1. A robotic cleaner comprising:
a chassis;
an agitator assembly configured to engage a surface to be cleaned; and
a lift moveably coupling the agitator assembly to the chassis, the lift including:
a spring configured to generate a biasing force that urges the agitator assembly in a direction away from the surface to be cleaned, the biasing force being insufficient to lift the agitator assembly from the surface to be cleaned;
a top plate;
a bottom plate; and
a plurality of linkages, a first end of each linkage being pivotally coupled to the top plate and a second end of each linkage being slidably coupled to the bottom plate.
