Apparatus for cleaning surfaces

摘要

An apparatus for cleaning surfaces has a cleaning head which includes a base part and at least two brush elements which are provided at opposite the sides of the base part and which can be set into a cleaning movement relative to the base part. A fluid drive is integrated into the base part and is designed to convert the flow energy of a fluid supplied to the base part under pressure into the cleaning movement of the brush elements. The fluid drive has a drive member, in particular a turbine wheel or a bucket wheel, which is driven by the fluid and by which both brush elements can be driven together.

1. An apparatus for cleaning surfaces, having a cleaning head (10, 10′) which includes a base part (11) and at least two brush elements (13a, 13b, 30) which are provided at opposite sides of the base part (11) and also supported by the base part and which can be set into a cleaning movement relative to the base part (11),
wherein a fluid drive (15) is integrated into the base part (11) which is designed to convert the flow energy of a fluid supplied under pressure to the base part (11) into the cleaning movement of the brush elements (13a, 13b, 30); and wherein the fluid drive (15) has a drive member (19) which is rotatably driven about an axis by the fluid and by which both brush elements (13a, 13b, 30) can be driven together, said brush elements positioned on opposite axial ends of said drive member, wherein the fluid drive (15) includes a transmission unit having an inlet acted on by the fluid at the drive member (19) and two outlets acting on the brush elements (13a, 13b, 30).
