Maytronics Dolphin Nautilus CC Plus · Maytronics Dolphin Proteus DX4

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.

The tether takes battery replacement and run-time ceilings out of ownership, and puts a 60 ft cable in the pool and a power supply on the deck that has to reach a GFCI-protected outlet without an extension cord.

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 longer than 50 ft

Maytronics rates the DX4 by pool length, up to 50 ft, and runs it on a 60 ft cable from a deck-side supply. Longer pools sit outside that rating and outside the cable's reach.

Owners who want app control or remote scheduling

The DX4 has no mobile application and no wireless connectivity. Cycles start at the power supply, by hand or on its weekly timer, and there is no status to check from a phone.

Heavy leaf load or silt-laden water

Two-brush capacity caps at moderate debris. Algae-heavy water requires more frequent cartridge changes.
