Abstract: A robot cleaner includes a body, a first rotating plate, a second rotating plate, a first mop, a second mop, a first support wheel, a second support wheel, and a first lower sensor. The first lower sensor is configured to sense a relative distance from a floor. The first lower sensor is located between the first support wheel and the second support wheel, and is located further away from the first rotating plate and the second rotating plate than the first support wheel and the second support wheel. The robot cleaner may move while being supported by the first mop, the second mop, the first support wheel, and the second support wheel, and easily avoid a cliff in which the floor suddenly drops.

Abstract: A cleaner is provided. The cleaner includes a body, a first rotating plate, a second rotating plate, a first mop, a second mop, a support wheel, and an auxiliary wheel. The lowest parts of the first rotating plate and the second rotating plate are higher than a virtual reference line connecting the lowest part of the support wheel to the lowest part of the auxiliary wheel, and the lowest parts of the first mop and the second mop are lower than the reference line. The cleaner can prevent the first rotating plate, the second rotating plate, and the floor from being damaged while mopping of the floor is performed by the first mop and the second mop.
