1. A robotic cleaning device comprising:

  • a main body having;

    a wheel axis extending in a lateral direction,a drive axis extending perpendicular to the wheel axis,a front end portion located in front of the wheel axis,a rear end portion located behind the wheel axis,a first perimeter sidewall extending along and connecting the front end portion and the rear end portion on a first side of the drive axis,a second perimeter sidewall extending along and connecting the front end portion and the rear end portion on a second side of the drive axis,a laterally protruding member extending from the first perimeter sidewall along the lateral direction in the front end portion of the main body,wherein the main body has a generally triangular shape defined by a width (A) and a width (B),wherein width (A) is a greatest width of the main body as defined between an outermost point of the laterally protruding member and a point on the second perimeter sidewall located in the front end portion, and width (B) is a width of the main body as defined between the outermost point of the laterally protruding member and a point on the second perimeter sidewall located in the rear end portion, where width (A) is greater than width (B);

    at least one driving wheel arranged on the main body on the wheel axis and configured to movably support the robotic cleaning device on a surface to be cleaned;

    a cleaning member including an opening in the main body arranged at a bottom side in the front end portion of the main body for removing debris from the surface to be cleaned; and

    a brush arranged at a bottom side of the laterally protruding member for removing debris from the surface to be cleaned.
