Friction support device for swimming pool cleaner |
摘要 |
A swimming pool cleaner is operable through a vibratory movement of its housing through a flow of water past a vibratory element carried within the housing . A friction support is carried by the housing and engages a surface to be cleaned. The friction support has a first end pivotally attached to the housing and a second free end in frictional contact with the surface to be cleaned. The friction support is further biased toward a first orientation and limited in its movement therefrom as the friction support is displaced during vibration of the housing and movement of the pool cleaner.
