Abstract

This invention discloses a roller brush used in swimming pool cleaner, including the roller body and the roller brush wrapped around the roller body. The inner side of roller brush in contact with the roller body outer surface. The roller body has a number of detent posts or grooves. The roller brush inner surface has a number of corresponding grooves or posts. Certain number of detent posts engages with grooves enable the roller brush and roller body positive interlock. For this reason, this roller brush invention allows positive and synchronize drive between roller body and roller brush, avoiding slipping drive. Moreover, this invention has simple construction, easy manufacture and assembly. This invention does not need to apply too much tension on the roller brush, reducing the flexible roller brush aging rate. It is therefore product life extended and maintenance cost lowered.

Claims
