Abstract: A vehicle assisted working device for cleaning streets and similar surfaces includes at least one brush for detachment of the extraneous material from the surface, element for providing an underpressure for a suction of the detached material into the air flow from the surface, units for separating the detached material from the air flow and for providing an overpressure and return of the separated air to the surface. At least one brush is arranged to rotate counter-wise to the intended direction of movement of the working device, so that the element are ordered in such a way that when the working device is intended to move over a spot to be cleaned, it treats the spot in the following order: suction of the extraneous materials, at least one brush and mechanism for return of the separated air to the surface. Also disclosed are a system and method for cleaning.

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.
