On change of garbage collection units with a bag came vacuum cleaners with a cyclone filter. They work by the type of centrifugal force, which creates a spiral vortex and thus delays the dust particles in a special container. What it is - a cyclone filter for a vacuum cleaner has yet to be understood in more detail.
What is a cyclone filter in a vacuum cleaner?
In any vacuum cleaner there is a three-level filtration system and it is this one that is represented in this unit by a volumetric cyclone filter. In operation, a powerful air stream, together with the debris, enters a container designed to create a strong air vortex - a double cyclone. The outer cyclone produces a rough preliminary air purification, and the inner cyclone is already designed to retain smaller impurities that settle on the walls of the filter chamber under the action of centrifugal force. Pollution with a diameter of less than 5 microns absorbs a filter sponge, which is installed at the outlet of the container.
Now it is clear how the cyclone filter works in a vacuum cleaner, which has both advantages and disadvantages. First of all, this vacuum cleaner attracts the buyer with its low price and convenience. For a plastic container, unlike a bag, it is convenient to take care of, the period of its operation is not limited. The design of this technique is simple as two and two and to understand how the device works, maybe even a child. Such a vacuum cleaner can produce dry cleaning of any surface, and small overall dimensions and weight do not impose special restrictions in terms of storage.
Nuances of operation
Yes, a universal cyclone filter for a vacuum cleaner can not be named, because it is intended only for dry cleaning, but this is not its only drawback. Many users note a sharp drop in suction power as the dust bag is filled. In a good way the container needs to be cleaned after each cleaning, and the compact unit requires doing it several times in one cleaning, which is very inconvenient. This is especially true for vacuum cleaners who are forced to fight the long hair of the female half of the house and wool of domestic animals. They are wound on the conical part of the reservoir, causing the unit to buzz in a hysterical state.
But even regularly washing all the components of the container and filters, you can see that every day the suction capacity of the vacuum cleaner falls. The thing is that there is a clogging of HEPA-filters used in devices of this type, which are disposable and are not washable, and new ones are very expensive. In addition, many users are not satisfied that the vacuum cleaner can automatically shut down due to engine overheating and until it cools down, it can not be started. In addition, it spreads around itself an unpleasant smell, which is precisely the result of the accumulation and multiplication of all kinds of microorganisms, ticks and microscopic dust particles that are not subject to a clogged filter.
These are the pros and cons of a cyclone filter in a vacuum cleaner. Actually, the possibilities of this vacuum cleaner are the same as in the models of past years with bags, but only the replacement of fabric dust collectors by plastic already gives the unit an undoubted advantage, and the design is much more interesting. When buying, you need to pay attention to the power of the device - the higher it will be, the better it will suck. The presence of various attachments will facilitate the work of the owner to clean carpets, upholstered furniture, etc. Of the abundance of models from different manufacturers, you can always choose the unit that meets the requirements for it.
