Abstract: A wheel for an autonomous cleaning robot that maneuvers the robot on a floor surface includes a tire having first and second opposing outer edges and a middle portion having a tread pattern between the first and second outer edges, the tread pattern comprising a plurality of raised tread having trenches therebetween. Each of the plurality of raised tread includes a first raised tread portion extending from the first outer edge to the middle portion and substantially perpendicular to the first and second outer edges; a second raised tread portion extending at an angle away from the first raised tread portion; and a third raised tread portion extending from the second raised tread portion to the second outer edge and substantially perpendicular to the first and second outer edges, the third raised tread portion being laterally offset from the first raised tread portion.
