Abstract
A floor cleaning apparatus having a brush chamber formed in a main housing is provided. The brush chamber has a dirt inlet slot that faces the floor that is to be cleaned and extends over the width of the brush chamber transverse to the direction of work. Rotatably mounted in the brush chamber is a brush roller that is driven by a motor. The bristles of the brush roller extend outwardly through the dirt inlet slot. The brush chamber communicates via a connecting channel with a dirt collecting chamber. To ensure a reliable sweeping-up of dirt and a simple emptying of the apparatus, the dirt collecting chamber directly adjoins the main housing and is formed in an independent chamber housing that is separable from the main housing. The chamber housing has a sweeping ramp that leads to the dirt collecting chamber and a front edge that is remote from the dirt collecting chamber, extends transverse to the direction of work, and is disposed at approximately the path of the bristles of the brush roller.
