Abstract
A robotic vacuum wherein the housing of the system is cylindrical in form with two wheels of diameter larger than the diameter of the housing supporting the housing on either end. Larger wheels permit the device to more easily travel over small bumps or obstacles and changes in elevation. Furthermore, the design requires less power to drive the housing, so more energy is available for the primary function of vacuuming.
