(57) A pool cleaning robot (10) having an axis of symmetry (96) and a weight imbalance
across the axis of symmetry. The robot is adapted to propel itself along a trajectory
in the direction of the axis of symmetry (96) by generating a first suction, and alter
its trajectory as a result of the imbalance by generating a second suction which is
of a lower power than the first suction.
