Claim 13:
14. An evacuation station comprising:
a canister;
an intake configured to interface with an autonomous robotic cleaner docked to the evacuation station;
one or more conduits extending from the intake into the canister;
an air mover to produce an airflow carrying first debris and second debris from the autonomous robotic cleaner, through the intake, through the one or more conduits, and into an interior of the canister, wherein the canister comprises a bin to collect at least some of the first debris and the second debris;
a filter wall having an annular cross section, wherein the filter wall is configured to separate at least a portion of the first debris from the airflow as the airflow travels through the filter wall,
a collision wall for separating at least a further portion of the first debris from the airflow, the collision wall being in direct contact with the filter wall and defining an interior space configured to receive the airflow after the airflow travels through the filter wall; and
a conical separator within the canister, the conical separator comprising an inlet configured to receive at least a portion of the airflow after the airflow is received by the interior space such that the conical separator separates at least a portion of the second debris from the airflow, wherein the inlet of the conical separator is positioned within the interior space defined by the collision wall.
