6. A blade assembly for working on a work surface/area/structure, the blade assembly including at least two blades, a first blade and a second blade that are axially aligned, each blade having a working portion at the periphery of the blade, and the working portions of two neighboring blades are spaced apart in an assembly axial direction, and the blade assembly further including a blade assembly central portion around the axial center of the blades for being operated on by a device for driving the blades, a blade assembly support structure extending between the working portion of the blades and the blade assembly central portion;
- the blades are spaced apart by a spacer structure/s, said spacer structure/s forming at least one compartment or passage between the blades extending essentially radial towards the working portion, and at least at one radius of the spacer structure/s the at least one compartment or passage covering a significant part of the periphery at that radius of the spacer structure/s, said compartment/s having at least one inlet, for air and/or liquid, being located between the working portion and the axial center of the blades, and the compartment/s or passage/s have at least one air vent on at least both outermost blades alone or in combination with at least one fluid inlet, wherein the at least one air vent and at least one fluid inlet are within a radius not exceeding a first fractional half of the blade radius, said air vent/s for sucking air into the compartments.

- 40. A blade assembly for working on a work surface/area/structure, the blade assembly including at least two blades, a first blade and a second blade, that are axially aligned, each blade having a working portion at the periphery of the blade and a central portion around the axial center of the blade for being operated on by a device for driving the blade assembly, a blade support structure extending between the working portion and the central portion characterized in that the blades are spaced apart by a spacer structure/s, including a central hub that provides support at the central portion, and a plurality of fan blade shaped supports that provides support at the blade support structure and functions as fan blades, said blade assembly having at least one air vent on at least both outermost blades, said air vent being within a radius not exceeding the first fractional half of the blade radius.
