Vacuum Cleaners. History And Present Time

Differing from our well-known models, the first specimen didnt suck the dust inside at all

, as it is presented now and just sprayed it everywhere into the air. Such a cleaning machine consisted of a special hose and bellows. It was very difficult for a singular person to operate it and thus one needed at least two persons to work a vacuum cleaner of such a type. It is possible to list quite a lot of defects for such a construction the dust was sprayed everywhere extensively and the big size of the model was not very comfortable for an ordinary person.

Some decades afterwards Hubert Booth improved this device and vacuum-cleaner got the design close to the modern one. Now the dust was not being sprayed everywhere but sucked into a special tank. The advantages were certain because the new device was being operated with petrol and didnt demand any physical efforts although his size still remained quite impressive. Thus for cleaning the surface of the carpet one should roll the vacuum cleaner to the window and the hose, intended for sucking must be pulled inside it. But the period when vacuum cleaner was equipped with an engine can be called a real progress. Now the size of this device is not big, it is easy to operate and very effective. It is not possible to imagine presently the device to be more convenient for carpets cleaning. Besides, one has already created new varieties of vacuum cleaners working according to new principles.

Domestic dry vacuum cleaners

This is the most popular type of vacuum cleaners which would be found practically in all the shops. Their main advantages are considered to be comfortable usage and quite a good price. They can be perfectly used for home and carpet cleaning, uncovered floor or furniture. The construction of the device is quite simple - there is a vacuum fan which is sucking the dirty. Afterwards the dirty is filtrated and the better filtration system is, the cleaner air will be in the room. Thats why this factor should be paid the most attention to, while buying the vacuum cleaner.

Wet and dry vacuum cleaner

Wet and dry vacuum cleaners have more functions. They can be used as for wet cleaning, window washing, rooms deodorizing but for collecting the spilled liquids as well. Their cost is considerably higher than that for dry cleaning and the size of the device is much bigger as compared with the vacuum cleaner of medium size. Thus in the most cases these vacuum-cleaners are used for the offices or highly dirtied rooms. The construction of the device is simple - there are two tanks inside the device. First contains some liquid and second is sucking the dirty. The liquid from the first tank is transferred through the hose to the surface to be cleaned and afterwards is moved away immediately. This is the principle of the cleaning.

Vacuum cleaners with water filter

The vacuum cleaners with water filters are justly considered to be the best, cause differing from dry vacuum cleaners the dust, which is sucked into the water filter is plunged into water deeply, keeping the particles of dirty inside. According to the statistics of air cleaning, this variety of vacuum cleaners has the highest indexes. Their price varies from 300 to 500 USD.

Steam cleaners

Steam cleaners are perfect devices for dry and wet cleaning. Owing to the special device which is making steam, this vacuum cleaner can be easily used for any types of dirty cleaning simultaneously the air and collecting all the dirty practically from any surface. It can clean dust, fat, sticky stains and everything which sometimes is beyond of the possibilities as for the other vacuum cleaners. Besides all abovementioned, this cleaning is making disinfection too, because the temperature can reach 150 degrees.
