Patent attributes
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.
