Classification and working principle of Vacuum Cleaners The Vacuum Cleaner relies on the motor to generate a pressure difference in the vacuum state formed inside to absorb dust, and then the dust filter device intercepts the dirt and discharges the air to complete the dust removal process. The "suction force" that affects the vacuuming effect depends on the resultant force of the wind and vacuum force generated, but these two factors have opposite characteristics. When the wind force is large, the vacuum force becomes weak, and when the vacuum force is strong, the wind force becomes small. The maximum value of the combined force of the two is the "suction power" which represents the ability of the Vacuum Cleaner. This is an international standard defined by the International Organization for Standardization (ISO) to express the performance of Vacuum Cleaners. The Vacuum Cleaner is mainly composed of a shell, suction head, dust chamber, motor, and other parts.
