  • the invention relates to a cleaning device, comprising a base body to which at least one cleaning body is assigned on the underside facing the floor to be cleaned, the cleaning body being rotatably mounted on the base body about an axis of rotation, the axis of rotation of the cleaning body being perpendicular to the underside of the base body is aligned.
  • the base body advantageously also has a device by means of which the base body can be moved over the floor to be cleaned.
  • the device can include rollers or rollers.
  • the rollers or rollers can also be driven by an electric motor.
  • a handle can be attached to the base body with a handle.
  • the cleaning device can be for autonomous cleaning.
  • Cleaning devices are known from the prior art in which cleaning bodies are rotatably mounted on the underside of the base body, the axis of rotation being oriented perpendicular to the underside.
  • the cleaning bodies are mostly assigned to the front corners of the base body. Due to the rotatable mounting of the cleaning bodies, the cleaning surfaces of the cleaning bodies are mostly designed to be rotationally symmetrical, that is to say circular. This configuration results in the problem that corners of the floors to be cleaned cannot be reached by the cleaning bodies, so that dirt can collect there.
  • Tasks are known from the prior art in which cleaning bodies are rotatably mounted on the underside of the base body, the axis of rotation being oriented perpendicular to the underside.
  • the cleaning bodies are mostly assigned to the front corners of the base body.

This configuration results in the problem that corners of the floors to be cleaned cannot be reached by the cleaning bodies, so that dirt
  • the invention is based on the object of further developing a cleaning device of the type mentioned at the beginning in such a way that the cleaning device has an improved cleaning effect.
  • the cleaning body is mounted in the base body in such a way that the axis of rotation can be moved relative to the underside during the cleaning work along a movement path oriented perpendicular to the axis of rotation.
  • the axis of rotation of the cleaning body is moved relative to the base body during the cleaning work.
  • the cleaning body is mounted in the base body in such a way that it does not have a fixed axis of rotation, i.e. a fixed axis of rotation relative to the base body.
  • the cleaning body can rotate in such a way that corner areas can be reached more easily.
  • the axis of rotation preferably moves along a circular path.
  • the cleaning body wobbles with its axis of rotation along the circular path, the cleaning body also executing a superimposed lateral movement relative to the floor to be cleaned in addition to a rotational movement.
  • the superimposition of a rotation and a sideways movement improves the cleaning result.
  • a movement of the cleaning device can be superimposed, e.g. by moving or moving the cleaning device on the surface to be cleaned.
  • the cleaning body can be provided with a cleaning pad, the cleaning pad having a cleaning surface which is circular in shape has a different shape.
  • the cleaning surface has a smaller radius in at least one area than the circumferential circle delimiting the cleaning surface.
  • the cleaning surface can be pointed in one area.
  • the cleaning surface is essentially circular, but deviates from the circular shape in at least one area.
  • the cleaning surface can also have a polygonal shape. In connection with the variable axis of rotation, the shape of the cleaning surface can be selected in such a way that the cleaning result is improved, especially in corners.
  • the cleaning surface is designed as a polygonal uniform thickness. If the cleaning surface is designed as a polygonal uniform thickness, the opposing edges of the cleaning pad are equidistant from one another at every point. In this respect, the circumferential edge of the cleaning pad forms a curve of constant width. Due to the polygonal design, the cleaning surface deviates from the circular shape. Due to the design as a uniform thickness, the cleaning pad is particularly suitable for cleaning corner areas that are difficult to reach.
  • the cleaning surface of the cleaning pad is designed as a Reuleaux triangle.
  • a Reuleaux triangle is a constant thickness in which the distance between each point on one side and the opposite corner is constant. The constant width is retained when rotating around the center of the area.
  • the cleaning result is improved.
  • the circular movement of the axis of rotation and the movement of the cleaning pad can be coordinated such that the tips of the triangular cleaning pad also reach inaccessible corner areas of the floor to be cleaned.
  • the cleaning body can be set in motion by means of a drive device, the drive device comprising a gear arrangement.
  • the gear arrangement is designed in such a way that both the cleaning body is in rotation is offset as well as the deflection of the axis of rotation takes place.
  • the gear arrangement can for example comprise a cardan joint or a spring shaft.
  • the gear arrangement is preferably designed as a gear drive.
  • Gear drives are inexpensive and robust.
  • the base body can be assigned a first gear with internal teeth, which is arranged in a fixed position in the base body.
  • a second gear with external teeth rolls in the first gear.
  • the diameter of the second gear is smaller than the inner diameter of the first gear.
  • the axis of rotation of the second gear moves along a circular path.
  • the gear rotates about its axis of rotation.
  • the cleaning body is in turn fixed to the second gear and also moves about its axis of rotation.
  • the cleaning body describes a superimposed tumbling and rotational movement. In connection with the triangular configuration of the cleaning pad, this results in an area over which the cleaning pad sweeps and which is almost rectangular. This enables the cleaning pad to also reach corners of the room.
  • the drive device can comprise an electric motor. This results in a particularly high cleaning performance and an energy-saving cleaning work.
  • the electric motor is preferably supplied with energy via an accumulator arranged in the cleaning device.
  • the cleaning device can be designed as a cleaning robot. As a result, the cleaning device can carry out cleaning work autonomously.
  • the inventive design of the cleaning body results in a particularly thorough cleaning.
  • the main body preferably comprises two cleaning bodies. Further preference, the cleaning body are each a corner area of the front edge of the Assigned to the base body. Furthermore, the cleaning bodies preferably protrude laterally from the base body, at least in sections. This results in particularly effective cleaning.
