Maytronics Dolphin Nautilus EON 100 · Wybot S2

Cordless operation removes the cable and the deck-side power supply, but it puts a battery in the ownership picture: charging happens out of the water, and the pack is a part that ages on a machine a mains-fed cleaner would run indefinitely.

SmartMap navigation runs the pool without an operator, but the unit is still placed in the water and lifted out by hand around each session, and it comes out of the pool before anyone gets in.

No dock and no cable keeps the deck clear and nothing trailing into the water, and it also means every cycle starts and ends by hand: the owner lowers the machine in, lifts it out, and rinses the filter. A recharge takes about 3 hours.

Pools longer than 50 feet

Maytronics states coverage for pools up to 50 feet. Longer basins fall outside that envelope, and whole-pool completion above that length is not documented.

Cable-dependent operational preferences

Cordless operation introduces battery scheduling and charge cycles. Owners expecting always-on readiness like corded models have should evaluate runtime and recovery time.

Above-ground or specialty pool shapes

Shallow-ledge design assumes in-ground gunite topology. Above-ground side-wall constraints and irregular small-pool geometry remain unverified.

Pools larger than 3,230 sq ft

Wybot rates the S2 by area, up to 3,230 sq ft of floor and wall. Larger pools sit outside that rating, and 210 minutes on a charge is the ceiling on a single cycle.

Owners who want the machine to empty its own filter

The base S2 ships without a dock and has no self-emptying arrangement. The filter is pulled and rinsed with fresh water after every cycle, and more often through heavy leaf fall.

Owners who want the machine to launch itself

The S2 is lifted into the pool and lifted out by hand. The WYBOT app schedules up to four runs a week on a cycle timer, but the machine has to be in the water when a scheduled run begins.
