Abstract

An autonomous cleaning robot includes a drive operable to move the autonomous cleaning robot across a floor surface; a cleaning assembly configured to clean the floor surface; a receiver configured to receive an indication of cat activity in a cat box; and a controller configured to navigate the autonomous cleaning robot to the cat box to execute a cleaning mission in response to the received indication of cat activity.

Claims (36)

1. A system for performing a cleaning mission, the system comprising:

one or more autonomous cleaning robots, each of the one or more autonomous cleaning robots comprising:

a drive operable to move the autonomous cleaning robot across a floor surface;

a cleaning assembly configured to clean the floor surface;

a receiver configured to receive an indication of pet activity in a pet area, wherein the indication of pet activity in the pet area comprises an indication that the pet has entered or exited the pet area, the indication of pet activity in the pet area having been generated by a motion sensor that is sensitive to the direction of motion of the pet; and

a controller configured to control each of the one or more autonomous cleaning robots to navigate to the pet area to execute a cleaning mission in response to the received indication of pet activity.

2. The method of claim 1 , wherein the cleaning mission comprises a dry cleaning stage and a wet cleaning stage.

3. The system of claim 2 , wherein the controller is configured to control the one or more autonomous cleaning robots to execute the wet cleaning stage of the cleaning mission subsequently to execution of the dry cleaning stage of the cleaning mission.

4. The system of claim 2 , wherein the one or more autonomous cleaning robots comprise a single autonomous cleaning robot configured to execute both the dry cleaning stage of the cleaning mission and the wet cleaning stage of the cleaning mission.

5. The system of claim 2 , wherein the one or more autonomous cleaning robots comprise:

a first robot of the one or more autonomous cleaning robot configured to execute the dry cleaning stage of the cleaning mission, and

a second robot of the one or more autonomous cleaning robot configured to execute the wet cleaning stage of the cleaning mission.

6. The system of claim 2 , wherein the dry cleaning stage of the cleaning mission comprises (1) a first stage in which the pet area is cleaned with a side brush of the one or more autonomous cleaning robots being inactive, and (2) a second stage following the first stage, in which in the second stage, the pet area is cleaned with the side brush being active.

7. The system of claim 2 , wherein execution of the dry cleaning stage of the cleaning mission comprises vacuuming or dry mopping the floor surface.

8. The system of claim 2 , wherein execution of the wet cleaning stage of the cleaning mission comprises wet mopping the floor surface.

9. The system of claim 1 , comprising the motion sensor.

10. A method for performing a cleaning mission comprising:

receiving at a receiver of one or more autonomous cleaning robots, an indication of pet activity in a pet area, wherein the indication of pet activity in the pet area comprises an indication that the pet has entered or exited the pet area, the indication of pet activity in the area having been generated by a motion sensor that is sensitive to the direction of motion of the pet, wherein each of the autonomous cleaning robots comprises:

a drive operable to move the autonomous cleaning robot across a floor surface,

a cleaning assembly configured to clean the floor surface, and

responsive to receiving the indication of pet activity in the pet area, controlling, by a controller, each of the one or more autonomous cleaning robots to navigate to the pet area; and

executing the cleaning mission.

11. The method of claim 10 , wherein executing the cleaning mission comprises:

executing a dry cleaning stage of the cleaning mission; and

executing a wet cleaning stage of the cleaning mission.

12. The method of claim 11 , comprising executing the wet cleaning stage of the cleaning mission subsequently to executing the dry cleaning stage of the cleaning mission.

13. The method of claim 11 , comprising executing the dry cleaning stage of the cleaning mission and executing the wet cleaning stage of the cleaning mission by a single autonomous cleaning robot.

14. The method of claim 11 , comprising:

executing the dry cleaning stage of the cleaning mission by a first robot of the one or more autonomous cleaning robots, and

executing the wet cleaning stage of the cleaning mission by a second robot of the one or more autonomous cleaning robots.

15. The method of claim 11 , wherein executing the dry cleaning stage of the cleaning mission comprises

(1) executing a first stage in which the pet area is cleaned with a side brush of the one or more autonomous cleaning robots being inactive, and

(2) executing a second stage following the first stage, in which in the second stage, the pet area is cleaned with the side brush being active.

16. The method of claim 11 , wherein executing the dry cleaning stage of the cleaning mission comprises vacuuming or dry mopping the floor surface.

17. The method of claim 11 , wherein executing the wet cleaning stage of the cleaning mission comprises wet mopping the floor surface.

18. The method of claim 10 , comprising receiving the indication that the pet has entered or exited the pet area from the motion sensor.
