Design and Technology

Air Movement

The design of a bagless vacuum cleaner is focused on effectively moving air and capturing debris. At the heart of the device lies an electric motor that powers a fan to create suction. As the vacuum cleaner moves across surfaces such as floors and carpets, it sucks in dust, air, and debris, pulling them into the cleaner’s main body.

Centrifugal Force

Once inside, the debris and dust in the air are subjected to centrifugal force. This happens because the air, along with the particles, is rapidly spun around in a cyclonic motion within the vacuum cleaner’s chamber. Centrifugal force separates the heavier particles, like dirt and debris, from the air. These particles are then trapped in a collection bin or canister, while the cleaned air is expelled back into the room.

Filtration System

One of the key elements in a bagless vacuum cleaner is its filtration system, which often consists of multiple stages and filters. The primary filter is responsible for capturing larger debris, while additional filters, such as HEPA filters, are designed to remove much smaller particles and allergens. These filters work together to ensure that only clean air is released back into the environment.

In summary, a bagless vacuum cleaner relies on a combination of air movement, centrifugal force, and a multi-stage filtration system to effectively remove dust and debris from surfaces. The design of these machines, whether upright or canister, prioritises efficiency and ease of use for the end user. With their unique technology, bagless vacuum cleaners continue to be a popular choice amongst consumers.
