A vacuum cleaner creates suction by using an electric motor to power a fan or impeller that rotates rapidly inside the machine. This creates a low-pressure area inside the vacuum, causing air to rush in through the nozzle and pick up dirt and debris.
The bag or canister in a vacuum cleaner serves as a container for the dirt and debris collected by the suction. As the air enters the bag or canister, the heavier particles fall to the bottom while the lighter particles are trapped by filters. This allows for easy disposal of the collected debris.
Different types of vacuum cleaners, such as upright, canister, and handheld, work in similar ways. They all use a motor to create suction and a bag or canister to collect debris. However, the design and placement of the motor and components may vary depending on the type of vacuum.
Filters in a vacuum cleaner are responsible for trapping particles and preventing them from being released back into the air. Some vacuums have multiple filters, such as a pre-motor and post-motor filter, to ensure that the exhaust air is clean.
Vacuum attachments, such as brushes and crevice tools, work by using the suction created by the vacuum to pull in dirt and debris from specific areas. The design of the attachment, such as a rotating brush or narrow nozzle, allows for more targeted cleaning of different surfaces and spaces.
