International ClassB09B 302AbstractAn automated power-driven pool cleaning apparatus is provided with a motion translating member that contacts the surface being cleaned, an associated signal transmitter and a sensor that is connected to the pool cleaner's programmed electronic control device, or chip, so that when the cleaner is moving, the mtm moves the signal transmitter past the sensor thereby providing an intermittent signal. When the cleaner stops moving, no intermittent signal is received and after a predetermined period of time, the control device causes the cleaner's drive means to move the cleaner in a different direction.Field of SearchSUBMERGED CLEANERS WITH AMBIENT FLOW GUIDESAutomatic controls With electric control Electrically controlled With movably or flexibly mounted spray or jet applying conduits or nozzles With spray or jet supplying and/or applying means For work having hollows or passages With movably or flexibly mounted spray or jet applying conduits or nozzles | |
