Choosing a vacuum cleaner

Conventional vacuum cleaners are not able to provide perfect cleaning. Part of the dust seeping into the room, and an exhaust stream raises have not yet cleaned the dust, which causes the aggravation of pathological conditions in people with allergies. In addition, the bulky unit has a carry over throughout the house. The solution was built in cleaning systems. Use of such devices can be in a city apartment and a country house or even in the office. The thing is: the heart of an embedded system cleaning - block suction musoronakopitelem set off premises (on the balcony, utility room, closet, etc.). From him around the house quietly pulled a plastic pipe, mounted on the wall, which ends on a pneumatic jack (there may be several). In the socket is inserted a flexible hose having a plurality of nozzles - and the dust is gone. Exhaust air at the same time takes place either outside or in non-residential premises, or directly into the sewer. When such cleaning removes even the most finely dispersed dust. To date, the central vacuum uses several technologies of air purification - through filters of various types, with a "cyclone" or with the use of water. Sometimes a combination of these methods. All of them have their advantages and disadvantages. Vacuum cleaners with filters of various types (tissue, bags, cartridges). Are the most effective filter cartridges. Advantages - high degree of clean air, reliable motor protection. Disadvantages - significant resistance in the suction air filter is dirty, it needs periodic cleaning or replacement. Vacuum cleaners with water filter can suck water and dirt directly into the central facility, where waste is merged into drains. Advantages-no filter, universal cleaning, no need to remove waste. Disadvantages - increased noise and power consumption, the possibility of blockages in pipes and sink, as well as the formation of a favorable environment for bacteria and other microorganisms in the pipes and the installation itself. In the vacuum cleaner with a "cyclone" air purification is due to centrifugal forces generated inside the air vortex. Advantages - no filter, constant suction power. Disadvantages - low degree of purification of air, insufficient protection of the motor from dust. Today the Russian market offers a variety of built-in vacuum cleaner companies. This is mainly American or Canadian firms (VACUFLO, DYSON, HUSKY, SILENT MASTER, BEAM), but there are Europeans: THOMAS and KRONEMARK (Germany), AERTECNIKA (Slovenia), TECNONET (Italy), etc. The estimated cost depends on the built-in vacuum cleaner size and number of floors the premises where it is necessary to pull the communication. One outlet will provide cleaning 50 m2. In rooms up to 500 m2 are used for household cleaners modifications up to 2000 Watts. The price of the power unit is in the range 17-60 thousand rubles. Other costs - the cost of planning decisions, piping and fittings, nozzles, etc. - are calculated individually.
