| 摘要 |
The invention relates to a device for cleaning a surface submerged in a liquid, comprising: a hollow body; guiding members (5, 6) defining at least one axle; a filtration chamber; at least one electric motor; a pumping device that creates a flow of liquid in the normal cleaning direction via a filtering device; at least one main outlet (37) through which the liquid is released; and at least one secondary liquid outlet (50) arranged to direct a stream of liquid released in the reverse direction through said secondary outlet (50), such that, by reaction, the stream creates a secondary hydraulic reaction force generating a rear-end torque in relation to the device, pivoting the hollow body about the axle. |
