Brrrrahhhh! It may sound like a roaring monster, but it’s only a vacuum cleaner doing its dirty work. The noise comes from an electric motor that runs a fan. The fan helps the vacuum cleaner suck the dirt up the hose and into the bag.
When you turn on the vacuum cleaner, the fan starts. It draws air from the bottom of the vacuum cleaner up into the dust bin or bag. As the air moves up, it leaves an empty space at the bottom of the vacuum cleaner. Any empty space is called a vacuum. That’s how the vacuum cleaner got its name.
A brush at the bottom of the cleaner helps loosen dirt in the rug. This brush is called a beater brush. A rubber belt connects the brush to the motor. As the motor spins, the brush spins and makes the rug vibrate. The vibration loosens the dirt. The vacuum pulls more air and dirt into the dust bin or bag.
When the dust bin gets full, it needs to be emptied. Or, when the bag gets full, it needs to be thrown away and replaced with a fresh bag.
