Unlike the use of wheels that most vacuums have, the Dyson DC15 upright vacuum has a large yellow ball that will allow the vacuum to pivot and roll with the greatest of ease. With the DC15, you simply turn your wrist and the entire vacuum cleaner will change direction. The ability to maneuver this easily is something that is commonly associated with canister style vacuum cleaners.
In addition to the unique yet innovative ball design, the Dyson DC15 also offers quite an interesting filtration system. No matter what you may think or hear, Dyson vacuums don’t use filters in the way that most vacuum cleaners do.
With the Dyson DC15, the air and dirt are sucked into the container where the outer cyclone removes large particles such as food, hair, and even fibers. The air will then move into the shroud and inner cyclone where it is rotated with a higher velocity to drop fine particles of dust out of the air.
From the inner cyclone, the air will move about through a washable inner foam pre filter where a majority of the particles will remain trapped. This feature helps the DC15 to keep dirt and debris trapped inside and out of the motor.
