The basic principle of a vacuum cleaner involves the following components:

Pre-cut plastic components for the body
DC motor
Fan Blade Battery Holder with On/Off Switch
Straw

Motor: The heart of the vacuum cleaner is an electric motor. This motor rotates at high speed, generating the necessary power for the machine's operation.

Fan: Connected to the motor, a fan is responsible for creating suction within the vacuum cleaner. As it spins rapidly, it pulls in air and any debris along with it.

Airflow: The fan draws air into the vacuum cleaner through an intake, often located on the nozzle or brush head. This air carries dust, dirt, and particles from the surface being cleaned.

Suction: The drop in air pressure inside the vacuum cleaner causes ambient air to rush into the machine through any openings it can find. This rush of air, often at high velocity, effectively sucks in dust and dirt from the surface being cleaned.

Cleaning Attachment: To facilitate cleaning, vacuum cleaners are equipped with various nozzles and attachments, such as brushes and crevice tools, designed for different cleaning tasks.

Collection Container: The collected dust and debris are stored in a collection container or bag. Users can easily remove and dispose of the container's contents when full.

In summary, a vacuum cleaner works by utilizing a motor-driven fan to create a negative pressure zone inside the machine. This negative pressure causes ambient air to be drawn into the vacuum cleaner, carrying dust and dirt with it. The collected debris is filtered and stored in a container, while the exhaust air is expelled back into the environment, resulting in a cleaner living space. Vacuum cleaners are indeed practical tools that make cleaning more efficient and convenient.
