A common nuisance in cleaning is the gnarled and twisted strands of hair on drain strainers, especially for people with long hair. This design improves traditional designs by adding a push button on drain strainers. Hair strands follow water current down to an elastic comb-shaped structure. The comb-shaped structure allows easy cleaning—users can simply disassemble the structure and remove the hair with a swipe of hand or with some water.
