The notable feature of Dyson's vacuum cleaners is their cyclonic technology. This innovation allows the vacuum to create a strong centrifugal force that separates dirt and debris from the airflow, preventing the need for traditional disposable bags. This means that the vacuum maintains strong suction performance over time, as the design efficiently captures particles without clogging. Cyclonic technology not only enhances the efficiency of the vacuum but also simplifies maintenance for the user, who can easily empty the dustbin instead of dealing with bags. This pioneering approach has become a hallmark of Dyson's brand identity and a key reason for its popularity in the market.
