Abstract
Abstract A cleaning brush device having a rectangular housing with a roller brush rotatably mounted on the bottom wall. The rotary brush protrudes through a bottom opening to perform a carpet sweeper type action. The device also has a combined brush and sponge implement removably mounted in a longitudinal recess of a sidewall. Either end of the implement is used to sweep the dust particles into a dustpan which is hingedly mounted over an elongated opening in the other sidewall. The dust particles from both the rotary brush and the dustpan operations are collected in a compartment of the housing.
