When I firsted turned it on the water pressure was squirting out the top pretty strong, then it starts to move, but seemed to skip a little, like it wasn't stong enough to even pull the cord in, So I pulled the robot over to me and then there wasn't any water squirting out the top at all, but I could feel it humming. Help, anyone know what is up? Thanks
ADMIN REPLY: Seems you have a broken wire...most likely in the terminal well of the motor. Dig out the putty and check the pump wires. Repair as needed. The break may be in the cable too. Check the page on troubleshooting.
