Perfect fit
These were a perfect replacement for worn and broken pulley on our Dolphin Nautilus CC Plus and installation was very easy. For less than $25, I expect to get a lot more life out of my pool bot.

Fixed my pool cleaner right up. Parts are well made and fit my model of the pool cleaner.

Fit my Kreepy 820 Prowler perfectly
Repaired my Kreepy exactly as advertised! Be careful taking the KK apart, the plastic tabs will cracked if not careful. Maybe use the plastic trim tools to take apart.

Exact part replacement
Rebuilt my Mayback pool leaner. Everything matched up to the gears and belts. Easy rebuild

Test within your return window
1 of the guide wheels does not snap in like the others so the belt keeps coming off because the guide wheel slips off.

Just worth it!!
My nautillus pool cleaner was stopping after running for about 30s from start. After replacing the gears and guide wheels. The pool vaccum robot just works.

Great fit and easy repair
Was easy to replace the original ones after watching a couple of videos on you tube.

Parts for Dolphin Supreme M4
Fitted good and working as intended. However, about half the steel balls from the guide wheels have come off just after 2-3 cycles, which is disappointing.
