PROBLEM TO BE SOLVED: To provide a cleaning robot to prevent a suction member from moving upwards when the suction member is rotated during a collision with an obstacle, to completely unfold the suction member when the suction member travels on an uneven surface such as a carpet, and further to automatically fold and unfold the suction member. SOLUTION: A torsion spring for connecting an elevating member 44 and a suction member 50 rotates the suction member 50 within a range of elastic deformation, when a suction arm 51 collides with the obstacle, the suction arm is folded toward the body side, and after passing the obstacle, the suction arm 51 is unfolded by elasticity of the torsion spring. A coil spring 49 allows the suction member 50 to move upwards and downwards depending on a change of a height of the surface to be cleaned while the cleaning robot 49 travels on the uneven surface. At this time, a guide knob 45 move upwards together with the elevating member 44, thereby separating from the rotation guide face, and the suction arm 51 can be maintained in a completely unfolded state.

Abstract:
PROBLEM TO BE SOLVED: To provide a self-propelled cleaner reducing load received by a brush mechanism from a floor face and preventing a cord or the like from being twisted around the brush mechanism to hinder self-propelled motion of the self-propelled cleaner provided with a self-propelled mechanism and a cleaning mechanism at a cleaner body 1 and cleaning the floor face by the cleaning mechanism while moving on the floor face by the self-propelled mechanism. SOLUTION: In this self-propelled cleaner, the cleaning mechanism is composed of the brush mechanism 5 rotatable along the floor face, and a drive mechanism 4 for rotationally driving the brush mechanism 5. The brush mechanism 5 is composed of a rotating shaft 51 extending vertically to the floor face, one arm 52 projecting sideways from the lower end of the rotating shaft 51, and a brush 53 planted in the arm 52.

Abstract:
PROBLEM TO BE SOLVED: To improve dust collecting force by preventing the scattering of dust in a self-propelled cleaner provided with side brushes for gathering the dust on a floor surface to the inner side of a cleaner body on both sides of the cleaner body. SOLUTION: By inclining the rotary shaft 31R of a right side brush 30R to be rotated in the counterclockwise direction r1 in top view such that a lower end side 31a is turned to the right outer part and rear part of the cleaner body 1 and inclining the rotary shaft 31L of a left side brush 30L to be rotated in the clockwise direction r2 in top view such that the lower end side 31a is turned to the left outer part and rear part of the cleaner body 1, the outer side parts of the side brushes 30R and 30L are prevented from being in contact with the floor surface at the rear parts of the side brushes 30R and 30L. Thus, the dust raked at the front parts of the side brushes 30R and 30L is not raked out to the outer side of the cleaner body 1 at the rear parts of the side brushes 30R and 30L.

Abstract:
PROBLEM TO BE SOLVED: To provide a robot cleaner which automatically travels around a predetermined area while performing vacuum and/or air cleaning by a negative ion at the same time or selectively. SOLUTION: The robot cleaner includes a robot cleaner body, a driving unit to drive a plurality of wheels mounted on the lower part of the robot cleaner body, a dust suction unit to suck dust on a floor, a negative-ion generation unit mounted in the robot cleaner body to generate a negative-ion, and a control unit. While the robot cleaner automatically travels on a surface to be cleaned, the robot cleaner performs vacuum cleaning using the dust suction unit, and air cleaning using the negative-ion generation unit, either at the same time or selectively.
