Claim Text:
1. A device for removing dirt from a floor, comprising: a carrier frame moveable over the floor, a motor mounted on the carrier frame, a rotating body rotatable in one direction of rotation about a first substantially horizontal rotation axis and connected with the carrier frame, the rotating body being drivable by the motor, several shovel-holders for shovelling the dirt from the floor, the shovel-holders are mounted on the rotating body spaced apart from each other in the peripheral direction and the shovel-holders on rotation of the rotating body move along a path which runs at least partly along the floor, and the shovel-holders each comprise a trough-shaped wall which delimits an internal receiving cavity for receiving the shovelled dirt, and the shovel-holders each comprise an open end which is substantially oriented in the rotation direction of the rotating body, a sweeper device for sweeping the dirt in each case out of one of the shovel-holders on rotation of the rotating body, the sweeper device is arranged along the path of the shovel-holders on the carrier frame at a position which is substantially stationary in relation to the carrier frame, the sweeper device is fitted with a sweeper element that is moveable and driveable such that the sweeper element, on rotation of the rotating body, for each shovel-holder which passes the sweeper device, moves from a starting position outside the path of the shovel-holders into the path of the shovel-holders, through the open end of the passing shovel-holder into the internal receiving cavity of the passing shovel-holder and then on through the internal receiving cavity of the passing shovel-holder in order to sweep out at least a quantity of the dirt shovelled up by the passing shovel-holder, and the sweeper element then moves out of the passing shovel-holder and then away out of the path of the shovel-holders in order to allow the passing shovel-holder to pass by the sweeper device.
