Abstract
An autonomous cleaning device (1), such as a robotic vacuum (1), has an optical sensor (50) that includes: a rotary body (51) configured to rotate relative to a main body (2) about a rotational axis (CX); a light-emitting device (61) provided on the rotary body; a light-receiving device (62) provided on the rotary body; a cover (52) disposed upward of the rotary body; and legs (70) disposed around the rotary body and supporting the cover. In a cross section orthogonal to the rotational axis, at least a portion of a surface of each of the legs is inclined with respect to a virtual radial line (RL) extending in the radial direction of the rotational axis.
