Abstract

The self-propelled floor cleaner has a suction hose (13) and parallel air backflow hose (14) opening into a suction opening (20), with side walls diverging in the sweeping direction at an angle of 30-50 degrees and especially 34-48 degrees and forming a curved trailing wall (32). A base wall (33) extends forwards from the curved rear wall, at a drop angle of 5-15 degrees and especially 7-13 degrees , with a curved leading edge. The suction and backflow hoses are separated by a structured intermediate wall.
