Claim 23:
24. An evacuation station comprising:
a canister;
an intake configured to interface with an autonomous robotic cleaner;
one or more conduits extending from the intake into the canister; and
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 the canister,
wherein the canister comprises:
a bin;
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;
an interior wall, the interior wall being in direct contact with the filter wall and configured to cause at least a portion of the airflow to travel along a surface of the interior wall after the airflow travels through the filter wall such that at least a further portion of the first debris separates from the airflow and is collected within the bin of the canister, the surface of the interior wall defining an interior space; and
a plurality of conical separators comprising inlets positioned within the interior space defined by the surface of the interior wall, wherein the inlets of the plurality of conical separators are configured to receive the airflow after at least the portion of the airflow travels along the surface of the interior wall such that the plurality of conical separators separate at least a portion of the second debris from the airflow.
