The invention relates to sine sweeping machine for carpets and the like. With at least one motor-driven brush roller or the like which can be rotated parallel to the sweeping plane and partially protrudes from a housing of the machine, the roller about a distance from its axis of rotation and parallel to it. this lying pivot axis is pivotably mounted, and is loaded with at least its weight towards the Kenrebene.

This type of storage of a brush roller is known so far in a carpet knocking machine, in which the brush roller is moved to and away from the carpet in a pivoting oscillating manner about the pivot axis. ' In a beating machine of this type, the brush roller is mounted on two one-armed legs that are pivotably attached to the housing of the beating machine. "The brush roller is driven by a drive motor that is rigidly attached to the machine housing measured as precisely as possible lie in the pivot axis of the single-arm planer, because otherwise during the pivoting movement

housing at least / is connected to which the is mounted. Through this formation, the motor forms a structural unit for the bearing arms for the brush roller and the hinge, which can be buried as a whole around the pivot axis. As a result, the brush roller is weight-loaded towards the sweeping plane, so that it presses on the surface of the surface with a force corresponding to this weight.

According to another Merkisal of the invention, the drive «

motor / brush roller designed as a blower motor for sucking out the dirt. As a result, the sweeping machine according to the invention can be kept comparatively small in terms of its dimensions, with the susceptibility to malfunction being reduced compared to known devices with several motors.

In a further embodiment of the invention, there is the GehSuso from an upper part and a lower part, whose outward formed edges of a preferably U-profile «= - fUrad, gen
