Abstract (en)

[origin: EP1571261A1] The machine has a hydraulic engine (140) with an exhaust circuit connected respectively to upstream and downstream chambers of each of two hydraulic jacks (170). The circuit is connected in such a way that each jack applies a rotary brush (130) on a surface to be cleaned by exerting force of constant intensity on it, in a particular range of pressure measured in an intake circuit of the hydraulic engine.
