Abstract

Exemplary embodiments are directed to pool cleaners that remove debris from water using a plurality of cyclonic flows, or that include a removable impeller subassembly, a check valve for a debris canister, a particle separator assembly having a handle that locks to the pool cleaner, a modular roller drive gear box, or a roller latch that secures a roller to the pool cleaner. Exemplary embodiments are also directed to the check valve and the roller latch themselves. Exemplary embodiments are directed to a filter medium for pool cleaners that includes embossments providing flow channels for water, and to roller assemblies for pool cleaners. Exemplary embodiments are directed to pool cleaners including alternative pump motor engagements. Exemplary embodiments are directed to pool cleaners power supplies that include a potted and contoured power board assembly, and to kickstands therefor. Exemplary embodiments are directed to a pool cleaner caddy, and removable wheels therefor.

Claims

1. A pool cleaner for cleaning a pool or spa, comprising:

a chassis having a motor box housing, a first drive gear box housing, and a second drive gear box housing;

a first roller set;

a second roller set;

a first roller drive gear train in mechanical communication with the first roller set;

a second roller drive gear train in mechanical communication with the second roller set;

a first roller drive gear box including a housing and a first gear stack secured within the housing, the first roller drive gear box removably mounted within the first drive gear box housing and in mechanical communication with the first roller drive gear train;

a second roller drive gear box including a housing and a second gear stack secured within the housing, the second roller drive gear box removably mounted within the second drive gear box housing and in mechanical communication with the second roller drive gear train; and

a motor box including a first drive motor and a second drive motor, the motor box mounted within the motor box housing with the first drive motor in mechanical communication with the first gear stack and the second drive motor in mechanical communication with the second gear stack;

wherein the first drive motor drives rotation of the first gear stack, the first gear stack drives rotation of the first roller drive gear train, and the first roller drive gear train drives rotation of the first roller set,

wherein the second drive motor drives rotation of the second gear stack, the second gear stack drives rotation of the second roller drive gear train, and the second roller drive gear train drives rotation of the second roller set, and

wherein said pool cleaner creates a suction effect at an inlet opening receiving debris-laden water from the pool or spa.

2. The pool cleaner of claim 1, wherein the first and second drive gear box housings include side walls, and the first and second roller drive gear boxes include sidewalls configured to match the sidewalls of the first and second drive gear box housings and align the first and second roller drive gear boxes when positioned within the first and second drive gear box housings.

3. The pool cleaner of claim 1, wherein the first and second drive gear box housings include a plurality of mounts, and the first and second roller drive gear boxes include a plurality of mounting tabs configured to align with the mounts to position the first and second roller drive gear boxes within the first and second drive gear box housings.

4. The pool cleaner of claim 1, wherein the first and second roller drive gear boxes include a removable lid secured to the housing, and the first and gear stacks are accessible when the lid is removed from the housing.

5. The pool cleaner of claim 1, wherein a gear of the first gear stack extends out from an opening in the housing and drives rotation of a first drive gear of the first roller drive gear train, and a gear of the second gear stack extends out from an opening in the housing and drives rotation of a second drive gear of the second roller drive gear train.

6. The pool cleaner of claim 5, wherein a first axle is engaged and rotates with the first drive gear and the gear of the first gear stack is engaged with and drives rotation of the first axle, and a second axle is engaged and rotates with the second drive gear and the gear of the second gear stack is engaged with and drives rotation of the second axle.

7. The pool cleaner of claim 1, wherein the first roller set includes a first front roller, a first middle roller, and a first rear roller.

8. The pool cleaner of claim 7, wherein the first drive motor drives the first front roller, the first middle roller, and the first rear roller at the same rate.

9. The pool cleaner of claim 1, wherein the second roller set includes a second front roller, a second middle roller, and a second rear roller.

10. The pool cleaner of claim 9, wherein the second drive motor drives the second front roller, the second middle roller, and the second rear roller at the same rate.

11. The pool cleaner of claim 1, wherein the first roller set includes a first front roller, a first middle roller, and a first rear roller;

the second roller set includes a second front roller, a second middle roller, and a second rear roller; and

the first and second front rollers are disposed adjacent to each other, the first and second middle rollers are disposed adjacent to each other, and the first and second rear rollers are disposed adjacent to each other.

12. The pool cleaner of claim 11, wherein the first drive motor drives the first front roller, the first middle roller, and the first rear roller at a first rate, and the second drive motor drives the second front roller, the second middle roller, and the second rear roller at a second rate that is different than the first rate to cause the pool cleaner to turn.

13. The pool cleaner of claim 11, wherein the first drive motor drives the first front roller, the first middle roller, and the first rear roller in a first rotational direction, and the second drive motor drives the second front roller, the second middle roller, and the second rear roller in a second rotational direction that is different than the first rotational direction to cause the pool cleaner to turn.

14. The pool cleaner of claim 1, wherein said pool cleaner includes a bottom configured to be positioned adjacent a bottom wall of the pool or spa when said pool cleaner is driven along the bottom wall, the bottom including the inlet opening.

15. The pool cleaner of claim 1, wherein said pool cleaner includes filtration means for separating debris from the debris-laden water and further includes an outlet for expelling the water from said pool cleaner.

16. The pool cleaner of claim 15, wherein said filtration means is a cyclone chamber.

17. The pool cleaner of claim 15, wherein said filtration means is a filter medium.

18. The pool cleaner of claim 15, wherein said filtration means is a cyclone container.

19. The pool cleaner of claim 1, wherein said pool cleaner is powered by an electric source.

20. The pool cleaner of claim 1, wherein said pool cleaner is a pressure cleaner or a suction cleaner.
