| 摘要 |
The invention relates to a cleaning rotor (1) having a longitudinal axis (L) , a base part (5), which extends concentric to the longitudinal axis (L), a he ad part (3) and a strut element (9) that extends between the base part and the head part. Said strut element (9) extends in a helical manner about the longitudinal axis (L). The invention is characterized in that at least one supporting part (7) is placed between the base part (3) and the head part (3 ) while extending parallel to the longitudinal axis (L). The strut element (9) is supported on the supporting part (7) and is concave over its length.</SDO AB>
