Self-cleaning dust collection seats and a system. A self-cleaning dust collection seat comprises a self-cleaning dust collection seat body (2000), and a body base (6000) is arranged below the self-cleaning dust collection seat body (2000). The body base (6000) comprises: a dust collection port (6100) configured to collect dust after being docked with a dust outlet of an automated cleaning apparatus, the dust collection port (6100) extending in a first direction; and a base air duct (2520) communicating with the dust collection port (6100) and extending in a first direction to a position substantially at an edge of the body base (6000), and then extending in a second direction, the second direction being substantially perpendicular to the first direction. The self-cleaning dust collection seat body (2000) comprises: a dust collection cavity (2100) arranged, with the opening facing upward and forward, on the top end of the self-cleaning dust collection seat body (2000); and a body air duct (2510) communicating with the base air duct (2520) and at least provided on a side wall of the self-cleaning dust collection seat body (2000), and the base air duct (2520) communicates with the dust collection cavity (2100) through the body air duct (2510). By means of optimizing the air duct structure inside the self-cleaning dust collection seat (2000), the air duct ensures smoother flow, the structure is more compact, and further the dust collection efficiency of an automated cleaning apparatus is improved.
