Maytronics Dolphin Nautilus Titan

Name: Maytronics Dolphin Nautilus Titan
Brand: Maytronics

Maytronics' large-pool Nautilus model, rated for in-ground pools up to 50 ft with waterline scrubbing and app scheduling. Every performance claim here comes from Maytronics; no independent hands-on test was found.

Autonomy Ladder

Why Level II.

One five-rung scale, every category, from acting only on command to working unsupervised anywhere.

VGeneralized AutonomyAny task, any setting. No consumer robot has reached it.
IVEnvironmental AutonomyCopes with everyday clutter and frees itself, shown by independent testing.
IIIConditional AutonomyFinishes whole jobs in familiar spaces; struggles at the edges.
To reach Level IIIMost sessions finish without intervention. Rescue is occasional, not routine.
IIAssisted AutonomyThis robot

Maytronics Dolphin Nautilus Titan runs preset routines on its own, and the owner is its recovery system.

Navigation and control

CleverClean systematic scanning
Why this level
- Maytronics documents scheduled cleaning cycles over floor, walls and waterline with a weekly timer and a pick-up mode that parks at the edge.
- Pool Magazine describes CleverClean systematic scanning rather than mapping, and no independent test was found, so it is classified Level II, matching the Nautilus CC Plus.

Robovations Score

Why the score is withheld

Not scored

The Robovations Score is withheld on this record. It is not a low score, and it is not an oversight.

Why

Our assessment did not establish an independent source for 7 of the nine inputs: task completion, coverage and navigation, edge-case recovery, operating envelope, field failure rate, software stability, routine maintenance.

The full assessment note

That leaves nothing measured in its capability. A score missing a whole pillar would not describe the machine, so no number is published.

What would change it

An independent account of its task completion that we have verified.
An independent account of its coverage and navigation that we have verified.
An independent account of its edge-case recovery that we have verified.
An independent account of its operating envelope that we have verified.
An independent account of its field failure rate that we have verified.
An independent account of its software stability that we have verified.
An independent account of its routine maintenance that we have verified.

Reported, not scoredneither measures how well the robot works

Five-year costNot costed

$1,599 on Maytronics' US store; part cadence is unpublished, so no five-year figure is stated.

What leaves the homeDocumented

Maytronics lists control and weekly scheduling through the MyDolphin Plus app; no camera is described. Whether cleaning works without the app, and what data the app collects, was not verified.
