Finished filling up the new pool on Thursday, test fired the pump station and added chemicals on Friday. Sent the new 2010 version of the Pool Rover Jr. on it's first underwater maneuvers this morning to get rid of mostly red clay dirt that had blown into the pool as they back filled around it. Pretty fine stuff. This model does NOT have the programmable timer on the brain box. it cleaned the pool in an hour or so as advertised. I let it run for another hour to check and see if it would automatically turn itself off. Turned off after 2 hours as advertised. Did an excellent job on the flat bottomed pool. Thanks to all who recommended this model for an AGP.
