Underwater cleaner

Abstract

The invention relates to an underwater cleaner having a housing in which a pump, in particular a battery-operated pump, with an electric motor and an axial impeller rotatable about an axis of rotation is arranged, having a suction nozzle formed by the housing with a suction mouth defining a suction plane and a flow channel which is arranged in the housing accommodates the axial impeller and extends between a channel inlet opening arranged in the region of the suction nozzle and a channel outlet opening, wherein a receptacle for a filter device is arranged in the region of the channel outlet opening, and wherein the flow center axis of the flow channel is arranged perpendicular to the suction plane in a first section having the channel inlet opening and parallel to the suction plane in a second section having the channel outlet opening, and wherein the axial impeller is arranged in the first section of the flow channel, and wherein a first distance between a reference plane tangent to a lower channel wall of the second section normal to the axis of rotation of the axial impeller and the suction plane is smaller than the impeller radius. A compact underwater cleaner with a high suction effect can be realized if the reference plane intersects the axial impeller in at least one region of the impeller blades and at least one impeller blade projects beyond the reference plane by a defined projection.
