摘要

The cleaner (1) has a suction mouth (5) and a rear suction mouth limit unit (7) that is arranged in a driving direction (r) and charged by an air blast flow (B) directed in a opposite direction to a suction air flow (S). The air blast flow strikes on a floor, and is separated from the suction air flow. The limit unit is directed in an outlet region (10) in the driving direction running to a floor. A brush roller (2) is arranged in the suction mouth, and the limit unit ends above the floor.
