Abstract

A method and a set of pool cleaning robots for cleaning a pool. The set includes a first pool cleaning robot and a second pool cleaning robot that differ from each other by at least one unit out of a propulsion unit and a cleaning unit. Each one of the first pool cleaning robot and the second pool cleaning robot includes a filtering unit, a housing, and a controller.

Claims

1. A set of pool cleaning robots for cleaning a pool, wherein the set comprises a first pool cleaning robot and a second pool cleaning robot that differ from each other by at least one unit out of a propulsion unit and a cleaning unit;

wherein each one of the first pool cleaning robot and the second pool cleaning robot comprises a filtering unit, a housing, and a controller.

2. The set according to claim 1 wherein the first and second pool cleaning robots are configured to clean at least one region of the pool in a cooperative manner.

3. The set according to claim 1 wherein at least one pool cleaning robot of the set is configured to clean a sidewall of the pool.

4. The set according to claim 1, wherein at least one pool cleaning robot of the set is configured to perform collision avoidance steps for preventing a collision between the first pool cleaning robot and the second pool cleaning robot.

5. The set according to claim 1 wherein at least one of the set is configured to perform cable entanglement avoidance steps for preventing an entanglement of a cable connected to the first pool cleaning robot with a cable connected to the second pool cleaning robot.

6. The set according to claim 1 wherein a cleaning unit of the first pool cleaning robot comprises a PVC brush wheel and does not include a Polyvinyl acetate (PVA) sponge brush wheel;

and wherein a cleaning unit of the second pool cleaning robot comprises a PVA sponge brush wheel and does not include a PVC brush wheel.

7. The set according to claim 1 wherein only one of the first pool cleaning robot and the second pool cleaning robot comprises a sponge brush wheel.

8. The set according to claim 1 wherein only one of the first pool cleaning robot and the second pool cleaning robot comprises a brush wheel that comprises a sponge brush wheel portion and a PVC brush wheel portion.

9. The set according to claim 1 wherein the first pool cleaning robot is configured to remove coarser dirt than the second pool cleaning robot.

10. The set according to claim 1 wherein the first pool cleaning robot is configured to hover between a bottom of a pool floor and a waterline.

11. The set according to claim 1 wherein the first pool cleaning robot is configured to skim the water surface and then sink to the bottom floor.

12. The set according to claim 1, wherein the first pool cleaning robot and the second pool cleaning robot are configured to clean different regions of the pool.

13. The set according to claim 1, wherein the first pool cleaning robot comprises a detachable module, wherein the first pool cleaning robot and the second pool cleaning robot are configured to interchangeably receive the detachable module.

14. The set according to claim 1, wherein the first pool cleaning robot comprises a detachable sensor, wherein the first pool cleaning robot and the second pool cleaning robot are configured to interchangeably receive the detachable sensor.

15. The set according to claim 1 wherein the first pool cleaning robot and the second pool cleaning robot are configured to clean a same region of the pool at different manners.

18. The set according to claim 15, wherein the first pool cleaning robot is configured to perform a preliminary cleaning of the region and the second pool cleaning robot is configured to perform a supplementary cleaning of the region, wherein the preliminary cleaning is slower than the supplementary cleaning.

22. The set according to claim 1 wherein the first pool cleaning robot is configured to clean a slippery flat bottom region of the pool.

24. The set according to claim 1 wherein the first pool cleaning robot and the second pool cleaning robot cooperatively reallocate cleaning tasks according to failure to complete cleaning tasks.

25. The set according to claim 18 wherein failure to completing tasks are failure to traverse slippery pool surfaces.

26. The set according to claim 1 wherein only the first pool cleaning robot is configured to clean a slippery sloped bottom region of the pool.

27. The set according to claim 1 wherein only one of the first pool cleaning robot and the second pool cleaning robot comprises a jet propulsion unit.
