Robotic cleaning devices, associated systems, and methods of using the same

A robotic device for cleaning a surrounding environment, the robotic device comprising:

• a body portion that defines at least a top surface, a bottom surface, and a continuous sidewall surface, wherein the sidewall surface is defined by a perimeter of the body portion;
• a large gear positioned within the body portion;
• a drive system that includes at least two drive elements configured to propel the robotic device within the surrounding environment, wherein the at least two drive elements extend a distance beneath the bottom surface;
• two or more bottom brushes having a primary axis of each brush that extends below the bottom surface and extend at least partially beyond the at least two drive elements to engage the surrounding environment;
• the continuous opening that extends around the sidewall surface, wherein the continuous opening is defined along the sidewall surface between the top surface and the bottom surface, and wherein the continuous opening extends purely horizontally around an entirety of the perimeter of the body portion;
• at least one sidewall brush that extends from the body portion and is configured to travel along the continuous opening and relative to the top surface and the bottom surface of the body portion;
• and
• at least one sidewall drive mechanism,
• wherein:
• each sidewall drive mechanism comprises:
• a connection rod
• a motor;
• and
• a small gear that is coupled to the motor and is configured to be rotatable by the motor, wherein the small gear is positioned such that gear teeth of the small gear mesh with gear teeth of the large gear, and
• each of the at least one sidewall brush is coupled to the respective connection rod of the respective sidewall drive mechanism,
• each sidewall drive mechanism is configured to orbit the respective sidewall brush around the body portion of the robotic device when the small gear is rotated by the motor.
