Claim 13:
14. A self-moving cleaning device, comprising:
a base;
a mobile module adjacent to the base and configured to contact a surface when the self-moving cleaning device moves on the surface;
a vacuum module arranged over the base;
a dust box arranged over the base and connected to the vacuum module, the dust box comprising a first opening and a second opening, wherein the first opening is oriented in a first direction different from a second direction in which the second opening is oriented;
a first suction port arranged on the base and comprising a first suction inlet connected to the first opening, wherein the first suction port is free of any bristle or brush blade;
a second suction port arranged on the base and comprising a second suction inlet connected to the second opening, the first suction port disposed between a front side of the base and the second suction port;
a roller brush device arranged on the base and within the second suction port; and
an air duct, wherein the first suction port is connected to the dust box through the air duct to thereby connect the first suction inlet to the first opening,
wherein
the first opening is disposed over the roller brush device, and the first opening is disposed over the second opening;
wherein the dust box comprises:
a front side wall;
a bottom surface; and
an inclined surface between the front side wall and the bottom surface, wherein the second opening is arranged on the inclined surface;

wherein a first included angle is formed between the first opening and the bottom surface, and a second included angle is formed between the second opening and the bottom surface of the dust box, wherein the first included angle is greater than the second included angle;
wherein the air duct extends, conformal to a shape of a sidewall of the second suction port of the base, from the first suction port to a location over the roller brush device, thereby connecting the air duct to the dust box,
wherein a shape of the inclined surface corresponds to a wall of the air duct and conforms to the shape of the sidewall of the second suction port, and the dust box and the second suction port are arrangement in a compact manner.
