portable vacuum cleaner
Then how and where does it catch the dirt and dust? There are filters made of special cloth or special filter papers (these papers can withstand the impact of high speed air and dirt). You just have to place the filters just before the fan in its protective housing and that’s it.
When you switch on the vacuum cleaner, it creates what engineers call as draft, which is plainly the suction power. The wire brush fixed at the end of your flexible hose, through which the dust enters the machine, scrubs & unsettles the clinging dusts from, say, your carpet and they are immediately picked up by the high speed air when to rush into the hose from allover.
