Abstract

A device for cleaning floors with the aid of a liquid comprising: a hollow, elongated suction mouth piece having a longitudinal axis and having an elongated suction port extending along the lower surface thereof parallel to said longitudinal axis, a suction tube connected to the mouth piece and communicating at one end with the interior of the mouth piece, the suction tube having an opposite end for connection with a suction device; a spray nozzle mounted adjacent each end of the elongated suction mouth piece, said nozzles being directed downwardly and inwardly toward each other.

Claims

1. Device for cleaning floors with the aid of a liquid, said device comprising a tube, said tube at its one end being in communication with a suction device and at its other end opening into an elongated suction mouth-piece, and a conduit, which at its one end is in communication with the source of a cleansing fluid under pressure and at its other end is in communication with at least one spray nozzle, said nozzle being mounted at a fixed position above the suction port of the suction mouth-piece and being directed towards a point lying beyond one of the long sides of the suction mouth-piece, characterized in that two spray nozzles are mounted adjacent the small sides of the suction mouth-piece, said spray nozzles being directed to each other obliquely inwardly.

2. Device in accordance with claim 1, characterized in that the mouth-piece is rotatably mounted on the suction tube.

3. A device for cleaning floors with the aid of a liquid comprising:

a hollow, elongated suction mouth piece having a longitudinal axis and having an elongated suction port extending along the lower surface thereof parallel to said longitudinal axis;

a suction tube connected to the mouth piece and communicating at one end with the interior of the mouth piece, the suction tube having an opposite end for connection with a suction device;

a spray nozzle mounted adjacent each end of the elongated suction mouth piece, said nozzles being directed downwardly and inwardly toward each other; and

conduit means for supplying liquid to the nozzles.

4. A device as in claim 3 wherein said mouth piece is straight and wherein said nozzles are offset from said mouth piece in a transverse direction.
