Experience powerful suction with the Helix System for longer lasting pick-up performance. Large dirt cup holds more dirt for more room-to-room cleaning. Dual Edge Cleaning provides Surround Suction® to clean hard-to-reach areas like baseboards and around furniture. The unique Helix cleaning system captures dirt and other debris using internal “ribs” that are incorporated into the Easy Empty™ Dirt Cup. This forces large particles, dust and other debris down to the bottom of the tank instead of up into the filter, helping the vacuum to work more effectively longer.
