AUTONOMOUS FLOOR CLEANING WITH A REMOVABLE PAD
First Claim
1. An autonomous floor cleaning robot, comprising:
- a robot body defining a forward drive direction;
a controller supported by the robot body;
a drive supporting the robot body and configured to maneuver the robot across a surface in response to commands from the controller;
a pad holder disposed on an underside of the robot body and configured to retain a removable cleaning pad during operation of the cleaning robot; and
a pad sensor arranged to sense a feature of a cleaning pad held by the pad holder and generate a corresponding signal;
wherein the controller is responsive to the signal generated by the pad sensor, and configured to control the robot according to a cleaning mode selected from a set of multiple robot cleaning modes as a function of the signal generated by the pad sensor.

20. A method of cleaning a floor, the method comprising:
-
attaching a cleaning pad to an underside surface of an autonomous floor cleaning robot; placing the robot on a floor to be cleaned; initiating a floor cleaning operation in which the robot senses the attached cleaning pad and identifies a type of the pad from among a set of multiple pad types, and then autonomously cleans the floor in a cleaning mode selected according to the identified pad type.
