Abstract
The product efficacy apparatus includes a roller having an outer surface and a test bed having a test surface. The roller may be affixed to a rotatable shaft having opposing end regions. The shaft may be rotatably connected to an arm at each end of the end regions of the shaft. Each arm is pivotally connected to a drive member that is rollingly connected to a stationary track. In operation, a cleaning product may be affixed to the outer surface of the roller. A controlled insult may be applied to the test surface. The arms pivot toward the test surface in order to direct the cleaning product on the outer surface of the roller into contact with the test surface. The drive members direct the roller over the controlled insult. The shaft rotates the roller over the test surface and the arms pivot the roller away from the test surface.
