Abstract: The invention relates to a device for cleaning a submerged surface comprising water jet propulsion means (19) that generate a propelling water jet, and means (19-23) for orienting the propelling water jet that allow orienting said water jet in two opposing so-called longitudinal propulsion directions, capable of imparting to the cleaning device two opposing directions of movement along an axis of movement (y). In the invention, the means (19-23) for orienting the propelling water jet are suitable for orienting the water jet in at least one third, so-called lateral propulsion direction, in which the water jet is oriented in a bisecting direction relative to the axis of movement (y) suitable for exerting a force capable of causing the cleaning device to pivot by oversteering.

Abstract: The invention relates to a pool-cleaning robot comprising a transport system that comprises at least one idle transport wheel train, a detritus suction system, and a system for detecting halting of said cleaning robot, the detection system comprising at least one transceiver of a light ray along an emission axis and at least one target that is secured to the transport wheel train, is aligned with said emission axis, and is suitable for reflecting said light ray so as to detect rotation of said transport wheel train.
