ABSTRACT:
A vacuum tool for delicate dusting of plants and similar delicate fabrics has an inner and outer shell. The inner shell has a distribution of holes providing even volume of air flow per unit length of inner and outer shells. The outer shell has an even distribution of holes which provide even volume of air flow and air velocity per hole and also even suction over the outer shell. The outer holes are sunk within grooves so that fabric, leaves and petals and the like are not sucked against the holes and torn, ripped or frayed. The grooves also provide even suction over the surface of the outer shell.
