Abstract
A floor cleaning device employing a brush assembly is provided. The brush assembly includes a front brush and a rear brush that spin about an axis line generally parallel to the surface being cleaned. The spinning rotation of the brush along with the configuration of the housing help provide an airflow path that sucks debris from the surface being cleaned. The debris is directed to a hopper wherein larger items are captured and smaller items are suctioned into a vacuum bag.
