Dolphin M400 – In-ground pool robot with Wi-Fi

Simplify the maintenance of your in-ground pool with the Maytronics Dolphin M400. This electric robot brushes the floor, walls, and waterline, then collects debris in its top-access filter cartridges.

Complete cleaning for your in-ground pool

The Dolphin M400 is suitable for pools up to 15 m long, or approximately 49 ft. Its active brushing and three brushes work on submerged surfaces during a standard 2 h 30 min cycle. The swivel connector helps limit cable tangling.

Filtration suited to debris

The included set of fine filters and set of ultrafine filters let you adapt filtration to the debris present. Top access makes it easier to remove the cartridges for emptying and rinsing.

Schedule maintenance with MyDolphin Plus

The Wi-Fi connection and MyDolphin Plus app let you manage cleaning and weekly scheduling. For connected features, ensure that a 2.4 GHz Wi-Fi network is accessible to the power supply unit.
