<p>An apparatus is provided for cleaning a surface (5), the apparatus including a plurality of water absorbing flexible washing layers (10) positioned and secured in a vertical stack (20). The bottom layer (30) in the stack (20) has the smallest surface area of the plurality of layers (10), and each successive layer (10) from the bottom to the top of the stack has a successively larger area. A binding means (80) secures the layers (10) together at a central portion (15), thus forming an integral assembly in which peripheral portions (18) of the layers (10) can move freely. The layers (10) are constructed of a material formulation of approximately 30 % viscose material and 70 % synthetic fiber in a density of approximately 400 grams per square meter and a thickness of approximately 2.6 mm. Each layer (10) preferably has a plurality of cuts (40) that defines fingers (50) on the peripheral portion (18) of the layers (10).</p> |
