VACUFLO True Cyclonic Power Units provide sustained cleaning power by separating the dirt from the airflow. Unlike vacuum systems that rely on bags or filters, the powerful performance of the VACUFLO system does not decrease as dirt accumulates. VACUFLOs Cyclonic Filtration Technology creates a powerful centrifugal force that separates dirt and debris from the airflow. As the dirt spins around, the air pressure forces it through the cyclonic cone and deposits 96-98% of the vacuumed dirt into an easy-to-empty canister. The remaining 2-4% of fine dust particles are exhausted outside. With VACUFLO True Cyclonic, there is no chance for dust or vacuum odors to re-circulate into your living area. The result is a cleaner, fresher and healthier home.
