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.

First claim

What is claimed is:

1. A power supply for a pool cleaner, comprising:
a housing;
a user interface;
a low-power user interface printed circuit board, the low-power user interface printed circuit board in electrical communication with the user interface; and
a potted power converter board assembly, comprising:
a tray;
a high-power printed circuit board including a plurality of electrical components and low-power user interface wires, the high-power printed circuit board positioned within the tray;
an AC power input connector in electrical communication with the high-power printed circuit board and providing a power input to the high-power printed circuit board;
a female power and communication output port in electrical communication with the high-power printed circuit board and providing power output from the high-power printed circuit board; and
a potting compound positioned within the tray and surrounding the high-power circuit board and the electrical components, the potting compound isolating the high-power circuit board and the electrical components, the low-power user interface wires extending out from the potting compound and in electrical communication with the low-power user interface printed circuit board;

wherein the low-power user interface wires provide power to the low-power user interface printed circuit board.

2. The power supply of claim 1 , wherein the housing includes a front housing and a rear housing, and the low-power user interface printed circuit board and the potted power converter board assembly are positioned between the front housing and the rear housing.

3. The power supply of claim 2 , wherein the low-power user interface printed circuit board is mounted to the front housing.

4. The power supply of claim 3 , wherein the potted power converter board assembly includes a plurality of stops extending between the tray and the front housing, the plurality of stops restricting flexion of the low-power user interface printed circuit board.

5. The power supply of claim 3 , wherein the potted power converter board assembly includes a plurality of mounting brackets and the rear housing includes a plurality of mounting bosses, the potted power converter board assembly being retained by the rear housing with the plurality of mounting brackets engaged with the plurality of mounting bosses of the rear housing.

6. The power supply of claim 1 , wherein the high-power printed circuit board includes a first side, a second side, and a heat sink, the plurality of electrical components mounted to the first side and the heat sink mounted to the second side.

7. The power supply of claim 6 , wherein the heat sink is a folded sheet metal heat sink.

8. The power supply of claim 1 , wherein the user interface is mounted to the housing and the connector extends through a connector opening in the housing to connect to the low-power user interface printed circuit board.

9. The power supply of claim 1 , wherein a graphic overlay including a plurality of semi-transparent indicia is positioned over the user interface.

10. The power supply of claim 1 , comprising low-power fan wires and a fan, wherein the low-power fan wires are connected to the high-power printed circuit board, extend out from the potting compound, and are connected to the fan to provide low-power to the fan, wherein the fan is positioned adjacent the potting compound and cools the potted power converter board assembly through forced convection.

11. The power supply of claim 10 , wherein the housing includes a fan opening and the fan is positioned within the fan opening.

12. The power supply of claim 11 , wherein the fan is secured in place by a fan cover that is removably connected to the housing and covers the fan opening.

13. The power supply of claim 1 , wherein the tray includes a port opening and the female power and communication output port includes a barrier that is positioned within the port opening and prevents potting compound from leaking out from the tray.

14. The power supply of claim 1 , wherein the user interface printed circuit board includes a plurality of light-emitting diodes and the housing includes a plurality of openings that allow the light-emitting diodes to be viewed from the exterior of the housing.

15. The power supply of claim 14 , comprising a light baffle that includes a plurality of apertures, the light baffle being positioned over the user interface printed circuit board with the light-emitting diodes positioned within the apertures, wherein the light baffle prevents cross-talk between the light-emitting diodes.

16. The power supply of claim 1 , comprising a recessed handle provided in the housing.

17. The power supply of claim 16 , comprising a plurality of vents on sides of the housing, the vents positioned to vent hot air away from the handle.

18. The power supply of claim 1 , wherein the electrical components of the high-power printed circuit board form a contoured landscape, and the tray includes a plurality of contours defining a plurality of interior recesses, the contours matching the contoured landscape formed by the electrical components of the high-power printed circuit board,
wherein when the high-power printed circuit board is positioned within the tray the electrical components are positioned within the interior recesses of the tray.

19. The power supply of claim 18 , wherein a substantially uniform space is formed between the plurality of electrical components and the plurality of contours of the contoured tray, the substantially uniform space being filled with potting compound.

20. The power supply of claim 19 , wherein the substantially uniform space provides substantially unified strain during thermal expansion of the potting compound.

21. The power supply of claim 1 , wherein the high-power printed circuit board limits the power provided to the low-power printed circuit board.

22. The power supply of claim 21 , wherein the high-power printed circuit board includes a positive temperature coefficient thermistor that limits the power provided to the low-power printed circuit board to less than or equal to 15 watts.

23. The power supply of claim 1 , comprising a control cable extending from a pool cleaner and connected to the female power and communication output port, the control cable providing power and control commands to the pool cleaner.

24. The power supply of claim 23 , wherein the high-power printed circuit board includes a thermistor that provides a measurement of the temperature of the high-power printed circuit board, and the pool cleaner adjusts its operation based on the temperature of the high-power printed circuit board.
