Maytronics Dolphin Nautilus CC · Wybot C2

Eight-year-old design: the entry-level price reflects random-path simplicity, and the waterline cycle sold on the CC Plus and Pro is not part of it.

No camera, no mapping: seven preset modes replace a perception system, so coverage quality tracks the mode the owner selects, not the robot’s own judgment.

The added 10-micron filter stage catches finer sediment than a single-basket cleaner, but a three-hour charge against a three-hour runtime still caps use at one cycle per half day.

At 17.6 lb wet, the machine that documents step and slope coverage is also the one an owner has to physically lift out every time.

Skipping the AI camera keeps the price roughly $200 below the C2 Vision, and gives up debris-adaptive path planning to do it.

Pools with high leaf load or organic debris

Random-path navigation encounters debris inefficiently; heavy weekly fallout exhausts filter and requires frequent basket emptying. Dedicated debris skimmers or weighted-floor robots better suited.

Pools needing waterline scrubbing

Coverage is floor and walls; the waterline is not part of the cycle. Scum and algae at the water's edge need manual brushing, or the CC Plus or Pro, which add a dedicated waterline cycle.

Pools longer than 33 ft

Maytronics rates the Nautilus CC for pools up to 33 ft. Longer pools fall outside the rated coverage, and no longer cable is offered for this model.

Owners wanting the deep end or a single zone targeted

Random-path navigation covers the pool over the course of a cycle rather than prioritizing an area. There is no zone selection, so a deep end that collects most of the debris is cleaned on the same terms as the rest.

Pools with no GFCI-protected outlet within cable reach

The cleaner is mains-fed through a deck-side power supply on a 60 ft cable. That supply must plug directly into a GFCI-protected outlet and extension cords are prohibited, so an outlet has to be within reach of the pool.

Pools larger than the 2,152 sq ft rated coverage

Wybot rates the C2 by area, up to 2,152 sq ft, and the machine has no mapping to compensate; larger or irregular pools risk incomplete coverage.

Owners who want the machine to sense and adapt to debris

The plain C2 carries no camera at all; adaptive debris detection and selective zone avoidance are reserved for the C2 Vision, priced roughly $200 higher.

Owners who need back-to-back cleaning cycles without downtime

A roughly three-hour charge against up to three hours of runtime in Eco mode means only one full cleaning cycle fits comfortably in a half day.

Owners who cannot lift a 17.6 lb wet unit from the pool

At 17.6 lb, the C2 is a real lift once it is full of water and pulled from the pool after every cycle, with no self-emptying dock.
