Additionally, the Delphi sports a Quiet Operation system which allows the phone or a radio to be heard while in use.
The Delphi's Vortex Motor System features a powerful but compact 1200 Watt motor while optimizing usage of power by utilizing its own created airflow for superior dust intake. Its CleanAir system utilizes electrostatically charged HyClean filtering dust bags and high quality air filter cartridges to ensure no dust leaves the Delphi once it is sucked in. Meanwhile, the Delphi's Quiet Operation system uses a motor suspension system and seal to ensure quiet performance.
