Abstract: Provided is a self-traveling electronic apparatus including a housing whose lower part is uniquely shaped so that the self-traveling electronic apparatus can climb over level differences smoothly. The self-traveling electronic apparatus includes a housing, a drive wheel disposed at a bottom of the housing and coming in contact with a floor surface so that the housing travels on the floor surface, a follower wheel disposed on the bottom of the housing and coming in contact with the floor surface to support the housing, and a sloped plate disposed so as to lay smoothly from a front lower end of the housing to the bottom in a travel direction, wherein the housing has a bumper slidable in the travel direction; and a front end of the sloped plate is positioned behind a front lower end of the bumper in case the bumper slides backward.

Abstract: Disclosed is a suction and collection device that sucks in and collects matter to be collected that is on top of a collection surface, by a suction means that has a suction inlet with an opening formed in the front section of a body housing. In said suction and collection device, the body housing is provided with a blowing means that has an outlet positioned lower than the suction inlet and that blows an air current along the collection surface from the outlet towards the front. The speed of the air current sucked into the suction inlet is made greater than the speed of the air current blown out of the outlet and the air current that is blown out of the outlet is sucked into the suction inlet.
