Abstract
A robotic cleaner including a dust cup door and door actuator. The door actuator is configured to move the dust cup door to an open position when the robotic cleaner is in a horizontal orientation to allow debris on a surface to be cleaned to be drawn into the dust cup, and to move the dust cup door to a closed position when the robotic cleaner is rotated from the horizontal orientation to a rotated orientation to substantially prevent debris in the dust cup from exiting the robotic cleaner.
Claims20
A robotic cleaner comprising:
- a chassis defining an air inlet;
- a dust cup defining a debris inlet and a cavity for receiving debris through the debris inlet;
- a suction motor configured to generate suction airflow in a suction airflow path extending between the air inlet and the debris inlet;
- a dust cup door disposed in the suction airflow path and movable between an open position and a closed position;
- and
- a door actuator coupled to the dust cup door,
- the door actuator configured to move the dust cup door to the open position when the robotic cleaner is in a horizontal orientation to allow debris on a surface to be cleaned to be drawn into the dust cup through the debris inlet by the suction airflow, and
- the door actuator configured to move the dust cup door to the closed position when the robotic cleaner is rotated from the horizontal orientation to a rotated orientation to substantially obstruct the suction airflow path to prevent debris in the dust cup from exiting the robotic cleaner through the air inlet.

A robotic cleaning system comprising:
- a robotic cleaner comprising
- a dust cup defining a debris inlet and a cavity for receiving debris through the debris inlet,
- a suction motor configured to generate suction airflow in a suction airflow path extending between the air inlet and the debris inlet,
- a dust cup door disposed in the suction airflow path and movable between an open position and a closed position, and
- a door actuator coupled to the dust cup door;
- and
- a docking station comprising a ramp for receiving the robotic cleaner,
- wherein the door actuator is configured to maintain the dust cup door in an open position during a cleaning operation of the robotic cleaner to allow debris on a surface to be cleaned to be drawn into the dust cup through the debris inlet by the suction airflow, and
- wherein the door actuator is configured to maintain the dust cup door in a closed position when the robotic cleaner is on the ramp to substantially obstruct the suction airflow path to prevent debris in the dust cup from exiting the robotic cleaner through the air inlet.
