| 摘要 |
The invention relates to an apparatus for cleaning a surface which is immersed in a liquid, comprising a hollow body, guiding members defining at least one axle, a filtration chamber, at least one electric motor, a pumping device which creates, in a normal cleaning direction through a filtering device, a liquid flux which is discharged via at least one main outlet, and at least one secondary liquid outlet arranged so as to orientate a current of liquid which is discharged in a backward direction via this secondary outlet so that this current creates a secondary hydraulic reaction force which generates a nosing-up torque of the apparatus by the hollow body being pivoted about the axle. |
