01 Classification
What each one does on its own.
The Autonomy Ladder is the same five rungs for every robot on the site. A rung describes the conditions a robot handles without you, not how good it is.
V
Generalized
Any task, any setting
IV
Environmental
Handles new obstacles without help
III
Conditional
Finishes familiar jobs on its own
II
Assisted
Runs preset routines, needs rescue

02 Assessment
Where they actually differ.
The Robovations Score is nine inputs across three pillars, each weighted as shown and each scored so that more is better. A robot can lead on one and trail on another, which is the point of showing them apart. Cost of ownership and data handling are reported on each robot's own page and are never averaged into the score.

03 Measured against the class
How far apart is a long way?
A number only means something next to the spread it sits in. Each track below is the real range across every classified robot in the class, with the median marked.

04 Ownership
What the numbers leave out.
The trade-off
What each design gives up to be good at what it is good at.
Maytronics Dolphin Nautilus CC Plus
The fine-porosity cartridges that capture silt and sand are the same porosity that loads quickly. In an algae bloom they can fill inside a single cycle, so the after-every-use rinse is what keeps pickup from falling off.
Cord-based operation eliminates wireless convenience but removes dependency on app uptime and cloud connectivity.
Maytronics Dolphin Nautilus CC Pro
Wi-Fi scheduling and 50 ft of range over the Nautilus CC, with no independent test yet of the CC Pro itself.
Who each one is wrong for
Stated by the record itself. A robot being wrong for a household is a fact about fit, not a fault.
Maytronics Dolphin Nautilus CC Plus
- Above-ground or inflatable pools
- Weight and wall-climbing design do not fit above-ground sidewalls. Suction-based robots are standard for inflatable pools.
- Pools with irregular stone or tile edges
- Navigation scans the pool rather than building a map, so covering a heavily irregular shape depends on cycle length rather than a planned route, and crevices along a rough stone edge can be left.
- Owners wanting a cleaner they never handle
- Maytronics instructs owners to rinse the filter after every use, and the unit is lifted in and out of the pool by hand each cycle. There is no self-emptying base.
Maytronics Dolphin Nautilus CC Pro
- Buyers who want independent test results first
- Good Housekeeping and Bob Vila tested the Nautilus CC and CC Plus; no hands-on test of the CC Pro was found.
- Pools longer than 50 ft
- Maytronics rates the CC Pro for pools up to 50 ft in length.
- Owners who want a full-filter warning
- Maytronics' spec table lists no full filter indicator, so the top-access filter is checked by eye.
- Buyers wanting a longer warranty
- Maytronics lists a 1-year warranty for the Nautilus CC Pro.
What stays your job
The upkeep ownership hands back to you, whatever the autonomy level says.
Maytronics Dolphin Nautilus CC Plus
- After every use: Lift the unit out, open the top-load basket, and rinse the filter cartridges with a hose; Maytronics instructs this after each cycle, and the quick water release is built for it.
- After every use: Unwind the 60 ft floating cable and coil it loosely so the next run starts tangle-free.
- Weekly: Check the cable for cuts, kinks, or abrasion.
- Every 3-6 months: Replace the filter cartridges as the mesh degrades (~$28-35 per cartridge).
- Annually: Replace the two rotating scrubbing brushes as the bristles wear down (roughly $45 per set).
- Seasonally: Inspect the drive tracks for wear, then store the unit and its power supply indoors, out of freezing conditions, when the pool is closed.
Maytronics Dolphin Nautilus CC Pro
- After every use: Lift the robot out and empty the top-access fine filter.
- As needed: Check the anti-tangle swivel cable for twists.
- As needed: Inspect the two standard brushes and replace them when worn.
- As needed: Update schedules in the MyDolphin Plus app when pool use changes.
- Seasonally: Rinse and store the robot and power supply out of the sun when the pool closes.
05 Evidence
How much each of these is standing on.
Classifications rest on different depths of evidence. A pre-release assessment and a verified one are not the same kind of claim.
