Abrégé

The invention relates to a movable surface-cleaning device (1) comprising: a carriage (3) with a nozzle-holder rack, a guide system comprising at least one guide profile (6) on which the carriage (3) with a nozzle-holder rack moves, a flexible pipe (2) for a cleaning fluid supplying the nozzle-holder rack, motorisation means (7) for actuating the carriage with a nozzle-holder rack along the guide profile (6), and pressure-generating means for supplying the flexible pipe (2) with the pressurised fluid. According to the present disclosure, the motorisation means (7) comprise a hydraulic motor which is supplied with pressurised fluid by the pressure-generating means from a first branch, and which is configured to move the carriage with automatic reversal of the direction of rotation of the motor upon hydraulic detection of end-of-travel stops.

Abrégé

The invention relates to a motorisation system (1) for a trolley (100) comprising a nozzle rack (101) and a flexible pipe (200) configured to feed the nozzle rack (101), said motorisation system (1) comprising: - a frame (2), - a rotatable motorised roller (3), - a counter-bearing roller (4), - means for driving the motorised roller (3), in which the motorised roller (3) and the counter-bearing roller (4) are configured to drive the movement of said pipe (200) by friction with said pipe (200), said motorisation system (1) further comprising transmission means synchronising the rotation of the motorised roller (3) and the counter-bearing roller (4), and configured so as to ensure direct transmission of torque from the motorised roller (3) to the counter-bearing roller (4).
