Dolphin builds very different robots under one badge. The Cayman handles smaller inground pools and walls; the Premier, Sigma and Quantum step up to 50 ft-class pools with waterline cleaning, longer cables and finer filtration. This category limits the comparison to Dolphin models suited to residential inground pools, so coverage, NanoFilters, MaxBin capacity, scheduling and warranty can be compared without unrelated above-ground or commercial machines.

For pools up to about 33 ft, the Cayman is the light, floor-and-wall choice. For a standard 40–50 ft inground pool, the ProLine models add a 60 ft-class cable and waterline cleaning. Premier prioritizes mixed debris and leaves, Sigma prioritizes navigation and app control, and Quantum balances fine filtration with a large top-load bin.
Surface does not require a different Dolphin model: vinyl, fiberglass, plaster, pebble and tile are all compatible when the brushes are clean and in good condition. Choose by pool length, the areas you want cleaned and the debris the filter must hold.
Light floor-and-wall cleaning with MaxBin capacity and a weekly timer for smaller pools.
Multi-Media filtration and an oversized leaf bag for changing or heavy debris.
Gyroscope navigation, app control and strong active scrubbing.
Waterline cleaning with NanoFilters inside an XXL MaxBin.
Start with the Premier, Sigma or Quantum. They are the residential Dolphin models in this group built around long cables and floor, wall and waterline coverage.
No. The Cayman cleans floors and walls. The Premier, Sigma and Quantum add waterline coverage.
Yes. Dolphin robots use pool-safe tracks and brushes on vinyl, fiberglass, plaster, pebble and tile. Rinse abrasive grit from the brushes after use.
