Abstract
An improved power conduit for use with automatic pool cleaners particularly configured to avoid the formation of persistent coils and/or knots. Embodiments in accordance with the invention are characterized by the use of at least one axially stiff elongate member together with axially flexible and axially swivelable means for coupling said stiff member between a stationary power source fitting and a cleaner. The axially flexible and axially swivelable means can be implemented in a variety of ways, e.g., a flexible elongate hose member and a swivel coupling.
