Abstract

The cleaning appliance group disclosed herein includes: a vacuum cleaner having a dust storage section with a dust storage space for storing dust sucked up during cleaning operations; a recovery device having a recovery pipe and a suction source, the recovery pipe being configured to connect to the dust storage section and having a flow channel allowing dust to flow out of the dust storage section, the suction source generating suction force for sucking dust out of the dust storage section through the recovery pipe; and a suction limiting section that increases the vacuum level in the recovery pipe by limiting the suction force of the suction source acting on the dust storage space of the dust storage section connected to the recovery pipe, and allows the suction force of the suction source to act on the dust storage space of the dust storage section when specified conditions are met. This eliminates the state of dust being stuck in the dust storage section and reduces the amount of dust continuously remaining in the dust storage section.
