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 apparatus 1 includes: a dust transfer pipe 22 that is connected to an autonomous robotic vacuum cleaner 2, and that sucks in dust collected by the cleaner 2; a suction passage 61 that sucks in other dust that is different to dust collected by the cleaner 2; a secondary dust container 28 that is connected to the pipe 22 and the suction passage 61; an electric blower 29 that applies a negative pressure to the pipe 22 and the suction passage 61; and a switching valve unit 72 that is capable of switching a channel that is connected to the dust container 28 so as to allow either one of, and block the other of, flowing between the pipe 22 and the dust container 28 and flowing between the suction passage …
