Abstract

Some embodiments include a debris bag for a pool cleaner. The debris bag includes a sheet of filtration media that forms an opening and a hollow interior portion to capture debris from the pool cleaner. An attachment fixture is located at the opening and includes a ring having a hook area for coupling the attachment fixture to an outlet of the pool cleaner.

First claim

The invention claimed is:

1. A debris bag for a pool cleaner, the debris bag comprising:
a sheet of filtration media that forms an opening;
a hollow interior portion to capture debris from the pool cleaner; and
an attachment fixture at the opening, the attachment fixture including a ring having a hook area for coupling the attachment fixture to an outlet of the pool cleaner, the ring including a first outer ring half and a second outer ring half hinged together and secured around an inner ring.

2. The debris bag of claim 1 , wherein the hook area is disposed adjacent a bottom edge of the attachment fixture.

3. The debris bag of claim 1 , wherein the hook area is defined by two hook areas disposed on opposing sides of the attachment fixture.

4. The debris bag of claim 3 , wherein the hook areas each include a slot for interacting with the pool cleaner.

5. The debris bag of claim 1 further including a pin hole.

6. The debris bag of claim 5 , wherein the ring includes a pin.

7. The debris bag of claim 6 , wherein the debris bag is at least partially secured to the ring when the pin is inserted into the pin hole.

8. The debris bag of claim 1 further including a support fixture disposed within the debris bag to support the debris bag in an upright position when the attachment fixture is coupled to the pool cleaner.

9. The debris bag of claim 1 , wherein the debris bag only includes a single opening.

10. A disposable debris bag for a pool cleaner, the debris bag comprising:
a sheet of filtration media that forms a single opening, the filtration media having a permeability between about 900 cfm/ft 2 and about 1,200 cfm/ft 2 ;
a hollow interior portion to capture debris from the pool cleaner; and
an attachment fixture associated with the opening, the attachment fixture having a hook area for coupling the attachment fixture to an outlet of the pool cleaner.

11. The debris bag of claim 10 , wherein the filtration media is one of non-woven polylactic acid fabric or non-woven polyhydroxy butyrate.

12. The debris bag of claim 10 , wherein the filtration media has a thickness of between about 0.0006 inches and about 0.012 inches.

13. The debris bag of claim 10 , wherein the attachment fixture includes an inner ring and an outer ring.

14. The debris bag of claim 13 , wherein the outer ring is wrapped around the inner ring to secure the debris bag to the attachment fixture.

15. The debris bag of claim 14 , wherein the outer ring is defined by a first outer ring half and a second outer ring half that are hinged together.

16. A pressure-side pool cleaner assembly, the pool cleaner assembly comprising:
a pool cleaner body having a circular outlet extending from an upper portion of the body;
a plurality of wheels associated with the pool cleaner; and
a debris bag coupled to the outlet, the debris bag including
a sheet of filtration media that forms an opening;
a hollow interior portion to capture debris from the pool cleaner; and

an attachment fixture circumscribing the opening, the attachment fixture including an inner ring that receives the opening and an outer ring that surrounds the inner ring, the outer ring defined by a first outer ring half and a second outer ring half that are hinged together.

17. The pool cleaner assembly of claim 16 , wherein the outer ring snaps together to couple the debris bag to the attachment fixture.

18. The pool cleaner assembly of claim 16 , wherein the filtration media has a permeability between about 900 cfm/ft 2 and about 1,200 cfm/ft 2 .

19. The pool cleaner assembly of claim 16 , wherein the debris bag extends substantially upright from the outlet.

20. The pool cleaner assembly of claim 16 , wherein the attachment fixture includes two hook areas for coupling the attachment fixture to the outlet of the pool cleaner.
