Abstract: A water suction apparatus for scrubbing machines having a non-rotatable frame (11), a rotatable scrubbing-brush (1 a) and a rotatably driven holder (1) therefore. The holder has a ring (7) around its periphery, the ring being provided with nozzles (2) which have lower ends in gliding contact with or positioned immediately above the floor and which suck dirty scrub water therefrom, the ring also being provided with lips (5) which are located between the nozzles and have lower ends in gliding contact with the floor and which transmit dirty scrub water to the nozzles when the ring rotates. The frame (11) has a ring (4) connected thereto which sealingly cooperates with the rotatable ring (7) on the holder (1) and which is provided with at least one nozzle (6) which is connected to a conduit (12) transmitting dirty scrub water from the nozzles (2) on the rotatable ring to a water separator or the like.

Abstract: An apparatus for the wet cleaning of floors and similar surfaces by use of a round rotating scrubbing brush powered by a motor. The brush has a centrally mounted outlet for dispensing clean water onto the floor to which detergent of a suitable kind is added. Surrounding the scrubbing brush is mounted an annular, non-rotating suction nozzle for removing dirty cleaning water from the floor. The nozzle is provided with radial openings, some of which are located at its inner circumference and oriented inwardly towards the scrubbing brush, and the remainder being located on the outer circumference and oriented outwardly towards a space arranged outside and around the nozzle. In the upper part of this space is mounted a ring, rotated by the motor, and provided with a plurality of openings for dispensing rinsing water, the openings being oriented towards the floor.
