Abstract: A device for a scrubbing-liquid scraper ring for a wet-scrubbing machine having a motor-driven rotatable brush. The scraper ring includes a plurality of flexible blade members that are tilted in relation to the ring's circumference and intended rotational direction and that are held in place in the scraper ring by respective quick-attachment mechanisms. A quick-attachment mechanism includes a manual actuation part and an attachment part that cooperates with a respective flexible blade member, and the attachment part is configured to move between a holding position and a releasing position.

Abstract: The invention relates to a fluid system (50) for cleaning machine (1), which comprises a floor treating brush and/or disc (7) rotatably driven by a motor (4) and exhibiting surrounding ring-shaped rim (8) and conduit for washing liquid and vacuum suction duct for the supply (11) of washing liquid (12) and suction (13) of washing liquid (14), respectively. A disc-shaped bottom part (25) provided with substantially radially extending vacuum suction ducts (24) is located above said rotatable brush and/or disc (7). A bottom cover (51) is connected to said bottom part (25), and nozzles (27) are connected to said vacuum ducts (24) along the periphery of said bottom part (25) and bottom cover (51) in order to suck up dirty washing liquid (14). Said bottom cover (51) and said bottom part (25) can be released from one another in order to reach said substantially radial vacuum suction ducts (24) located between them (25, 51).

Abstract: The invention relates to a driving system (6) for a cleaning machine (1), which comprises a floor treating brush and/or disc (7) rotatably driven by a motor (4) and exhibiting surrounding ring-shaped rim and vacuum duct (10) for suction (13) of washing liquid (14). According to the invention the motor is formed by a horizontally arranged, electrically driven hub motor (4). The rotor (15) of the motor (4) is drivably connected to said rotatably driven floor treating brush and/or disc (7), while the stator (17) of the motor (4) is connected to the stationary frame (18) of the cleaning machine (1).

Abstract: The invention relates to a liquid wiper device formed of a circular obstacle and intended for a floor cleaning machine that operates with liquid and has a scrubbing-brush that is rotatably driven around a vertical shaft by a motor and arranged and intended for the scrubbing of floors and similar surfaces. According to the invention, the device is formed of ring pieces that are interconnectable into a ring shape and have wiper strips carried thereby. The wiper strips have a thickened upper fastening end portion while the remaining part of the wiper strips has essentially a plate shape. The wiper strips have essentially a T-shaped cross-sectional profile, said ring pieces having a number of recesses distributed along the length extension thereof, and the wiper strips are received in and retained by the same.

Abstract: The invention relates to a device (1) in connection with a floor cleaning machine functioning with liquid. According to the invention a combined hub (5) for supporting a brush/disc (6) of a floor cleaning machine has three functions, viz. A: as a hub for a brush/disc for holding the same, B: as a distributor for the distribution of liquid to said machine, radially from the outside towards the centre of the hub, and C: as a distributor for the distribution of vacuum to said machine in order to suck up washing liquid from the machine.
