PROBLEM TO BE SOLVED: To provide an automatically traveling floor cleaner, and to provide an operation method for the same.SOLUTION: A floor cleaner can overcome an obstacle by traveling in a traveling direction at right angles or acute angles to the longitudinal direction of the obstacle which typically has a low rising obstacle surface with a height like that of a carpet rim. Furthermore, the floor cleaner (1) includes means for obstacle detection. In order to improve the floor cleaner and the operation method, the floor cleaner (1) executes traveling procedures for cleaning the obstacle or an area near the same, and the floor cleaner (1) takes in the relation to the obstacle surface, a traveling direction (R or V) along the longitudinal direction of the obstacle. In the traveling procedures, the boundary edge of the floor cleaner along the traveling direction performs traveling on a floor area in front of the obstacle with a horizontal direction distance from the obstacle surface. The distance is shorter than a distance (b) corresponding to the width of the floor cleaner (1) in a direction perpendicular to the traveling direction.
Abstract:
This electric vacuum cleaner has a vacuum cleaner main unit housing an electrically powered fan (18). The electric vacuum cleaner has an air trunk in communication with the suction side of the electrically powered fan (18). The electric vacuum cleaner is movable upon a surface to be cleaned, and has a floor brush (23) dividing a portion of the air trunk. The electric vacuum cleaner has an optical sensor (53) which detects the amount of dirt and dust passing within the air trunk as a result of operation of the electrically powered fan (18). The electric vacuum cleaner has a cleaning efficiency calculation unit (59) for calculating cleaning efficiency on the basis of the accumulated amount of the amount of dirt and dust which has been detected by the optical sensor (53), the amount of movement upon the surface to be cleaned of the floor brush (23), and the amount of time of the movement upon the surface to be cleaned of the floor brush (23). The electric vacuum cleaner has a display means (20) capable of displaying the cleaning efficiency which has been calculated by the cleaning efficiency calculation unit (59).

PROBLEM TO BE SOLVED: To reduce time to return a self-propelled vacuum cleaner having a rechargeable battery to a charging stand by quickly detecting a direction where the charging stand is present in a case such as where the self-propelled vacuum cleaner needs to be charged.SOLUTION: A self-propelled electronic device is configured to receive power supply from a charging stand placed at a predetermined position and to automatically travel to positions away from the charging stand. The self-propelled electronic device includes: a travel control part that controls the rotation of wheels and automatically moves the device; a rechargeable battery that supplies power, used for performing travel control, during the automatic travel; a charging stand searching part that searches the position of the charging stand; and a control part. When the control part determines that the electronic device needs to return to the charging stand, the control part executes return processing in which the electronic device is rotated in a static state after being put into the static state by the travel control part, and then, moved in a direction, where the charging stand is present, when the charging stand searching part searches the direction, where the charging stand is present, and detects the direction of the charging stand.
