What owners and long-term reviewers report, from public threads and published reviews; not our own testing.
- A hands-on tester found the CC Supreme cleaned the pool floor, climbed the walls without losing grip, and scrubbed the waterline where body-oil scum builds up.thepoolnerd.com
- The same tester said the robot's CleverClean navigation moved with purpose and covered the pool without leaving obvious gaps, rather than bumping around randomly.thepoolnerd.com
- The Pool Nerd's reviewer points out the CC Supreme uses standard cartridge filters, not the finer NanoFilters found on Dolphin's pricier ProLine models.thepoolnerd.com
- That same reviewer calls the one-year warranty the single biggest strike against the CC Supreme given its price.thepoolnerd.com
- The reviewer also warns that the warranty only holds up if the robot was bought from an Authorized Maytronics Dealer, which matters if you're shopping third-party listings.thepoolnerd.com
What independent testers found
We do not test units ourselves. These are figures and verdicts published by named testers, with the maker’s claim beside them where the tester gave it; where a tester relays owners’ reports rather than a measurement, the row says so.
| What | Finding | Tester |
|---|---|---|
| Wall climbing | Climbed the pool walls without losing grip during hands-on testing | The Pool Nerd |
| Also noted | Navigation covered the test pool with purpose and left no obvious gaps, rather than moving randomly | The Pool Nerd |
| Filter capacity | Ships with standard cartridge filters rather than the finer NanoFilters used on Dolphin's ProLine models | The Pool Nerd |
| Wall climbing | Climbed walls well and spent significant time scrubbing the waterline during testing | PoolBots |
| Also noted | Weighs about 24 lbs dry, with a 50-foot cable that has an anti-tangle swivel | PoolBots |
| Runtime | Standard cleaning cycle runs 2.5 hours (quick clean 1.5 hr / enhanced clean 3.5 hr options also offered) | PoolBots |
| Filter capacity | Only two filter media options (fine and ultra-fine), versus four on the cheaper Dolphin Premier | PoolBots |
| Debris pickup | Picked up silt and sand well but struggled with larger debris like leaves and pine needles | PoolBots |
- The Pool Nerd rates the CC Supreme as a good cleaner held back by its one-year warranty and standard filters, concluding it is not the smart buy at its price against Dolphin's own longer-warrantied lines. (Pool Nerd Disapproved) The Pool Nerd
- The reviewer's bottom line is that the CC Supreme cleans as well as Dolphin's other robots, but loses on value rather than performance. The Pool Nerd
- PoolBots concludes it's hard to see how the Nautilus CC Supreme's roughly $1,500 price aligns with its performance, given its app connectivity issues and limited filter options. PoolBots

- The best robotic pool cleaner for an inground pool (Longer pool rating and the waterline scrubbed too)
