  • Publication number: 20100083463
    Abstract: A suction cleaner includes a suction unit for creating a flow of air and a flexible suction hose having a hose inlet at which air may be drawn into the suction hose. The suction hose leads from the suction unit and includes a first hose portion and a second hose portion having a connection to the first hose portion. The second hose portion includes the hose inlet. The suction unit includes a body that at least partially defines a storage volume in which the first hose portion can be accommodated when the first hose portion is in a contracted condition, and from which the first hose portion can be deployed when required. A first roller is positioned within the body and is supported on a first axis that is fixed with respect to the body. A second roller is positioned within the body and is supported on a second axis. The second axis is movable along an arc. A portion of the arc has a focus point positioned on the same side of the arc as the first axis.

  • Patent number: 7410516
    Abstract: An upright vacuum cleaner comprises a housing having a suction airstream inlet and a suction airstream outlet. A dirt container is selectively mounted to the housing for receiving and retaining dirt and dust separated from the suction airstream. The suction airstream inlet and the suction airstream outlet are in fluid communication with, respectively, an inlet and an outlet of the dirt container. The dirt container includes a first cyclonic airflow chamber and a second cyclonic airflow chamber, each cyclonic airflow chamber including a longitudinal axis. The second cyclonic airflow chamber is spaced from the first chamber, wherein the first and second chambers are each approximately vertically oriented and are arranged in a parallel relationship. An air manifold is disposed at a top portion of the dirt container. The air manifold includes an inlet section through which dirty air passes and an outlet section.
