Definitions

  • the present invention relates to a hand-held floor cleaning machine for cleaning a floor surface with a base on which a cleaning device is provided which has at least one driven brush element which is designed to engage in a cleaning plane with a floor surface to be cleaned and to support the base relative to the floor surface, and with an operating bar which is pivotally mounted on the base and extends away from the base, an application device for applying cleaning liquid to the floor surface to be cleaned being provided on the base and a suction cup being held and designed on the base via a holder is to absorb dirty liquid from the floor surface to be cleaned.
  • a cleaning device is provided on a base, which has one or more driven brush elements which are designed to engage with the floor surface to be cleaned and thereby remove dirt from it.

  • an application device is provided with which cleaning liquid is brought into the area of the brush elements, so that the loosening of dirt is improved.
  • a suction cup is articulated directly on the base and is connected to a dirty liquid container in the base or the operating handle. With the suction cup, dirty liquid can be picked up again from the floor surface to be cleaned by means of a negative pressure that can be generated in the dirty liquid container by a suction device.

This ensures that the guide wheel always rests on the floor surface to be cleaned, regardless of the height of the brush elements.
  • a biasing device can be provided which biases the first pivot arm so that its free end is pressed towards the cleaning plane in which the free ends of the brush elements are located. This presses the guide wheels against the floor surface to be cleaned.
  • the biasing device can have a spring which is arranged between the base and the first pivot arm.
  • a second pivot arm is pivotally connected to the first pivot arm of the one or more holders, which in turn holds the suction cup. Due to the pivotability of the second pivot arm relative to the first pivot arm, the vertical position of the suction cup can change relative to the guide wheels.

That the entire load of the squeegee must be supported by the suction lips.
  • This guide element is preferably provided in the middle of the suction cup.
  • a stop is provided on the first or the second swivel arm, the stop being designed to limit a swivel movement of the first swivel arm relative to the second swivel arm away from the base. This prevents the suction cup from pivoting too far below the level defined by the contact surface of one or more guide wheels.

  • the spring 69 ensures that the guide wheels 49 always rest on the floor surface 5 to be cleaned, regardless of the extent to which the brush elements 7 are worn or how far they extend downwards from the base 3. Because the guide wheels 49 rest reliably on the floor surface 5 to be cleaned, a straight-line movement of the base 3 along the direction of movement 21 is possible without any problems.
  • the suction base 23 can vertically avoid obstacles due to the pivotability of the second pivot arms 51 and also rests reliably on the floor surface 5 to be cleaned, this being additionally ensured here by the wheels 34.
