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 for removably holding a dusting cloth or cover, whereby it can be used similarly to a conventional duster. The vacuum source can be fluidly connected to and draw a vacuum airflow through the duster assembly, for example, through and/or around the dusting cloth. In some implementations, this is done by drawing the vacuum airflow toward opposing lateral portions of the duster assembly. 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, as desired.
