Facility for washing a shopping trolley, in particular of a supermarket

The installation (2) has an enclosure (3) provided with a tube (9) for spraying a cleaning liquid within the enclosure. A partition (11) compartmentalizes the enclosure into two chambers (31, 32) arranged side by side, where each chamber includes inlet opening (7) and an outlet opening on the same side (6) of the enclosure for inlet/outlet of a shopping trolley (1). A drive control unit (10) controls the movement of the tube for spraying the cleaning liquid in the enclosure through another opening (12) that is closable in the partition compartmentalizing the enclosure.
