Electric vacuum cleaner apparatus

An electric vacuum cleaner apparatus includes: a station, an electric vacuum cleaner attachable to the station, and plural attaching detectors which can detect the electric vacuum cleaner is attached in the station. The electric vacuum cleaner includes a cleaner body; a tubular part connected to the cleaner body and sucks in dust; and a primary dust container that stores dust sucked in with the tubular part. The station includes a secondary dust container that stores dust discharged from the primary dust container. The electric vacuum cleaner apparatus permits transfer of dust from the primary dust container to the secondary dust container when at least two of the plural attaching detectors have detected the attaching of the electric vacuum cleaner to the station. The electric vacuum cleaner apparatus can reliably confirm the vacuum cleaner is placed at a correct position on the charging station so that dust to be discarded from the primary dust container to the secondary dust container does not leak around the electric vacuum cleaner apparatus.
