Dyson vacuums offer you the newest in bagless, HEPA-filtered technology. Easy-to-maneuver durable frames are built to withstand a beating, and Dyson is the first vacuum cleaner designed to maintain powerful constant suction. (Dyson proves no loss of suction using the IEC 60312 Cl 2.9 test standard.) By making the air stream spin, dirt and debris are subjected to centrifugal force and thrown out of the air. Because the airflow is unobstructed by a bag there's nothing to clog and suction is not affected. Experience the sleek power as well as the joy of clean air and as they say at Dyson, "This should be the last vacuum you ever have to buy".
