Abstract

A pool cleaning robot for cleaning a pool that may include a filtering unit; a housing; an impeller; a pump motor for rotating the impeller; a drive system; and an interface for coupling an extraction element to the pool cleaning robot, during a pool exit process; and wherein during at least a part of the pool exit process an upper end of the interface is higher than the housing.

First claim

We claim:

1. A pool cleaning robot for cleaning a pool, comprising: a filtering unit for filtering fluid; a housing that surrounds the filtering unit; an impeller configured to induce fluid to pass through the filtering unit when rotated at a first direction; a pump motor for rotating the impeller; a drive system; first interfacing elements that are configured to interface with the pool during a cleaning process of the pool; and second interfacing elements that extend outside a bottom of the housing, are positioned at a central area of the bottom of the housing and between the first interfacing elements; and wherein during a part of a pool exit process the second interfacing elements contact an edge of the pool.

2. The pool cleaning robot according to claim 1 wherein the pool cleaning robot further comprises an interface for coupling an extraction element to the pool cleaning robot, during a pool exit process; and wherein during at least a part of the pool exit process an upper end of the interface is higher than the housing.

3. The pool cleaning robot according to claim 2 wherein the interface comprises a coupling element that is coupled to the extraction element.

4. The pool cleaning robot according to claim 1 wherein the second interfacing elements are tubes, rods or wheels.

5. The pool cleaning robot according to claim 1 wherein the interface consists essentially of a spring.

6. The pool cleaning robot according to claim 1 wherein the interface consists essentially of a shape memory spring.

7. The pool cleaning robot according to claim 1 wherein the interface is a shape-memory elastic anchor.

8. The pool cleaning robot according to claim 1 wherein the interface is an elastic telescopic bar.

9. The pool cleaning robot according to claim 1 wherein a lower end of the interface is connected to the housing.

10. The pool cleaning robot according to claim 1 wherein during at least a part of the pool exit process at least a majority of the interface is higher than the housing.

11. The pool cleaning robot according to claim 1 wherein the extraction element is a cable.

12. The pool cleaning robot according to claim 11 wherein the cable is threaded through the interface.

13. The pool cleaning robot according to claim 1 comprising a sensor for measuring an amount of water within the pool cleaning robot.

14. The pool cleaning robot according to claim 1 wherein the second interfacing elements are rotatable tubes, rotatable rods or rotatable wheels.

15. The pool cleaning robot according to claim 1 wherein the second interfacing elements are static.

16. The pool cleaning robot according to claim 1 wherein adjacent second interfacing elements contact each other.

17. The pool cleaning robot according to claim 1 wherein a distance between adjacent second interfacing elements is a fraction of a radius of each one of the adjacent second interfacing elements.

18. A pool cleaning robot for cleaning a pool, comprising: a filtering unit for filtering fluid; a housing that surrounds the filtering unit; an impeller configured to induce fluid to pass through the filtering unit when rotated at a first direction; a pump motor for rotating the impeller; a drive system; and an interface for coupling an extraction element to the pool cleaning robot, during a pool exit process; and wherein during at least a part of the pool exit process an upper end of the interface is higher than the housing; wherein one of the following is true: (a) the interface comprises a spring and a coupling element that is coupled to the extraction element, (b) the interface consists essentially of a spring, (c) the interface consists essentially of a shape memory spring, and (d) the interface is a shape-memory elastic anchor.
