We managed to separate the electricity from the water. I made these two elements no longer meet. I changed the position of the motor and regardless of the state of wear of the bearings and the oil seal, water no longer enters the electric motor. The penetration of water into the electric motor is the only cause of the total decommissioning of the classic cleaning robots, and the water in the electric motor could generate a short circuit and even fatal accidents.
