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.
