1. A cleaning apparatus comprising:
a handle comprising a first handle portion; three individual neck elements, wherein the individual neck elements each include a first neck end and a second neck end opposite the first neck end, and wherein the second neck ends of the individual neck elements are coupled to the first handle portion; and a composite cleaning head comprising three individual cleaning heads, wherein each of the individual cleaning heads includes a longitudinal plane, a longitudinal axis, a lateral plane, top and bottom sides and a proximal portion connected to the first neck end of one of the individual neck elements and an opposing distal portion, wherein each of the individual cleaning heads includes at least one cleaning tool coupled to its bottom side, and wherein at least one of the cleaning tools of each individual cleaning head includes at least one of bristles, fibers, hair, filaments, wires, wool, abrasive material, pads, sponges, or a combination thereof; wherein the individual cleaning heads are disposed in a side-by-side, laterally adjacent arrangement, and the portions of the cleaning tools which contact a surface to be cleaned have a longitudinal profile substantially flat when in a non-stressed position, facing in substantially the same direction with respect to the lateral plane of the composite cleaning head; and wherein the composite cleaning head is configured to deform responsively and reversibly along its longitudinal plane in response to pressure applied in the direction of a surface to be cleaned, such that the cleaning tools contact concave, convex, other non-planar surfaces, and regular and irregular planar surfaces. |
