released back into the room, and depending on the model, it can be made as a cylinder or a flat block.
The second important component is a foam or mesh pre-cleaning filter, which protects the main HEPA-This is a part of the waste that is being used to make a large piece of debris and wool, and it's a part that is often overlooked, even though it's a very critical part of the pollution that affects air throughput. DX700, These elements are combined into a single cassette, and in others, for example, DX1100C, may be separated.
The dust container in Deerma devices is designed to minimize user contact with dirt, but with prolonged use, fine dust still penetrates the nets. It is critical to understand that only the filter material can be washed, but in no case can you wet the plastic frame with electronics or sensors if they are present in the design.
Different series of vacuum cleaners have their own design mounting features: somewhere you use a bayonet connection, somewhere you use simple plastic clips. Before you start any manipulation, you need to make sure that the device is disconnected from the power grid to prevent accidental activation.
Preparation for maintenance and security measures
Before you start disassembling, you should prepare the workplace. You will need a well-lit surface, dry wipes made of microfiber and possibly a soft brush to remove dust. Do not start cleaning if the vacuum cleaner has just worked and the engine is hot - let it cool for 15-20 minutes.
Be sure to disconnect the power cord from the socket. If you have a wireless Deerma model, remove the battery if the design allows it, or make sure the device is turned off by the power button. This is a basic electrical safety rule that you can't ignore.
Check for spare filters. Often after washing, it takes time to dry completely (up to 24 hours), and the use of a wet element is strictly prohibited, so having a replacement kit will allow you to not interrupt the cleaning.
☑️ Checklist before the start of work
Carefully inspect the case for visible damage, if the plastic is cracked or deformed, disassembly can aggravate the situation, in such cases it is better to act with extreme caution or contact a service center.
How to remove the filter in the Deerma DX700/DX710 model
The DX700 and DX710 are classic wired vertical vacuum cleaners with a cyclone system. The filter element is accessible as conveniently as possible for the user. First, you need to disconnect the dust collector from the main engine unit.
After the tank is separated, flip it over and find a round cover at the bottom or side (depending on the modification) that is usually marked with a filter icon or HEPA text. To open it, you need to turn the lid counterclockwise until the characteristic click or loosening of the latches.
Remove the cylindrical filter. Inside, you'll see the corrugated material itself and perhaps an extra sponge. Carefully pull the central plastic part to reach the entire block. Don't put too much effort if the element is stuck -- it's probably heavily clogged with dust and requires careful loosening motions.
What to do if the lid does not open?
After extraction, examine the condition of the corrugated corrugated urine, if it is gray or black, filter immediately, and check the cyclone net inside the container itself, which can also be washed under a stream of water.
Discussion of cleaning system in Deerma DX1100C and analogues
The DX1100C and its modifications (VC20, VC21) have a slightly different design, where the filter element is located at the top, closer to the air outlet, where the removal process requires consistent action to avoid damaging the plastic guides.
First, remove the dust container by snapping it off the main body. Then, look at the top of the device: there's a protective grille that holds onto the latches. Carefully tuck it in or press the latches to gain access to the insides.
The filter in these models is often flat or slightly curved. It can be secured with an additional plastic holder. Remove the holder by pulling it up or sideways, and remove the filter element itself. Be careful: some versions of Deerma use a dual filter, the main and the secondary, placed on top of each other.
Don't confuse the side of the installation when you build it. The plastic frame usually has a TOP or arrow marking indicating the direction of the airflow. Putting the filter upside down will break the leakage and the dust will bypass the cleaning, getting into the engine.
Rules of cleaning and drying of filter elements
Once you've managed to remove the filter from the Xiaomi Deerma vacuum cleaner, the cleaning phase begins: rinse the element only under running water at room temperature. Use a soft brush to remove the ingrained dust from the folds of corrugated corrugated, but don't brush the material too aggressively so as not to damage the microfibers.
It is strictly forbidden to use detergents, powders or air conditioners for laundry. HEPA-It's enough clean water and mechanical shaking.
The most important step is drying. The wet filter is a breeding ground for bacteria and causes motor failure. Leave the cell to dry in a well-ventilated place in a horizontal position. Do not use a hair dryer, battery or direct sunlight to speed up the process, because high temperatures deform plastic and the glue that holds the folds together.
| Type of pollution | Cleaning method | Time to dry | Replacement frequency |
|---|---|---|---|
| Fine dust | Water washing | 12-24 hour | 6-8 months |
| Animal fur | Mechanical removal + water | 12-24 hour | 4-6 months |
| Construction dust | Replacement (not recommended to wash) | - | Right away. |
| Mold/Smell | Replacement is mandatory | - | Immediately. |
The filter is fully operational only after drying out, even if it looks dry, there may be moisture inside the corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrugated corrug
Typical errors and warnings
⚠️ Warning: Never turn on the Xiaomi Deerma vacuum cleaner with a wet or not completely dried filter. Getting water into the electric motor will lead to corrosion of the winding and irreversible failure of the device, which is not subject to warranty repair.
A common mistake is to try to knock the filter against the wall or floor for cleaning, which leads to deformation of the plastic frame and impaired the density of the sealing gum, as a result, the dust will pass the filter, settling on the inner walls of the vacuum cleaner and the engine.
And users often ignore the condition of the sealing rings, and the rubber band has to be clean and elastic, and if it's lost its elasticity or broken, it has to be replaced, otherwise the entire filtration system will become ineffective.
💡
Use a soft toothbrush to clean the folds carefully HEPA-This allows you to remove dust from the depths of the corrugated water, where the flow of water does not penetrate.
Don't try to repair a torn filter with tape or glue. A damaged structure won't be able to trap small particles, and they'll quickly disable engine bearings. It's cheaper to buy a new consumable than to change the engine.
When a filter replacement is needed
Even with regular cleaning, the life of any filter material is not infinite. HEPA-filters in Deerma vacuum cleaners every time 6-8 However, there are signs that urgent replacement is needed.
If after careful washing and drying, the suction force has not recovered, and the engine continues to hum with overload, then the pores of the material are finally clogged with microscopic dust that cannot be washed out, and the appearance of an unpleasant smell of burning or dust from the exhaust hole is also a sign of wear.
Visual inspection is also informative: if the filter corrugated darkened to black, became brittle or microcracked, the element should be disposed of. Using a worn-out filter negates all the benefits of the cyclone system.
💡
Timely replacement of the filter is not just hygiene, it is the protection of the engine of your vacuum cleaner from overheating and abrasive wear.
The original filters for Xiaomi Deerma can be found by the model marking. When buying analogues, pay attention to the density of the material and the quality of the sealing gum.
