Abstract: A robotic cleaner may include a chassis, an agitator assembly configured to engage a surface to be cleaned, and a lift mechanism moveably coupling the agitator assembly to the chassis. The lift mechanism may include a biasing mechanism. The biasing mechanism may be configured to generate a biasing force that urges the agitator assembly in a direction away from the surface to be cleaned. The biasing force may be insufficient to lift the agitator assembly from the surface to be cleaned.

Abstract: A robotic cleaner may include a housing, an agitator, and one or more projections. The housing may have a front side, a back side opposite the front side, a left side, and a right side opposite the left side. The right and left sides extend between the front and back sides. The agitator may be configured to rotate about an agitator rotation axis, the agitator rotation axis extending substantially parallel to the front side. The one or more projections may extend from the housing. The one or more projections may include one or more cliff sensors.

Abstract: A robotic cleaning system may include a robotic cleaner having a robotic cleaner dust cup and a docking station having a docking station dust cup configured to fluidly couple to the robotic cleaner dust cup. The docking station dust cup may include a first debris collection chamber, a second debris collection chamber fluidly coupled to the first debris collection chamber, and a filter fluidly coupled to the first debris collection chamber and the second debris collection chamber.
