Convenience without maximum cleaning ability isn't a true step ahead. To provide a better bagless, the Hoover WindTunnel™ Bagless upright provides the double impact of WindTunnel technology with Hoover's latest innovation, the Twin Chamber™ System.
The Twin Chamber System, designed with two stages of filtration, provides longer cleaning performance by helping prevent build-up and clogging of the cleaner's HEPA filter. Heavy dirt entering the vacuum is drawn into an empty chamber and kept there by a permanent pre-filter between the two chambers.
The pre-filter allows only fine particles to pass into the second chamber, where they are stopped by a HEPA filter. The HEPA filter has a coated surface that helps shed dirt, helping to prevent build-up that can clog and restrict airflow. Outside the Twin Chamber System is a final filter.
The Hoover WindTunnel Bagless is designed with an easy-to-remove dirt chamber with lid for convenient dirt disposal.
