The #37704 TP-210 Turbo Cat utilizes a horizontal turbine design to keep the profile of the tool at a minimum for cleaning under and around furnishings. The T-shape permits cleaning up close to the legs of tables and chars. It also has a soft wrap around bumper and an agitator insures consistent performance on even the highest pile carpets. The turbine is black in color. The Turbo Cat requires NO separate power cords, batteries, or additional electricity. It also contains a unique brush roller, resulting in enhanced airflow and enhanced dirt pick up.  The chevron pattern design includes dual height bristles to ensure constant contact with the floor surface.  It's quiet as a mouse, with its bearing insulators which hold it firmly in place, reducing vibration.  The easy glide wheels provide top of the line maneuverability and responsiveness.
