Abstract
A mobile collection device including a vehicle assisted working device for cleaning surfaces, and an autonomously self-driving robot vehicle. The working device includes a brush for detachment of extraneous material from the surface, a blower configured to provide an underpressure for a suction of the detached material into the air flow from the surface, and a cyclone configured to separate material from the air flow. The blower is configured to provide an overpressure and return of the separated air to the surface. The brush is configured to rotate counter-wise to a forward movement direction of the working device. The working device is configured such that the spot is treated in the following order: the blower provides the underpressure for the suction of the detached materials, the counter-rotating brush brushes the spot, and the blower provides the overpressure and return of the separated air to the surface via an air-knife.
