Abstract
A method for increasing the rate of debris collection of a robotic vacuum through increasing the number of times a robotic vacuum's cleaning apparatus passes over a work surface during each pass of the device. The device's main cleaning apparatus is installed on a plate that rotates within the housing of the device. The drive unit is housed separately from the rotating plate so that the device's normal movement patterns will be uninterrupted by the rotation of the cleaning apparatus. Ideally, the cleaning apparatus will be caused to rotate two or more times over an area before the robotic vacuum has driven completely through the area.
