Maytronics Dolphin Nautilus CC Plus · Wybot C2

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.

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.

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.

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.
