<p>The device has a cleaning head (10) which has a base part (11) and two brush elements (13a,13b) that are provided at opposite sides of the base part. The brush elements are displaceable in a cleaning movement relative to the base part. A fluid drive (15) is integrated in the base part, which is formed such that the flow energy transfers the fluid in the cleaning movement of the brush element, where the fluid is supplied under pressure.</p> |
