A submergible cleaning device (1) comprising a frame (2) and at least one cleaning unit (5) attached to the frame (2). The cleaning units comprises: a housing (6) defining a lower edge (7) extending about an opening (8) into an inner cavity (9), an outlet (10) through a surface (11) of the housing, a power-driven pumping arrangement to provide a fluid flow from the cavity through the outlet (10), a water injection system with at least one nozzle (12), a rotary disc (13) defining an outer surface (14) and on opposite inner surface (15) and arranged in the opening (8) with the inner surface (15) facing the cavity (9), the rotary disc (13) being arranged for rotation about a rotor axis (16) and carrying the at least one nozzle (12) to thereby generate a circulating flow of water during rotation, and power-driven means (17) arranged to rotate the rotary disc about the rotor axis (16). To provide better flow conditions from the cavity into the outlet and thereby to enable a reduced power-driven pumping and thereby reduces suction, better manoeuvrability, and reduced power consumption, the radial distance from the outlet (10) to the rotor axis (16) is larger than a radial distance from a periphery (17) of the rotary disc (13) to the rotor axis (16).
