A simple, reliable and convenient hand-held vacuum cleaner
Since the person moved from the cave to a stationary dwelling, he constantly faces the problem of dust removal. In an effort to facilitate life, all this time, inquisitive minds sought to create adaptations to resolve this issue. The first such unit appeared in the XIX century. It was a cumbersome machine that did not collect dust, but only inflated it. Two people were needed to service the device, the first of which inflated the fur, and the second carried the sleeve. The idea is not to inflate, but to suck in the dust suggested by the English engineer Hubert Booth (Hubert Booth). So, in 1901, the first vacuum cleaner appeared, which had huge dimensions and worked on gasoline.
If we talk about the power consumption, here the manual vacuum cleaner certainly does not have worthy competitors, but its suction power is much inferior to its more cumbersome but powerful counterparts. So, for a quality cleaning of the premises, of course, it will not work.
A low-power vacuum cleaner will not be able to fully clean the interior of dust, and with a large capacity it will consume more energy. Car vacuum cleaners are usually equipped with a rechargeable battery pack or can be powered by a cigarette lighter.
Another important point is the bundling. When choosing a manual vacuum cleaner to clean the car, you need to make sure that it is equipped with a microfilter, and that there are additional replaceable filters. In addition, it is necessary to check the number of nozzles capable of removing dust from any, even the most inaccessible places. Well and one more basic factor is, certainly, the price. It can range from 800 to 4000 rubles, although there are more expensive models (depending on the manufacturer, design, capacity, etc.). Such a characteristic as the noise level can be neglected, since almost all manual vacuum cleaners work virtually silently.
