Working of a vacuum cleaner
1. It removes debris soil and or water from a surface by suction
2. All vacuum cleaners operate on the principle of suction
3. An electric current operates the motor
4. The motor is attatched clean to a fan which has blades like an aeroplane propeller
5. As the blades turn they force air inwards the exhaust port or outlet
6. Thus a partial vacuum is created in the vacuum cleaner
7. This causes air pressure to decrease in the vacuum cleaner as compared to the outside
8. The partial vacuum at lower pressure causes a suction action
9. Air from the outside rushes in through the intake port or inlet
10. Rotating brushes positioned near the inlet kicks up dirt and dust from the surface being cleaned
