  • Patent number: 7784137
    Abstract: Handheld dust removal devices that selectively utilize vacuum pressure are disclosed. Preferably, each device includes a small lightweight handle that houses a vacuum assembly having an electric motor and a battery. The device further includes a duster assembly with elongate fiber strands that have elongate voids extending therethrough or thereinto. The vacuum source can be fluidly connected to and draw a vacuum airflow through the duster assembly, for example, through and/or around the fiber strands. In such configuration, the elongate voids of the fiber strands can at least partially direct or influence the travel path of dust, debris, and/or other particulates that are entrained in a vacuum airflow. Some implementations further include an auxiliary vacuum inlet that is adapted and configured for drawing large particles such as crumbs, hair, and others thereinto. The auxiliary vacuum port can be displaced from the duster assembly, e.g., mounted to the handle or elsewhere.

  • Patent number: 6799350
    Abstract: A suction-assisted dust mop enables dust to be efficiently attracted to the mop pile surface and held in place during cleaning. An electric motor powered blower or fan connected to a hollow tube generates a suction for cleaning dust at multiple suction holes in the tube walls which in turn generates suction in the fiber pile of the dust mop covering the suction holes. Chemical agents and/or an electrostatically charged fiber pile function along with suction to improve the efficiency of the dust cleaning process.

  • Patent number: 4800616
    Abstract: The cleaning apparatus is formed by a housing member adapted to be inserted into an air duct and which has two spaced apart ports for providing an air flow path through the housing member. A flexible hose has one end coupled to one of the ports and is employed for moving the housing member in the air duct and for providing a passage for the flow of air from or to the housing member. A turbine formed by blades fixedly connected to a shaft is supported within the housing member for rotation about the shaft upon passage of air through the housing member by way of the two ports. An off centered weight is coupled to the shaft for rotation with the turbine for causing the turbine and hence the housing member to vibrate upon rotation of the turbine whereby the housing member may vibrate against the inside wall of the air duct to loosen dust and other matter from in the duct and to facilitate movement of the housing member in the duct.
