摘要: A robot cleaner includes a rolling cleaning module including a rolling member configured to rotate clockwise or counterclockwise when viewed from a left side while in contact with a floor, a sensor unit, and a controller. The controller is configured to determine a change in position of the robot cleaner and a change in load current of a motor connected to the rolling member based on data detected by the sensor unit, and determine that a specific area of the floor is a contaminated area when there is a change in the position and a change in the load current.

摘要: An autonomous coverage robot includes a chassis having forward and rearward portions and a drive system carried by the chassis. The forward portion of the chassis defines a substantially rectangular shape. The robot includes a cleaning assembly mounted on the forward portion of the chassis and a bin disposed adjacent the cleaning assembly and configured to receive debris agitated by the cleaning assembly. A bin cover is pivotally attached to a lower portion of the chassis and configured to rotate between a first, closed position providing closure of an opening defined by the bin and a second, open position providing access to the bin opening. The robot includes a body attached to the chassis and a handle disposed on an upper portion of the body. A bin cover release is actuatable from substantially near the handle.
