Abstract: An automatic pool cleaner includes a housing having a bottom, an outer surface and an interior, at least two wheels connected to the housing and supporting the housing for rolling movement on a support surface with the bottom facing the support surface, a propulsion system in the interior configured to move the pool cleaner along the support surface, a suction inlet, and a scrubbing panel connected to the housing. The scrubbing panel includes at least one flexible panel and a resilient stiffener connected to the flexible panel that is configured to bias a planar portion of the flexible panel against the support surface when the wheels support the housing on the support surface.

Abstract: A circuit continuity test device is disclosed. The device utilizes a series circuit to provide a completed circuit for an external explosive or pyrotechnic circuit. The series circuit has a switch in the form of a light emitting diode and a power source. Upon coupling to a continuous external circuit, the diode is placed in an on state thereby illuminating and indicating a continuous external circuit.The device housing is a simple, compact and solid part. This allows the device to be used in a variety of environmental conditions and easily and inexpensively manufactured.
