1. An evacuation station for an autonomous cleaning robot, the evacuation station comprising:
a receptacle;
an intake configured to pneumatically connect with a debris bin of the autonomous cleaning robot;
an air mover to generate a negative pressure to produce an airflow to draw debris from the debris bin through the intake and into the receptacle during an evacuation process;
a sensor to receive data indicative of a parameter associated with a portion of a pathway for the airflow within the evacuation station as the air mover produces the airflow during the evacuation process; and
one or more processors configured to:
determine, based on the received data indicative of the parameter, a condition associated with the portion of the pathway, the condition comprising at least one of a clog, an obstruction, or an improper sealed engagement; and
cause a user notification indicative of the determined condition to be provided in response to detection of the condition.
