A rotating grooming brush comprising a brush hub having grooming elements and shroud elements, and method for grooming a surface having an unwanted material thereon. The elements extend from the brush hub and may be positioned near its outer periphery. The elements may be grooming elements forming an array and shroud elements forming a shroud array. A rigid or elastomeric shroud extending from the brush hub surface may optionally be included about the edge of the brush hub, to the outside of the grooming elements. Rotation of the grooming attachment brush causes a low pressure region to build in the central area of the brush. This low pressure region creates a resulting force that forcefully attracts the grooming attachment brush to the surface to be groomed. The resulting force is controlled by the diameter of the brush hub, arrangement, of the elements and the speed of rotation.

The dynamic testing of materials in moving solutions, such as anti-fouling paint in seawater, is conducted in a cylindrical tank. A stirrer having a drive shaft and one or more paddles or blades is driven by a variable speed motor to rotate and to impart rotational velocity to a liquid, which passes over the test materials which are attached to the periphery of the tank. The flow conditions over the surface can be well characterized. The surface of the test materials may be instrumented to measure physical, chemical and hydrodynamic conditions. The energy required for testing is reduced over prior art techniques.
