Abstract

A cleaning device includes: a main body having a front edge; a suction device having a suction opening and a suction channel; a brush assembly having a rotatable roller brush; and an apparatus for wetting a floor to be cleaned with liquid, the apparatus being associated with the roller brush. The suction opening and the roller brush are arranged in the main body in such a manner as to face the floor to be cleaned. The suction opening has a first wall facing the front edge of the main body and a second wall facing the roller brush. The roller brush loosens dirt from the floor to be cleaned. A pivotable lip is associated with the suction opening and alternately rests against the first wall or the second wall.
