A cleaning robot that may include a control unit, a drive motor, a jet generator, a housing, a waterline proximity sensor, a filtering unit and a brushing unit. The jet generator has first and second openings that are positioned at opposite sides of the housing. The control unit is arranged to control the jet generator for jetting fluids to thereby inducing the pool cleaning robot to move according to a waterline movement scheme when the pool cleaning robot is proximate to the waterline. The waterline proximity sensor is arranged to sense proximity of the pool cleaning robot to a waterline. The drive motor and the jet generator are substantially closer to a front edge of the housing than to a rear edge of the housing.
