Beschreibung
Zusammenfassung:	A device for cleaning a surface (11) comprises at least one rotatable brush (3,4) which is provided with flexible brush elements (18) for contacting the surface (11) and picking up dirt particles (10) and liquid which are present on the surface (11) during a dirt pick-up period of each revolution of the brush (3, 4), and means for driving the brush (3, 4). A linear mass density of the flexible brush elements (18) is chosen such as to be lower than 50 g per 10 km, at least at tip portions, and an acceleration at tips of the brush elements (18) is set such as to be at least 3,000 m/sec2, at least at some time during another period of each revolution of the brush (3, 4) than the dirt pick-up period, namely a period in which the brush elements (18) are free from contact to the surface (11).
