摘要： A vacuum cleaner includes: a body case having an outer circumferential surface formed along either a circular arc or a polygon; a drive wheel allowing travel of the body case on a cleaning target surface; a side brush provided to the body case to be movable in a certain direction. The side brush: projects from the outer circumferential surface of the body case by an amount that changes in response to movement; includes a brush body movable to retreat toward the outer circumferential surface of the body case in response to external force acting in a direction crossing the certain direction; and includes a cleaning unit rotatably provided to the brush body. The cleaning unit rotates to clean the cleaning target surface. The side brush projecting from an outer circumferential surface of a body case can retreat readily and reliably when the side brush contacts an obstacle.

摘要： A vacuum cleaner includes a main casing, driving wheels, side brushes, an obstacle sensor, and a controller. The driving wheels enable the main casing to travel. The side brushes are reciprocatively movable in both a direction of protruding from an outer frame of the main casing and its opposite direction, enabling cleaning of dust and dirt located outside the outer frame of the main casing. The obstacle sensor detects an obstacle by detecting a movement of the side brush in the opposite direction due to its contact with the obstacle. The controller controls drive of the driving wheels based on detection of an obstacle by the obstacle sensor to make the main casing autonomously travel. The vacuum cleaner can detect an obstacle at a position of a side brush while securely cleaning dust and dirt located outside an outer frame of a main casing by the side brush.

摘要： An electric vacuum cleaner includes a main body case, driving wheels, and a cleaning portion. The main body case includes an electric blower, and a dust collecting portion communicating with a suction side of the electric blower. The driving wheels allow the main body case to travel on the surface to be cleaned. The cleaning portion includes a main body portion, the suction port, and wheels. The main body portion with a bottom surface portion facing the surface to be cleaned is located in a lower portion of the main body case and can move up and down. The suction port is provided on the bottom surface portion and communicates with the dust collecting portion. The wheels protrude downward from the bottom surface portion to contact the surface to be cleaned, thereby causing the main body portion to move up and down to trace the surface to be cleaned.

摘要： A vacuum cleaner includes link mechanisms that connect a bumper to be movable in a relatively horizontal direction with respect to a case main body. A coil spring energizes the bumper in a direction separated from the case main body. Obstacle sensors are arranged at positions facing the bumper in the case main body, and detect an obstacle by detecting movement of the bumper, due to contact with the obstacle, in at least one of a direction opposite to an energizing direction of the coil spring and a direction crossing such a direction. A controller controls the drive of a driving wheel based on detection of the obstacle by the obstacle sensor to allow the main body case to travel autonomously. The vacuum cleaner can detect an obstacle brought into contact with the bumper in a wide range with a simple configuration.

摘要： A vacuum cleaner capable of ensuring communication between a suction port and a dust collecting unit even in a state that a body portion of a cleaning unit has pivoted along an up/down direction relative to a main casing. The body portion is provided on the main casing to be pivotable along the up/down direction. A sliding-contact surface portion is provided in the body portion and curved along a pivoting direction of the body portion. A curved surface portion is provided in the communicating section body and curved along the pivoting direction of the body portion to be brought into sliding contact with the sliding-contact surface portion by pivoting motion of the body portion. A communicating opening is opened in the curved surface portion to communicate with the dust collecting unit.
