Pros
- Handles fine debris well
- Works for both pools
- Faster cleaning cycles
Cons
- Limited coverage length
- Thin maintenance details
This Dolphin Cayman stands out for in-ground and above-ground setups because it handles fine debris well and keeps cleaning on a fast 2 hr cycle. In real pools, that matters more than chasing spotless floors. It also works across both pool types, so you are not switching to a different robot when you change houses or pool styles.
The main trade-off is coverage length. It is rated for up to 33 ft, and the “Limited coverage length” note is the kind that shows up in longer pools. It is a solid fit for most average-sized in-ground and above-ground pools, especially if you want strong dust and sand pickup with fewer reruns. Maintenance details are also a bit light, so plan on spending some time figuring out the easiest rinse and filter routine for your pool.
