Automatic Weekly Scheduling & Wall Climbing Without the Flagship Price
Floor & Wall Climbing
Continuous HyperGrip™ rubber tracks grip vinyl, fiberglass, and gunite walls instead of stopping at the floor like entry-level cleaners.
Weekly Smart Timer Included
Schedule automatic 2-hour cleanings every day right on the included power supply.
Top-Load MaxBin™ Basket
Pop the top lid, lift the oversized cartridge bin with one hand, and rinse leaves and dirt clean in seconds.
2×-Speed HyperBrush™
Active front brush spins twice as fast as the robot travels to scrub stuck-on algae and dirt loose.
CleverClean™ Pool Mapping
Scans pool dimensions and navigates around steps and drains systematically.
Featherlight ~14-Lb Handling
Fast water-release vents make lifting the Cayman out of the pool effortless for any family member.
The Smart Upgrade Over Entry-Level Floor-Only Robots
Step up from basic floor-only vacuums without paying $1,600+ for flagship extras. Weighing just ~14 lbs dry, the Dolphin Cayman pairs continuous HyperGrip™ rubber tracks and a 2×-speed HyperBrush™ to scrub both your pool floor and vertical walls on a crisp 2-hour cycle.
Built-In Weekly Timer & NanoFilter™ Expandability
Unlike base Nautilus models that require manual button presses before every run, the Cayman includes Maytronics' Programmable Weekly Smart Timer power supply right in the box—letting you automate cleanings all week for pennies per cycle. Its top-load MaxBin™ basket ships with standard mesh panels and accepts optional NanoFilter™ ultra-fine pleated panels whenever you want 2-micron silt polishing.

Does the Weekly Timer come in the box?
