First claim
Opening claim text (preview).
We claim: 1. A cleaning brush for a pool cleaning apparatus, the cleaning brush comprises: a central portion that has a longitudinal axis; a right handed fin that surrounds multiple times a first section of the central portion; a left handed fin that surrounds multiple times a second section of the central portion; wherein each one of the central portion, the first section of the central portion and the second section of the central portion has a cylindrical shape; first protuberances that are oriented in relation to the right handed fin; and second protuberances that are oriented in relation to the left handed fin. 2. The cleaning brush according to claim 1 , wherein the first and second sections are of equal length. 3. The cleaning brush according to claim 1 , wherein the first and second protuberances are substantially parallel to the longitudinal axis. 4. The cleaning brush according to claim 1 , wherein the right handed fin and the left handed fin are mutually symmetrical about a symmetry axis that virtually separates the central portion to the first and second sections of the central portion. 5. The cleaning brush according to claim 4 wherein the symmetry axis is normal to the longitudinal axis. 6. The cleaning brush according to claim 1 wherein each one of the right handed fin and the left handed fin defines a helical path. 7. The cleaning brush according to claim 1 wherein the right handed fin surrounds the first section of the central portion eleven times. 8. The cleaning brush according to claim 1 wherein the first protuberances and the second protuberances are mutually symmetrical about a symmetry axis that virtually separates the central portion to the first and second sections of the central portion. 9. The cleaning brush according to claim 1 wherein the first protuberances and the second protuberances are identical to each other. 10. The cleaning brush according to claim 1 wherein the first protuberances and the second protuberances are arranged in rows that are parallel to the longitudinal axis and are extending radially from the central portion. 11. The cleaning brush according to claim 1 wherein the first protuberances are oriented in relation to the right handed fin by an orientation that has an absolute value of at least 25 degrees. 12. The cleaning brush according to claim 1 wherein the first protuberances are oriented in relation to the right handed fin by an orientation that has an absolute value of at least 55 degrees. 13. The cleaning brush according to claim 1 wherein the first protuberances are oriented in relation to the right handed fin by an orientation that ranges between 5 to 90 degrees.
