  • Publication number: 20100071151
    Abstract: Disclosed herein is a vacuum cleaner having a housing defining first and second ports. The vacuum cleaner also includes a cap assembly. The cap assembly includes a cap head to close the first port such that airflow is directed via a flow path to the second port, a sound-influencing material, the sound-influencing material removably held to the cap head and disposed within the flow path to reduce noise effected by the airflow. The flow path is configured to cause the airflow to pass through the sound-influencing material and the flow path to the second port. The sound-influencing material is removable to allow cleaning of the sound-influencing material. The sound-influencing material may include a reticulated foam roll disposed in the frame to diffuse the discharge airflow.

  • Patent number: 7669279
    Abstract: A wall-mountable mounting bracket and fluid-dispensing attachment for a vacuum cleaner. The attachment can be used to dispense cleaning fluid to an area to be cleaned. The fluid is sucked up along with dirt by the vacuum. A remotely-activatable valve allows user's to selectively shut off the flow of fluid. Retractable wheels can be moved between a usage position and a storage position. In the storage position, the axis of the wheels is above the lowermost side of the attachment and any overhang of the lowermost edge of the wheels is less than the thickness of a corresponding part of the mounting bracket.

  • Patent number: 7654480
    Abstract: The disclosed mulcher has a base unit and a shredding blade in a removable assembly. Two different embodiments are disclosed. In both embodiments, shredded material is removed from air exiting the shredding blade before it reaches an exhaust port. In one embodiment, the material is removed by a filter. In the other embodiment, walls are arranged so that debris must double back against high-speed airflow leaving the shredding blade before exiting the unit. The shredding blade can be mounted in front of and on the same shaft as an air impeller, with the back surface of the shredding blade being supported by the impeller. In another embodiment, the air impeller and the shredding blade are carried in assemblies that are separable from each other and are each separately attachable to a base unit. A detachable power module and a detachable blower are also shown. The power module has a safety switch that disables the power module when it is removed.
