Abstract
An electric vacuum cleaning apparatus that offers a high degree of convenience is provided that is capable of easily switching between a function that empties dust from an electric vacuum cleaner by moving dust collected by the cleaner to a station and accumulating the dust at the station, and a function that accumulates dust that is swept up together after quickly performing localized cleaning using an cleaning implement other than the cleaner at the station. An electric vacuum cleaning apparatusincludes: a dust transfer pipethat is connected to an autonomous robotic vacuum cleaner, and that sucks in dust collected by the cleaner; a suction passagethat sucks in other dust that is different to dust collected by the cleaner; a secondary dust containerthat is connected to the pipeand the suction passage; an electric blowerthat applies a negative pressure to the pipeand the suction passage; and a switching valve unitthat is capable of switching a channel that is connected to the dust containerso as to allow either one of, and block the other of, flowing between the pipeand the dust containerand flowing between the suction passageand the dust container
