Self-propelled cleaner rechargeable traveling system and rechargeable traveling system

摘要

Disclosed is a rechargeable traveling system which enables a self-propelled machine to be charged properly without fail. Since a charging terminal, located on the back of the body of a self-propelled cleaner, is horizontally wider than a feeding terminal of a battery charger, even if the cleaner comes close to the feeding terminal somewhat horizontally out of alignment with the center of the battery charger, the charging terminal and the feeding terminal are connected properly without fail and thus charging is carried out properly without fail.
