CLAIMS

1. A method of a robotic cleaning device (100) of controlling operation of a cleaning program in progress, comprising:

receiving (Sioi) an instruction to pause the cleaning program in progress;

travelling (S102), in response to said instruction to pause, to a charging station (300) to recharge a robotic cleaning device battery (117);

receiving (S103) a further instruction to resume the cleaning program that was in progress upon receiving the instruction to pause; and

resuming (S104), in response to said further instruction, the cleaning program that was in progress upon receiving the instruction to pause.

2. The method of claim 1, wherein the instruction to pause is received from the battery (117) indicating low power.

3. The method of claims 1 or 2, wherein the instruction to pause is received from a user.

4. The method of any one of claims 1-3, further comprising:

recording, in response to said instruction to pause, a current robotic cleaning device position; wherein the resuming (S104) of the cleaning program comprises:

travelling to the recorded robotic cleaning device position for resuming the cleaning program that was in progress upon receiving the instruction to pause.

5. The method of any one of claims 1-4, further comprising:

recording, in response to said instruction to pause, a next robotic cleaning device position as stipulated by the cleaning program; wherein the resuming of the cleaning program comprises:

travelling to the recorded next robotic cleaning device position for resuming the cleaning program that was in progress upon receiving the instruction to pause.

6. The method of any one of claims 1-5, said further instruction being configured to cause the robotic cleaning device (100) to immediately resume the paused cleaning program upon being received, or to resume the paused cleaning program after a set time period has elapsed as indicated by said further instruction.

7. Robotic cleaning device (100) configured to control operation of a cleaning program in progress, comprising:

a propulsion system (112, 113, 115a, 115b) configured to move the robotic cleaning device (100);

at least one battery (117) configured to power the robotic cleaning device

(100); and

a controller (116) configured to:

receive an instruction to pause the cleaning program in progress;

control, in response to said instruction to pause, the propulsion system (112, 113, 115a, 115b) to cause the robotic cleaning device (100) to travel to a charging station to recharge the robotic cleaning device battery (117);

receive a further instruction to resume the cleaning program that was in progress upon receiving the instruction to pause; and

resume, in response to said further instruction, the cleaning program that was in progress upon receiving the instruction to pause.

8. The robotic cleaning device (100) of claim 7, wherein the instruction to pause is received from the battery (117) indicating low power.

9. The method of claims 1 or 2, wherein the instruction to pause is received from a user via a robotic cleaning device user interface.

10. The robotic cleaning device (100) of any one of claims 7-9, the controller (116) further being configured to:

record, in response to said instruction to pause, a current robotic cleaning device position; and further being configured to, upon resuming the cleaning program:

control the propulsion system (112, 113, 115a, 115b) to cause the robotic cleaning device (100) to travel to the recorded robotic cleaning device position for resuming the cleaning program that was in progress upon receiving the instruction to pause.

11. The robotic cleaning device (100) of any one of claims 7-10, the controller (116) further being configured to:

record, in response to said instruction to pause, a next robotic cleaning device position as stipulated by the cleaning program; and further being configured to, upon resuming the cleaning program:

control the propulsion system (112, 113, 115a, 115b) to cause the robotic cleaning device (100) to travel to the recorded next robotic cleaning device position for resuming the cleaning program that was in progress upon receiving the instruction to pause.

12. The robotic cleaning device (100) of any one of claims 7-11, said further instruction being configured to cause the robotic cleaning device (100) to immediately resume the paused cleaning program upon being received, or to resume the paused cleaning program after a set time period has elapsed as indicated by said further instruction.

13. A computer program (125) comprising computer-executable

instructions for causing a robotic cleaning device (100) to perform the steps recited in any one of claims 1-6 when the computer-executable instructions are executed on a controller (116) included in the robotic cleaning device (100).

14. A computer program product comprising a computer readable medium (126), the computer readable medium having the computer program (125) according to claim 13 embodied thereon.
