One of the main features of a rubber broom handheld brush is its ability to effectively agitate carpet fibers. The rubber bristles are designed to create a static electric charge, which helps in loosening and lifting dirt, hair, and other debris from carpets.

Moreover, these brushes often come with different rubber bristle lengths to suit various cleaning needs. 

Another useful feature of a rubber broom handheld brush is the squeegee on the side. This can be used to clean up spills and messes on hard surfaces such as tile, hardwood, or laminate flooring. It also comes in handy when removing stains from carpet.
